i using phaser-matter-collision-plugin to phaser game.https://github.com/mikewesthad/phaser-matter-collision-plugin .
How to set Collision Filter ? filter collision between two bodies, make the sprite body thought run thought another sprite body.
I try to set .setSensor(true) to some sprite.body , but I think it is not the best way to solve the problem.
any idea??
`const player = this.matter.add.sprite(0, 0, "player");
const EmptyBody = this.matter.add.sprite(200, 0, "EmptyBody");
this.matterCollision.addOnCollideStart({
  objectA: player,
  objectB: EmptyBody,
  callback: eventData => {
   // anyidea to set  two bodies through thier body ???
  }
});`
Thank you very much??
             
            
              
                
            
           
          
            
            
              
  
  
    It may help to assign a new collision category when the pointerdown function is called. Something like: 
cat1= this.matter.world.nextCategory();
cat2= this.matter.world.nextCategory();
platform = this.matter.add.rectangle(100, 46, 40, 10, {
		isStatic: true,
	});
ball = this.matter.add.circle(100, 8, 6, {
		isStatic: true
	});
platform.setCollisionCategory(cat1);
ball.setCollisionCategory(cat2);
ball.setCollidesWith(cat2);
this.input.on("pointerdown", function() {
		ball.setStatic(false);
		…
   
 
This might help. Set your categories outside of the collision function, and then change the categories inside the function. You may not want to add a collision filter to the player though. Just provide a category for the EmptyBody, and then force it to only collide with its own category when it collides with the player.
