Combine basegun
From HalfLife 2 Knowledge Base
It takes a bit more effort to make a working Combine basegun (aka Combine turret) then just placing the right model on the map. This tutorial explains how to create those Combine baseguns that you've encountered throughout Half-Life 2. Read on if you would like to have a working one on your own map. Note that this only works on single-player HL2 maps, not deathmatch or CS:S maps.

Placing Models
Begin by creating a simple room with an info_player_start entity. Now, make a platform for the gun to sit on: place a [[prop_static] entity right where you want the gun and use "models/props_combine/combine_barricade_short01a.mdl" as your model. Create a prop_dynamic entity right above the shield — this will be our turret. Set "models/props_combine/bunker_gun01.mdl" as your model. Name it "im_the_gun" or whatever your heart might fancy. Your should now have something like this:
Player Trigger
A player-sized brush is used to operate the weapon. Create a trigger brush, around 32x32x72 units in size. Place it behind the Combine shield, right next to the back end of the gun. Name the entity "gun_control":
Gun Trigger
A special brush is used to configure gun's functionality. Create a small box with the trigger or nodraw texture. Set height to 4, width to 4, and length to 22. Name it "im_the_barrel". Location of this brush apparently does not matter, but under the barrel seems like a perfect place for it:
Settings
Go to properties of "im_the_barrel" and set its class to be func_tank. For our example, set the option values as follows:
| Properties: | |
| Name: | "im_the_barrel" |
| Control Volume: | "gun_control" |
| Yaw Rate: | 200 |
| Yaw Range: | 60 |
| Yaw Tolerance: | 15 |
| Pitch Rate: | 120 |
| Pitch Range: | 60 |
| Pitch Tolerance: | 15 |
| Barrel Length: | 31 |
| Barrel Horizontal: | 8 |
| Flash Sprite: | "materials/sprites/ar2_muzzle1.vmt" |
| Rate of Fire: | 26 |
| Damage Per Bullet: | 20 |
| Damage Per Bullet Vs player: | 5 |
| Bullet Accuracy: | Small Cone |
| Maximum target range: | 2048 |
| Gun Base Attachment: | aimrotation |
| Gun Barrel Attachment: | muzzle |
| Gun Yaw Pose Param: | aim_yaw |
| Gun Pitch Pose Param: | aim_pitch |
| Gun Pitch Pose Center: | 7.5 |
| Effect Handling: | AR2 |
| Bullets: | AR2 |
| Flags: | |
| Controllable | Checked |
The names of most options are pretty much self-explanatory; feel free to experiment with things like rate of fire and effect handling. For more information about various options, see func_tank.
Final Product
This is what we end up with: a working, perfectly animated working gun. Try it: press Use, aim and fire!
