Over the past 4 months, my team and I have been working on a rogue-like hack-and-slash game for our school’s final year project called Dust to Dust. We have very high ambitions for the game, and we had never worked on projects as large of a scale as this. Of course, by doing that, the challenges we encountered got bigger as well. We had to keep track of many parameters in developing a role-playing video game, and quickly realised that the time taken to find Inspector properties in the project was getting longer and longer. Furthermore, the project was on a 15-week timeline, so every minute was valuable.

Hence, we needed an effective solution that would ease navigation in the project, and — like before — it became clear that we had to once again extend the Unity Editor to suit our needs.

Over the last 5 months or so, me and my team have been involved in the development of a hybrid tower defense and RTS game called Ex-Terminator (click on the link to try it out, it’s free!) as part of a school project. During the course of developing the game, we quickly realised that, in order to allow us to have the flexibility to experiment with our level design, we had to experiment with a class in Unity called the ReorderableList.

If you’ve read some of the other articles here, you’d have noticed that we normally link Unity classes to its page on the Unity Scripting Reference. We didn’t do so here because there is no official documentation for it at the time this article was written. The ReorderableList class is filed under the namespace of UnityEditorInternal, which also doesn’t have official documentation. We’ve decided to write an article about it, however, because of how useful it is, and because of how little information there is currently about it online.

In any given game, you are probably going to find dozens, if not hundreds of different objects colliding or intersecting with one another. Hence, one of the first things you learn in Unity is how to identify the type of object you have touched. These are the most common ways to do so among beginners:

void OnTriggerEnter(Collider other) {
     // If a GameObject has an "Enemy" tag, remove him. 
    if(other.tag == "Enemy") {
        Destroy(other.gameObject);
    }
}

void OnCollisionEnter(Collision collisionData) {
    // If a GameObject has an "Enemy" tag, remove him.
    if(collisionData.collider.tag == "Enemy") {
        Destroy(other.gameObject);
    }
} 

Essentially, the idea is checking whether the object we are colliding with or touching has been labelled with an Enemy tag, before we perform any action on the object.

While it is simple and easy-to-understand, there are better ways of identifying objects we are colliding with.
