Getting Started: Radiant Level Editor for COD Zombies

By Frosty_Mango

Looking to make maps for Call of Duty: Black Ops 3 Zombies map in 2025 and have no clue where to start? Through my own experience getting to know the editor I have created this guide based off my own resource document to provide useful information such as links to Radiant documentation and YouTube tutorials that will get your map off the ground.

I plan on updating/editing the guide as time goes on but that will depend on whether or not I will have the time to do so. Hope this helps!

All constructive feedback is welcome.

Creating Your First Buyable Door

Overview

In addition to the YouTube Tutorial posted previously, here is my step by step process on how to create a buyable door that swings (rotates) open when you purchase it.

GETTING AND PREPPING THE DOOR MODEL

Hit B on your keyboard to open the Entity Browser window, find and click on Script then select Model in the drop down.

Pro tip: Right click the Script label in the Entity Browser then click "toggle favorite" to be able to right click in Camera window to pull up a menu to place any object from the Script category or any favorited categories.
You will then see a red cube in the Camera window once the script_model is placed.
Select the red cube then hit M to bring up the Models Window and find any door model you like! Then with the script_model (the previously red cube) selected double click on any model you like in the Model Window to set the model!
With the script_model selected and go to the Entity Info Window via the N key.
Then select the Value next to the Property, target_name and input "zombie_[insert door name]". In order for this name to be referenced properly later, the Value MUST have the prefix "zombie_" to it as shown in the image below.
Next you will need to add some KVPs (Key-Value-Pair). You can do this by navigating to the bottom right of the Entity_Info window to click the Add KVP button.
Then input the Property / Key and Value as seen below.

Property/Key

Value

script_angles

0 0 0 (for now)

script_flag

enter_zonename

script_string

rotate
Now that you have the KVPs looking similar to the image above, find the angle you want your door to move to by navigating to the top of the Entity Info window to find the Property, angles.
Once there adjust the middle value (which should be 0) to find the amount of degrees you want your door to rotate. Once you found your perfect amount of degrees input that number back into your script_angles KVP. As seen in the image the value I put in was 120.

ADDING COLLISIONS AND ENABLING "BUY DOOR" PROMPT

To start we'll be adding collisions to the Door model by adding a script_brushmodel with the Clip texture. The Clip texture enables collision with players, enemies, and NPCs.

Right click in the Camera Window next to your door model. Go down to the bottom of the drop down to find script_brushmodel and select it.
Then hit the T key to bring up the Textures Window and select Clip (it should be a red color with the word clip on it).
With your script_brushmodel created and possessing the Clip texture, in the Entity Info set the target_name Property to the same Value you gave the Door model.

In my case the Value was zombie_door_1
The last step for this object is adding a KVP as seen in the image above.

Property = script_noteworthy
Value = clip

This can also be viewed in your installed files on your computer. They should be at this location (if installed on your base hard drive)! There are lots of other useful files there as well.

YouTube links in the guide should be fixed now. A weird formatting error from Steam broke all the links :p. Feel free to comment if they are not actually fixed and I will do my best to fix it up.
