Spritebatch, Textureregions, and Sprites

TextureRegion

TextureRegions can be created without a texture. This is useful if a region should be populated with a texture at another point in time. Doing so however bears the risk of a NullPointerException if this initialization is not done and the region is drawn. To prevent this, draw calls can be protected:

  1. private SpriteBatch spriteBatch = SpriteBatch();private TextureRegion textureRegion = new TextureRegion();@overridepublic void render(float deltaTime){  spriteBatch.begin();  if(textureRegion.getTexture() != null)   {     spriteBatch.draw(textureRegion, 0f, 0f, 1024f, 512f);   }  spriteBatch.end();}
