Render BitmapFont in 3D libgdx with ModelBatch

问题

I want to render a BitmapFont within a libgdx ModelBatch. I've only found samples with "SpriteBatch". Of course I can move the SpriteBatch around in 3D space, but it is either rendered before or after the "ModelBatched" objects. But I'd like to have it rendered in the correct z position.

E.g.

• Render modelInstanceA (z=20)
• Render Font (z=30)
• Render modelInstanceB (z=40)

Then modelInstanceB should cover Render Font should cover modelInstanceB.

In other words I'd like to render a font within a ModelBatch context.

modelBatch.begin(camera);
modelBatch.render(modelInstanceA);
modelBatch.render(font);
modelBatch.render(modelInstanceB);
modelBatch.end();

Is there a built in way to achieve this?

回答1:

If the models are opaque, you could draw your text with SpriteBatch after the modelBatch.end() call, but you'd need to call Gdx.gl.glEnable(GL20.GL_DEPTH_TEST); before spriteBatch.begin(). Then disable it after spriteBatch.end() to clean up (libgdx classes by default expect it to be off).
