Sprite Auto Walker

AI finds the hips, knees and ankles, rigs the legs and walks your sprite — live.

Turn one standing sprite into a walk cycle

Side-view sprites with visible legs and a transparent background work best.

Leg Paint Squeeze

Blue and pink can only ever sit on the character itself, inside the dashed leg box — never on empty space. If a colour still covers too much, pull it in from its side until it hugs just the leg. It snaps to the outline of the art.

Leg Separator

For legs that touch or press together. Finds the hidden valley between them and cuts a hair-thin gap that follows every curve.

1Step 1: Distance TransformMaps how deep every pixel sits inside the legs to find each leg's centre-line
2Step 2: Watershed TopologyFloods out from both centre-lines; where they meet is the valley between the legs
3Step 3: Micro-Erase MaskingErases a hair-thin line exactly down that valley
4Edge clean-up: SDF anti-aliasingIsolates the cut, softens it with a sub-pixel blur and blends it back, so no jagged steps
