What is wrong in this graph?

[Ts1nd]

I am getting this error at the bottom. Its rather simple function with string input and float output.Whats wrong?

Technically, nothing’s wrong. It’s a Bolt quirk. When logic outside the superunit wants to access your Value output, Bolt can’t get it because (at least by my guess) it tries to retroactively execute the logic that produces that value but it’s too complex for it to handle retroactively hence the “value cannot be fetched dynamically, it must be assigned” error.

The solution to this issue is always the same - assign the value ie cache the value inside of a variable (a graph variable inside this superunit might work - use Select on Flow output and Set a graph variable with it and then Get that same variable for the superunit’s Value output. I don’t recall if graph var was enough or you have to use object scope variables, but graph var should work in theory. There’s also the “cache” node that you can experiment with.

Thanks for your reply. I already tried using graph and flow variables but got same error. It’s sad that even simple things like creating function with 1 output is basically out of scope in Bolt. I encounter numerous problems like this and spend hours looking for solutions, that’s ridiculous! I wish there was a way to convert my entire bolt code so far into C# so I would continue from there…

Note that you must implicitly use the Get Variable unit rather than the output of the Set Variable for the final superunit output value. I think if you use the output of Set Variable directly, it still tries to retroactively Set the value. Get Variable should work (in theory).

I tried Get and it still didn’t work. I ended up leaving 2 outputs values 1 from top and the other bottom calc and then when using this function I need to connect it to the right output which basically defeats the purpose of this function which was to create the “get variable” without having to use the get dictionary each time and also use the right dictionary based on input so in my example either “stats” or “combat”. I have similar function with set variable and it works fine but that’s because it doesn’t have any output unlike this one.
