我已经使用纹理绘制来绘制2张图像,但是背景图片变成了黑色。源图片是png,它是透明的。我该如何解决?
如何用透明效果渲染原始图像?
最佳答案
试试这个:
spriteBatch.begin();
//background
seaTexture = new Texture(px);
Color c = spriteBatch.getColor();
spriteBatch.setColor(c.r, c.g, c.b, 1f); //set alpha to 1
spriteBatch.draw(seaTexture, 0, 0, 480, 320);
//foreground
c = spriteBatch.getColor();
spriteBatch.setColor(c.r, c.g, c.b, .3f);//set alpha to 0.3
spriteBatch.draw(blockTexture, 50, 100, 120, 120);
spriteBatch.end();
