Question

我为自己写了一个小游戏，现在我遇到了需要将两个TextureRegions放在一个纹理上的问题。我已经用Pixmaps尝试了它，但它对我不起作用。有没有办法解决这个问题

您是如何使用Pixmap的？这非常有效：

    Pixmap combinedPixmap = new Pixmap(totalWidth, totalHeight, Pixmap.Format.RGBA8888);
    Pixmap pixmap1, pixmap2;
    Texture texture1 = Your texture region.getTexture() /* Your texture region 1 */;
    Texture texture2 = Your texture region.getTexture() /* Your texture region 2 */;
    TextureData data1 = texture1.getTextureData();
    TextureData data2 = texture2.getTextureData();
    if(!data1.isPrepared()) data1.prepare();
    if(!data2.isPrepared()) data2.prepare();
    pixmap1 = data1.consumePixmap();
    pixmap2 = data2.consumePixmap();
    combinedPixmap.drawPixmap(pixmap1, 0, 0);
    combinedPixmap.drawPixmap(pixmap2, 100, 0);
    Texture finalTexture = new Texture(combinedPixmap);

如果由于某种原因没有，您可以使用Framebuffers。

    FrameBuffer fbo = new FrameBuffer(Pixmap.Format.RGBA8888, totalWidth, totalHeight, false);
    fbo.begin();
    Gdx.gl.glClearColor(0,0,0,1);
    Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
    spriteBatch.draw(region1, 0, 0);
    spriteBatch.draw(region2, 100, 0);
    spriteBatch.flush();
    fbo.end();
    TextureRegion combinedRegion = new TextureRegion(fbo.getColorBufferTexture());
    combinedRegion.flip(false, true);
    Texture combined = combinedRegion.getTexture();
