Adding two joints to one body

Postby Lax » Sat Jun 26, 2021 5:13 am

Hi folks,

is it somehow possible to add two times the dCustomSlider slider to one body?
I want to move a spaceship on x, z-axis with limits. So I need two dCustomSlider slider, one for x-pin and another one for z-pin. But as soon, as I add them two times to the same body, my application will hang forever without a error message, but I see a warning in a thread:

warning!! bilateral joint duplication between bodied: 8 and 1
warning!! bilateral joint duplication between bodied: 8 and 1

Yes that's not allowed.

If you need to move a body in the x, z direction, that the y plane. You can use a plane 2d joint.

ok, but the plane2D has not limits. I need to limit the movement.

If it had limits, would it be what you need?

It is very eassy to subclass it and add limits to it.

Yes, Plane with limits would be great! Of course depending what the normal of the plane is. Like slider joints, e.g. minHorizontalLimit, maxHorizontalLimit, minVerticalLimit, maxVerticalLimit.

Ok I will make one with limits and post here later.

You can take it and paste it in you code the made changes to it if you want.

I assume the body does not rotate since you were trying to do it with sliders.
