Path nodes in jj2? Too hard in my opinion. I have another idea. If we can somehow detect events in the level we could remake those blank events to jump events (bots will jump if they detect this event in their pos), buttstomp event (if in air, they buttstomp), special move (kick or uppercut), ...
The bot program will automatically read the bot's pos, look for these events in the memory and do what they say.

The program should create a log like this:

Jump event on pos: 32,53
Jump event on pos: 76, 27
Buttstomp event on pos: 54, 143

Bot pos: 32, 53
Orders: Jump

All this would only be possible if we could just detect events in the level.

I haven't tried anything like this before but I think it would be possible or at least I hope so...
