Adding out parameter to method - run time error

Lesha.VH 3 years ago updated by Lazlo Bonin (Lead Developer) 3 years ago 5

I change method signature from 

public bool SetValue(float val) 


public bool SetValue(float value, out bool result)

Press Tools->"Build Unit Options" to completely rebuild database, and got run-time error:

MissingValuePortInputException: Missing input value for 'a'.
Bolt.ValueInput.GetValue (Ludiq.Recursion recursion)
Bolt.XUnitValuePort.GetValue (IUnitValuePort gettable, Ludiq.Recursion recursion, System.Type type)
Bolt.XUnitValuePort.GetValue[Object] (IUnitValuePort gettable, Ludiq.Recursion recursion)
Bolt.BinaryComparisonUnit.<Definition>b__19_1 (Ludiq.Recursion recursion)
Bolt.Unit+<>c__DisplayClass56_0`1[System.Boolean].<ValueOutput>b__0 (Ludiq.Recursion recursion)
Bolt.ValueOutput.GetValue (Ludiq.Recursion recursion)

Bolt Version:
Unity Version:
Scripting Backend:
.NET Version (API Compatibility Level):

out bool result is not used In Graph Flow (pink circle without any connections)

Well, may be its my mistake - however I can not extract information in what BLOCK this error occured...

I found my mistake on BIG graph - however get another

InvalidConversionException: Cannot convert from 'System.Boolean' to 'System.Single'.

Bolt.Unit+<>c__DisplayClass56_0`1[System.Single].<ValueOutput>b__0 (Ludiq.Recursion recursion)

Well - there is no information about in what block mistake take place - NO CHANGE TO DEBUG logic)

Such inforamation must be added - how to find run-time mistake...

And after refactoring method that are used in Graph, its very hard to find all mistakes - because lots of connections get lost...

Can you send screenshots of the graphs in which these errors occur? It's hard to guess what is happening from just the stack trace.
