Quad (简体中文)

携带纹理坐标信息的矩形区域。

矩形区域可以选择纹理的一部分进行绘制。使用这种方法,将一张大图读取进来 texture atlas,切分成一张张的小图片。

O.png 矩形区域被缩放、旋转后会失真, rotated or drawn at non-integer coordinates, even within SpriteBatches, to compensate for this, use 1px borders around the textures inside the texture atlas (preferably with the same colors as the actual border)
