How to spawn the correct Blueprint from C++?

Hi gedamial,

Maybe I am misunderstanding but if the pickup is of the same class as the weapon the character is holding, you can just detach it and stop moving it, right? There would be no need to spawn a new actor. If you do need to spawn a new actor, you can do so in the Die() function by fetching the class of weapon the character was holding, and passing that as an argument into SpawnActor. Also see UObjectBase::GetClass | Unreal Engine 5.2 Documentation and UWorld::SpawnActor | Unreal Engine 5.2 Documentation. Note that it allows you to spawn an actor of a class different from the template argument.

My game has no graphics. It’s all code for now, since I’m not an artist.

The Character has an array of equipped weapons. The PickupWeapon makes the corresponding weapon in the array “usable”.

The PickupWeapon class has an enumeration EWeaponType which has to be set to the weapon type the Pickup should correspond to. (e.g. RocketLauncher, Pistol, GrenadeLauncher…) —> this value is set in the BLUEPRINT CHILD CLASS.

Once the PickupWeapon is picked up by the player, the Character’s weapon is enabled in the array (depending on the WeaponType of the PickupWeapon).

When the player dies I want to spawn the PickupWeapon… but since the PickupWeapon has many Blueprint child classes… I need a way to detect the Blueprint child class that has the WeaponType corresponding to the currently-equipped weapontype.

I hope I made it clearer…
