| 技巧 | 说明 |
|---|---|
加 pixel perfect | 防止 AI 生成模糊的"伪像素" |
| 指定色值 | 如 #0b1220 背景、#7cba3d 草地，保持色调统一 |
| 指定尺寸 | 32x32 px 或 64x64 px，防止尺寸混乱 |
加 transparent background | 方便后续图集打包 |
加 sprite sheet | 角色动画直接出序列帧 |
加 game asset | 让 AI 理解这是游戏素材而非插画 |
加 top-down view | 统一俯视角 |
加 seamless tileable | 地形瓦片需要无缝拼接 |
Agnes API 集成
项目主要使用 Agnes Image 2.0 Flash 生成建筑精灵图。
API 调用示例
bash
curl https://apihub.agnes-ai.com/v1/images/generations \
-H "Authorization: Bearer $AGNES_API_KEY" \
-H "Content-Type: application/json" \
-d '{
"model": "agnes-image-2.0-flash",
"prompt": "Dark pixel art tavern building, 96x128 px, top-down perspective, medieval two-story, hanging sign, warm interior glow, stone ground floor, wooden upper floor, pixel shadow below, transparent background, pixel perfect, game asset, inspired by Stardew Valley, low saturation, muted dark tones",
"size": "1024x1024",
"extra_body": {
"response_format": "url"
}
}'生成后处理流程
Agnes API → 下载图片 → 裁剪目标尺寸 → 去背景 → 按类别存入文件夹 → TexturePacker 打图集 → 上传 R2Prompt 最佳实践
