Hello,

I need to perform multiple rotations on a node, but:

node.getLocalRotation().fromAngleAxis(PI, Vector3f.UNIT_X).fromAngleAxis(PI, Vector3f.UNIT_Y);

just does the last rotation.

What is the correctway of rotating a node several times (acculating the rotation) ?

Thank you in advance

The **fromAngleAxis** method *sets* the Quaternion to the desired valueâ€¦ in other words, it always overwrites whatever the value you had, and replaces it with a Quaternion that represents a rotation (from identity) along one axisâ€¦ What you want to achieve can be done by chaining the rotation with multiplication:

Quaternion local = new Quaternion();

local.fromAngleAxis(PI, Vector3f.UNIT_X);

node.getLocalRotation().multLocal( local );

local.fromAngleAxis(PI, Vector3f.UNIT_Y);

node.getLocalRotation().multLocal( local );

It's also possible with Quaternion.fromAngles, it takes 3 angles, one for UNIT_X, UNIT_Y and UNIT_Z and combines them togetherâ€¦

Thank you very much my friends, that did it.
