SSslimer

Now I try to use SimpleNetworkWrapper as MultiMote suggested me.

I get an error when I open my gui. In server side, again NPE Entity entity = world.getEntityByID(x);

Thanks, should I use client and server or only client side gui element?

Thanks for fast reply. I have my own GuiHandler ,but do I realy need it for my gui when it is opening from another gui?

Hi, I managed to create inventory for my mob, it is simillar to horse. But there is one problem. I dont know how to open it, I tried to use method player.displayGUIChest(), but after that my gui looks like chest.Horse gui use method: displayGUIHorse(), but I cant use it due to different entity class. What method should I use to display my gui?

Still help needed. Does anyone know what are speed values for player?

I need sth like: this.getEntityAttribute(SharedMonsterAttributes.movementSpeed).setBaseValue(0.7D); and for AI e.g this.tasks.addTask(4, new EntityAIMoveTowardsRestriction(this, 0.6D)); I cant find attribute value.For player there isnt any AI. So its a bit harder to found values.

Hey, I am trying to set speeds for my mob. What I need to know are player atribute speed, player speed value while walking and runing used in AI form. I was searching in some topics, but I could not find that values. Can someone help?

Thanks I had: Random random; and when I used rand from Entity, it works.

Hey, when my method starts mc get an error private String[] firstnames = new String[] {"a", "b", "c"}; Random random; public void setFirstName() { this.firstName = this.firstnames[this.random.nextInt(this.firstnames.length)]; } And the error: net.minecraft.util.ReportedException: Ticking memory connection at net.minecraft.network.NetworkSystem.networkTick(NetworkSystem.java:198) ~[NetworkSystem.class:?] at net.minecraft.server.MinecraftServer.updateTimeLightAndEntities(MinecraftServer.java:716) ~[MinecraftServer.class:?] at net.minecraft.server.MinecraftServer.tick(MinecraftServer.java:604) ~[MinecraftServer.class:?] at net.minecraft.server.integrated.IntegratedServer.tick(IntegratedServer.java:118) ~[integratedServer.class:?] at net.minecraft.server.MinecraftServer.run(MinecraftServer.java:482) [MinecraftServer.class:?] at net.minecraft.server.MinecraftServer$2.run(MinecraftServer.java:742) [MinecraftServer$2.class:?] Caused by: java.lang.NullPointerException at BetterWorld.mobs.EntityBetterVillager.setFirstName(EntityBetterVillager.java:260) ~[EntityBetterVillager.class:?] at BetterWorld.mobs.EntityBetterVillager.onSpawnWithEgg(EntityBetterVillager.java:378) ~[EntityBetterVillager.class:?] at net.minecraft.item.ItemMonsterPlacer.spawnCreature(ItemMonsterPlacer.java:181) ~[itemMonsterPlacer.class:?] at net.minecraft.item.ItemMonsterPlacer.onItemUse(ItemMonsterPlacer.java:79) ~[itemMonsterPlacer.class:?] at net.minecraft.item.ItemStack.tryPlaceItemIntoWorld(ItemStack.java:144) ~[itemStack.class:?] at net.minecraft.server.management.ItemInWorldManager.activateBlockOrUseItem(ItemInWorldManager.java:418) ~[itemInWorldManager.class:?] at net.minecraft.network.NetHandlerPlayServer.processPlayerBlockPlacement(NetHandlerPlayServer.java:588) ~[NetHandlerPlayServer.class:?] at net.minecraft.network.play.client.C08PacketPlayerBlockPlacement.processPacket(C08PacketPlayerBlockPlacement.java:74) ~[C08PacketPlayerBlockPlacement.class:?] at net.minecraft.network.play.client.C08PacketPlayerBlockPlacement.processPacket(C08PacketPlayerBlockPlacement.java:122) ~[C08PacketPlayerBlockPlacement.class:?] at net.minecraft.network.NetworkManager.processReceivedPackets(NetworkManager.java:232) ~[NetworkManager.class:?] at net.minecraft.network.NetworkSystem.networkTick(NetworkSystem.java:182) ~[NetworkSystem.class:?] ... 5 more

Thanks it works.

Hey, I need to find the uses of VillageCollection.addVillagerPosition() in other classes. I am using Eclipse Ctrl+F, but I have found nothing yet. Where that method can be?

No one wants to help me privately so I am passed on this topic. So, to create village nearby doors must be detected.To detect doors chunk coordinates must be gathered from villagerPositionsList Here are the methods in which coordinates are saved to list. The problem is that these methods looks like dead end.Does somebody know what must be changed or is it realy the DEAD END? I fink that I don't need any help.I changed method in which doors are detected.Now I can get cords of nearest villages, so my code works Thanks for good help and time spent to help with my project.Today I corect few things and in my GUI I can see info about village.Now my target is to search what makes strange lags and embark on with project.

My GUI works fine.Doing tests I have noticed that village can't create, that's why in GUI is only 0. Searching more I have found that villageList = 0 and here is my question. Does enybody know why despite Vanilla code there is so much problems with village? I am stuck with some strange problem with villagerPositionsList, maybe because it's a black hole. In that stage I need to fine some person who knows about village code everything or very much.

I made TickHandler and now my village tick() as it should.Now I am sure that sth is wrong with doors. The size of doorslist is 0. Do you know why my code needs some changes despite it is the same as Vanilla?

Zombie break only wooden door and to make them break custom door you will need to edit zobies ai and some code in other classes.

I have own projectile too and the problem is the same. I read is some topic that it's forge bug or sth similar. I read also that this problem can be fixed, by mod maker, but it's hard.

I have fixed the error. Now I can open my GUI without crash but still sth doesn't work because despite my block is in center of some village, no stats shows in gui. Now I am trying to find the wrong code, probably sth is wrong with searching doors. Searching for a long time I have noticed that Vanilla village has additional code in the WorldServer.class public void tick() { ... this.theProfiler.endStartSection("village"); this.villageCollectionObj.tick(); ... I must try to code the second line somehow.

public class BetterWorldHandler { public BetterWorldHandler() { } public BetterVillageCollection villageCollectionObj; @SubscribeEvent public void someEventMethod(WorldEvent event) { BetterVillageCollection villagecollection = (BetterVillageCollection)event.world.perWorldStorage.loadData(BetterVillageCollection.class, "bettervillages"); if (villagecollection == null) { this.villageCollectionObj = new BetterVillageCollection(event.world); event.world.perWorldStorage.setData("bettervillages", this.villageCollectionObj); } else { this.villageCollectionObj = villagecollection; this.villageCollectionObj.func_82566_a(event.world); } } }

For now my mod is for client. The informations about nearest village player can see in my own gui. Crash report indicates that with second line of the code below something is wrong. BetterWorldHandler handler = new BetterWorldHandler(); BetterVillageCollection vlgc = handler.villageCollectionObj;

Sorry, I don't know anything about packets. You have writen "If you display things like this on the client you will need to send Packets."
