Enemy Components and Behaviors

In the last chapter, we were introduced to the types of enemy AI and how each type operates depending on which state it is in.

In this chapter, we will learn in detail how to use and change the enemy behavior by understanding its components and variables. Then, we are going to use this information to play around and twist some values in order to get the enemy behavior closer to what our game requires.

The following topics will be covered in this chapter:

• Basic 2D enemies' components
• Basic 3D enemies' components

2D Game Kit enemies

Following on from our 2D game development experience, we need to understand the enemies in depth, their components and behaviors, and how to modify them.

In this section, we will focus on the following components of the chomper:

• Character Controller 2D
• Damageable
• Enemy behavior

In addition to this, we will learn about the following components of the spitter:

• Spitter BT

After that, we will take a look at the enemy spawner and how it works.

Chomper

The Chomper is the most common enemy of the game, and we will find that it is pretty simple in its AI. The behaviors behind this enemy can be seen by clicking on the Chomper prefab under Assets | 2DGamkit | Prefabs | Enemies, as shown in the following screenshot...

3D Game Kit enemies

Moving on to the next topic of the 3D game development experience, we will learn about our enemies in depth by understanding their components and behaviors, and the best way to modify their properties.

In this section, we will focus on the following components of the Chomper:

• Chomper Behavior
• Damageable
• Replace With Ragdoll
• Enemy Controller

Summary

Know your enemy. This was the main focus of this chapter, knowing our enemies.

The chapter was focused on learning about the behaviors of the chomper and the Spitter, what they can do, how they are able to see the player, when they will react, and so on. By knowing this information, we are going to be able to create different types of enemies, because we can duplicate the enemies' prefabs and change the values of their behaviors, which will finally end up in them having different behaviors.

This will enhance the challenge level of the our game, making our level more fun and challenging to play. We need to keep in mind that the player's attention and interest must be sustained at all time.

In the next chapter, we will face our demons by looking at the level boss, the most powerful enemy of all. We will look at how we can manage its power and use it to our advantage...
