Reactive Variables

Reactive variable is called rVar in URSA, and all reactive types start with r_ like r_float, r_Vector3 etc. A wrapper around any type that will:

• Raise OnChanged event.
• Fully serialized by Unity and FullSerializer
• Changing value in inspector will raise event as well, thus its fully reactive.
• Can be registered in Console
• Are the only type of variable supported by Config objects.

This functionality however (due to how Unity handles generic types and inspectors) comes at a price.

##If you need to create a reactive variable of custom type, read Creating custom rVars .

These are implemented after UniRx Reactive Properties.

#Usage

//create new rVar<bool> 
public r_bool IsRunning = new r_bool();

//... in some system

void OnEnable() {
   Pool<Player>.First.IsRunning.OnChanged += OnPlayerRunning;
}

void OnPlayerRunning(bool val) {
if(val)
   PlaySound("Running");
}

//... somewhere else

void OrderedUpdate() {
   var playerCfg = Pool<PlayerConfig>.First;
   var player = Pool<Player>.First;
   var input = Pool<Input>.First;

   player.IsRunning.Value = player.Speed > playerCfg.MinRunSpeed && input.PlayerRun;

}
