Modular animation, where a character is built from separate body parts like arms, legs, and heads, is a popular technique for 2D game characters. While it offers flexibility and reusability, proper setup and optimization are key to achieving smooth, professional-looking animations.
Modular animation saves time, memory, and allows for dynamic character customization, but requires careful organization and pivot placement.
Each body part should have its pivot point at the joint or rotation point (e.g., shoulder for arms, hip for legs). Consistent pivots ensure that swapping sprites or animating limbs doesn’t break the character’s structure.
When rotating or scaling parts, small gaps can appear at joints. Adding a few transparent pixels around the joint area helps prevent visible seams during animations.

Combine modular animation for main movement with frame-by-frame effects like weapon swings, particle effects, or blinking eyes to add more expressiveness.
Decide your target resolution before creating parts. For example, if characters are 128px tall in-game, design parts slightly larger to allow downscaling without losing detail. Avoid creating extremely large parts unnecessarily, as they waste memory.
By following these tips, you can make modular 2D character animation efficient, flexible, and visually appealing. Proper pivots, padding, organized files, and smart use of sprite sheets will make your workflow faster and your animations smoother.
