libgdx TextureRegion to Pixmap

Question

如何从TextureRegion或Sprite创建Pixmap？我需要这个以改变一些像素的颜色，然后从Pixmap创建新的纹理（在加载屏幕期间）。

Answer 1

Texture texture = textureRegion.getTexture(); 
if (!texture.getTextureData().isPrepared()) { 
    texture.getTextureData().prepare(); 
} 
Pixmap pixmap = texture.getTextureData().consumePixmap(); 

如果只想纹理（区）的一部分，那么你就必须做一些手工加工：

for (int x = 0; x < textureRegion.getRegionWidth(); x++) { 
    for (int y = 0; y < textureRegion.getRegionHeight(); y++) { 
     int colorInt = pixmap.getPixel(textureRegion.getRegionX() + x, textureRegion.getRegionY() + y); 
     // you could now draw that color at (x, y) of another pixmap of the size (regionWidth, regionHeight) 
    } 
}
