2D Chasing Enemy AI – Platformer Follower with Smooth Animation & VFX

2D Chasing Enemy AI – Platformer Follower with Smooth Animation & VFX

This asset provides a fully animated 2D flying enemy AI designed for Unity platformer games. It includes intelligent auto-chasing behavior, allowing the enemy to follow the player once they enter a defined detection radius.

When idle, the enemy remains airborne and hovers in place. Once the player is detected, it begins moving smoothly toward them, flipping left or right depending on the player's position.

This system features a complete kill mechanic. If the player jumps on the enemy’s head, the enemy is destroyed with a death sound, a particle effect, and a bounce effect that propels the player upward. On the other hand, if the player touches the enemy’s body, it will damage or kill the player, depending on your game logic. These interactions are managed through two separate colliders: one on the head (for stomping and killing the enemy), and one on the body (for player collision/damage).

The asset is lightweight, clean, and ideal for Unity developers looking to add a responsive, visually polished, and script-ready enemy to their 2D game. All code is fully written in commented C#, and everything is ready for use in both URP and Built-in Render Pipelines.
