mining, gathering, resource management....

Hello all, I have tried searching for this but to no luck.

What I need is for the player to move a "gather" machine over a resource (ore, gold, fuel) the machine would then mine the resource and place it into bulk boxes which are then loaded onto transports and taken back to the main base. The transports can be hijacked by enemy team etc... The main thing I need is a way to give an object a resource number and deplete it as well as transferring that information to the raw mat containers...

so, anyone know where I can find this documentation?

Tks
