This read-only array returns the y coordinate of every point detected in a collision between two physics-enabled instances.
NOTE This variable is only available in the collision event of a physics-enabled instance.
NOTE This variable does not hold a real GML array, so you cannot run any array functions on it or serialise it (convert it to a string). The only operation you can run on it is accessing a value at an index, with the phy_collision_y[index] syntax.
phy_collision_y[index]
Real (single-precision floating-point value, or undefined if the instance doesn't have physics enabled)
Collision Event
for(var i = 0; i < phy_collision_points; i += 1;)
{
part_particles_create(global.Sname, phy_collision_x[i], phy_collision_y[i], global.Spark, 5);
}
The above code creates particles at all the defined points of a collision between two physics-enabled instances.
