Detect collision end between 2 collision group

[Phempt]

Hi guys, I've a character (collision group 0) that can jump on a platform (collision group 4).

 

This is my collide function:

else if (other.collisionGroup === 4) {            if (player.last.y + player.shape.height / 2 <= other.position.y - other.shape.height / 2) {            player.onGround = true;            player.mass = 1;            player.velocity.y = player.velocityLimit.y;            }            else return false;}

is it possible to detect when collision between character and group 4 end in order to set player.onGround on FALSE?

 

Thank you

I solved with this 3 lines in the update function:

//console.log("last: "+lastPosY+" new: "+player.position.y);        if (player.position.y > lastPosY) { player.onGround = false; }        lastPosY = player.position.y;

is there a better way?

There is afterCollide function on body, that is called after collision is solved. Maybe that can help you?

I'll try because I don't like that the update function continuously checks the y variations.

I tried but in my case the resources usage is the same.

 

Thank you anyway
