# rotating many objects together using logic bricks / python

hi!

i am making a simple game using blender’s physics engine, where you need to transport the ball through the maze and the trick is that you manipulate not the ball directly, but the playfield (i.e. maze). the problem is that when i rotate the playfield object (using logic bricks - i am an absolute beginner), it actually pushes/kicks the ball and the whole operation looses its precision. Instead I would like to rotate both playfield AND the ball, so all the movement is an effect of gravity force, not the objects interacting.

the question is thus the same as in the title: is it possible? experiments i have made with “parenting” resulted in absolutely strange behavior of the ball and grouping does not work as far as i understand it. i would be grateful for any kind of guidance in this matter.

Here is a game like you are describing…

Works in MAC , Linux and windows

He is using a quake 3 map, which is totaly static (dose not move)

He is making the table look like it is rotating, but in all reality the ball is just moving in a direction, and he is tilting the camera and the sky box.

one of my favorite games of all time!! Glad to see someone trying a blender GE version

the question alters to: how do i change the direction of bullet gravity force? Thanks :)! i am sure there should be more elegant approach than turning the gravity off and applying it sepparately to each and every object.

if you liked neverball, be sure to get interested in other similar games (because of wii it became almose a “genre”) - search wikipedia for “super monkey ball” or “gooball” and google for others.
