【问题描述】：
目前在我的render() 中，背景颜色设置为白色，但是当我将其更改为白色时，我根本看不到我的效果。
我想知道是否有需要启用的选项或我可能错过的代码行？
public void render(float delta) {
Gdx.gl.glClearColor(0, 0, 0, 1);
Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
batch.begin();
effect.update(delta);
effect.draw(batch);
batch.end();
}
//这里是.p文件

不知道如何使 .pfile 看起来像道歉的代码:(
【问题讨论】：
-
显示渲染代码，否则我们无能为力。
-
将其添加到问题中。请添加 effect.p 或告诉我们它是什么效果，如果它非常透明甚至是白色，您将看不到它。这段代码肯定没问题。
-
所以是的，我在 .p 文件中没有看到任何可以让我在白色背景上显示粒子效果的选项？
-
另外效果肯定不是白色是默认的橙色和红色
-
测试过了。可能是 libgdx 的一个错误。使用白色背景，即使您更改纹理颜色或类似的东西，也看不到任何效果。但是，通常你应该有任何背景，所以这不应该是一个问题。去 badlogic 论坛里问这个问题。
