This first part is for those who has not set up their computer yet for making mods or that you might have not set up Unity correctly.

Remember to take note of the Unity version that it should be 5.4.x

(Please note the first video is outdated, I will eventually replace it with a newer video)

• Unity - https://unity3d.com/get-unity/download/archive (version 5.4.0)
  
• Unturned

The unityPackage examples are a great sample reference for any particular workshop content that you are working on.



The default directory for the examples folder are as follows:
Windows
Mac


1) First open Unity and select the project that you have set up for creating the assetBundles. If you have not set up Unity yet, check out Part 1 of the tutorial video above in this guide


2) After the project window opens, either right click in the Assets tab directory to open up the Import Package window or drag-drop the unityPackage directly into the window
3) Make sure all the objects are selected/ticked before pressing the Import button

The example from this unityPackage that will be taken reference from will be this Yellow Hatchback. Either drag the Vehicle prefab into the Hierarchy window or the Scene window.

The recommended model file format for Unity is the fbx format. For better organization, I created a Models folder in the Assets directory for a place to store the models.

To import the fbx file, either right click the window space in the Projects tab to Import New Asset or drag drop into the directory directly

One thing worth checking on the imported fbx is the Scale Factor. You can either change the size of the model from the Scale value in Transform attribute or changing the multiplier in the Scale Factor. If changed in the Import Settings, remember to press Apply at the bottom of the Inspector.

Create a new folder in and name the folder based on what vehicle you are creating, here are some examples of my folder names:


For this tutorial I am working on a 6x6 offroader, and the following image shows the contents in the folder and what are each of its purpose:
(don't worry if you haven't got these stuff done yet I am just trying to explain the contents first)


My personal favourite approach to making Unturned assets is modifying existing prefabs instead of creating them from scratch and adding the components. Either approach is fine when it comes to creating them.

For this tutorial I will be making use of the Vehicle prefab that has been dragged into the scene to modify it to the vehicle that I am working on.

To apply a prefab, simply drag the Vehicle gameObject into their corresponding folder. It will apply any changes you made.

To update the prefab, delete the older version of the prefab from the Project folder while there is still a copy in the Hierachy and drag in the new one to overwrite. The name of the gameObject in the Hierarchy will turn from blue to red upon deleting as it breaks the link from the old version and it will turn back to blue after applying the prefab again.

The sequence of the gameObjects in the prefab does not matter as long as it is parented correctly, but the following will be the sequence that this guide will be going through. The details for each of the gameObjects will have a table for what they contain and what to take note of when editing the gameObjects.

Vehicle is the main part of the prefab.




(Refer to 3.15 LOD Group)

Components give GameObjects functionality. For this section we will go through what components are involved and how do we apply them to which gameObjects
