Infinite Water Generation Exploit via Farm Plots (Vanilla)

Sardaukai shared this bug ago

Reported

A reproducible exploit has been found in the vanilla game that allows a player to generate an infinite source of water using the standard Farm Plot block. This behavior occurs because the farm plot retains its "watered".

Start a vanilla game (e.g., with the 'Food' option enabled).
Place multiple Farm Plots, one Irrigation System, and a Power Source.
Setup: Disable all blocks except the Power Source. Set the first Farm Plot to On.
Fill the Irrigation System with Ice (to generate water), and fully irrigate the first plot.
Test Start: Once the first plot is full, turn off the Irrigation System.
Turn on the remaining Farm Plots, ensuring their Stockpile option is enabled.
Observed Result: Check the water level at the first plot. No changes occur to the water level, despite the other plots being turned on and potentially requiring water for stockpiling.

EDIT: I also deleted the IrrigationSystem later and get infinity water the FarmPlot.

To prove this, I recorded a short clip demonstrating the issue in a controlled vanilla environment. The link is provided below

I also used this code to get sure

[MyEntityComponentDescriptor(typeof(MyObjectBuilder_FunctionalBlock), useEntityUpdate: true)]
 public class StockpileEnforcerLogic : MyGameLogicComponent
 {
     private bool m_isServer;
     IMyFarmPlotLogic _planterComponent;
     IMyResourceStorageComponent _storageComponent;
     public override void Init(MyObjectBuilder_EntityBase objectBuilder)
     {
         base.Init(objectBuilder);
         m_isServer = MyAPIGateway.Multiplayer.IsServer;

         var block = Entity as IMyFunctionalBlock;

         if (block == null)
             return;

         foreach (var component in block.Components)
         {
             _planterComponent = component as IMyFarmPlotLogic;
             if (_planterComponent != null)
                 break;
         }

         foreach (var component in block.Components)
         {
             _storageComponent = component as IMyResourceStorageComponent;
             if (_storageComponent != null)
                 break;
         }

         if (_planterComponent == null)
             return;

         if (m_isServer)
         {
             NeedsUpdate = MyEntityUpdateEnum.EACH_100TH_FRAME;
         }
     }

     public override void UpdateBeforeSimulation100()
     {
         MyLog.Default.WriteLine(Entity.Name + " FilledRatio " + _storageComponent.FilledRatio);
         MyLog.Default.WriteLine(Entity.Name + " ResourceCapacity " + _storageComponent.ResourceCapacity);
     }
 }

Started game, created two farms, an irrigation system and a battery.

105852584650738532 is the first farm I filled with water

74882667097017340 was off.

I deleted the irrigation system!

The grid consists of two farms, two conveyors, and a battery.

Both farms full, no drain from Farm 105852584650738532

I also used this code to get sure

[MyEntityComponentDescriptor(typeof(MyObjectBuilder_FunctionalBlock), useEntityUpdate: true)]
 public class StockpileEnforcerLogic : MyGameLogicComponent
 {
     private bool m_isServer;
     IMyFarmPlotLogic _planterComponent;
     IMyResourceStorageComponent _storageComponent;
     public override void Init(MyObjectBuilder_EntityBase objectBuilder)
     {
         base.Init(objectBuilder);
         m_isServer = MyAPIGateway.Multiplayer.IsServer;

         var block = Entity as IMyFunctionalBlock;

         if (block == null)
             return;

         foreach (var component in block.Components)
         {
             _planterComponent = component as IMyFarmPlotLogic;
             if (_planterComponent != null)
                 break;
         }

         foreach (var component in block.Components)
         {
             _storageComponent = component as IMyResourceStorageComponent;
             if (_storageComponent != null)
                 break;
         }

         if (_planterComponent == null)
             return;

         if (m_isServer)
         {
             NeedsUpdate = MyEntityUpdateEnum.EACH_100TH_FRAME;
         }
     }

     public override void UpdateBeforeSimulation100()
     {
         MyLog.Default.WriteLine(Entity.Name + " FilledRatio " + _storageComponent.FilledRatio);
         MyLog.Default.WriteLine(Entity.Name + " ResourceCapacity " + _storageComponent.ResourceCapacity);
     }
 }
