UMI’s Loot System can optionally integrate with the Respawn Manager to support respawnable loot sources, such as:
  • Resource nodes (trees, rocks, ore veins)
  • World chests that refill over time
  • Enemy containers or destructibles that respawn
  • Any loot-bearing actor that reappears after a delay
This is not required to use the Loot System, but it provides a clean and consistent way to handle timed resets.

​
Basic Pattern: Register Respawn Request

Whenever a loot source is harvested or opened:
  1. Generate loot
  2. Mark the actor as depleted
  3. Hide/disable interaction
  4. Register the actor with the Respawn Manager

​
Blueprint Example

Event OnLootCollected
   ↓
Set bHasBeenLooted = true
LootComponent → Generate Loot
Disable interaction
Hide chest / resource mesh
   ↓
Get RespawnManagerSubsystem
   → Register Respawn Request
        Target Actor = Self
        Delay        = RespawnTime

​
C++ Example

void ALootActor::OnLootCollected(APlayerController* Player)
{
    if (bHasBeenLooted) return;
    bHasBeenLooted = true;

    // Generate loot
    FLootResult Result = LootComponent->GenerateLoot();
    GiveLootToPlayer(Player, Result);

    // Hide or disable actor
    Mesh->SetVisibility(false);
    Mesh->SetCollisionEnabled(ECollisionEnabled::NoCollision);

    // Register respawn request
    if (URespawnManagerSubsystem* RM = GetWorld()->GetSubsystem<URespawnManagerSubsystem>())
    {
        RM->RegisterRespawnRequest(this, RespawnTime);
    }
}

​
On Respawn (Blueprint or C++)

Actors using Respawn Manager should implement BPI_Respawnable (BP) or IRespawnable (C++).

​
Blueprint

Event OnRespawnRequested
   ↓
Set bHasBeenLooted = false
LootComponent → Reset Loot
Show mesh
Enable collision
Enable interaction

​
C++ (interface implementation)

void ALootActor::OnRespawnRequested()
{
    bHasBeenLooted = false;

    if (LootComponent)
        LootComponent->ResetLoot();

    Mesh->SetVisibility(true);
    Mesh->SetCollisionEnabled(ECollisionEnabled::QueryAndPhysics);
}
Use Respawn Manager with loot when you need:

​
✔ Respawning World Loot

Examples: berry bushes, mushrooms, herbs, mineral nodes.

​
✔ Refillable Chests / Supply Caches

Chests that regenerate loot after X minutes/hours.

​
✔ Dungeons / Camps / Static Sites

Simple timed resets without building full encounter logic.

​
✔ Farming Gameplay

Resource loops where players gather materials from renewable nodes.
