Cloud Variables

Overview

Cloud variables are variables that persist across worlds. They work in a similar nature to dynamic variables but instead of relying on parenting or the world hierarchy, they instead rely on paths and user/group ownership. You can think of them in a similar way to a settings or configuration file for your favorite game. Cloud variables are more lively than this though as they are synced between sessions, worlds and even your Resonite dash.

For a quick-start guide to using cloud variables, see this tutorial: How To Use Cloud Variables.

Cloud variables are comprised of two parts:

• Definitions - Settings and configuration: owner, name, type, permissions, and default value.
• Values - Actual values per user.

Cloud Variable Definition

A cloud variable definition is made up of 4 Parts:

• A path/name E.g. AwesomeGadget.Version or PartyWorld.highQualityLights
• Data type
• Permissions
• A default value
  • Default value would be an output of the To String node with spaces removed. An example would be ColorX, which through To String results in: [1;1.23;0;1;sRGB]

Definitions can also be registered against a user or a group. Registering a definition against a group has some benefits such as:

• Higher limits
• Additional permission capabilities

Default Values

When creating a definition, you supply data and configuration in a series of stages with each command. Just in case you forget or omit a command here are the default values for various properties of a definition:

• Read and write permissions will default to variable_owner
• List permissions will default to definition_owner
• If no default value is specified, Resonite will return the default value for this data type as defined in C#.

Cloud Variable Values

Each cloud variable definition can have multiple values, each value is tied to an individual Resonite user or group. A value just contains its value and has no details about the definition. You can think of it like a table with two columns an owner ID and the value.

For example if a cloud variable definition was created with a data type of string and a name of "Favorite Fruit" then you can imagine its values looking like this:

Favorite Fruit
Variable Owner ID	Value
U-Frooxius	Strawberry
U-Nexulan	Orange
U-Shifty	Pineapple
U-ProbablePrime	Blueberry
G-MyGroup	Banana

The last row shows a value that is specific for a group. This is only possible for cloud variables that belong to a group.

Variable owner IDs (user IDs or group IDs) with spaces need to be written with a hyphen. Example: Group "My Group" becomes "G-My-Group". Always double check your user ID and group IDs they can be completely different from a user's/group's displayed name.

Using Cloud Variables

Before using cloud variables they must be created and registered. This is done by sending commands of various types to Resonite Bot. These commands create and register a #cloud variable definition with Resonite. Once registered, cloud variable values can be read, written and manipulated against this definition using ProtoFlux & components.

Usage Notes / Warnings

• Variable definitions are heavily cached and will typically take several minutes to update. It's recommended to set them up fully in advance.
• Reads & writes are buffered, batched and cached and will take a bit to propagate.
• A current limitation of the cloud variable system is that they won’t be synchronized in real time across different sessions, unless they run on the same host/user. If you host multiple worlds/sessions on a single headless (or your own computer), the changes to the cloud variable will sync in real time within those sessions.
• If different users host the same world, changes in one world won’t be immediately reflected in another and will take a few minutes to refresh. The current plan is to add full real time synchronization in such cases by integrating SignalR into the Resonite cloud infrastructure, which will help the cloud scale better for other things like active sessions or the messaging system as well.
• Current limits, permissions, and other aspects are subject to change.
• Changing data types is possible, however already stored values are not affected.

Limits

Cloud variables do not take up any storage, but they do have limits.

Definition limits

Limit Type	Limit
Users	256
Groups	8192

These limits only apply to created variable definitions and not to values stored within them. For example a variable definition of "U-ProbablePrime.FavoriteColor" can still have an unlimited number of values for it for each user's favorite color.

Rate limits

When reading/writing from Cloud Variables the following limits are in place

ProtoFlux

With ProtoFlux, as the read or write is triggered by an impulse the read/write operation occurs immediately at the time the nodes receive the impulse.

Due to this the read/write process can be performed up to 30 times a minute.

When reading or writing data to a variable using ProtoFlux, the restrictions set in place for the defined variable exist for the ProtoFlux nodes. If the nodes exist in your local space, then the nodes can write/read to variables which only allow reading/writing inside a safe context.

Components

Cloud variable components operates on a schedule, periodically refreshing the values in both directions. These values are not that fast right now but with further enhancements to our SignalR^{[Citation needed]} use, these values will update more promptly.

Currently:

• Reads occur every 5 minutes
• Writes will be delayed(buffered) and sent every 30 seconds
  • If the value on the component changes more frequently then the most recently set value at the time of the write will be sent to the cloud.

Update Rates

Please read the section above limits.

Supported Datatypes

When creating cloud variable definitions a valid type for them needs to be specified. The supported data types are listed below but generically any primitive data type is supported. Reference data types are not supported as references only work within one defined world/session.

