Haxe Pixi - InteractionManager mouseMove is too damn high !

[T0T0S]

Hello,
 
I've got a problem that is starting to impact the performance of my game and I found through profiling that the MouseMove & ProcessMouseMove,

are binded to the window "mousemove" event.

 

They do fire correctly, but I simply need them to fire once per frame. ( They fire 5 - 10 times per frame which is normal )

 

Is there a way to do this in pixi with interactionFrequency, or do I need to do some hack ?

 

Thanks in advance

Ok, so there are two things:

 

1) it fires on real move move

2) it fires in onUpdate() timer 

 

Yes, its too damn high, I think

 

I think you have to patch InteractionManager yourself before we fix that thing, its not that hard. You will implement all this code anyway

Alright,

 

Thanks Ivan, I'll find a work around, 

 

Still, it would be nice to have it already built-in Pixi.

you need to check sturcture of containers..

 

pixi is always check all containers..  so if you use containers not having some plan to struct. you can be encountered....

 

if you reduce containers  or if you use interactveChildren parameter.. 

you can optimize more..

I've made a work around that works well

var mouseMaxCallPerFrame = 1;
var mouseEventCallThisFrame = 0;

var renderer = Pixi.Detector.autoDetectRenderer(1600, 900, {});
var oldMoveFunction = renderer.plugins.interaction.onMouseMove;

var newMoveFunction:Dynamic = function(event):Void {    
	if (mouseEventCallThisFrame >= mouseMaxCallPerFrame) 
		return;   
	++mouseEventCallThisFrame;  
	oldMoveFunction (event);
}

renderer.plugins.interaction.onMouseMove = untyped newMoveFunction.bind(renderer.plugins.interaction);

renderer.plugins.interaction.setTargetElement(renderer.view);

Just remember to reset to 0 "mouseEventCallThisFrame" at every game loop.
