LibGDX:ShapeRenderer绘图...没什么 [英] LibGDX: ShapeRenderer drawing... nothing

问题描述

所以绘制形状应该真的很容易，对吧?好吧，下面的内容什么也没画.

So drawing a shape should be really easy, right? Well, the following draws exactly nothing.

...为什么?

Gdx.gl.glClearColor(0, 0, 0, 1);
Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);

camera.update();
shapeRenderer.setProjectionMatrix(camera.combined);

shapeRenderer.begin(ShapeRenderer.ShapeType.Filled);
shapeRenderer.setColor(Color.WHITE);
shapeRenderer.rect(WIDTH / 2, HEIGHT / 2, 50, 50);
shapeRenderer.end();

推荐答案

确保相机已正确初始化.

Make sure your camera is properly initialized.

例如:

camera = new OrthographicCamera(); //Put this in init
camera.setToOrtho(0,0,WIDTH,HEIGHT);
