For my computer science class we have to make a game using xojo. I was wondering if there was an easy way to make an object jump( just the default ones). I want the object to go up, then come back down smoothly.
any help is appreciated 
You could try a simple Timer to move the object.
Check out this 2D engine made for Xojo to see more sophisticated techniques:

Also, check out the Flappy Bird clone at http://www.xojo.com/blog/en/2014/03/flappy-bird-in-xojo.php. It uses OpenGL so might be beyond where you are at right now (or maybe not!). As Paul says, the simplest way you could get something moving is probably with a Timer.
thanks for the answers, ill check out the physics engine also
Â… and you may want to have a look at the animations examples, included in Xojo!
and now I just found a little test which I wrote for myself some time ago: a bouncing arrow. You can download a zipped rbp from here:
