Learn how to destroy a breakable wall with the help of a triggered explosion.

Posted by Silverfisk on Feb 5th, 2010
Intermediate Mapping/Technical.

First we create a wall and cut out a shape in it that we tie to the func_breakable entity. Then we create the env_explosion entity and set up a trigger_once to trigger the explosion when activated.

Please give me a comment telling me what you think.
Also, don't forget to give me tutorial requests!

Not sure if your a model or a Google sketch-up user but Valve now has a plugin for exporting models so that you can compile them and stick right into your maps :) A tutorial on this process would be greatly appreciated

If your sticking with hammer then a tutorial on how to set up and use cube maps might be nice

Yea optimization would be nice I make sufficiently large maps and they are unoptimized since I am a noob to that stuff so I hear they run slow which is dissapointing.
