Adding a Bombsite to Your First Map
By Matrixfan  Last changed Sep 09, 2006

In this tutorial I will teach you how to add a bomb site to your first map and also how to make the bomb trigger and explosion.

For this tutorial I will be using the same map from this tutorial.

The completed map can be downloaded from here.

Creating the Bombsite

In the Texture Browser, filter for "toolstrigger" and select the texture.

Using the brush tool, create a box in the center of the map and click enter. This box defines where the bombsite will be. We use the Trigger texture because it will become transparent in the 3D view port.

Right click the newly created box and click "Tie to Entity". From the drop down list, select "func_bomb_target". Click apply and the bombsite is done.

Exploding Objects

You have the bombsite made and the bomb will work, but  how about making something explode when the bomb does? Lets start small with some crates.

Open the Texture Browser and filter for "crate", select a wooden one that you like. Using the brush tool, create a 64x64x64 cube and place it inside of the bombsite. Once the crate is created, you will find that the texture does not fit it correctly. With the crate selected, click the texture application tool. In the window that pops up, click "Fit" and the crate should now look normal.

Copy and paste the crate a few times and move them around so it looks appropriate.

Select all of the crates and "Right Click > Tie to Entity". From the drop down menu choose "func_breakable". We will need to change several of its properties so that it works right.

Name: crates

Strength: 0

Material Type: wood

Now go to the "Flags" tab at the top, and check "Only Break on Trigger" this will make it so that the crate will not break when shot.

Now we need to edit the func_bomb_target's properties so that it triggers the func_breakable. Right click the func_bomb_target and go to properties. Click the tab named "Outputs". Click "Add" near the bottom and use the follow settings:

My output named: BombExplode

Targets entities named: crates

Via this input: Break

Target Decal

We are almost done. We have a bombsite and crates, we just need to place a target decal on the ground so that players will know were the bombsite is.

Open the Texture Browser and filter for "{target" pick one of them. Now we will need to use the decal application tool. The button is on the left toolbar and looks like this:

All you need to do now is click on the ground near the bombsite and the decal will appear.
