So I pulled:
And was kinda interested in the baseball thing. Basic setup is you are a bored convenience store employee, and you are playing home run derby in the store. The objective is to knock as much stuff off the store shelves as you can. The number of pitches is limited, and each time you miss a pitch, you have to take a drink, which will make hitting the ball even more difficult
I got the skeleton of the project up and running over the weekend, and had balls bouncing off walls, simple friction calculations in, etc. Last night I got the balls colliding with the racks, which will be holding objects (boxes, bags, bottles, etc). These will go flying when you hit a rack at sufficient speed. I'm thinking of giving the player a choice of strong or weak swings. Combining that with the angle of the bat and timing should give the player adequate control over 'shot' placement, with enough practice (and without getting too damn drunk).
There's enough math and art involved to keep me busy for a few weekends. I definitely won't be pulling this out of my ass in one day like I did last time... heh
