Building a Character Controller in the Game Engine

You've generated a character and animated it. A character controller is what turns that art into something the player actually drives — reading input, moving the sprite, facing the right direction, and playing the right animation for what it's doing. This is the heart of a playable game.

What a controller does

Three jobs, working together:

1. Read input — arrow keys, WASD, a gamepad or touch.
2. Move the character — translate that input into motion in the world.
3. Play the matching animation — idle when still, run when moving, and face the direction of travel.

Get these three in sync and your character feels alive instead of sliding around.

Step 1 — Bring in your animated character

Import your sprite sheet and set up its animations (idle, run, and directional facings). The controller is only as good as the animation set behind it — build the core set first.

Step 2 — Wire up movement

Map input to motion: pressing left moves and faces left, and so on. Keep the mapping predictable — players expect direction keys to do exactly what they say.

Step 3 — Sync animation to state

This is what sells it. The character's animation should always match what it's doing:

• Not moving → idle.
• Moving → run/walk, flipped or swapped to the correct facing.
• Acting → attack/jump one-shots, then back to idle.

Switching cleanly between these states is the difference between a puppet and a character.

Step 4 — Tune the feel

Small tweaks to speed and responsiveness change everything. A controller that responds instantly feels tight; a laggy one feels mushy. Adjust until movement feels good to you — feel is a real design decision, not an afterthought.

Where it leads

Once the player moves and animates correctly, you've got the foundation for everything else — a tilemap level to move through, enemies to fight, and items to pick up.