Supported Cloud Variable Data Types

bool	bool2	bool3	bool4
float	float2	float3	float4	float2x2	float3x3	float4x4
int	int2	int3	int4
long	long2	long3	long4
double	double2	double3	double4	double2x2	double3x3	double4x4
uint	uint2	uint3	uint4
ulong	ulong2	ulong3	ulong4
short	ushort
byte	sbyte
floatq
doubleq
color
datetime
timespan
decimal
enum	*
string	*

• Enum:
  • You can now also use Enum types, the cloud variable definition must be set to string to sync properly. Once created you can use ProtoFlux & components with their DataTypes set to the enum you wish to use. For example CloudValueField<ShadowType>.
• String:
  • You can specify a maximum length for the string when setting the data type.
  • The format is string:<max_length>.
  • By default, strings have a length of 256 characters. The maximum length is 8192.
  • Both user and group variables are affected by these limits.

More datatypes may be supported in the future.

Permissions

Cloud variable permissions are composed of two parts:

• Action permission - The type of action that a permission group can carry out.
• Group/type permission - A group or classification of user.

When reading and deciding on a permission set do remember that in most cases, each user has their own value for a cloud variable.

As an example in the following command: /setUserVarPerms test.color read,write,list anyone. The actions are "read, write and list" and the permission type/group is "anyone".

Action Permission

Action Permission	Description
read	Grants the ability to read values of a cloud variable.
write	Grants the ability to write values of a cloud variable.
list	Grants the ability to list all values or a variable.
all	Grants all above permissions at once.

You can also specify multiple permissions at once, separated by a comma so for example /setUserVarPerms test.color read,write,list variable_owner would set the read,write and list permissions on the test.color variable to variable_owner.

Group/Type Permission

Common Definition Permissions

These permissions, can be used with both user and group owned definitions.

Permission Type	Description	Locations	Limitations
anyone	Anyone can read/write this variable's values. This is recommend for reading public variables but not recommend for writes as anyone can change anyone's value.	Everywhere.	- Cannot be used with write permissions on User owned definitions. - Cannot be used with list permission on user owned definition.
definition_owner_only	Only the user/group who defined the variable can read/write their own singular value. Useful for announcement/version control systems.	Userspace/safe contexts only.	None.
definition_owner_only_unsafe	Only the user/group who defined the variable can read/write their own singular value. Useful for announcement/version control systems.	Everywhere.	None.
variable_owner	Only the user who owns the variable value can write/read their own value. In this case the definition owner cannot read/write values for other people.	Userspace/safe contexts only.	Cannot be used for list permissions
variable_owner_unsafe	Only the user who owns the variable value can write/read their own value. In this case the definition owner cannot read/write values for other people.	Everywhere.	Cannot be used for list permissions

User Definition Permissions

These permissions, can only be used with user owned definitions.

Permission Type	Description	Locations	Limitations
definition_owner_only_contacts	TODO	Userspace/safe contexts only.	Cannot be used for list permissions
definition_owner_only_contacts_unsafe	TODO	Everywhere.	Cannot be used for list permissions
variable_owner_only_contacts	TODO	Userspace/safe contexts only.	Cannot be used for list permissions
variable_owner_only_contacts_unsafe	TODO	Everywhere	Cannot be used for list permissions

Group Definition Permissions

These permissions, can only be used with group owned definitions.

Permission Type	Description	Locations	Limitations
definition_owner	Only the group who defined the variable can read/write it.	Userspace/safe contexts only.	None.
definition_owner_unsafe	Only the group who defined the variable can read/write it.	Everywhere.	None.

List Permissions

Due to the "list" permission having very limited valid permissions it is easier to list what permissions are allowed for list:

• anyone - Only on group based definitions.
• definition_owner
• definition_owner_unsafe

Safe Contexts

In most cases within Resonite, anyone can observe or even manipulate what you're doing. These are unsafe contexts. When in places such as userspace, where the Resonite dash is located, no one can see or modify what you're doing. This is a safe context.

Permission Matrix

This table shows you which permission can be applied to which action permission, for user and group variables.

	User Read	User Write	User List	Group Read	Group Write	Group List
anyone	Yes	No	Yes	Yes	Yes	Yes
definition_owner_only(_unsafe)	Yes	Yes	No	Yes	Yes	No
definition_owner(_unsafe)	Yes	No	Yes	Yes	Yes	Yes
variable_owner(_unsafe)	Yes	Yes	No	Yes	Yes	No
definition_owner_only_contacts(_unsafe)	Yes	Yes	No	No	No	No
variable_owner_only_contacts(_unsafe)	Yes	Yes	No	No	No	No

Cloud Variable Commands

To create, update and modify cloud variables you will need to use commands. These commands can be sent to the Resonite Bot within Resonite, you'll be able to find it in your contacts section.

