Unity Basics Course: Hit and Death State Animation

In this tutorial, we will learn how to implement the hit and death state animations for game characters using the Unity engine. The state changes of characters in a game are very important, and this process can greatly enhance the player’s experience.

1. Basic Preparation

Before starting a Unity project, a few basic settings are required.

1.1 Installing Unity

Download and install the latest version of Unity. After installation, create a new 3D or 2D project.

1.2 Preparing Animation Resources

Prepare animations to be used for the game character. You will need hit animations and death animations. Animations can be created using 3D modeling tools like Blender or purchased from animation marketplaces.

2. Setting Up Character Animations

Create an animator controller for the character to set up hit and death state animations.

2.1 Creating an Animator Controller

Select the character in the Hierarchy view and add an Animator component. Open the Animator window and create a new animator controller.

2.2 Adding Animation States

In the Animator window, add the hit animation and death animation as states. I will explain how to define and transition between these two states.

3. Transitioning Between Hit and Death Animations

Let’s learn how to change the state and transition the animation when the character is hit.

3.1 Creating a Script

Select the character in the Hierarchy view and create a C# script. Name the script CharacterHealth.cs. Below is an example of the basic code:

using UnityEngine;

    public class CharacterHealth : MonoBehaviour
    {
        public Animator animator;
        public int health = 100;

        public void TakeDamage(int damage)
        {
            health -= damage;

            if (health <= 0)
            {
                Die();
            }
            else
            {
                animator.SetTrigger("Hit");
            }
        }

        private void Die()
        {
            animator.SetTrigger("Die");
            // Additional death logic here
        }
    }

3.2 Setting Up Animation Triggers

Return to the Animator window to set up state transitions. Create Hit and Die triggers. Set the transition to change states based on the Hit trigger during the hit state. Use the Die trigger to modify the animation during the death state.

4. Handling Events and Adding Hit Effects

Add effects when hit to enhance the immersion of the game. I will explain how to add hit effects and sound effects.

4.1 Adding Hit Effects

To increase sensitivity with specific effects, use Unity’s Particle System. Activate effects to display them when the character is hit.

4.2 Adding Sound Effects

Sound effects for hits and death have a significant impact on player feedback. Add an audio source and link hit and death sounds.

5. Optimization and Testing

Finally, test whether the animations and scripts are functioning properly. Optimize to improve game performance and fix bugs.

5.1 Debugging

Use Debug.Log() to output the current state to ensure the script is working correctly.

5.2 Testing Animations

Play the game and check if the character’s hit and death animations work correctly. Adjust the length or speed of the animations if necessary.

Conclusion

Through this tutorial, you learned how to implement hit and death state animations in Unity. These elements are very important for enhancing the immersion of the game. Practice to understand each element more deeply and create your own unique game.

Good luck!
