I thought about how I could figure where darts have hit the board and my first idea went to a separate texture used to keep sector IDs encoded in color data. I've spent about two hours making it using Paint.net and the result is aesthetically pleasing, if I say so myself!
Someone suggested that I could've used maths in order to get the zones, which is theoretically true; I could calculate the distance between the middle of the board and the dart, then the angle in order to figure out where the dart landed. I suppose it could work, yeah, but my method works, so I'm not going change it - this is a game jam after all! Now, what's left? Designing the spells, enemies and progression mechanics of the game. I have a few more days to do so, this should be doable!
Time spent on this project: 17 hours
