Disclaimer: pseudo-script follows; don’t use as is or else!:
- we have a base class and 2 children
- the player can only have 2 guns and they start with 2
- the first one is the current gun
- 1 toggles between them
- this needs attachment, hiding unhiding and whatnot; more logic for picking up / dropping actors
And if the player starts with 2 empty WeaponSlots (as you call it), how do those slots get populated with the correct weapon reference - here we circle back to the error messages: how do you SET Current Weapon. Because it’s clearly not set.
And Get / Set is this:
You can see it used with Gun / Weapon vars in the 1st pic.
There are more ways to instantiate those weapons but you’d need to detail the desirable behaviour.
