What Manages Variables?

Zing

What should manage variables used by multiple things? Take for instance, in Mario Bros (Not a Godot game, but it is an easy example), when Mario hits a power-up block, a mushroom will spawn, then when Mario collects the mushroom he gets 100 points. What manages the score and the spawn of the mushroom? Should the mushroom itself go "I've been collected, add 100 points to the score, then disappear" or should some other script manage this sort of thing? I know that Autoloads exist, but I don't know if this is the time to use them or not.

This would be a perfect use for Autoloads. The score would be considered a global variable, so using a global script to store it would make sense.

Should the mushroom itself go "I've been collected, add 100 points to the score, then disappear" or should some other script manage this sort of thing?

The former case. The mushroom can surely add to the score and free itself no problem.

I personally would make the mushroom itself add the points to the score, because that allows you to decouple the mushroom from the rest of the code. By doing this, you would be able to delete the mushroom scene from the project without any consequences. If another script handles adding the mushroom's points, then that script has to know about the mushroom, which could cause errors if you wanted to delete the mushroom for whatever reason.
