Adding Enemy AI to Your Game

A world full of enemies that just stand there is a diorama, not a game. Enemy AI — even simple behavior — is what makes them feel like threats: patrolling their area, noticing the player, giving chase, and attacking. You don't need anything fancy to make enemies feel alive.

Start simple: states

Most enemy behavior is a handful of states the enemy switches between:

• Idle / patrol — wandering or walking a set path while unaware of the player.
• Chase — the player got close, so pursue them.
• Attack — in range, so strike.
• Return / give up — lost the player, so head back.

This simple loop — patrol → spot → chase → attack → lose → return — already reads as intelligent behavior.

Step 1 — Bring in an animated enemy

Import an enemy with its animations (idle, walk, attack, hurt). AI drives which animation plays, so the enemy needs the set first — the same core-action-set approach as the player.

Step 2 — Give it a patrol

Start with movement while unaware: pacing back and forth, wandering a small area, or following a path. This makes the enemy feel like it inhabits the world rather than waiting for the player.

Step 3 — Add awareness and chase

Give the enemy a detection range. When the player enters it, switch to chase — move toward them and play the run animation. When the player escapes the range, give up and return. That transition is the core of the illusion.

Step 4 — Attack in range

Once close enough, switch to the attack state, play the attack animation, and time the damage to the contact frame (pair with combat SFX for punch). Then recover and re-evaluate.

Step 5 — Sync animation and tune

Always match the animation to the state — patrol/idle, run when chasing, attack when striking. Then tune ranges and speeds: too aggressive is unfair, too passive is boring. Playtest until the enemies feel like a fair, fun threat.

Vary your enemies

Reuse this behavior with different stats and art — a fast weak swarmer, a slow heavy bruiser — for variety from one simple AI. Palette swaps make instant visual variants.
