sprite_sheet_slice — GFX2D sprite op

• 数据种类:rgba → sprites

• 调用:import gfx2d; gfx2d.sprite_sheet_slice(sheet, tile_height, tile_width, margin=0, spacing=0, count=None)(或 opsgfx2d.get("sprite_sheet_slice"))

用法

把精灵图集切成等大的 `rgba` 帧列表,行优先。

> 以下的详细说明为原文 —— 摘要与标题已翻译。

`margin is the border around the whole sheet, spacing` the gap between

neighbouring cells — the two numbers that every atlas exporter writes and

that every hand-rolled slicer gets wrong by one.

Returns a `list of (tile_height, tile_width, 4)` arrays. With

`margin=spacing=0 it is the exact inverse of :func:tilemap_render`.

Raises ValueError: a sheet that does not contain a whole number of cells

(a partial cell means the margin/spacing are wrong, and silently dropping it

hides that), a `count` larger than the grid, more than

:data:MAX_SPRITES cells.
