How to remove a deleted Object from an Array?

Question

Set-Up: I have two classes

  • CollectableComponent which is every “coin” tutorial you’ve seen, nothing should be surprising here. Important to not is that this class, for reusability reasons, also handles what happens when a collectable gets collected. Including freeing itself.
  • VacuumCollectable which “sucks in” all CollectableComponent’s within range. I’ve included a screenshot of the classes code below since this is where my problems are arising

The Problem I’m running into is, since CollectableComponent handles freeing itself, how can I remove its reference in VacuumCollectable.collectables_in_range? I know Godot doesn’t support deleting objects while iterating through an array, but I have to do something otherwise I get a memory leak. Moreover, if possible I’d also prefer it if this can be handled inside of VacuumCollectable itself since I don’t want the 2 classes coupled like that.

If anyone could please help me out that would be greatly appreciated.

Turn off your physics process before you clear the data.

3

your area can already query what objects are overlapping, maybe you should use $Area.get_overlapping_areas() instead of managing your own collectables_in_range?

4

Collectable should send a signal right before it gets deleted, passing a reference to self as the signal argument. The object that holds the list should then receive this signal and remove the reference from the array.

You can also just use a scene tree group instead of maintaining a custom array.

I forgot about get_overlapping_areas(). that solution worked perfectly, thank you!
