Rotation but keep going straight???

[Nicollini webforumsuser@macromedia.com]

I have model that I'm translating along the x axis e.g.(pModel.translate(2,0,0)).
At a certian point on the x axis e.g.(if pModel.transform.position > 50 then) I would the model to rotate relative to its y axis while still translating:

e.g.
pModel.translate(2,0,0)
if pModel.transform.position > 50 then
pModel.rotate(0,1,0)
end if

The problem is that when the rotation starts the model curves off its straight line direction.

Can anyone tell me how to keep the model on the same direction whilst rotating???

Thanks.

Hi Nick,

The problem is that you translate according to the objects coordinate system. When you rotate the object, the coordinate system also rotates.
The solution is simple. Do you translation according to world coordinates.
pModel.translate(2,0,0, #world)

Maybe you have to specify an other vector. This depends on where your object is located and how it is rotated at the beginning.

Hopes this works for you,

link your object to a non-visible parent object. apply the translation to
the parent and the rotation to the child.
