    • drawFont3D

      public static void drawFont3D​(BitmapFont font, ExtSpriteBatch batch, java.lang.String text, com.badlogic.gdx.math.Vector3 position, com.badlogic.gdx.graphics.Camera 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.
    • drawFont3D

      public static void drawFont3D​(BitmapFont font, ExtSpriteBatch batch, java.lang.String text, float x, float y, float z, float size, float rotationCenter, com.badlogic.gdx.graphics.Camera camera, boolean faceCamera)
    • drawFont3D

      public static void drawFont3D​(BitmapFont font, ExtSpriteBatch batch, java.lang.String text, float x, float y, float z, double size, float rotationCenter, com.badlogic.gdx.graphics.Camera camera, boolean faceCamera, float minSizeDegrees, float maxSizeDegrees)
      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.
      x - The x coordinate.
      y - The y coordinate.
      z - The z coordinate.
      size - The scale of the font.
      rotationCenter - Angles to rotate around center.
      camera - 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.

      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.
