I am total new to Blender,already saw dozens of tutorials, got a lot of those. But still need help on some issues.My project is about real-time simulation of crane in the Blender, for a beginner, i started from make 1DOF boom with one cylinder.
I choose all the parts as rigid bodies and make constraint with rigid body joints so that cylinders and booms are connected with each other.Also, i have the ‘TRACK TO’ constraint to rod and body of cylinder. What i want to get in the simulation is like when the second boom falls, the cylinder rod retracts and stops when it collides with the cylinder body.
Here is the problem, when i simulate in the game engine, the TRACK TO constraint does work and the second boom just falls and the cylinder rod just falls.
I have been doing this for the whole day but can not find any solution. Could someone offer some ideas or anything that i made is not correct ? Thanks!!!
P.S I have uploaded the file.See below =)
