Removing certain elements from the code fixes it. For example, removing : boolean from IsFull. Also, moving IsFull to a different position in the script also fixes it, without needing to remove : boolean
I have all beta-features enabled besides the following:
This seems similar to the mostly red line you sometimes get when there is a typechecking error.
I’ve run into issues with the new type-solver having issues with and / or operators used on comparison statements, so it is possible that it is related to this issue.
Also, in this code sample, max_capacity could be nil, which could be leading to the typechecking issue.
Thank you, let’s keep an eye on this and if it doesn’t repro any more we can close it: I suspect that the new solver was updated and it fixed this problem.
Thanks for getting back to me on this.
Can you please look at the Script Analysis widget and let us know what the error is? Then, can you please disable the solver beta to see if it causes this issue?
