It turns out that I actually used a lot of the code in the OmniRPG project to get a mockup and the source was available for that. The Pokemon Amber project is essentially dead, but I did look through the code and try to get it up and running. The code was super convoluted and poorly documented, so it would have been difficult to expand upon.
However, it did inspire me to work on an
RPG engine (also incomplete) if you are ever feeling motivated! Here's an up-to-date .gif of the example for the project:
You can see the coordinates in the upper right that are on for debugging, and the name input leaves a lot to be desired (in fact, it doesn't even work yet
)
