Hi,
I was trying to get the hang of a swing type movement. I'm making a game of this http://www.youtube.com/watch?v=tE3xO17VaSc&feature=related . Anyone interested in taking part in this project is welcome.
Regards

How are you going to make that into a game? I don't see what you could do other than just watch it. If that's the case, you should just use some animation and camera movement. No need for physics. But maybe I'm wrong. It would help people give better answers if you give a detailed explanation of what you're trying to do with the concept.

Basically, If you press ,lets say for example, Q then that changes the speed of the arm swings. If you press A it slows down and so on.
regards

Don't use physcs. It's easier if you use anything how this:

var move=10;
var move2=0;
var move3=1;

function armswing()
{
me=arm;
while(1)
{
my.tilt+=move*time_step;

if(move2==0)
{move-=move3*time_step;
if(my.tilt<0)
move2=1;}

if(move2==1)
{move+=move3*time_step;
if(my.tilt>=0)
move2=0;}
if(move3>0.01)
move3-=0.1*time_step;
wait(1);
}}

Now the arm swings further and further. (not tested)
