Création tnt

Sebenf0rce

Bonjour,
J’ai essayé de créer une tnt. J’ai repris le code de la tnt de base de minecraft. J’aimerais cependant modifier sa force d’explosion (afin de casser l’obsidienne) mais je n’y arrive vraiment pas. De plus je ne parviens pas à lui appliquer mes textures (j’ai mis : Main.MODID + “:tnt_side”).
Voici mon code :

 package com.sebenforce;

Merci d’avance.

robin4002

Pour la texture il manque la fonction getIcon.
Pour la force d’explosion il faut faire une entité custom.

Et supprimes cette variable qui ne sert à rien :
private static final String __OBFID = “CL_00000324”;

Sebenf0rce

Ah oui effectivement, j’ai donc ajouté ceci :
@SideOnly(Side.CLIENT)
public IIcon getIcon(int p_149691_1_, int p_149691_2_)
{
return p_149691_1_ == 0 ? this.field_150115_b : (p_149691_1_ == 1 ? this.field_150116_a : this.blockIcon);
}

Par contre le haut et le bas ne s’affiche pas correctement. Comment ça se fait ?

Pour l’entité custom je n’ai pas très bien compris. Que faut-il faire exactement ?

robin4002

Comment ça pas correctement ?

L’entity custom c’est ici :

entitytntprimed.fuse = p_149723_1_.rand.nextInt(entitytntprimed.fuse / 4) + entitytntprimed.fuse / 8;
p_149723_1_.spawnEntityInWorld(entitytntprimed);

Si c’est bien ça, je ne vois pas l’endroit où est géré la puissance de la tnt. Il y a le rayon d’effet mais je ne vois pas ce que je cherche.

Yeyvo

Normale faut crer une classe render pour ton EntityTnt ;D (pence a regardé les Tito de mff)

Deleted

Le f = 4.0f, de la méthode explode () détermine la puissance de l’explosion.

Sebenf0rce

@‘Plaigon’:

Le f = 4.0f, de la méthode explode () détermine la puissance de l’explosion.

J’ai mis la valeur f à 2000 afin de pouvoir détruire l’obsidienne cependant cela fait énormément (voir planter) laguer le jeu. Y a t’il une alternative possible ?
J’ai pris cette valeur car le setResistance est à 2000 pour l’obsidienne, cela a t’il un rapport ?

Sinon pour l’icone j’ai toujours un soucis avec le top et le bottom pourtant j’ai bien ce code :

 public void registerBlockIcons(IIconRegister p_149651_1_)
   {
       this.blockIcon = p_149651_1_.registerIcon(this.getTextureName() + "_side");
       this.field_150116_a = p_149651_1_.registerIcon(this.getTextureName() + "_top");
       this.field_150115_b = p_149651_1_.registerIcon(this.getTextureName() + "_bottom");
   }

De plus je n’ai lorsque la tnt est activé il n’y a plus aucune texture elle disparait, où est l’endroit où cela est définit ?

Merci de votre aide.

robin4002

Pour la texture il faut les logs.
Pour la tnt qui disparaît c’est parce que l’entité n’est pas enregistré.

et pour l’explosion il me semble qu’il faut faire une explosion custom pour augmenter la force sans augmenter le rayon.

Je peux donc créer ma propre explosion mais en utilisant le code déjà existant de la classe Explosion de base j’ai de nombreuse erreurs du fait des fonctions utilisant la classe de base (ex : The method canDropFromExplosion(net.minecraft.world.Explosion) in the type Block is not applicable for the arguments (com.sebenforce.Explosion))

Sinon pour mon problème de rayon j’ai repéré ceci :
float f1 = this.explosionSize * (0.7F + this.worldObj.rand.nextFloat() * 0.6F);

Cependant la taille n’est pas modifier par la force que je modifie moi même non ?

AymericRed

Pour résoudre tes erreurs, extends tout simplement ta classe Explosion.

Sebenf0rce

Niquel ça marche merci. Maintenant je ne vois pas très bien comment résoudre mon problème initial. Empêcher les lags suite à l’explosion de la tnt car je n’ai modifié qu’un paramètre (la force) qui n’a pas d’impact sur les autre valeurs.

AymericRed

Empėcher les lags ? Même les explosions Vanilla laguent mais tu peux essayer de faire spawn moins de particules ou encore ne pas faire spawn les EntityItem des blocks…

Le problème c’est que là j’ai augmenté la puissance à 2000F pour pouvoir casser la tnt mais du coup ça fait limite crashé le jeu. Je ne trouve pas où réduire le rayon de la tnt.

