agent.getCoords is not a function -- mysterious error message #363
Comments
Yeah, this is a known problem with NetLogo Web's runtime typechecking (in that it often doesn't exist). I thought we had an issue open on this, but we didn't, for some reason. Consequently, I've opened NetLogo/Tortoise#184 for this. Closing this as "moved". |
I find it very unclear when issues should go to Tortoise and when to Galapagos. They are described on the NetLogo GitHub page as Galapagos and Tortoise |
Well it doesn't really bother me when someone opens an issue in one repo and I find it more appropriate to put it to the other repo. Where the error is coming from is not something that I expect third parties to be aware of, and often involves some investigation even on my part to find out what the relevant code is. But, to somewhat clarify the difference between the two, Tortoise houses the NetLogo Web compiler and simulation engine. Using that stuff, it is entirely possible to run NetLogo Web models without a GUI. Galapagos adds the GUI and all the actual web machinery. I feel like actual bugs in Galapagos are somewhat rare, since Galapagos is largely just the UI that stands between Tortoise and the user. Mostly, if it's a bug from Galapagos, then it's some sort of user interface/display issue. We tend to see far more errors in the actual computations of model states (a la Tortoise), and that's why a lot of tickets get moved over there. But, anyway, it really is no big deal to me to be moving issues, and I don't expect other people to accurately predict ahead of time where one should go. Thank you for your reports, regardless of which repos they end up in. |
Reproducible by going to
https://www.netlogoweb.org/web?https://m4a-gae.appspot.com/p/SJKz6u-2ciF8Za5hYlWI4f.nlogo
And entering in the command center:
random-seed 1
Click setup
Click go
At tick 275 I get
agent.getCoords is not a function
Note that the executable has a more reasonable error (though it provides no help localising the bad code):
DISTANCE expected input to be an agent but got the number 0 instead.
org.nlogo.nvm.ArgumentTypeException: DISTANCE expected input to be an agent but got the number 0 instead.
