Place a revive bay

A dead player can come back while their head still exists. A teammate carries the head to a revive bay, drops it in the cradle, and holds the interact key. The player is rebuilt standing in front of the machine. By the end of this page you have a bay in your level, and you know how to make your own remains work with it.

  • The bay: Content/MPFriendslop/Blueprints/Environments/Fixtures/BP_ReviveBay
  • Its sign: Blueprints/Widgets/World/WBP_ReviveSign
  • The two interfaces it talks through: Blueprints/Interfaces/BPI_PlayerRemains and BPI_Revivable

How the bay decides

The server scans the bay's CradleZone every Detection Interval. When it finds a head whose owner is still down, it snaps the head into HeadSlot and the bay becomes Loaded. The bay's status is an E_ReviveStatus, and the sign shows it.

Status When Sign
Empty No head in the cradle Bring a head here
Loaded A head is snapped in. A player can now hold interact Hold to rebuild
Working The player was just rebuilt. The clamps and the scanner play their animation for Cycle Duration REBUILDING...

The player is rebuilt the moment the hold completes, at the start of Working. The cycle that follows is only the animation, then the bay goes back to Empty.

A revive only works during the bleedout. When Bleedout Seconds runs out, the head is destroyed and there is nothing left to bring back. That timer and the health given back (Revive Health) live on the player's BP_DeathComponent. See Death, revive and the spectator.

Place the bay

  1. Drag BP_ReviveBay into the level.
  2. Leave free floor in front of it. The revived player appears at the ExitPoint component.
  3. If you move the bay against a wall or change its shape, select ExitPoint, HeadSlot or CradleZone in the Components panel and move them to match.

The bay is ready. It needs no link to a door, a button or a spawn point.

Component What it does
CradleZone The box that finds a head dropped in the bay
HeadSlot Where the head is held while the bay is Loaded
ExitPoint Where the revived player appears
Display Draws WBP_ReviveSign
JawLeft, JawRight, Gantry The clamps and the scanner that move during Working

The fields

All of them are on the placed BP_ReviveBay.

Field Category What it does Default
Prompt Settings|Interaction The text of the interaction prompt Rebuild
Type Settings|Interaction How the player interacts Hold
Duration Settings|Interaction Seconds to hold 1.5
Detection Interval Settings|Revive Seconds between two scans of CradleZone 0.2
Detection Object Types Settings|Revive The collision object types the scan looks for WorldDynamic, Pawn, PhysicsBody
Cycle Duration Settings|Revive Seconds of the clamp and scanner animation after a rebuild 5
Jaw Stroke Settings|Revive How far each clamp moves, in cm 8
Gantry Drop Settings|Revive How far the scanner moves, in cm -10

The sign's texts and colours are on WBP_ReviveSign: Empty Text, Loaded Text, Working Text, and Empty Color, Loaded Color, Working Color. Change them in the widget to change every bay.

Your own remains

The bay does not know the head, the character or the death component. It reaches all three through interfaces, so any of them can be yours.

  1. On the actor that stands for a dead player (a corpse, a dog tag, a soul), implement BPI_PlayerRemains:
    • Get Remains Owner returns the dead player's PlayerState.
    • Snap Remains To receives the HeadSlot location and rotation. Move your actor there, stop its physics, and return Snapped true. Return false to refuse, for example while someone holds it.
  2. Give that actor a collision object type listed in the bay's Detection Object Types.
  3. Make sure the owner's PlayerState answers Get Is Down from BPI_PlayerLifeState with true while the player is dead.
  4. On a component of the dead player's pawn, implement BPI_Revivable. Revive At receives the ExitPoint location and rotation: bring the player back there and remove your remains.

BP_PlayerHead and BP_DeathComponent do exactly this. Open them for a working example.

Warning

The bay looks for BPI_Revivable on the pawn's components only. Implemented on the pawn itself, it is never found: the hold completes, the bay plays its cycle, and nobody comes back. There is no error.

The dispatchers

Dispatcher When it fires Fires on
OnStatusChanged The bay's status changed. Gives the new Status every player
