Hi Ivan,
I don't know how to decrease the amount of resources. Documentations say it is not possible. But I have found a simple workaround:
Build the following system outside of your main system:
Entity generator: 1/s
First server: server time, you put the time point at which the decrement in resources must happen. Server capacity = infinite.
Resource acquirer: acquire the amount of resources by which you want it to decrease.
Second server: Server time, long enough that it will keep the entity during the entire simulation. Capacity = 1.
And last a terminator.
This system holds the resources during the simulation which in practice seems like a decrease. Hope this helps.
