        To use this code, copy "crate.wdl" and put it into your work folder.  Then in the main level script, 
in the includes put:

include <crate.wdl>;

and then put the crate.mdl in your level and scale it up to size and give it the 'crate' action.  Voila!

Now you can shoot the crate and it blows up in gibs. And if u stack some crates above it, they will come down.

If u want ammo or weapons inside, put the designated model in the crate and then when the crate explodes, the stuff will be waiting for you.
