Idle Animation

Animation: Bringing Your Character to Life

We've added sprites to our game, but when we press Play, the player character still feels frozen and lifeless. That's because there’s no animation yet. Animation is what gives characters energy and personality.

Even when a character is standing still, there's usually some subtle movement: breathing, blinking, or shifting weight. This is known as an Idle animation.

Animation itself is an illusion of movement, created by rapidly switching between slightly different images, called frames.

Designing an Idle Animation

To create an idle animation, we make small variations of the same character sprite. These changes don't need to be dramatic, subtle movement goes a long way.

Examples of small variations include:

• Eyes opening and closing;
• Slight changes in leg or torso position;
• Minor movement in clothing or accessories.

These frames can be created using image editors like Photopea or Piskel.

Bringing Animation Frames Into Unity

There are two common ways to import animation frames into Unity:

• Separate images: export each frame as its own .png file, import them into Unity, select them all, and drag them into the Scene. Unity will automatically create an animation for you;
• Sprite sheet: place all frames into a single image file. In the Inspector, change the Sprite Mode to Multiple, open the Sprite Editor, slice the image into individual frames, and apply the changes. You can then use these frames to create an animation.

Refining the Animation

Sometimes the animation works but feels chaotic or unnatural. This usually happens when frames are out of order or when there are too many of them.

You can fix this using the Animation window, where you can:

• Reorder frames;
• Duplicate or remove frames;
• Preview the animation in real time.

Setting Up the Animator

To properly control the animation, the player character uses an Animator component. By assigning the animation's Animator Controller to the player object and removing any temporary animation objects, the setup stays clean and manageable.

With an idle animation in place, your character now feels alive, even before we add movement or gameplay logic. This small step makes a huge difference and sets the foundation for future animations.
