当Game Maker Studio中的碰撞停止时，如何停止更改实例？

Question

Collision Event with object obj_cu:

for all obj_lamp: change the instance into object obj_lamo_light, not performing events
for all obj_arrow: change the instance into object obj_arrow_move, not performing events

where obj_lamo_light contains 3 sub iamges and obj_Arrow_move contains 3 sub images and I want to change them back to original objects when collision stops

Answer 1

In the obj_lamp_light event, you could check whether or not your collision is still occurring, and change back if not.

if (collision_rectange(x, y, x + sprite_width, y + sprite_width, false, true) == noone)
{
    instance_change(obj_lamp, false);
}
