First Verlet Test

[KeauHou]

Hi,

this is my first post and my first approach of an physics engine^^

I don't know how to check for collisions and there is no friction yet, but im still working on that...

Keys:

• 1 = create circle
• 2 = create square
• x = reset
• left click = new particle
• right click = connect 2 particles
• space = pause
• tab = catch particle for moving with mouse
• escape = exit

EDIT: Yeah, this is just crap but currently I'm re-writing this in C & OpenGL. I'll post it here soon ^_^

I have rewritten the whole thing in C (last one was written in PureBasic). But I just can't get the collision working. I had some ideas but they were just ideas ^_^
I need something to test if two lines are crossing, but I can't get it right, maybe someone could help me :P

This is what it looks at the moment

Not a bad start :-)

I'd like to take a look at your source - if you're willing to share it...

google "line line intersection algorithm" and you should be all right.

cheers,
Mike

I am struggling with polygon collisions myself atm. good luck

Thx I googled in german so i didn't found anything usable...
This is my first project in C and it isn't really efficient also I don't made comments yet
I can send you my source when it's a bit clearer

Now I can detect collisions but i can't calculate the impulse, but im working on that.

How's the project going?

I don't have much time at the moment

the first post is post #4 in the topic for some odd reason. Somehow or the other it looks like the id of the first post ended up getting updated, and other posts after it didnt.

no it's not..... also that's pretty off-topic.

back on topic, uh... back on topic!!!

I've actually been working on collision detection myself, for my own Verlet physics engine. I would be glad to share some helpful tutorials I've been using for that.

Hope that helps!

By the way, you can see the latest progress on my physics engine here, on the Dejeweled Development Blog.
