Implementing the Palette

In this section, we will get hands on with the implementation of the Palette. Just to maintain a certain level of abstraction, in some cases, we will talk about Palette items instead level piece prefabs.

For us, a Palette item is what is displayed in the Palette, and this can be anything; in this case, a level piece prefab.

Creating a category system

We need some data to make the Palette window functional. The first step is to categorize the available level piece prefabs in the game. In Run & Jump, all the level piece prefabs are located in Prefabs/LevelPieces:

We will create a script with a mission to save information about the level piece prefabs, which includes the category. Inside the Tools/LevelCreator/Scripts folder, create a script called PaletteItem.cs with the following code:

using UnityEngine;

namespace RunAndJump.LevelCreator {
  public class PaletteItem: MonoBehaviour {
    #if UNITY_EDITOR
        public enum Category {
            Misc,
           ...