Sinon pour register l’entité ce n’est pas comme ça ? :
EntityRegistry.registerModEntity(TntZenodium.class, “tntZenodium”, 30, Main.MODID, 1, 1, true);

Salut Sebenf0rce,
Pour palier à ton problème, tu peux peut-être essayer de redéfinir la méthode doExplosionA() ?
C’est la méthode qui permet de détruire les blocks adjacent à ta TNT. Dans cette méthode tu as un test à un moment :

  
Block block = this.worldObj.getBlock(j1, k1, l1);
if (block.getMaterial() != Material.air) {
float f3 = this.exploder != null ? this.exploder.func_145772_a(this, this.worldObj, j1, k1, l1, block) : block.getExplosionResistance(this.exploder, worldObj, j1, k1, l1, explosionX, explosionY, explosionZ);
f1 -= (f3 + 0.3F) * f2;
}

Si je ne dis pas de bétises, il me semble que tu récupères la résistance des blocks adjacent à ta TNT.
Modifie le pour que si le block détecté est un block d’obsidienne alors la résistance f3 retranchée à f1 soit petite (genre tu mets un f3 = à la resistance de la dirt par exemple).
Et tu gardes une valeur d’explosion relativement faible ce qui va réduire tes lags et ton rayon d’action.
PS : Je suis pas chez moi pour l’instant, je ne peux pas tester ce que j’avance mais je le fais dès que j’arrive
Bon courage et en espérant avoir aidé !

Sebenf0rce

Salut,
J’ai essayé de faire ce que tu m’as dit mais le jeu crash, voila mon nouveau code :

 if (block.getMaterial() != Material.air)
                           {
                            if(block.getMaterial() == Blocks.obsidian.getMaterial()) {
                             float f3 =  2.0f;
                             f1 -= (f3 + 0.3F) * f2;
                            }
                            else {
                               float f3 = this.exploder != null ? this.exploder.func_145772_a(this, this.worldObj, j1, k1, l1, block) : block.getExplosionResistance(this.exploder, worldObj, j1, k1, l1, explosionX, explosionY, explosionZ);
                               f1 -= (f3 + 0.3F) * f2;
                           }
                           }

Suis-je partis sur une mauvaise base ?

Myrilandel

Attention, si tu regardes le block d’obsidienne, il étend la classe BlockStone qui a pour material stone, du coup ta TNT risque de ravager à la fois l’obsidienne mais aussi tout les blocks de stone, cobble etc…
J’ai essayé en modifiant la méthode comme ça et ça a marché :

  
if (block.getMaterial() != Material.air)
{
      float f3 = this.exploder != null ?
            this.exploder.func_145772_a(this, this.worldObj, j1, k1, l1, block) :
            block.getExplosionResistance(this.exploder, worldObj, j1, k1, l1, explosionX, explosionY, explosionZ);
 
     if(block == Blocks.obsidian)
             f3 = 1.0F;
 
      f1 -= (f3 + 0.3F) * f2;
}

Si ça plante encore, envoie le rapport d’erreur s’il te plait : )

robin4002

C’est en effet ici que la résistance du bloc est prit en compte :

 for (float f2 = 0.3F; f1 > 0.0F; f1 -= f2 * 0.75F)
{
int j1 = MathHelper.floor_double(d5);
int k1 = MathHelper.floor_double(d6);
int l1 = MathHelper.floor_double(d7);
Block block = this.worldObj.getBlock(j1, k1, l1);
 
if (block.getMaterial() != Material.air)
{
float f3 = this.exploder != null ? this.exploder.func_145772_a(this, this.worldObj, j1, k1, l1, block) : block.getExplosionResistance(this.exploder, worldObj, j1, k1, l1, explosionX, explosionY, explosionZ);
f1 -= (f3 + 0.3F) * f2;
}
 
if (f1 > 0.0F && (this.exploder == null || this.exploder.func_145774_a(this, this.worldObj, j1, k1, l1, block, f1)))
{
hashset.add(new ChunkPosition(j1, k1, l1));
}
 
d5 += d0 * (double)f2;
d6 += d1 * (double)f2;
d7 += d2 * (double)f2;
}

Dans la deuxième condition il suffit d’enlever f1 > 0.0F et ça devrait être bon.
