Make an easy and fast pause screen for your game

Hi all, in this video tutorial i will show you how to add a pause screen for your game easily.
Enjoy:

The codes : instance_deactivate_all(1) : This will deactivate all the instances in the room. The 1 that i have made mean that the current instance will not be deactivated it can be also true (true = 1), if you put 0 or false it will be deactivated too. instance_activate_all() : This will activate the instances in the room.  draw_text(x,y,text) : This code will draw a text at the room, it must be used in the draw event.
