Basic - Normal Weapon Mod

Here is a step by step tutorial for making a weapon mod.

Phase 1: Define your mod#

1. New mod project#

Make sure you have the prerequirements for modding and download a fresh ModToolkit to start.

2. Remove unused content#

Make sure to remove the demo content so that we have a clean project to start with.

  • In the Unity toolbar; click Tools > Destructive > Cleanup All Content.

3. Product name#

Change the product name so that the mod folder name will not conflict with other mods.

  • In the Unity Toolbar: Go to Edit -> Project Settings -> Player.
  • Modify field Product Name to your new mod name. Use the format: YOURPREFIX_MyModName. Example: WMD_ChevalierWeapons

4. Prefix.#

Change the project prefix so that the mod files will not conflict with other mods.

  • In the Unity file browser: Open Assets -> Resources -> AddressableConfig.asset

  • Modify field Prefix to your new prefix name. Use the format: YOURPREFIX_MyModName_. Example: WMD_ChevalierWeapons_

    Note: The prefix used in the tutorial is WMD_. You will need to fill in your new prefix instead of every WMD_ in the tutorial.

5.Generate folder structure using the template wizard.#

  • In the Unity Toolbar: Go to Tools -> Template Wizard.
  • Make sure the inspector window is shown (Template Wizard will show there).
  • Enter a new mod folder name. Example: YourModName
  • Set the Mod Type to: Weapon.
  • Fill in the desired ItemInfoConfig fields.
  • Click the Generate Template button to generate the Weapon folder structure.

6.Place the model#

  • Open the newly created prefab in the Weapon folder. image
  • Drag your model of the sword into the prefab hierarchy under the parent object.
    Explanation: Parent object is the top object of the prefab. It will be called the same as the name of your prefab.
    (Example: Prefab file is calledNewModFolderName.prefab. parent object will be called NewModFolderName).
  • Rotate the model and resize the weapon until it feels ok in comparison to the dummy weapon. image
  • Under InteractWeapon, click show example weapon again to disable it.
  • Reference the MeshRenderer from the model to Skill Change Colors. (quick tips: if you want to place multiple renderer at the same time, you can click the lock button to lock the inspector, then drag them all at once) (the Skill Change Colors will be used for change weapon color when it's needed, such as damaged).

7.Add Collider for colliding#

  • Click Add Component to add Mesh Collider.
  • select Convex and change default layer to Interact layer. (quick tips: if you want accurate collision, we recommend Collider Creator in the unity asset store, but it's not free.) image

8. Define HitInfo and CollisionEffect#

In short, RagdollHitInfoObj defines how a collider deals damage and CollisionEffect defines what's the collision physics material is.

  • Change the values in RagdollHitInfoObj and CollisionEffect as (shown in screenshot) on the Parent Object. (Possible options to enter here are can be found on this page: HitInfo and CollisionEffect.) image
  • Then add these components(RagdollHitInfoObj and CollisionEffect) to the handle as well to distinguish hits between blade and handle. image (Explanation: To learn more about RagdollHitInfoObj and CollisionEffect, please read HitInfo and CollisionEffect.)

9.Add AttachLine for grabbing#

  • Drag AttachLine from the path Asset/Prefabs to the Parent Object.
    Explanation: AttachLine describes how your hand grabbing it. If you toggle Gizmos in the scene editor, then you will see a blue line where your hand will attach to.
  • Adjust the size of the Line Start Point and the Line End Point to modify the grab area.

Since this is a two-handed weapon, so we add another one:

  • Add another AttachLine, and this one should depend on the previous one.
  • Set DependAttachObj to the other.
  • Set Index Limit to Both, so that this attach will limit to player's hand in two direction of your index finger. image
  • At last, reference these AttachLines to the InteractWeapon component from the Parent Object. And select Allow Second Hand.

10.Add MountPoint for backpack#

MountPoint will determine where it will mount to your inventory slots like belt or back.

  • A MountPoint is already added for you by the template wizard (named MountAttach).
  • Move it to the relative position where it should attach to the backpack. image

11.Add StabObject for stabbing#

  • Add StabObject to Parent Object.
  • Define the StabArea to surround the blade. (Tips: you can hover the mouse over the parameter to view the tips.) image

12.Change weapon handling#

  • Click the Swing Like Hammer button. (it'll modify the grab force and hand speed) image
  • Save the prefab.

Phase 2: Prepare to export your mod#

Generating the icon

  • In the Unity Toolbar: Go to Tools -> Icon Generator.
  • Drag the Prefab of your mod (the weapon, avatar, scene) into the field: Game Object To Render.
  • Adjust the settings of the icon to your liking.
  • Click the Save PNG... button.
  • Overwrite the dummy icon in folder ICon of your mod that has been created for you previously. (keep the name as is. Don't change this).
  • Set the Max size to 256 and click Apply to save (yes screenshot shows 128, my bad).

Phase 3: Build the mod#

1. Update all addressables.#

  • Go to AddressableConfig(Assets > Resources > AddressableConfig) or use shortcut: ctrl+shift+e.
  • Click Clear Addressables and Create And Refresh Addressable Name.

Then you will see this tool has already setup addressable path for you in the Addressables Groups window. (Window/Asset Management/Addressables/Groups to open this window)

3. Build#

Click BuildTools > BuildAllBundles to Build.

Once you build it successfully, then you will find your mod in the Assets/Mods. If something errors, please checkout the Console information, unity will tell you what's going wrong. And feel free to ask questions on our discord server.

Phase 4: Test & publish the mod#
