Small rigid physics demo

Post by **marshallh** » Fri Sep 26, 2008 4:14 pm

I've always wanted to do some sort of physics sandbox to mess around with my own code. Well, the past few days I've written this program which simulates rigid point collisions and gravity.

Keys:
Insert - Add lots of balls
Delete - Remove balls
Arrow up - increase gravity
Arrow down - decrease gravity

Click anywhere in the window to spawn a new ball.

psh, that's nothing. Look into a program called phun. that's a full-blown 2d physics engine that allows you to do simple stuff like make circles and squares and free-hand shapes, but also does advanced stuff like hinges, springs, motors, liquids... a whole world of opportunity.

edit: oh, so you wrote this yourself? what language did you use?
do you plan on adding more to it with time?

I'm interested in what you wrote this in as well. Do you mostly do your development in Windows? Also, I noticed in the show yourself thread you were in college. Where ya at, degree, year, that sort of thing?

It's a 5 month old thread!

somebody bumped it I didn't look at the first date. It was fun any way

Big bump I know, but you wouldn't happen to still have the source for this, would you marshall?

Hmm, sorry about that. I guess Development Center threads are checked very often, I didn't even notice how old it was.

I ran it today and it ran at 400fps on my new beast graphics card. In literally less than 2 minutes I rigged a ghetto frame limiter to keep it from going too fast.

Dev-C++ to open the project and compile. The new binary is in there also.

I dont want to be the one to super bump this, but i think it is pretty cool. I would love to see this little demo turn into some type of game

It closed out on me, here's the log,

Code: Select all

Balls: 1101   Frames done: 35
Balls: 1106   Frames done: 35
Balls: 1112   Frames done: 32
Balls: 1117   Frames done: 34
Balls: 1122   Frames done: 34
Balls: 1126   Frames done: 34
Ball

I the "Ball" at the end is what it was.

It's already been done: http://www.phunland.com/wiki/Home" onclick="window.open(this.href);return false;

I got phun. It's fun. But I can't figure out how to connect hinges to two objects. I figure it's pretty simple.
