我有以下问题:当我将密钥卡渲染到屏幕时,它不会从最后一次清除自己。但是当我添加清晰的屏幕代码时,背景不可见。
没有清算的代码:
public void render(float delta) {
// Temporary variable
float zoom = camera.zoom;
frameBufferObject.begin();
{
// Render
sb.setProjectionMatrix(camera.combined);
sb.begin();
groundManager.render(sb);
sb.end();
}
frameBufferObject.end();
// Clear the screen
Gdx.gl.glClearColor(0.25f, 0.25f, 0.3f, 1f);
Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
// Render the images
sb.setProjectionMatrix(camera.combined);
sb.begin();
{
sb.draw(backgroundTexture,
camera.position.x - camera.viewportWidth * zoom / 2,
camera.position.y - camera.viewportHeight * zoom / 2,
camera.viewportWidth * zoom,
camera.viewportHeight * zoom);
sb.draw(frameBufferObject.getColorBufferTexture(),
camera.position.x - camera.viewportWidth * zoom / 2,
camera.position.y - camera.viewportHeight * zoom / 2,
camera.viewportWidth * zoom,
camera.viewportHeight * zoom,
0, 0, 1, 1);
// Render the ground
surfaceFragmentManager.render(sb);
}
sb.end();
}
但是当我添加
Gdx.gl.glClearColor(0.25f, 0.25f, 0.3f, 1f);
Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
它只是清除屏幕并用纯色绘制背景。
我怎样才能让自己清楚,并让背景可见?
谢谢。
