SOLVED Entité Block
-
Bonjour j’ai créé un tapi roulant permettant de faire avancer des blocks, pour faire l’entité du block qui bouge, pour l’instant je me suis basée sur celle du sable qui tombe mais j’ai un problème au niveau de rendu: au début j’utilisais le rendu du sable mais comme le vecteur de déplacement de mon entité et celui du sable sont différents, le rendu se fait mal. J’ai donc opté pour créer mon propre rendu. Cela fait que maintenant, lorsque l’entité apparais, mon minecraft crash:

EntityRegistry.registerGlobalEntityID(entityClass, entityName, entityID); EntityRegistry.registerModEntity(entityClass, entityName, entityID, ModMaxyFactory.instance, 64, 1, true);Dites moi, si c’est mieux d’utiliser un tileentity(dans ce cas il faut m’expliquer commen en utiliser un) ou comment régler le problème de crash.
-
Un tile entity ne sert à rien dans ce cas.
registerGlobalEntityID ne doit pas être utilisé.Et ton problème est un npe à la ligne 89 de EntityConvoyedBlock
-
J’ai enlevé registerGlobalEntityID.
A la ligne 89 , j’ai this.setDead(); dans un onUpdate() :
(c’est le premier this.setDead(); )public void onUpdate() { Block block = this.fallTile.getBlock(); if (block.getMaterial() == Material.air) { this.setDead(); } else { this.prevPosX = this.posX; this.prevPosY = this.posY; this.prevPosZ = this.posZ; BlockPos blockpos; if (this.fallTime++ == 0) { blockpos = new BlockPos(this); if (this.worldObj.getBlockState(blockpos).getBlock() == block) { this.worldObj.setBlockToAir(blockpos); } else if (!this.worldObj.isRemote) { this.setDead(); return; } } this.motionY -= 0.03999999910593033D; this.moveEntity(this.motionX, this.motionY, this.motionZ); this.motionY *= 0.98D; if (this.fallTime > 10) { this.motionX *= 0.98D; this.motionZ *= 0.98D; } if (!this.worldObj.isRemote) { blockpos = new BlockPos(this); if (this.fallTime > 10 && this.onGround) { this.motionX *= 0.699999988079071D; this.motionZ *= 0.699999988079071D; this.motionY *= -0.5D; if (this.worldObj.getBlockState(blockpos).getBlock() != Blocks.piston_extension) { this.setDead(); if (!this.field_145808_f && this.worldObj.canBlockBePlaced(block, blockpos, true, EnumFacing.UP, (Entity)null, (ItemStack)null) && this.worldObj.setBlockState(blockpos, this.fallTile, 3)) { if (block instanceof BlockConvoyorBelt) { ((BlockConvoyorBelt)block).onEndFalling(this.worldObj, blockpos); } if (this.tileEntityData != null && block instanceof ITileEntityProvider) { TileEntity tileentity = this.worldObj.getTileEntity(blockpos); if (tileentity != null) { NBTTagCompound nbttagcompound = new NBTTagCompound(); tileentity.writeToNBT(nbttagcompound); Iterator iterator = this.tileEntityData.getKeySet().iterator(); while (iterator.hasNext()) { String s = (String)iterator.next(); NBTBase nbtbase = this.tileEntityData.getTag(s); if (!s.equals("x") && !s.equals("y") && !s.equals("z")) { nbttagcompound.setTag(s, nbtbase.copy()); } } tileentity.readFromNBT(nbttagcompound); tileentity.markDirty(); } } } else if (this.shouldDropItem && !this.field_145808_f && this.worldObj.getGameRules().getGameRuleBooleanValue("doTileDrops")) { this.entityDropItem(new ItemStack(block, 1, block.damageDropped(this.fallTile)), 0.0F); } } } else if (this.fallTime > 100 && !this.worldObj.isRemote && (blockpos.getY() < 1 || blockpos.getY() > 256) || this.fallTime > 600) { if (this.shouldDropItem && this.worldObj.getGameRules().getGameRuleBooleanValue("doTileDrops")) { this.entityDropItem(new ItemStack(block, 1, block.damageDropped(this.fallTile)), 0.0F); } this.setDead(); } } } }Je ne comprend pas ce qui ne vas pas, puisque le this.setDead(); est censé s’exécuter si le block déplacé est de l’air, ce qui n’arrive jamais.
-
Je ne comprends pas plus que toi puisqu’un this.setDead() ne peut pas causer un npe x)
-
Ou allors c’est Block block = this.fallTile.getBlock(); qui est juste au dessus le problème mais logiquement c’est un problème de rendu puisque ça fonctionne quand je me le rendu du sable ou quand je ne met pas EntityRegistry.registerModEntity(entityClass, entityName, entityID, ModMaxyFactory.instance, 64, 1, true);
-
fallTile correspond à quoi ?
Vérifies quand même avec System.out.println(fallTile); -
fallTile est le BlockState dans lequel est enregistré les stat du block qui est en trains de se faire déplacer (je l’ai copié sur l’entity du FallingBlock)
System.out.println(fallTile); me met ça:
[23:21:21] [Client thread/INFO] [STDOUT]: [com.maxyfactory.mod.entity.EntityConvoyingBlock:onUpdate:89]: null
puis plusieurs fois ça avant de crasher
[23:21:21] [Server thread/INFO] [STDOUT]: [com.maxyfactory.mod.entity.EntityConvoyingBlock:onUpdate:89]: minecraft:grass[snowy=false]
Ici, c’était un block de terre que j’essayais de déplacer avec le tapis roulant. -
[23:21:21] [Client thread/INFO] [STDOUT]: [com.maxyfactory.mod.entity.EntityConvoyingBlock:onUpdate:89]: null
Oui donc c’est bien ça qui cause le npe. -
Avec if (this.fallTile != null), ça fonctionne mieux : il n’y a plus de crash mais le block est invisible, il n’y a que son ombre.
-
Donc faut chercher pourquoi il est null car il ne devrait pas l’être.
-
Il n’est pas null quand je supprime ça: EntityRegistry.registerModEntity(EntityConvoyingBlock.class, “convoyingBlock”, entityID, ModMaxyFactory.instance, 64, 1, true);
Mais dans ce cas, le doRender() de la class du rendu que j’utilise n’est pas appelé.
Ce n’est pas un problème de mon rendu car c’est une copie de celui du sable donc je ne sais pas d’où ça vient.EDIT : C’est bon, j’ai trouvé pourquoi fallTile était nul : je n’avais pas mis static.
Le rendu fonctionne maintenant mais je voudrais juste savoir a quoi sert static. -
Une variable static n’a qu’une unique instance.
Je ne suis pas sûr que mettre static soit la bonne solution. Envoies ton code complet. -
En effet, static n’ est pas trés bon, si je met deux blocks différents sur des tapis roulants, le premiers devient le même block que le second.

