View source for Template:FireOn user information

<onlyinclude>For best practice, this should never be left <code>null</code> or evaluated differently based on the user (e.g. via [[ProtoFlux:LocalUser|LocalUser]]). If this input is <code>null</code> and the node is parented under a user, then the impulse will be fired for said user. If this input is <code>null</code> and not parented under a user, or if this input evaluates differently for different users, then the impulse will <em>tend to</em> be fired for the first user that sees the change in value. This is usually the one who caused the change in the first place. This could cause inconsistent behavior unless carefully managed. If the desired behavior is for an impulse to fire by every user that detects a change for them locally, then use the local version of this node, which is linked at the bottom of the page.</onlyinclude>
== Usage ==

For use on [[ProtoFlux:FireOnChange]] and similar nodes.
