    • drawSprite

      public static void drawSprite(Sprite sprite, com.badlogic.gdx.graphics.g2d.SpriteBatch batch, float x, float y, float z, double size, float rotationCenter, ICamera cam, boolean faceCamera, float minSizeDegrees, float maxSizeDegrees)
      Draws the given sprite using the given font in the given 3D position using the 3D coordinate space. If faceCamera is true, the sprite is rendered always facing the camera. It assumes that ExtSpriteBatch.begin() has been called. This enables 3D techniques such as z-buffering to be applied to the text textures.
      Parameters:
      sprite - The sprite.
      batch - The sprite batch to use.
      x - The x coordinate.
      y - The y coordinate.
      z - The z coordinate.
      size - The scale of the sprite.
      rotationCenter - Angles to rotate around center.
      cam - The camera.
      faceCamera - Whether to apply bill-boarding.
      minSizeDegrees - Minimum visual size of the text in degrees. Zero or negative to disable.
      maxSizeDegrees - Maximum visual size of the text in degrees. Zero or negative to disable.

    • drawFont3D

      public static void drawFont3D(BitmapFont font, ExtSpriteBatch batch, String text, com.badlogic.gdx.math.Vector3 position, ICamera camera, boolean faceCamera)
      Draws the given text using the given font in the given 3D position using the 3D coordinate space. If faceCamera is true, the text is rendered always facing the camera. It assumes that ExtSpriteBatch.begin() has been called. This enables 3D techniques such as z-buffering to be applied to the text textures.
      Parameters:
      font - The font.
      batch - The sprite batch to use.
      text - The text to write.
      position - The 3D position.
      camera - The camera.
