Mortal Kombat (1992) filmed actors and digitized the footage into sprites. This does the same thing with a video model as the actor: one short clip per move, cut down to its pose extremes, chroma-keyed to transparency, and packed into an atlas you can drop into an engine. A character with eight moves costs about $5 and lands in an afternoon. What it covers - The character-still recipe: side view, planted feet, flat magenta backdrop, and the \"no grain, no dust, no vignette\" clause that keeps the chroma key clean. - The idle pin : setting a move clip's first and last frame to the same idle still, so the character cannot drift off-model, every animation returns to neutral, and moves chain in a state machine. - Clip briefs, including the guards that stop cartoon models ballooning fists on impact and the in-place (\"treadmill\") walk phrasing that keeps the engine in charge of movement. - Frame extraction, keying with a despill that does not tint the character, and keyframe selection by cumulative motion arc-length rather than uniform sampling. - Seamless walk-cycle detection, because whole-clip keyframes include the start-up and the settle back to idle, which is what makes a walk visibly reset instead of loop. - The atlas and rendering math: one global scale (never per-frame normalization), anchoring from the ankle centroid, and the drawImage offset that decides whether your character stands o","default_branch":null,"files":null,"tree":[],"storefront":"/r/gary149","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/gary149/h3-game-sprites/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
