如何获得BitmapFont文本的总宽度？

font.draw(batch, text ,Gdx.graphics.getWidth() / 2 - /* text width */ /2,450);

Answer 1

Use a GlyphLayout to calculate the width of some string using a particular font:

GlyphLayout layout = new GlyphLayout(font, text);
float textWidth = layout.width;

Don't put this in the render method, though. It is a good idea to calculate and store this value once in create or show and then just use the value in your render .