Command arguments inside brackets () are optional. All other arguments are required.

Creating Definitions

User Definitions

• /createUserVar <path> - Creates a variable definition with the given path.
• /setUserVarType <path> <type> - Sets the variable definition's data type.
• /setUserVarDefaultValue <path> <value> - Sets the default value for a definition.
• /setUserVarPerms <path> <action permission> <permission type> - Sets the permissions for a definition.

There is also a command which can create a definition in one line:

• /createUserVar <path> <type> <default value> <read perms> <write perms> <list perms>

Group Definitions

• /createGroupVar <group> <path> - Creates a variable definition with the given path.
• /setGroupVarType <group> <path> <type> - Sets the variable definition's data type.
• /setGroupVarDefaultValue <group> <path> <value> - Sets the default value for a definition.
• /setGroupVarPerms <group> <path> <action permission> <permission type> - Sets the permissions for a definition.

There is also a command which can create a definition in one line:

• /createGroupVar <group> <path> <type> <default value> <read perms> <write perms> <list perms>.

Recommendations

Generally we recommend using the command which creates the entire definition in one go, this ensures you do not forget any steps or parts which can cause the variable to be unusable.

Reading Values

For reading values using ProtoFlux / Components, see this later section.

User Values

• /getUserVar <path> - Gets the definition for a variable (type, perms, default value)
• /getUserVarValue <definition_owner> <path> <target user> - Gets a user's value for a definition.
  • Example: /getUserVarValue U-ProbablePrime testing.bool U-ProbablePrime would get Prime's value for their variable testing.bool
• /listUserVars (<user>) - Lists variable definitions of a user (default: yours). Requires list permission.

Group Values

• /getGroupVar <group> <path> - Gets the definition for a variable (type, perms, default value)
• /getGroupVarValue <group> <path> (<target user>) - Gets a user's (default: yours) value for a definition.
• /listGroupVars <group> - Lists variable definitions of a group. Requires list permission.

Writing Values

When setting/writing a value, ensure that your permissions are set correctly.

For writing values using ProtoFlux / Components see this later section.

Writing Values with User owned Definitions

/setUserVarValue (<user>) <path> (<target user>) <value> - Sets an individual user's value for a definition.

For example: /setUserVarValue U-ProbablePrime testing.bool U-Frooxius true would set the value of testing.bool to true for Frooxius' value of ProbablePrime's definition.

Writing Values with Group owned Definitions

/setGroupVarValue <group> <path> (<target user>) <value> - Sets an individual user's value for a definition.

For example: /setUserVarValue G-Cheese testing.bool U-Frooxius true would set the value of testing.bool to true for Frooxius' value of the group Cheese's definition.

Setting Complex Values

For complex values, you may struggle to know what to enter for this command. Here are some examples which may help:

• For complex strings, surround the value in quotation marks ". E.g. "My Cool Value".
• For float3 use [1; 0; 1]
• For colors use [1; 0; 0; 1]

Deleting Definitions

You can delete definitions using the following commands:

• /deleteUserVar <path> for user variables.
• /deleteGroupVar <group> <path> for group variables. (Currently broken, see Issue #537)

This command deletes both the definition and all values linked to that definition. It also takes a while(around 30 minutes) for this command to fully execute as it needs to clear values, caches and other systems of the definition and values.

Definition Examples

User Boolean

Create a User variable of type boolean that anyone could read and the owner (each user for their own copy) could write from user and world space:

/createUserVar testing.enabled
/setUserVarType testing.enabled bool
/setUserVarPerms testing.enabled read anyone
/setUserVarPerms testing.enabled write variable_owner_unsafe

User Color

Create a User variable of color type that only the owner could write from userspace and read from everywhere:

/createUserVar testing.myColor
/setUserVarType testing.myColor color
/setUserVarPerms testing.myColor read variable_owner_unsafe
/setUserVarPerms testing.myColor write variable_owner

Group Boolean

Create a Group variable of boolean type that only the owner could read and write from everywhere:

/createGroupVar MyGroup testing.enabled
/setGroupVarType MyGroup testing.enabled bool
/setGroupVarPerms MyGroup testing.enabled read,write variable_owner_unsafe

Working with cloud variables

Components

ActiveUserCloudField`1 (Component) - Like CloudValueField, but overrides OwnerId with local user.

ActiveUserCloudValueVariable`1 (Component) - Like CloudValueVariable, but overrides OwnerId with local user.

CloudValueField`1 (Component) - Uses target field to store the value, otherwise similar to CloudValueVariable.

CloudValueVariable`1 (Component) - Represents the cloud variable, can set OwnerId manually.

CloudValueVariableDriver`1 (Component) - Drives target field with the value of the specified cloud variable. Overrides OwnerId with local user.

