Here are a couple of my old QB programs. Well... kinda old. I made them about 1-2 weeks ago. In the first one, you control a cannon and try to hit the target. It simulates actual cannon trajectory physics. Each pixel represents one meter.
The second program is a simple and rather boring game where you try to jump the obstacle as is hurtles towards you at random speeds. I pretty much just made this as a memory refresher on bitmaping, sprites, and such.

Those are sweet!!! Feel bad for ya on that cannon 1, I've had to calculate all that stuff b4, fun, but long.. he he,.. :wink: Then you have to turn all the calcs upside down to get 'em to work in QB.. ^-^.. or atleast for Y since adding makes it go down not up..
