Specify defalt state

[SYkirk]

I've created two new states as the user guide shows, but it throws "InvalidAgentState" exception with the message "does not contain state 'default'" everytime I run it. I've gone through the user guide to search for information about agent state but failed to solve it . How should I deal with the situation when defining and initialising agents with more states? Many thanks!

There are two possible causes I can think for this off the top of my head.

1. You're using an old build of FLAMEGPU2 and spatial messaging, there was a bug that causes this exception to be thrown and has been resolved.
2. You're calling a function which has a default argument default and need to specify the desired state. The most obvious one that comes to mind is FLAMEGPU->agent(agentName, stateName) within the HostAPI (this is what caused the above bug).

If you could grab the call-stack or location the exception is being thrown from, it would help narrow down the cause.

The problem was confirmed as issue (1) via email.

I used uDiscreteColor to construct my own color as the guide shows, like:

cmap = pyflamegpu.uDiscreteColor("health", pyflamegpu.WHITE)

cmap[0] = pyflamegpu.Color("#97FCAB")

But it throws the exception:

This appears to be a bug due to an oversight. The DiscreteColor types extend std::map. So we had assumed the SWIGs stdlib wrapping would be automatic, but it appears not.

I'll let you know when it's been fixed, this will require you to get a new python wheel.

I've now fixed it in the pull request here.

I will merge it ASAP, and set new wheels building for you.

You should be able to download a new binary wheel in ~3 hours.

You can find all the new wheels built with the bugfix here: https://github.com/FLAMEGPU/FLAMEGPU2/actions/runs/3021752398#artifacts

As before, they are only available for 5-7 days after which they will expire.

The new wheel has been installed and it works!

Thanks a lot!
