# Multiplayer Considerations

> fully replicates:

### **Replication**

`EquipmentComponent` fully replicates:

* Equipped items array
* Visual updates

### **Authority**

All equipment changes are validated on the server. Client calls automatically forward to the server via RPC:

```
UFUNCTION(Server, Reliable)
void Server_EquipItem(FItemInstance Item, int32 SlotIndex);

UFUNCTION(Server, Reliable)
void Server_UnequipItem(int32 SlotIndex);
```

### **Visual Updates**

Visuals rebuild from the replicated `EquippedItems` array on each client automatically via `OnRep_EquippedItems`. If visuals are out of sync, call:

```
UFUNCTION(NetMulticast, Reliable)
void Multicast_UpdateVisuals(int32 SlotIndex);
```

### Multiplayer Helper Functions

```
bool bIsServer   = EquipmentComponent->IsAuthority();    // True if running on server
bool bIsLocal    = EquipmentComponent->IsLocalPlayer();  // True if local player's equipment
```

Use `IsLocalPlayer()` to skip cosmetic-only visual work on simulated proxies.

### Debugging

```
// Call in PIE to print full equipment state to the Output Log
EquipmentComponent->PrintDebugState();
```

`PrintDebugState` is also a CallInEditor button on the component — click it while PIE is paused to diagnose visual sync issues without writing any code.
