Hey, I tried adding a random fish that would swim around and you could chase (I think we should have lots of these) and it turned out okay, but definatly still in the beta mode. The fish is slow to turn the opposite way that your coming from, and doesn't swim around on it's own until you chase it. I just wanted to upload this so you could try building off it if you want to do something. I suggest you try making birds that you can jump up and bounce off, because that's deffinatly out of my capability. I could make it so that If you hit a bird you just shoot straight up (like in the iphone/ipod touch app mega jump in case you don't know it here's a youtube vid: youtube.com/watch?v=E8ehZRiYORE&feature=fvwrel) but I can't make it bounce off it normally. If you were gonna do that you could make it so when it hits something it bounces off in the direction of the mouse cursor? I don't know, maybe we should ditch that idea all together and just make the shark eat birds when it hits them. Anyways, good luck with what ever you're gonna add :D PS I had an idea for the fish AI, instead of always having it's x or y velocity 7 or -7 we should set it so it's always the sharks x or y velocity, get it?
