Glass that starts out broken

Broken glass that breaks when the map starts

This tutorial assumes you already know how to create breakable glass, if not then follow that tutorial first.

• Open one of your maps or make a new one.
• Make a func_breakable_surf with a frame around it (as if you are making a normal breakable window).
• Set up an env_explosion in the middle of the window, then change the options of the env_explosions as follows:

Class: env_explosion
Keyvalues		Comments
Name		..anything you want as long as you know what it is
Magnitude	1

• Then in the flags tab, change the flags as follows:

	Flag
		No fireball
		No smoke
		No decal
		No sparks
		No sound
		No fireball smoke
		No particles
		No Dlights

• Set up a logic_auto near the env_explosion (it doesn't matter where you put it, but I recommend that you put it in a convenient place)
• Change the entity outputs for the logic_auto as follows:

		My output	Target entity	Target input	Parameter	Delay	Only once	Comments
	File:Entity-output-iconOnMapSpawn.png	env_explosion	Explode			Yes	env_explosion is the name you typed for that entity	{{{8}}}
								{{{8}}}

• Then in the flags tab, change the flags as follows:

	Flag
		Remove on fire

• Test your map! When it loads the env_explosion will break the glass leaving the jagged glass edges on the side of the frame.
