BIG problem+Please Try it your self

[starkman]

Hi ,
i used AppForkLiftDemo code sample to make a big world with a car ;in first time it's work perfectly and no problem.

but if i change groundShape box size from 50 to 5000 like this code :

Code: Select all

btCollisionShape* groundShape = new btBoxShape(btVector3(5000,3,5000)); // i need to make a big ground so i set value's from btVector3(50,3,50) to btVector3(5000,3,5000)

when run application i see the car vehicle drop on the ground but not move when i press up key !

Please Try it your self ! (open AppForkLiftDemo sample and just change ground shape size from (50,3,50) to (5000,3,5000) ) !!

i need to make terrain with btBoxShape no want to use triangles mesh to collision.
how to solve this problem ????

Thank you for help.

You can still use btStaticPlaneShape, an infinite plane.
