c# Zombie spawner

Good evening,

I have a problem with the zombie spawner here.

I go through this loop every 30 minutes,

spawning a zombie, it also works until there is a mistake.

What could be the reason ?

Here is the code excerpt:

Code:

private static void Spawn(Vector3 _pos, int _rotation){
foreach (KeyValuePair&lt;string, int&gt; kvp in test)
{
	var random = new System.Random();
	int index = random.Next(z_namenlist.Count);
	string z_name = z_namenlist[index];
	string name = z_name;
	Entity Spawn_zombie = EntityFactory.CreateEntity(EntityClass.FromString(name), _pos);
	Vector3 vec = Spawn_zombie.rotation;
	vec.y = _rotation;
	Spawn_zombie.SetRotation(vec);
	Spawn_zombie.SetPosition(_pos);
	GameManager.Instance.World.SpawnEntityInWorld(Spawn_zombie);
}
}

Here the error from the log:

Receiving unhandled NULL exception#0 0x007fd15059b780 in _L_unlock_13

#1 0x007fd15059be10 in physx::Cm::CmEventNameProvider::~CmEventNameProvider()

Schِnen guten Abend,

ich habe hier ein Problem beim Zombie spawner.

Ich durchlaufe alle 30 Minuten diese schleife,

um ein ein Zombie spawnen, dies funktioniert auch, bis es ein Fehler gibt.

An was kann das liegen ?

Code siehe oben.

Who can help me ?

Thanks for PMing me about your code. I wish I could help but beyond simple xml edits I am useless. Hopefully someone else around here will be able to help you.

Look at the spawnvehicle item class or SpawnEntity block class in the DLL.

Both can be used to spawn entities. They might help you identify the problem.

Google Translate Deutsche.

Schauen Sie sich die Spawnvehicle-Elementklasse oder die SpawnEntity-Blockklasse in der DLL an.

Beide kِnnen verwendet werden, um Entitنten zu erzeugen. Sie kِnnen Ihnen helfen, das Problem zu identifizieren.

That works so far,

after about 10 passes this error comes as written above.

I have tried and tested a lot but the error keeps coming back.

Here is my whole script with the loop.

Code:

        public static void Auto_spawn()

               }
           }
       }

Maybe move yuor SdtdConsole.instance.ExecuteSync() outside of all your loops? I am not sure what that does. I have not used it.

Maybe also set spawner type?

Code:

           spawnEntity.SetSpawnerSource(EnumSpawnerSource.Dynamic);
           world.SpawnEntityInWorld(spawnEntity);

The SdtdConsole.instance.ExecuteSync () was just a test, I removed that.

I have now tested several things and again after several times through the loop he has brought me this mistake.

I then tested everything and checked it line by line,

as soon as I add this line:

Code:

Entity spawnEntity = EntityFactory.CreateEntity(entityID, vector3_block_pos);

, the error comes.

Here is my New code:

Code:

                    foreach (KeyValuePair&lt;string, int&gt; kvp in pos)
                   {

                       int.TryParse(block_pos[1], out int pos_y);
                       int.TryParse(block_pos[2], out int pos_z);

                       var vector3_pos = new Vector3((float)pos_x, (float)pos_y, (float)pos_z);

                       World world = GameManager.Instance.World;
                       int entityID = EntityGroups.GetRandomFromGroup("Z_Spawner");

                       if (entityID &gt; 0)
                       {
                           Entity spawnEntity = EntityFactory.CreateEntity(entityID, vector3_pos);
                           spawnEntity.SetSpawnerSource(EnumSpawnerSource.Dynamic);
                           world.SpawnEntityInWorld(spawnEntity);

I would suggest printing out using Debug.Log() the values of the vector3_pos and the entityID you are getting. Maybe a pattern will emerge.

Check the KVP key to see if it's null when looping.

You shouldn't sleep the main thread as that will freeze your whole game and you may be getting physics errors because of the time jumps.

If this isn't the main thread that could be the problem and you're getting cross-threading issues.

Use an coroutine if you want to delay the spawn or something that tracks the time on each frame.

I posted an example a while ago: https://7daystodie.com/forums/showthread.php?40959

I tested everything and all the values have an entry,

I have also tested their function and run multiple times

the same error has come.

On the stable 16.4 is my option working fine, not on this stable.

I'll give you the 2 functions that are responsible.

The Timer class this is calling all:

Code:

using System.Timers;

namespace test
{
   class Class1
   {
       private static bool timer1Running = false;

       private static System.Timers.Timer t1 = new System.Timers.Timer();
       public static int z_spawn = 0;

       public static void Timer_Start()
       {
           if (!timer1Running)
           {
               timer1Running = true;
               t1.Interval = 1000;
               t1.Start();
               t1.Elapsed += new ElapsedEventHandler(Init);
           }
       }


       public static void Init(object sender, ElapsedEventArgs e)
       {
           if (Spawner.IsEnabled)
           {
               z_spawn++;
               if (z_spawn &gt;= 15) //if (_auto_block_spawner &gt;= Auto_Block_spawner * 60)
               {
                   z_spawn = 0;
                   if (!Spawner.auto_laeuft)
                   {
                       //Spawner.Auto_spawn();

                       GameManager.Instance.StartCoroutine(Spawner.StartSpawn());
                   }
               }
           }
           else
           {
               z_spawn = 0;
           }

       }
   }
}

If I run

Code:

GameManager.Instance.StartCoroutine(Spawner.StartSpawn());

via a chat command or something, then the spawn will run without an error, but if I do this over the timer then the error will come after a while. How can I solve this ?

