Paths in BGE

1st off, Can I have an object move along a path in the bge. (like move foward along a path when I press w and backwards when I press s??)

and then can it rotate around the path?

Probably. Try an IPO, and properties.

Don’t know enough to give more, but hope it helps.

IPO is an option. To do the rotation, you can have one object following the path and another one rotating around the first one. Can be done with IPO again.

How could i do a path like movement with IPO?

Set the appropriate frame, move your “path-following”-object to the appropriate location with the appropriate rotation.
Press <i> make an RotLoc key.
Repeat this until you are happy with the motion.

Add an IPO actuator to the above object. Set it to property mode. set an prop (e.g. frame).
Add an property with the name you entered at the actuator (frame). Make it int or float.
Connect an always sensor (no pulses) with an AND controller connect with your above IPO actuator. That actiavates the actuator.

Every time you change the property frame the object will go into the postion of the IPO path represented by the property:

keyboard sensor “w” -> AND -> property actuator “Add” mode prop: frame value:+1
keyboard sensor “s” -> AND -> property actuator “Add” mode prop: frame value:-1

I hope it helps

That does help but i was looking for move of a servo control type movement. any possiblities?

you mean something like this: http://blenderartists.org/forum//showthread.php?t=184681?

yes thx. It’s much appreciated.
