So you know how Terkoiz has that effect in..lets say the Shock series, how if a part of the wall breaks, how it looks. Would anyone like to give me a helpful tutorial on how to do so? I tried searching the "Flash tutorials" thread, but couldn't really find anything. Please help. Thanks, bye.

This tutorial teaches you how do draw and animate cracks but it's mostly about combos. Skip ahead for the ground crack effect.

I go to %800. Then I select the smallest or second smallest brush. Then just make cracks depending on certain elements like force of impact, volume, ect. Just test around with it. Look at animations that have cracks on the ground and walls. Btw that link FreakingGecko posted is a good one.

When watching the Shock animation, right click>uncheck the play>right click>zoom in 3-4 times>examine.
