我想要做的是检查具有黑色边缘的 2 个纹理的完美像素碰撞,例如:此纹理之一是圆形,第二个可以是三角形或矩形。
这是我的代码,它只给我颜色数组,没有我需要的坐标
Color[] playerColorArray = new Color[texturePlayer.Width * texturePlayer.Height];
Color[] secondColorArray = new Color[secondTexture.Width * sencondTexture.Height];
texturePlayer.GetData(playerColorArray);
secondTexture.GetData(secondTextureArray);

我的问题是如何从 Texture2D 获取此 Texture2D 中每个黑色像素的坐标。
感谢提前:)
