In a game, players, enemies, and obstacles are bound to hit each other at some point. When that happens, a collider is necessary to handle these events. A collider detects collisions between GameObjects. The Collision class holds specific information about the collision that can be sent to the Collider class and used in specific cases…
If you are using a GameObject that needs to interact with Unity’s physics engine, then you need a Rigidbody component added to it. A Rigidbody component allows you to control a GameObject‘s position and movement and mass through realistic physics calculations already built in Unity. There are many properties and functions associated with Rigidbodys, and…
When you play a game with an endless number of the same enemies attacking you, how do you think that works? Did the developer make each of those enemies separately? Or did they use something like a prefab in Unity? A prefab is a specific GameObject that can be reused as many times as needed…

In a previous article, we showed how you can move a platform in Unity by using the function MoveTowards() and the function Mathf.PingPong(). You can find that article here. Another way to move a platform is to us an animation. This allows you to have some more complex movements fairly easily. Create an animation for…
If you think about it, I’m sure almost every game you have played has had projectiles in it. They are an integral part of many games. Unity makes it fairly easy to fire a projectile. These are the basic steps to fire a projectile in Unity: Create Your Game Objects This will be a simple…
There are many reasons why you would want to destroy a gameobject in your app. Depending on the situation, you can use a specific function to make this happen, such as OnCollisionEnter(). To destroy a gameobject on collision, use the OnCollisionEnter() function for the collision itself and the Destroy() function to destroy a gameobject when…
