Prepare the Mod and Extract Files

Download the Mod:
Ensure you have subscribed to the NPC Mod on Steam Workshop. (The One You Want To Either Edit For Personal use & or learn from)
Locate the mod files in your Unturned workshop directory, typically found in Steam\steamapps\workshop\content\304930\<mod_id>. (GO TO MANAGE MODS IN UNTURNED AND CLICK BROWSE FILES)

Extract Mod Files:
Copy the entire mod folder to a location where you can edit the files (e.g., your Unity project or a separate folder).

Locate and Copy NPC Files

Identify NPC Files:
In the mod folder, look for .dat files related to NPCs, typically found in folders named NPCs, Quests, or Vendors.

Copy NPC Files:
Copy the .dat files you want to use as a base. For example, if you want to use NPC_001.dat, copy this file and rename it to something unique, such as MyCustomNPC_001.dat.

Edit NPC Files

Edit NPC Data:

Open your copied .dat file in a text editor.

Change the ID to a unique number that does not conflict with other IDs.

Modify the Name, Dialogue, and any other properties to suit your needs.

Example:

plaintext

Name MyCustomNPC
ID 5001
Dialogue
{
Text "Hello, survivor! Need any help?"
Responses
{
1 "Sure, what can I do?"
2 "Not now, thanks."
}
}

Create or Edit Quest and Vendor Files

Has_Killed_Animals 5
