Agents in a state different from default state from the XML file

[daniele-baccega]

Hi,
I tried to initialise an agent to a particular state (different from the default state) using the <state>...</state> tag from the XML file, but it does not work because I do not have that agent inside the simulation (I also created the state for the agent using the function newState(...)). Do you know why?

Thank you very much

I've just looked at the IO test case, this covers the behaviour you're having a problem with.

It has two agents:

• Agent a:
  • State: default (no bespoke states)
• Agent b:
  • State: 1
  • State: 2

It exports and reimports agents in the a:default and b:2 states. I'm not aware of this test failing recently, so could you could please provide some greater detail so that I can help you find whether you've made a mistake or discovered an edge-case we're not testing for.

Similar to the logging issue when calling CUDASimulation::setPopulationData(), you will need to pass your state's name as the second argument (otherwise it defaults to default, header here).

But I do not call the function CUDASimulation::setPopulationData() because I'm creating and initializing the agents from the XML file specifying in the tag the desired state

Hmm, I'll investigate this further later this afternoon (I'm in and out of meetings for the next 2 hrs)

Ah found the bug.

FLAMEGPU2/src/flamegpu/simulation/Simulation.cu

Line 199 in 193fd83

setPopulationData(*agent.second);

Should be setPopulationData(*agent.second, agent.first.second);.

I'll create a quick PR, can merge it after CI passes (probably ~2 hours).

It works, thank you very much!
