Keyboard Event for <any key> Key:

execute code:

//simple movement code

if keyboard_check(vk_left)
&& place_free(x-4,y)
&& x > 0
{ x-=4 }

if keyboard_check(vk_right)

Key Press Event for <Enter> Key:

execute code:

global._room_persistent = room_persistent
room_persistent = 1
//remember the rooms persistency to return it back

//initialize the state of the variable

Collision Event with object obj_player:
