What is the NPC Programming Extender?

This mod adds new functionality to NPC Owned drones. The guide below contains some pre-scripted methods that can easily be added to your NPC scripts to expand their functionality.

Can Target Fly

Description

This method will check the grid of the provided entity ID to see if it is capable of flight. This does a check for gyros, thrust in each direction, and a ship controller.

Global Variables Required

None.

Method Arguments

long entityId //This is the EntityId that you want to get the Coordinates of.

Method Script

bool CanTargetFly(long entityId){ try{ Me.CustomData = entityId.ToString(); return Me.GetValue<bool>("NpcExtender-TargetCanFly"); }catch(Exception exc){ return false; } }

Change Grid Ownership To New Faction

Description

This method will change ownership of the grid and any sub-grids attached. Ownership is changed by specifying a Faction Tag in the Global Variable section of your script. Once this method is run, it's best to stop the script from processing any further since it will automatically be recompiled (required after an ownership change).

Global Variables Required

string factionTag = "SPRT"; //Replace With Desired Faction Tag

Method Arguments

None.

Method Script

bool ChangeNPCFaction(){ try{ Me.CustomData = factionTag; return Me.GetValue<bool>("NpcExtender-ChangeFactionRequest"); }catch(Exception exc){ return false; } }

Chat to Players

Description

This method allows the NPC to send a message to players using the in game chat interface. The message will display for any player within the range of the NPCs active antenna. If the NPC does not have an active antenna, the message will not display for any player. It is also possible to specify the name of a custom audio clip that will play along with the chat message (not required).

Global Variables Required

Please ensure you have the following global variable(s) in your script:

string lastChatSent = "Default"

Method Arguments

string message //This is the message that is sent via chat string author //This is the name of the 'sender' that appears with the chat message string audioClip //This is the SubtypeId of the audio definition you want played with the message

Method Script

bool SendChatMessage(string message, string author, string audioClip = ""){ if(message == lastChatSent){ return false; } lastChatSent = message; double broadcastDistance = 0; var antennaList = new List<IMyRadioAntenna>(); GridTerminalSystem.GetBlocksOfType<IMyRadioAntenna>(antennaList); foreach(var antenna in antennaList){ if(antenna.IsFunctional == false || antenna.Enabled == false || antenna.EnableBroadcasting == false){ continue; } var antennaRange = (double)antenna.Radius; if(antennaRange > broadcastDistance){ broadcastDistance = antennaRange; } } if(broadcastDistance == 0){ return false; } try{ string sendData = message + "\n" + author + "\n" + broadcastDistance.ToString() + "\n" + audioClip; Me.CustomData = sendData; return Me.GetValue<bool>("NpcExtender-ChatToPlayers"); }catch(Exception exc){ return false; } }

Check NPC Ownership

Description

This method will check if the programmable block calling it is part of an NPC faction. Valid NPC factions must not have human players as members and cannot be set to Accept Humans. If the block belongs to a valid NPC, the method will return true, otherwise it will return false. If you want to check ownership by a specific NPC faction, you can provide the faction tag in the method argument.

Global Variables Required

None.

Method Arguments

string faction //If provided with a faction tag, the method will only check ownershi by that faction. If left blank, it will check ownership against any valid NPC faction

Method Script

bool CheckIfNPC(string faction = ""){ try{ if(faction == ""){ return Me.GetValue<bool>("NpcExtender-IsOwnedByNPC"); }else{ Me.CustomData = faction; return Me.GetValue<bool>("NpcExtender-IsOwnedByFaction"); } }catch(Exception exc){ return false; } }

Create Items In Block Inventory

Description

This method allows you to create an add inventory items to any block on the NPC grid. This could be used to replenish ammo or uranium, or any other use you can think of.

Accepted Examples Below: //MyObjectBuilder_Ore //MyObjectBuilder_Ingot //MyObjectBuilder_Component //MyObjectBuilder_AmmoMagazine //MyObjectBuilder_PhysicalGunObject //MyObjectBuilder_OxygenContainerObject //MyObjectBuilder_GasContainerObject string subtype //This should be the subtype of the item you want to produce float amount //This should be the amount of the item you want to produce long blockEntityId //This should be the entity ID of the block you want to add the produced item(s) to.

Method Script

bool CreateItemInBlockInventory(string type, string subtype, float amount, long blockEntityId){ Me.CustomData = type + "\n" + subtype + "\n" + amount.ToString() + "\n" + blockEntityId.ToString(); try{ return Me.GetValue<bool>("NpcExtender-CreateItemInInventory"); }catch(Exception exc){ return false; } }

Create Particle Effect

Description

This method allows the NPC to create a particle effect at a set of coordinate or attach it to the coordinates of a specific entity.

Global Variables Required

None.

Method Arguments

string effectName //This should be the SubtypeId of the particle effect you want to create. Vector3D effectCoords //These are the coordinates of where the particle effect should be created. long effectEntityId //If an entity ID is provided, its position will be used instead of the effectCoords value (set effectCoords to equal -new Vector3D(0,0,0)-).

Method Script

bool CreateParticleEffect(string effectName, Vector3D effectCoords, long effectEntityId = 0){ Me.CustomData = "ParticleEffectRequest\n" + effectName + "\n"; if(effectEntityId != 0){ Me.CustomData += effectEntityId.ToString(); }else{ Me.CustomData += effectCoords.ToString(); } try{ return Me.GetValue<bool>("NpcExtender-PlayParticleEffect"); }catch(Exception exc){ Echo("Hard Fail NpcExtender-PlayParticleEffect"); Echo(exc.ToString()); return false; } }

Ah, perfect, thanks!

Meridius_IX / Lucas [készítő] 2018. aug. 20., 15:28

If you'd like, feel free to crack open the Reavers mod or the Attack of the Uncooperative Drones mod - both of these mods use it to switch to a custom faction.

Thomas Jefferson 2018. aug. 20., 3:02

No matter what I try, I cannot get the faction change script to function properly. Is there a complete example of it being used in an actual in-game script?

Aggelus 2018. jún. 15., 9:31

Thanks for the reply.
So I believe that the only way to put a ship into a faction created by the user, would be to edit it manually inside a map for the faction created "NURS" to export it to Blueprints and then to correct the SBC.
And then she would be the faction I want.
I thought there would be some code inside the .SBC that would indicate the faction but did not find.

Meridius_IX / Lucas [készítő] 2018. jún. 15., 7:38

These methods wouldn't be used in the Scripts folder. They're setup to be added to programmable block scripts. At some point in the near future, I'll be transitioning this guide to GitHub GIST, since it seems copying code from steam guides created sloppy formatting.

Once everything is tidied up, I'll be posting some example scripts for stuff like changing factions.

Aggelus 2018. jún. 15., 6:56

I am building a MOD and wanted all the ships belonging to the NURS faction, I have already created the Factions.sbc in the DATA folder and already have the ships in the Prefabs folder along with the PirateAntennas.sbc and SpawnGroups.sbc plus they appear as pirates.
How would I create a CS that placed in the Scripts folder solved this problem?

Blacky Watchy 2018. jún. 5., 11:34

what do I must to put in "Exeption"?
