Check if object is rotating in an axis.

Hi, I was wondering if there is any way of checking if an object is rotating in a specific axis? As in,

if(this.transform.rotate.y ++)
{
//then…
}

Also, is there any way of causing an object to rotate in a specific axis without giving a point to rotate to?

Thanks in advance for your help.

By ‘rotate’ do you mean like spinning because of physics or something like that?

By rotate, I mean the object’s rotation.y increases so, yes, spinning :]
