font.draw()可以在第一次调用时正常工作，但不能在第二次调用时正常工作 [英] font.draw() works correctly on first call but not on second

问题描述

我不确定是否不允许您两次调用font.draw()，但是第一行显示正确，但是第二行非常故障，缺少很多字母[在第一行中看起来不错]和随机数似乎没有绘制.我的.fnt文件可以在按钮上使用，而复选框也可以.

I'm not sure if you're not allowed to call font.draw() twice but the first linedisplays correctly but the second one is very glitchy, a lot of letters are missing [that appear fine in the first line] and random numbers seem to not draw. My .fnt file is fine as it works on buttons and checkbox's just fine.

这是我的一些代码:

private BitmapFont font = new BitmapFont(Gdx.files.internal("test.fnt"),false);
private SpriteBatch batch = new SpriteBatch();
//in Render Method

    batch.begin();

    font.draw(batch, "Best Distance: " + bestDistance + "m", Gdx.graphics.getHeight() / 2, Gdx.graphics.getWidth() / 2);

    font.draw(batch, "Distance: " + finalDistance + "m", Gdx.graphics.getWidth() / 2, Gdx.graphics.getHeight() / 2);

    stage.draw();


    hud.stage.draw();


    batch.end();

如果我切换他们的绘图调用的顺序，那么哪个被称为第一个正确绘制.

If I switch the order of their draw call then whichever one is called first draws correctly.

推荐答案

您正在调用stage.draw()而不关闭spritebatch.在开始绘制舞台之前，只需调用batch.end()即可. 在另一个打开的批处理中渲染一个批处理将导致各种奇怪的行为，使您认为错误不在于该批处理而已.

You're calling stage.draw() without closing the spritebatch. Simply call batch.end() before starting to draw the stage. Rendering a batch inside another opened batch will result in all kind of weird behaviour that makes you think the fault lies in everything but the batch.

这是一个类似的问题.