ProtoFlux Nodes

Write Cloud Variable`1 (ProtoFlux Node) - On impulse, writes the specified cloud variable for specified owner.

Read Cloud Variable`1 (ProtoFlux Node) - On impulse, reads the specified cloud variable for specified owner.

Headless Sessions and Auto-Startup World Options

Cloud variables can be used with headless server configuration files and start-up configuration files in a number of ways:

• Configuring roles in a session.
• Allowing/denying users from joining/accessing sessions.
• Provide custom denial messages for why a user is denied access to your sessions.

These options are NOT available in the UI within Resonite and require advanced setup from outside of the game.

We recommend using a group variable for these setups, due to the permission requirements. You can potentially get away with an appropriately configured user variable but group variables will give you the most control.

To set these up, you need to add the described parameters below, to your configuration JSON files.

Roles

To configure roles using cloud variables, add a roleCloudVariable parameter to your world start-up/headless session configuration. Its value should be the full path of the cloud variable you want to use. The session will then use the cloud variable to determine which role the user has.

When doing this you need to keep in mind a few things:

1. The variable data type must be a string.
2. It is strongly recommended that you use the definition_owner permission group for this variable. Other permission groups may allow users to override their roles.
3. If no value is set for the variable and a user, the other methods for determining the role will be used.

An example setup would be:

G-Cheese.awesomeHeadless.userRoles
Variable Owner ID	Value
U-Frooxius	Admin
U-Nexulan	Builder
U-Shifty	Guest
U-ProbablePrime	Spectator
U-Vegasx	Spectator

With the corresponding JSON property which needs to be added being: "roleCloudVariable": "G-Cheese.awesomeHeadless.userRoles"

Access

There are a few variables and settings which can control access to headless sessions.

Allowing User's Access

To configure access to a headless session, using cloud variables add a allowUserCloudVariable parameter to your world start-up/headless session configuration. Its value should be the full path of the cloud variable you want to use. The session will then use the cloud variable to provide access to the session.

This option take precedence over all other checks, including regular session settings such as max users and visibility.

When doing this you need to keep in mind a few things:

1. The variable data type must be a bool.
   1. If it is set to true, the user will be allowed to join the session.
   2. If it is set to false, or a value is not present, the other methods for determining access will be used.
2. If its value is true, the server will allow access to the user.
3. This is the equivalent of sending an invite to the user.
4. Users can join regardless of the MaxUsers setting.
5. Users can join even if the session is private. They will need a link to the session though.

An example setup would be:

G-Cheese.awesomeHeadless.userAccess
Variable Owner ID	Value
U-Frooxius	true
U-Nexulan	true
U-BadGuy	false

With the corresponding JSON property which needs to be added being: "allowUserCloudVariable": "G-Cheese.awesomeHeadless.accessControl"

Denying User's Access

In a similar manner to allowUserCloudVariable, you can use denyUserCloudVariable to deny a user access to your world start-up/headless session configuration. Follow the guide above for allowing access but use denyUserCloudVariable instead. When a value for a user is true, they will be denied access.

When true, this option take precedence over all other checks, including regular session settings such as max users and visibility.

An example setup would be:

G-Cheese.awesomeHeadless.userAccess
Variable Owner ID	Value	Description
U-Frooxius	false	Allowed Access
U-Nexulan	false	Allowed Access
U-BadGuy	true	Denied Access

With the corresponding JSON property which needs to be added being: "denyUserCloudVariable": "G-Cheese.awesomeHeadless.userAccess"

Joining Control

In addition to the above options, you also have the option to use requiredUserJoinCloudVariable. When this option is added to your world start-up/headless session configuration, its value for a user will be checked when they join. If it is true then the user will be allowed to join. If it is false then they will not be allowed to join.

Do note that this option does NOT take precedence over other session checks. Even if this value is set to true, if the session is full (at its maximum user count) the user will not be allowed in.

An example setup would be:

G-Cheese.awesomeHeadless.userAccess
Variable Owner ID	Value
U-Frooxius	true
U-Nexulan	true
U-BadGuy	false

With the corresponding JSON property which needs to be added being: "requiredUserJoinCloudVariable": "G-Cheese.awesomeHeadless.userAccess"

Deny Messages

When using requiredUserJoinCloudVariable with your headless, you can use a second configuration element in the configuration file; requiredUserJoinCloudVariableDenyMessage.

This allows you to specify a single message that is sent to users who are restricted from joining due to their value being absent or false, in the variable defined in requiredUserJoinCloudVariable.

You must use, requiredUserJoinCloudVariable for this to work as they are linked together. These systems cannot be combined with other cloud variables or other access controls.

These options may be confusing at first but it is useful for controlling session access, without bypassing regular checks such as visibility and max user counts. We often see it uses for things like events which require registration such as conventions.
