font.draw() works correctly on first call but not on second

问题

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.

Here's some of my code:

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();

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

回答1:

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.

This is a similar problem.