I test it now over 4 hours, without result.

Can someone help me ?

HAL9000 · Apr 21, 2019

Where are you starting the timer? If the code runs without error if run from a console command then it sounds like the problem is in the other code not listed here.

cookyman · Apr 21, 2019

I start because of this timer:

Code:

public void GameAwake()
{
Timers.TimerStart();
}

Here The timer class:

Code:

using System.Timers;

namespace test
{
   class Timers
   {
       private static bool timer1Running = false;

       private static System.Timers.Timer t1 = new System.Timers.Timer();
       public static int z_spawn = 0;

       public static void Timer_Start()
       {
           if (!timer1Running)
           {
               timer1Running = true;
               t1.Interval = 1000;
               t1.Start();
               t1.Elapsed += new ElapsedEventHandler(Init);
           }
       }


       public static void Init(object sender, ElapsedEventArgs e)
       {
           if (Spawner.IsEnabled)
           {
               z_spawn++;
               if (z_spawn &gt;= 15) //if (_auto_block_spawner &gt;= Auto_Block_spawner * 60)
               {
                   z_spawn = 0;
                   if (!Spawner.auto_laeuft)
                   {
                       //Spawner.Auto_spawn();

                       GameManager.Instance.StartCoroutine(Spawner.StartSpawn());
                   }
               }
           }
           else
           {
               z_spawn = 0;
           }

       }
   }
}

The rest of the code in the timer works perfectly,

only spawn that.

This is a .dll file like this one.

HAL9000 · Apr 21, 2019

I'd get rid of the timer object. I'm not sure how Mono handles it but I'm pretty sure you'll be cross-threading the call into the spawn routine which could cause issues.

You can use the coroutine I posted above to be a timer as well. Using the yield return WaitForSeconds() causes that code to pause for the time specified without stopping the whole thread.

EntityFactory.CreateEntity can not be run in a subthread

Is this for an api mod?

When adding spawns you can add them to a Queue list, this can be the subthreaded part

In the GameUpdate I checks if certain conditions are met like enough time since the last run has passed so it doesnt deadlock the main thread trying to process spawns

If the conditions are met and a spawn is required it then calls the CreateEntity in the main thread using the spawn data created previously

some code samples:

Code:

   private static void GameStartDone()
   {
     IsAwake = true;
   }

   private static void GameUpdate()
   {
     if (IsAwake)
     {
       EntitySpawner.ProcessSpawnQueue();
     }
   }

Code:

           EntitySpawner.SpawnQueue.Enqueue(new Spawn
           {
             EntityClassId = classId, // "EntityClassName".GetHashCode();
             SpawnPos = position,
             TargetPos = position
           });

Code:

 class EntitySpawner {
   public static readonly Queue&lt;Spawn&gt; SpawnQueue = new Queue&lt;Spawn&gt;();
   private static long _lastTick;

   public void ProcessSpawnQueue()
   {
     // 10,000,000 ticks per second
     if (DateTime.UtcNow.Ticks &lt;= _lastTick + 500000L) { return; }

     _lastTick = DateTime.UtcNow.Ticks;
     if (SpawnQueue.Count == 0) { return; }

     lock (SpawnQueue)
     {
       var sw = new MicroStopwatch();
       for (; SpawnQueue.Count &gt; 0 && sw.ElapsedTicks &lt; 250000L;)
       {
         try
         {
           //if obey maxspawns use below
           //if (GameStats.GetInt(EnumGameStats.EnemyCount) &gt;= GamePrefs.GetInt(EnumGamePrefs.MaxSpawnedZombies)) return;

           var world = GameManager.Instance.World;
           var spawn = SpawnQueue.Dequeue();
           var pos = new Vector3(0,40,0);

             var entity = EntityFactory.CreateEntity(spawn.EntityClassId, pos) as EntityEnemy;
             if (entity == null) { continue; }

             world.Entities.Add(entity.entityId, entity);

             if (entity.IsEntityAttachedToChunk && !entity.addedToChunk)
             {
               var chunk = world.GetChunkFromWorldPos(entity.GetBlockPosition()) as Chunk;
               chunk?.AddEntityToChunk(entity);
             }
             world.audioManager?.EntityAddedToWorld(entity, world);
             world.entityDistributer.Add(entity);
             entity.Spawned = true;
             world.aiDirector.AddEntity(entity);
             entity.SetInvestigatePosition(new Vector3(spawn.TargetPos.x, spawn.TargetPos.y, spawn.TargetPos.z), 6000);
         }
         catch (Exception e)
         {
           Log.Out($"Error in {GetType().Name}.{MethodBase.GetCurrentMethod().Name}: {e}");
         }
       }
       sw.Stop();
     }
   }
 }

@ HAL9000

You mean that I create an endless loop,

which then always stop with yield return WaitForSeconds()?

Example:

Code:

object wait_2 = new WaitForSeconds(2);
while (true)
{
yield return wait_2;
}

@StompyNZ

Yes this is for a api mod.

Thanks, I will test it and then get back to you.

HAL9000 · Apr 23, 2019

You can stop coroutines by using "yield break" or just letting the method reach the end of the code (as long as you've yielded at some point in the method). In the example in the other post it spawns 10 entities then the routine ends
