post conditions

[tomdeblauwe]

Hello,
I have a question about post conditions. I have an action node that checks a certain state and outputs this as an int on the output named "state".

I wanted to have a post condition that would fail if the "state" output after the tick is for example not 5. That would be nice to use in a retry until success decorator.

Intuitively I would want to say _successIf="state == 5" in the xml for my node. But then I found out that is actually a pre condition, so that was not usable for this. But, something similar would be nice... I would like to be able to check after the tick of the node: when the tick() returns success, then execute a script, and override the tick success status by the result of the outcome of this script.

I see in code this is not supported, only a post tick function can change the status, but it has no scripting possiblity it seems?
What would be the best way to do this? I could use precondition decorator after this "GetStateNode" and check the output port value there, but it would be nice if it could be written more compact.

Best regards
