Welcome to Dangerous Big Pickups!
Downloading the mod and running the game with the mod installed should generate a config file in BepInEx/plugins/[Your Rundown]/Custom/DangerousBigPickups.
From there you can use the template below to create an awful experience for all those involved!
Note: Negative values DO work if you want to instead be nice and give Health/Disinfection.
[ { "BigPickupId": 0, //ID from the ItemDataBlock "InfectionPerSec": 0.0, //How much infection is applied per second (float) "DamagePerSec": 0.0, //How much damage is applied per second (float) "PickupDoesDamage": false, //Does the item do damage? "PickupDoesInfection": false, //Does the item give infection? "InternalEnabled": false, //Is this block enabled? "DebugName": "Example1" }, { "BigPickupId": 0, "InfectionPerSec": 0.0, "DamagePerSec": 0.0, "PickupDoesDamage": false, "PickupDoesInfection": false, "InternalEnabled": false, "DebugName": "Example2" } ]
