Default How to throw a ball and make it bounce - 07-02-2011, 11:04 AM

Hi guys for my school project i need this and I dont know how to do it

I already figured out that Vehicle make it hold the ball with either hand of a character

but how Can i make it throw it in a realistic parabolic path way and as it hits the ground or the wall to bounce back

That would require a very complicated set of code, as having something stop when it hits an object is hard enough, but having it bounce off realistically is another thing all together. Unless you want something that looks more like \/ that than a parabola, I doubt many of us can help you, if any.

well as Tau pretty much said, this is a hard task to do, but your best bet for the path it moves is just make a predetermined pathway for the ball and use dummy objects set in a parabolic path, but if you need to be able to actually control the ball to move different amounts, I can't really help there


If you are stuck on a project, check out the tutorials I made here at this link:

There are lots of tutorials on it so far, including some youtube videos, check it out

Or..

This is just an idea and it may not be mathmatically but what if you try something like...


Code:
while(object's distacnce above ground>some sumber)//This is the only part that I can think will cause problems.
{
       doTogethor
        {
           object move forward at speed "some speed"
           object turn forward at speed "some speed less than the one above"
              }
}

There are a few problems with this(though a good idea to use) it doesn't give a parabolic look, and using collision is kind of bad. but if you need the ability to move your character or ball before throwing, this is probably among your best bet

Really I thought it looked pretty close to a parabola, you just have to tinker with the numbers a bit.

Okay scratch that I actually remembered an older thread that solves most of you problems.
