Getting Game Attack Animations Right with AI Prompts

Idle and walk animations come out well from presets alone — they're repetitive, in-place motions that leave the AI little room to misinterpret. Attack motions are different. Which hand, which direction, what timing — these are gameplay-critical, and with a vague prompt the AI will swing the wrong way or throw a punch straight at the camera. This post covers how to prompt attack motions so they come out as intended.

Write the three beats of an attack into the prompt

A good attack animation has three beats: anticipation (pull back), strike (snap forward), recovery (return to stance). Write that structure into the prompt verbatim. "The character swings a sword" is worse than "the character pulls the sword back to charge, swings in one quick motion, then returns to the original stance." Ending with "returns to the original stance" makes the result loop cleanly and chain into an idle.

Specify direction in screen space, not character space

The most common failure is direction. Write "attacks with the right hand" and the AI can't tell if you mean the character's right or the screen's right. For a side-view game, use screen space: "extends a horizontal punch toward the left side of the screen, then retracts." One more thing: AI models love staging action toward the camera, which ruins side-view sprites. Add explicit negative directions — "does not punch toward the camera," "stays in side view."

Margin and position: leave room in the attack direction

Arms and weapons reach far beyond the character's body during an attack. Set a generous margin in the generation options, and use the position setting to leave space on the attack side — attacking left? Place the character toward the right of the frame. Skip this and the weapon tip clips out of frame at the exact moment that matters most.

Extract frames with the "Distinct" strategy

Unlike walking, attacks are uneven: a long wind-up, then a split-second strike. Evenly-timed frame extraction misses the strike, so use the "Distinct" strategy, which favors frames with the biggest pose differences. The motion-intensity graph shows the strike as a peak — check that frame made it in, and click its thumbnail to add it manually if not.

Make the hit reaction as a pair

If you made an attack, make the hit reaction too — in an action game they're a pair. The hit preset (a flinch knocked backward) is one click. From the same character image, generate idle, walk, attack, and hit and you have the basic set a combat prototype needs.

Get started

Try it in the GenioPlus animation tool with one image of your character. Start with the slash preset to get a feel, then write your own prompt using the tips above. Free credits cover plenty of experimentation.
