1. Whats the code to MUTE all sounds ?
2.Whats the code for changing between Full and Window screen ?

that is set on my "Z" press event
background_assign(0,ba_evil)
and it doesnt change
whats wrong ?

So my room view folows an object,and in the game i have a instance change, when i change the instance in the game view stops following me,so how can i make it follow my both objects? i thought of changeing the following object when i press the "transformation" button,but i dont know the code...

how to make a ball that will ROLL when vk_right is pressed. ?

so i added lifes to my game and when i start it it freezes... heres the code of the object: Information about object: obj_kitty