Tu enregistre comment ton rendu ? Car franchement je ne vois pas pourquoi fallTile est null.

Petite remarque surement intéressante:
j’ai mis System.out.println(fallTile+" : "+this); au lieu de System.out.println(fallTile); et sa me met de manière alternée:
[16:12:37] [Server thread/INFO] [STDOUT]: [com.maxyfactory.mod.entity.EntityConvoyingBlock:onUpdate:88]: minecraft:grass[snowy=false] : EntityConvoyingBlock[‘entity.maxyfactory.convoyingBlock.name’/166432, l=‘New World’, x=-635,50, y=5,00, z=-974,50]
et
[16:12:37] [Client thread/INFO] [STDOUT]: [com.maxyfactory.mod.entity.EntityConvoyingBlock:onUpdate:88]: null : EntityConvoyingBlock[‘entity.maxyfactory.convoyingBlock.name’/166432, l=‘MpServer’, x=-635,50, y=5,00, z=-974,50]
quand fallTile est null, l = MpServeur alors que quand fallTile est correcte, l = New Wold (le nom de mon monde)Le Proxy Client :
public class ClientProxy extends CommonProxy{ @Override public void registerRenders() { ItemMod.registerRenders(); BlockMod.registerRenders(); RenderingRegistry.registerEntityRenderingHandler(EntityConvoyingBlock.class, new RenderConvoyingBlock(Minecraft.getMinecraft().getRenderManager())); } } -
Ah surement car c’est null côté client.
Problème de synchro du-coup.
Utilises l’interface IAdditionnalEntityData pour synchroniser le bloc. -
Comment fait-on pour l’utiliser ?
-
Tu ajoutés implements IAdditionalEntityData après la déclaration de ta classe (il me semble que la classe s’appelle comme ça a vérifier) puis tu ajoutés les deux méthodes qu’il te demander d’implémenter. Elles s’utilisent comme celle d’un paquet
-
Eclipse ne trouve pas IAdditionalEntityData, tu est sûr que c’est le bon mon ?
(Désolé d’avoir été si long) -
Non je ne suis pas sûr et je l’ai même précisé dans mon message.
C’est IEntityAdditionalSpawnData
