This function gets the density value for a bound fixture.



Argument Description
fixture the id of the bound fixture

Returns: Real


When you bind a fixture to an instance using physics_fixture_bind this returns an "id" for the bound fixture. You can use this id to get the restitution (the "bounciness" property) value of the bound fixture, not the "base" fixture, at any time using this function.


var rest = physics_get_restitution(fix_id);
physics_set_restitution(fix_id, rest * 2);

The code above gets the current restitution value for the bound physics properties of the instance and then sets them to a different value.
