Like the title says. Run the code, hit the up arrow to move the block then wait until it has come to a complete rest. After that the object no longer responds to SetObjectlinearVelocity

It might just be that the object is allowed to sleep, you can disable sleeping with a command like Set3DPhysicsObjectCanSleep, then the objects physics shouldn't switch off - it's a shame we can't automatically wake up an object by specifying it's velocity.
The code is dark and full of errors

The way it was setup was to give you full control. If you want to apply a force to a
dynamic object you must wake it up first. Then you decided when you want to put it to sleep.
That way all dynamic objects are put to sleep automatically by the physics engine unless you
decide otherwise. In conclusion if the SetObject3DPhysicsLinearVelocity command automatically
woke up the object and then applied the velocity you would not know it was stuck awake and would never go
back under the control of the physics engines sleep mode.
The coffee is lovely dark and deep,and I have code to write before I sleep.
