Dirty Flags in Rendering | Coding a 2D Game Engine in Java #15

In this tutorial, I give a simple way to set up a dirty flag system with our render batcher. This allows us to only rebuffer data that has changed, which should save some CPU time while rendering our batches. This also allows us to control how the data gets moved around everytime a value that we have interest in changes.
For a more complex example of a dirty flag system, Bob Nystrom has a great article here: https://gameprogrammingpatterns.com/dirty-flag.html
