在SpriteBatch.begin/end中嵌套ShapeRenderer.begin/end [英] Nesting ShapeRenderer.begin/end in SpriteBatch.begin/end

问题描述

是否可以在SpriteBatch begin和end调用之间使用ShapeRenderer绘制形状.

Is it possible to draw shapes by using ShapeRenderer between SpriteBatch begin and end calls.

我尝试过但没有结果，只绘制了SpriteBatch纹理，没有任何形状.示例代码如下:

I have tried but no result, only SpriteBatch textures are drawn, no shape is on the scene. Sample code is as followed below :

shapeRenderer.begin(ShapeType.FilledCircle);
shapeRenderer.setColor(0f, 1f, 0f, 1f);
shapeRenderer.filledCircle( 100, 100, 100);
shapeRenderer.end();

我有一个通过以下命令创建的正交摄影机:

I have a orthographic camera created by these commands :

camera = new OrthographicCamera(1, Gdx.graphics.getHeight() / Gdx.graphics.getWidth());
camera.setToOrtho(true);

推荐答案

ShapeRenderer和SpriteBatch都在OpenGL中设置了它们希望在使用过程中保持不变的状态.嵌套它们会产生问题.请参阅此帖子在badlogic论坛中.

Both ShapeRenderer and SpriteBatch set state in OpenGL that they expect to remain constant during their use. Nesting them can create problems. See this post in the badlogic forum.

应该在文档中更清楚地说明这一点.

This should probably be spelled out a bit more clearly in the docs.
