Mesh UVRaycast Portal component as seen in the Scene Inspector

This component allows users to interact with objects through a camera.

Usage

Fields

Name	Type	Description
persistent	Bool	Determines whether or not this item will be saved to the server.
UpdateOrder	Int	Controls the order in which this component is updated.
Enabled	Bool	Controls whether or not this component is enabled.
Offset	Float	How far back from the camera's actual view direction to project from
RayExit	IUVToRayConverter	Usually a camera
UVOffset	Float2	The added offset to the UV point you hit on the mesh before it's projected out; best to keep this (0,0) unless needed
UVScale	Float2	The multiplied offset to the UV point you hit on the mesh before it's projected out; best to keep this (1,1) unless needed
RepeatUV	Bool	Whether to repeat between the 0-1 range when the laser on the source hits a UV beyond 0-1
OverrideHitTriggers	Nullable`1<Bool>	Whether to hit colliders, requires Filter to have a sync delegate, but doesn't need to be enabled for this component to work
Filter	Func`3<ICollider, Int, Bool>	This is a field usually used by the dash manager in local space. Very hard to use, and is not required at all
FilterMode	FilterCombineMode

Behavior

• The camera needs to be in orthographic mode for best results. it still works in perspective but because of perspective warping it only works well in the center. This component is used for the dash, but can be utilized in real world space, allowing for some interesting effects.

• This component only works with mesh colliders. The type of mesh does not matter, since it uses the UVs; the mesh triangles have to determine what point on the camera output to project the raycast out of.

• The mesh collider can only be a front sided collider for this component to work.

• Only user interaction lasers are allowed to pass through, and only press button interactions.

Examples

To set up this component, you will need a camera. One can easily be made by creating a new camera through the Dev Tool's "Create New" menu. The camera component on the newly created object can be put on a new slot and set to the side. The box collider needs to be replaced with a mesh collider. The mesh collider will automatically use the quad mesh on the camera. Now you are able to press buttons through the camera. It works way more consistently in orthographic mode.
