Overlap & Tilemap Problem

[Revan59]

Hi,

I'm currently working on a game and I wanted the player to be slow down , burnt or poisoned according to where he's walking.
So I tried something like this

 

game.physics.arcade.overlap(player,StoneLayer,function(){player.speed = 2;});

 

unfortunatly , the overlap act as a collide when I try this.

I even try that :

 

game.physics.arcade.overlap(player,StoneLayer,function(){return false;},function(){player.speed = 2;return false;});

 

but it ended the same way, the player can't walk on the selected layer whereas he's able to do without it.

 

 

Any Idea ?
