Fist of all, I'm really sorry for my bad English and I pretty new to game maker .
I have 2 object in the game : obj_apple and obj_door( I unchecked visible box) my question is how can I make an obj_door visible in the room when all the obj_apple are destroyed?
对象obj_door
, Step
事件,放置代码( Add event
-> Step
-> Step
-> 选项卡Control
-> 部分Code
,第一个图标(执行代码)):
if !instance_exists(obj_apple) visible = true;
Another option, so you aren't making a check in every step event, is to put the check for the number of obj_apple
in the destroy
event of obj_apple
.
For example, in the destroy
event of obj_apple
you would have:
if (instance_number(object_index) == 0) {
with (obj_door) {
visible = true;
}
}
