Event listener for changing enabled

[Lukas_Zahumensky]

Hi!
I want to ask if there is a way to create event listener that e.g. fires an event if some entity’s enabled is chnaged from true to false and vice versa.

Oddly enough, we don’t

Please do make feature request for this on the engine github repository as that would be pretty useful

You could monitor the state event as a workaround. Check out this thread as an example:

Is there an event fired for when an entity is enabled/disabled

There is an event that is fired (surprised it isn’t in the documentation). However, if an entity starts off disabled, the initialize function of the scripts attached are not called. It gets called on the first time the pc.script gets enabled. So the way around this is to call the callback in the initialize function and also subscribe to the event. App.prototype.initialize = function() { this.onEnable(); this.entity.on('enable', this.onEnable, this); }; App.prototype.onEnable =…

That works if you are coding in a script instance attached to that entity.

But still it can be quite useful to have this per entity without that requirement. I imagine since the ‘destroy’ even is there, an entity state event makes sense.

For now I have if statement (where I control the state of entity.enabled) in update function as a workaround and it works
