Alright. I guess it's alright that you don't know, not everyone knows everything. Events can make things happen. Say you want a brick to shoot a tank shell. Click the first box in events and set it to "Onactivate". Set the next to "Self". Set the third to "Spawnprojectile", enter a number in any of the boxes (Try 10 or so), and set the last box to "Tank shell". Hit Send, click the brick, and enjoy.
