How to check collider and not collider between two objects?

[Milton]

I think you just need to reset the flag at the end of update, see also

Collision enter - exit event?

Maybe you want to set a flag of some sort inside the collision callback and reset it at the end of the scene’s update method or as soon as the sounds ends.

candosomething = false;
this.physics.add.collider(player, platforms, check_collision, null, this);

function check_collision (player, platforms)
{
    candosomething = true;
}

function update() {
    ...
    if (candosomething) {
    }
    ...
    candosomething = false;
}
