I want to know how I can make it so when something happens I can disable left click, but then enable it again as well. How can this be done?

Use this.

What it does is check if ammo is higher the 0 then it allows the mouse button to be pressed.

if ammo>0 and mouse_check_pressed(mb_left) then{//shooting code\}
