Hi,
I’m porting a simple game from another engine that uses some kind of equalizing speed so it will be the same regardless of sytem spec.
I found there’s a solution in 2D (Starling) but not sure how this would be something similar with Away3D.
private function update(e:EnterFrameEvent):void
{
deltaTime = e.passedTime; //passedTime is starling attribute
}
...
Player.x += movementSpeed * deltaTime;
I know there’s deltaTime for Away3D but I’m not sure how to use it. I can’t find any examples on web either (yet).

Hello,
I’m not sure of what I’m going to write so I think you should wait for a confirmation
but
if you use an “animator” class ( for exemple the skeleton animator ) the motion is based on the time given by the function getTimer()
in the animatorBase.as :
private function onEnterFrame(event:Event = null):void
{
update(getTimer());
}
You can find some information about the getTimer here
http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/utils/package.html#getTimer()
but basicaly it returns the time spent since your application is runing. Whatever the system specs are.
So if your issue is to be sure that the motion will have the same speed on all the systems, you can trust in the animator class or build your own class based on the time returned by this function.
I hope this can help you

Thanks. I was wondering why the above is not hooked in the player movement?

This is what i would use
private var view:View3D;
protected function update(event:Event):void
{
view.camera.moveForward(view.deltaTime * 10); //move camera forwards 10 meters per second
view.render();
}

Hey thanks therealloft! So I can just do the same for let’s say AI like this?
enemy.moveForward(enemy.deltaTime * 10)
this sure helped a lot.

if you create a public static var to hold it, it be easyier like this
public static var deltaTime:uint = 0;
protected function update(event:Event):void
{
view.render();
deltaTime = view.deltaTime;
}
Then all you have to do from any part of you app to find deltaTime is call
Main.deltaTime
hope this helps
