collision, near, touch, radar, and ray sensors do not work for me in blender 2.41. is there any way to fix this? i think its a bug that everyone has but im not sure.
Yes they are bugs for bullet. But I think they should still work for the sumo physics engine.

no, im using sumo and they still dont work 
i have to use sumo for projects with a vehicle because the rigid body seems to always be on in bullet.
They work for me in 2.41. I’ve found that the object colliding must be an actor. So it doesn’t work well for everything I suppose.
very strange :o i dont know what is going on. i need the near sensor to work and… well it doesnt.
