Thanks for the reply Jean
the key here would be to add a layer in between the object that is constrained to the path and your vehicle.
Can you elaborate on this, what do you mean by a layer? I have NO object constrained to the path. I have the
iTween Move To V2 placed on the bus itself, so I use
Game Object= Use Owner and the path set to the name of my iTweenPath... BusPath actually... I have Move to Path ON.
Then you went on...
have a dummy to follow the path, then have your vehicle following the position of the dummy ( using get position/set position dance between the dummy and the vehicle every frame)
then your vehicle will not spin.
OK, Havent tried this yet, think I understand... maybe.. but can you explain why this would work, Im not getting it really.. Id like to understand as well as just follow orders!!
To have your vehicle follow terrain if really bumpy, you might then want to raycast from the vehicle onto the ground, get the hit point normal and use that as a base for your vehicle to look at, so it will follow the path properly yet conform to the terrain bumpiness.
Can I do this with playMaker? Point me to the right action if you will?
Actually I'm quite surprised this was so tricky. I would have thought that this technique would be exactly the same as animating an NPC around in a animation or cut scene. In fact thats soon my next job, having a character walk around on paths..., the bus is a bit of a test...
Anyway. Heres a little film of the issue, I think you understood my predicament so this is just for fun really...
