Locking entities to an axis?

[shoffing]

Is there a way to lock entities to 0 on a specific axis?

I figured SetPos() would work:
[lua]E:SetPos(E:GetPos()*Vector(1,0,1))[/lua]

But the problem is the entity loses all of it's momentum when using that function, even when I do:
[lua]
local Speed = E:GetPhysicsObject():GetVelocity()
E:SetPos(E:GetPos()*Vector(1,0,1))
E:SetVelocity(Speed)
[/lua]

Is there another function I can use instead of SetPos() that will keep the velocity? Or would I need to resort to ApplyForceCenter()?

As always, thanks for any help.

Does anybody know?

[QUOTE]If the movetype of the entity is MOVETYPE_VPHYSICS (aka, if the entity uses physics simulations) you need to use :SetVelocity on the PHYSICS object of the entity.[/QUOTE]

Have you tried this?

[lua]
local Speed = E:GetPhysicsObject():GetVelocity()
E:SetPos(E:GetPos()*Vector(1,0,1))
E:GetPhysicsObject():SetVelocity(Speed)
[/lua]
