Creating a 3D Character Animation for Walking in Unity

Walking is one of the most basic actions that a human can perform, and it’s also an essential action for any character to perform. In this guide, we will walk you through the process of creating a 3D character animation for walking in Unity. We will cover everything from setting up the scene to rigging and animating the character.

Setting Up the Scene

The first step in creating a 3D character animation is to set up the scene. This involves creating the environment, adding objects, and positioning the camera. For this example, we will create a simple scene with a single character and a background.

  1. Create a new Unity project and select “3D Object” as the template.
  2. In the Hierarchy view, right-click and select “GameObject.” Choose “3D Object” and name it “Character.”
  3. Select the Character object and go to the Inspector window. Add a Rigidbody component and set its Gravity Scale to (0, -9.81, 0).
  4. Add a Box Collider component to the Character object and adjust its size and position as needed.
  5. In the Hierarchy view, right-click and select “GameObject.” Choose “3D Object” and name it “Background.”
  6. Select the Background object and go to the Texture 2D window. Add a texture image for the background.
  7. Position the Camera object and adjust its field of view as needed.

Rigging the Character

The next step is to rig the character. Rigging involves creating a skeleton for the character and assigning animations to it. Unity provides a built-in tool for rigging called the “Animator.”

  1. Select the Character object in the Hierarchy view.
  2. Go to the Animation window and click on the “Create” button.
  3. In the “Create Animator Controller” dialog box, select “2D” as the type and click “Next.”
  4. Name the animator controller “WalkingAnim” and click “Create.”
  5. In the Hierarchy view, right-click and select “GameObject.” Choose “3D Object” and name it “Armature.”
  6. Select the Armature object and go to the Animation window. Click on the “Import Animation” button and choose the animation files for your character.
  7. Drag the animator controller onto the Armature object in the Hierarchy view.
  8. In the Animator window, click on the “Create” button and select “Animation Clip.” Name it “WalkingAnimation” and click “Next.”
  9. In the “Create Animation Clip” dialog box, select the animations you want to include in the walking animation and click “Create.”
  10. Drag the WalkingAnimation clip onto the armature object in the Hierarchy view.

Animating the Character

The final step is to animate the character. Animating involves setting keyframes for the character’s movement and applying them to the animations.

  1. Select the Armature object in the Hierarchy view.
  2. Go to the Animation window and select the WalkingAnimation clip.
  3. Set the playback speed to a comfortable walking speed (e.g., 1.5).
  4. In the “Animator” tab, set the “WalkingAnimation” as the default animation.
  5. Select the Character object in the Hierarchy view.
  6. Go to the Animation window and select the WalkingAnimation clip.
  7. Set the playback speed to a comfortable walking speed (e.g., 1.5).
