# BP_Door

**Actor** · `/Game/ScribeTest/Blueprints/BP_Door`

A door that opens when the player interacts with it.
Locked doors need their BP_Key.

## C++ migration

**Consider C++** (score 34 of 100)

- Event Tick runs 24 nodes every frame; a C++ Tick, a timer or an event costs far less.

Before an engine upgrade:

- 1 deprecated node: replace it before the next engine upgrade.
- Compiles with warnings: today's warnings are often the next version's errors.

## Audit

- **Warning** · Event Tick: Event Tick runs 24 nodes every frame. Timers, events or a lower tick interval are often cheaper.
- **Info** · Cast to Blueprint: Casts to BP_Key. The cast target is loaded together with this Blueprint; an interface avoids that.
- **Info** · Unused variable: Variable 'Settings' is not used in any graph of this Blueprint (other Blueprints may still use it).
- **Info** · Unused variable: Variable 'State' is not used in any graph of this Blueprint (other Blueprints may still use it).
- **Warning** · Unused variable: Private variable 'UnusedCounter' is not used in any graph.
- **Warning** · Dead nodes: 1 node in 'EventGraph' never runs because nothing is connected to the exec input: Print String.
- **Info** · Unused results: 1 pure node in 'EventGraph' has no connected output: Get Actor Location.
- **Info** · Disabled nodes: 1 disabled node in 'EventGraph': Print String.
- **Warning** · Deprecated node: 'Get Unique Device Id' in 'EventGraph' is deprecated: Usage of 'Get Unique Device Id' has been deprecated. Use GetDeviceId instead
- **Info** · Missing description: 2 functions and events have no description: HelperNoDocs, Slam.
- **Info** · Missing description: 1 public variable has no tooltip: OpenSpeed.
- **Warning** · Circular reference: Hard reference cycle with BP_Key. Each of them loads all the others; an interface or a soft reference breaks the cycle.
