本文介绍了一个名为Uni2DEditorTextureAtlasPacker的工具，该工具专门用于Unity编辑器下的图集自动打包。文章详细解释了该工具使用的不同打包模式，包括最佳短边适配(BSSF)、最佳长边适配(BLSF)、最佳面积适配(BAF)等，并介绍了这些模式如何帮助优化资源布局。

Uni2DEditorTextureAtlasPacker：Uni2D图集打包工具。仅用于编辑器下自动打包。Uni2D图片打包采用了开源打包项目MaxRectsBinPack.cpp的源码，有Sven Magnus移植到C#版本。研究打包模式的话可以了解下这个，采用的打包模式如下：

public enum FreeRectChoiceHeuristic

{
RectBestShortSideFit,///< -BSSF: Positions the rectangle against the short side of a free rectangle into which it fits the best.
RectBestLongSideFit,///< -BLSF: Positions the rectangle against the long side of a free rectangle into which it fits the best.
RectBestAreaFit,///< -BAF: Positions the rectangle into the smallest free rect into which it fits.
RectBottomLeftRule,///< -BL: Does the Tetris placement.
RectContactPointRule///< -CP: Choosest the placement where the rectangle touches other rects as much as possible.
};
