How to use Observer - Trigger Ball - Switch

[ian]

Hi, I prepare simple playground 

http://www.babylonjs-playground.com/#21STMC#0

Can anybody show us how to program switchForBall as observer and ball which trigge switchForBall?


greetings

Ok I try myself with
switchForBall.onCollideObservable.add( function() {
    console.log("Switch collide happend");
});

But nothing happend, it shoul call console.log, but doesn't.
What I'm doing wrong?

player_box.body.grounded = false;				
player_box.body.collisionResponse = 0;
player_box.body.addEventListener("collide", function(e){ player_box.body.grounded = true;
player_box.body.collisionResponse = 1;
};

scene.registerBeforeRender(function(){
	
if(player_box.body.collisionResponse){
   player_box.body.grounded = true;
   player_box.body.velocity.y = 0;
}else{
   player_box.body.grounded = false;	
}

...

Just add an event listener to the physics body for a collide.

nice to see this alternative. I'll try it. Can you tell me which API are you using here? Is this cannon's API?

I know that that is possible. And I like this alternative

scene.registerBeforeRender( function() {
    if (ball.intersectsMesh(switchForBall, false)) {
        console("ball mesh intersect switchForBall");
    }
});

But I really would like to know if onCollideObservable works. Maybe Deltakosh should know. I think he is programirmg babylonjs API.

I think thats what the Collide event listener is?

That should work for Oimo and Cannon
