Module:Container loot

This module spits out the loot of a specific container. If it has multiple tiers the output will be tabbed. The output is not sorted - this is not possible.

Parameters

Must always call the main function. The second argument must be name of a container that is found in [[Module:Item spawns/containerData.json]

Example

{{#invoke:Container loot|main|Ammo Box}}
