A Sixteen-Frame Pixel Spell Sprite Sheet — AI Image Prompt Guide

Plan a spell animation through charging, release and loop phases, using a fixed baseline and grid to guide consistency across sixteen pixel-art frames.

English translation of the public case notes.

Create a looping chibi pixel-art spell-casting sprite sheet from a written character description. The deliverable is sixteen frames in a 4×4 layout with a transparent background, suitable for game animation and character effects. Describe the character first, then pixel style, the action timeline, cell dimensions, frame order, padding and alpha transparency. The movement should progress through charging, releasing the spell, recoil, fading effects and a return to the starting pose. Keep the viewpoint, character scale and baseline fixed. Preserve recognisable features and prevent shifting proportions, overlapping cells, cropped effects, text, watermarks and grid lines. Avoid blurred pixel edges, smooth vector rendering and photorealism. The source also requests a transparent 16px margin, but its final delivery instruction is incomplete. [Source text is truncated.]

👀 这次试试｜16帧像素能量波模板对照模式：图像案例。结果比预想更值得看：这个案例重点在把角色设定、像素风、动画节奏和精灵表规格写进同一条提示词。适合做游戏角色待机/施法素材，也适合学习如何约束透明背景、帧序、基线和循环衔接。变量拆解：类型：文生图输入：一个角色外观描述，以及像素风、16帧动作、4×4精灵表、透明背景和交付格式要求目标：得到可循环的Q版像素施法动画精灵表，并尽量保持角色识别度、帧间一致性和透明边界关键词：Q版角色 / 像素精灵 / 16帧循环 / 能量爆发 / 4×4精灵表 / 透明背景 / 固定基线重点：先定义角色识别特征，再限定像素风，随后写动作时间线，最后用单元格尺寸、排序、留白和透明度锁定输出结构约束：避免模糊边缘、矢量平滑感、写实渲染、角色漂移、帧间比例变化、单元格重叠、网格线、文字、水印、背景伪影和裁切 💡 复现实验的三把钥匙 • 把动作拆成“蓄力—释放—后坐—淡出—回环”，比只写“施法动画”更容易得到可用帧序 • 用“固定基线、固定视角、固定尺度”约束帧间一致性，适合游戏资产管线 • 透明背景和16像素安全边距写得很明确，可减少后… #GPTImage2 #OpenAI #AI绘画 #像素精灵 #Q版动画 #精灵表

Chinese prompt

将下面描述的角色变成一个可爱的像素艺术精灵，并带有循环的能量爆发施法动画。
角色
角色是漩涡鸣人：尖刺状金发、橙色和蓝色忍者连体服、脸颊上的胡须状纹路、带金属牌的额带。保留角色可识别的特征、颜色、发型/质感、服装、配饰和独特轮廓。将其原始解剖结构改编为可爱的 Q 版比例，但不要把非人类角色强行改成人类身体。
风格
创建清晰的像素艺术，具有明确的方形像素、干净的轮廓和统一的有限调色板。不要有模糊边缘、平滑矢量风格或写实渲染。
动画
创建 16 个连续帧，组成一个无缝循环的能量爆发施法动画：
角色抬起一只手或武器，聚集发光能量，并向外释放爆发。
能量粒子从小火花逐渐增长为完整爆发，然后在返回帧中淡出。
在释放帧有轻微后坐/后仰。
在所有帧中保持设计、比例、摄像机角度和尺度一致。
让角色固定在单元格内，除非动作描述需要小幅原地位移，否则不要偏离中心。
让最后一帧能够平滑过渡回第一帧，形成完美循环。
精灵表
将 16 帧准确排列为 4 列 × 4 行，按从左到右、从上到下的顺序排列。
画布：1024 × 1024 像素。每个单元格：256 × 256 像素。
在所有单元格中使用相同对齐方式和固定基线。
让整个角色都在每个单元格内，包括移动的配饰或特效周围，每一侧至少保留 16 像素透明留白。
不要有重叠单元格、网格线、标签、文字或水印。
透明度
使用真正透明的 RGBA 背景，角色以外区域的 alpha 为零。不要绘制棋盘格，也不要添加纯色背景、地面或投影。保留角色内部的白色和浅色细节。
交付物
一张透明的 4×4 PNG 精灵表。
一个透明的单角色动画 GIF，使用全部 16 帧，每帧 256×256 像素，无限循环，周期约 2.2 秒。
一个包含全部 16 张独立透明 PNG 帧的 ZIP。
如果需要调整尺寸，请使用最近邻采样以保持像素清晰。最终确认前，确保没有杂散像素、裁切或背景伪影，并且背景真正透明。

English prompt

Turn the character described below into an adorable pixel-art sprite with a looping energy blast cast animation.
CHARACTER
The character is Naruto Uzumaki: spiky blond hair, orange and blue ninja jumpsuit, whisker marks on cheeks, forehead headband with metal plate. Preserve the character's recognizable features, colors, hairstyle/texture, outfit, accessories, and distinctive silhouette. Adapt its original anatomy into cute chibi proportions without forcing non-human characters into a human body.
STYLE
Create crisp pixel art with clearly defined square pixels, clean outlines, and a cohesive limited palette. No blurry edges, smooth vector styling, or realistic rendering.
ANIMATION
Create 16 consecutive frames of one seamless energy blast cast animation:
Character raises a hand or weapon, channels glowing energy, and releases a burst outward.
Energy particles grow from a small spark to a full burst, then fade on the return frames.
Slight recoil/lean-back on the release frame.
Keep the design, proportions, camera angle, and scale consistent across all frames.
Keep the character anchored within the cell (no drifting off-center) unless the motion described requires a small in-place shift.
Make the last frame transition smoothly back to the first for a perfect loop.
SPRITE SHEET
Arrange the 16 frames in exactly 4 columns × 4 rows, ordered left to right, top to bottom.
Canvas: 1024 × 1024 pixels. Each cell: 256 × 256 pixels.
Use identical alignment and a fixed baseline across all cells.
Keep the entire character inside each cell, with at least 16 pixels of transparent padding on every side, including around moving accessories or effects.
No overlapping cells, grid lines, labels, text, or watermarks.
TRANSPARENCY
Use a genuinely transparent RGBA background with alpha zero outside the character. Do not draw a checkerboard or add a solid background, floor, or cast shadow. Preserve white and pale details inside the character.
DELIVERABLES
A transparent 4×4 PNG sprite sheet.
A transparent animated GIF of the single character, using all 16 frames at 256×256 pixels, looping forever with an approximately 2.2-second cycle.
A ZIP containing all 16 individual transparent PNG frames.
Use nearest-neighbor sampling if resizing is needed to preserve crisp pixels. Before finalizing, ensure no stray pixels, clipping, or background artifacts remain, and that the background is truly transparent.
