How to set the axis of btSliderConstraint?

[allenshen]

Hi,everyone,it seems the default axis of btSliderConstraint is 'X',how can I set the axis along the arbitrary vector?thx!

When setting up the slider, you pass in a tranform which contains the translation axis. So just set your axis vector in that transform.

Something like this

Code: Select all

btTransform tr = new btTransform;
tr.setIdentity();
tr.setOrigin(btVector3(0,1,0)); // whatever vector values you want for your translation axis
