I spent at least 30 minutes trying to figure out why the score in my game wasn’t updating past the first point. It would go from 0 to 1, but then stayed at 1. I had a setter on the score variable, to update the score label shown to the user whenever the score changed.

It turned out, my setter wasn’t actually setting, so to score was always zero, and the incoming new score was always 1.

The missing line in the “set” code below is SCORE=new_score

some gdscript code that sets a text label when a variable is changed (but neglects to actually store the new value)
