Place loot spawn points and loot tables

Loot is not placed by hand. You place BP_LootSpawnPoint actors, give each one a loot table, and every run the point rolls a chance and picks an item from its table. By the end of this page you have points in your level and a table of your own.

  • The spawn point: Content/MPFriendslop/Blueprints/Environments/Spawners/BP_LootSpawnPoint
  • The tables: Blueprints/DataAssets/LootTable/Childs/
  • The loot actors they pick from: Blueprints/Environments/Loot/Childs/

Place a spawn point

  1. Drag BP_LootSpawnPoint into your level.
  2. Put it where the item should rest: on the floor, or just above a shelf plank. The arrow is hidden in game.
  3. In the Details panel, under Settings|Spawn, set Loot Table.
  4. Adjust the other fields if needed.

When the run starts, the point rolls Spawn Chance, picks an item from the table, and moves it straight down onto the first surface under it. The item is set down. It never falls, so it never starts the run damaged.

Field What it does Default
Loot Table The table this point rolls. Empty means the point spawns nothing empty
Spawn Chance Chance from 0 to 1 that this point spawns anything this run 0.6
Random Yaw Turns the item to a random direction. Untick it to use the point's own rotation ticked
Settle Trace Height How far above the item's centre, in cm, the search for a surface starts 25
Ground Trace Distance How far down, in cm, it looks for a surface 200

Every field is set per placed point. Changing a default on the class does not change a point where you already edited that field.

In the rooms of Maps/Modules/, most points use DA_LootTable_Shelf. Each dead end also has points on DA_LootTable_Salvage, the table with the heavy pieces, the bat and the hammer.

Make a loot table

  1. In Blueprints/DataAssets/LootTable/Childs/, right click, then Miscellaneous, then Data Asset.
  2. Pick BP_LootTableDataAsset. Name it DA_LootTable_<Name>.
  3. Open it and add rows to Entries.
  4. For each row, set Loot Class and Weight.
  5. Set it as the Loot Table of the points that should use it.
Field What it does
Loot Class The actor to spawn. Usually one of the BP_Loot_* classes
Weight How often this row is picked. 3 is three times as likely as 1. 0 never spawns

The easiest start is to duplicate DA_LootTable_Salvage and edit the weights. DA_LootTable_Shelf is the same list without BP_Loot_EngineBlock, BP_Loot_Generator and BP_Loot_VaultPlate: heavy items are kept off shelves. BP_Loot_BaseballBat and BP_Loot_Hammer are in no table. They are placed by hand.

Loot Class accepts any actor. To be worth money when sold, it needs a BP_LootValueComponent: see Add a loot item.

The pick is the function PickLootClass on the table. For another rule (no duplicates, a guaranteed item), make a child of BP_LootTableDataAsset and override it.

Next: Place an extraction point.
