[Req] Support triggering property changes on entities

[Powback]

Similar to how entities have :FireEvent(event), they should also have something like :FireField(field, value).

Example:

In this case, we should be able to do something like

ReferenceObjectEntity:FireField('Visible', true)

I'll come back and update the issue with how it works exactly at a later time.

Looks like we're after "PropertyChanged", as demonstrated here:

And in fb::LogicVisualEnvironmentEntity::propertyChanged
or fb::ServerStaticModelEntity::propertyChanged

You want to trigger property changes or do you want to listen for them? I've already been working on supporting the former. The latter is a bit more complicated.

[Powback]

Triggering it would be enough for my needs.

You need to have a proper FireEvent which supports events like fb::ServerPlayerEvent, fb::ClientPlayerEvent, and possibly more.

An example of an event that needs fb::ServerPlayerEvent is fb::ServerInputRestrictionEntity which might be useful in some vext mods.

@txt231 you can open a separate issue for that request.

Build 13443 adds a PropertyChanged(...) method to trigger property changes on entities. It can be called as follows:

ent:PropertyChanged(1234) -- FNV hash of the event name
ent:PropertyChanged(1234, value) -- see below for details on values
ent:PropertyChanged("SomeProperty")
ent:PropertyChanged("SomeProperty", value)

Currently, only some properties support setting a value of a specific type. Most property listeners that I looked at seem to only do internal changes and not read any values. See the table below for reference.

Property Name	Value Type
Transform	LinearTransform
ControllableTransform	LinearTransform
TransformIn	LinearTransform
Enabled	bool
Visible	bool
BoolValue	bool
BoolIn	bool
IntValue	integer
IntIn	integer
FloatValue	float
FloatIn	float
Vec3In	Vec3
Vec4In	Vec4
Team	TeamId
