Any idea why the spring isnt working in this code?

try changing this line

PHY SET REVOLUTE JOINT SPRING 1,0.0,1.0

to this

PHY SET REVOLUTE JOINT SPRING 1,object angle x(3),1.0

But it still seems to have no effect? Am i right in assuming that this command will make the joint rotate back to the specified angle like its on a spring?

well I got the upright bar to spring backup when hit with the sphere using above code. not sure if thats were your tring to go with it.

Well thats kind of what i was hoping for but that code doesnt work for me? The spring command was set on joint 1 and i posted some code that had a kinematic command in it so joint one was solid, it shouldnt have effected the upright bar? Heres the code without the kinematic command and object angle(x), but im still not seeing anything different:



Is there an example anywhere of this command being used?

Let me see if I am on the same wave lenght.

Object 3, you what its so if one of the sphere's hit it, it will tilt say 45degs then return to the position it started at.


if that is so you may need an object to work as a spring on object 3.

Yeah thats exactly what i want, so how would i do that?

Sorry its just im completely new to DP and i assumed that i could use an object on its own as a spring.

When you use Dark Physics you have to think in real terms, so how would have built this in say wood.

1. there would be a spindle with a spring on it to keep it level.
2. this would then be connected to the horizontal bar that would then stay at position until you drop or touch it with some thing.

so to your code make a small sphere which you then connect to object 3.

will be trying out what I say should post something soon.

edit could be a long soon....

Ok, so ive now got it to the point where it springs back but how do i make it so that it only rotates on the y axis when the ball hits it?
