So I’m in the process of creating the ‘world’ in my 2D Game and have just finished being able to render the floor tiles and when the player moves left/right new tiles are generated, however this means the tiles outside of the screen are still there and it’s creating very bad performance issues.
Is there a way to render the tiles only within the view able area of the screen, a point in the right direction would be great, I’m not looking for pages of code 
Thanks!
