Well I am making a custom Fishing rod, and the EntityHook is thrown out perfectly fine, but when I try to retract the fishing rod this is what happens.

It just keeps throwing out a new entity. I could use some help.

 

 

The only class I think that should be needed is the Entity Class.

I had an idea  of maybe trying onItemRightClick if Entity(or bobber? idk) != null set Entity(or bobber?) to dead.

Well fishEntity is not a boolean so I can not set it to true nor false. I did try setting it  equal to null and != null but those did not work. I tried placing it in two different places

Another thing though fishEntity is not the rod its self it's actually an instance of a fishing rod's hook. If this isn't null, the icon image of the fishing rod is slightly different.

 

Another idea please? I really need this working.

Er, not "true". But in the constructor of EntityFishHook there is a line that says "this.angler.fishEntity = this;". Since you're missing that line, angler.fishEntity keeps showing up as null.

 

However, EntityPlayer.fishEntity is type-protected to EntityFishHook. Which you don't extend. So you will need to alter your class to extend EntityFishHook, or else use IExtendedEntityProperties.

BEWARE OF GOD

187. line is;

 

187.				ItemStack itemstack = this.angler.getCurrentEquippedItem();
188.				
189.				if (this.angler.isDead || !this.angler.isEntityAlive() || itemstack == null || !isNewFishingRod(itemstack) || this.getDistanceSqToEntity(this.angler) > 1024.0D) {
190.					this.setDead();
191.					this.angler.fishEntity = null;
192.					return;
193.				}

 

and also maybe you need;

final Item[] newFishingRods = new Item[] { itemref.stoneFishingRod, itemref.ironFishingRod, itemref.goldFishingRod, itemref.diamondFishingRod, itemref.blackDiamondFishingRod, itemref.nightFishingRod };
public boolean isNewFishingRod(ItemStack item) {
	for (int x = 0; x < 6; x++) {
		if (item.getItem() == newFishingRods[x]) {
			return true;
		}
	}
	return false;
}

Pixelmon est un mod populaire pour Minecraft qui permet aux joueurs d'attraper, d'entraîner et de combattre des Pokémon dans le monde de Minecraft. Développé par un groupe de fans dévoués, le mod ajoute une large gamme de créatures Pokémon au jeu. Il possède des fonctionnalités et des mécanismes uniques qui en font une expérience amusante et engageante pour les joueurs de tous âges. Le mod Pixelmon est disponible pour les mondes Minecraft solo et multijoueur et peut être téléchargé et installé à l'aide de divers lanceurs et modpacks. Une fois installé, les joueurs peuvent explorer le monde et rencontrer des Pokémon dans la nature, se battre avec d'autres entraîneurs et créer leur propre équipe de créatures puissantes. L'une des fonctionnalités clés de Pixelmon est la possibilité de capturer et d'entraîner des Pokémon en utilisant diverses méthodes. Les joueurs peuvent fabriquer des Pokéballs et les utiliser pour capturer des Pokémon sauvages, qui peuvent ensuite être entraînés et améliorés au fil du temps.

Dans un univers reprenant les standards du jeu Nintendo original : Dresseurs, centres Pokémon, mais aussi fossiles et matériaux divers. Les Pokémon comme dans le jeu original sont classés par type (Insecte, Ténèbres, Dragon, Électrique, Combat, Feu, Vol, Spectre, Plante, Sol, Glace, Normal, Poison, Psy, Pierre, Acier, Eau), ce qui définira les faiblesses et les spécificités des Pokémons. Par exemple, un Pokémon de type Feu subira deux fois plus de dégâts si l'attaque du Pokémon ennemi est de type Glace. Le mod possède 900 Pokémon différents plus ou moins rares qui apparaîtront en fonction de leur environnement (jour, nuit et biomes). Les Pokémon évoluent en fonction de leur niveau (jusqu'à 100). Plus leur niveau est élevé, plus ils seront forts et auront des attaques plus puissantes. Pour augmenter le niveau de votre Pokémon, et ainsi évoluer, vous devrez combattre d'autres Pokémon et les vaincre. Plus vos adversaires sont forts, plus ils vous rapporteront de l'expérience. Les Pokémons ont également leurs propres statistiques (attaque, défense, vitesse, vitesse d'attaque et vitesse de défense). Ils peuvent également avoir des tailles et des formes différentes, et peuvent occasionnellement vous donner des objets une fois tués. Pour les capturer, vous devrez utiliser des pokéballs, qui selon leur forme seront plus ou moins efficaces. Pixelmon est un mod amusant et engageant pour Minecraft qui ajoute une touche unique et passionnante au jeu. Avec sa large gamme de fonctionnalités et de mécanismes, il offre aux joueurs des possibilités infinies d'exploration et de plaisir, ce qui en fait un choix populaire pour les fans de Minecraft et de Pokemon.  
    • Hi all,  I have the following issue: I'd like to parse some json using gson and rely on the (somewhat new) java record types. This is supported in gson 2.10+. Gson is already a dependency used by minecraft, however it's 2.8.x for 1.19.2 which I'm targeting at the moment. My idea was to include the newer version of the library in my mod and then shadow it so it gets used inside the scope of my mod instead of the older 2.8. This works fine for building the jar: If I decompile my mod.jar, I can see that it's correctly using the shadowed classes. However obviously when using the runClient intellj config, the shadowing doesn't get invoked. Is there any way of invoking shadow when using runClient, or am I on the wrong track and there's a better way of doing this entirely?   Thanks in advance!   Edit: After some further thinking, I've come up with this abomination:   build.gradle // New task for extracting the result of shadowJar into the classes directory // This includes our shadowed gson jar tasks.register("extractShadowJar", Copy) { // Depend on shadowJar so we always use the up to date version of the shadowed content dependsOn shadowJar from(zipTree(shadowJar.archiveFile)) { // filter to copy only our code (and ignore assets, META-INF, etc) // Also copies gson as it gets shadowed into com.oppendev.shadow.gson include "com/**" } duplicatesStrategy(DuplicatesStrategy.INCLUDE) into("$buildDir/classes/java/main") // Extract into the classes directory } // Tell gradle to invoke our new task before executing any java code. This way we ensure that we use the shadowed gson tasks.withType(JavaExec).configureEach { dependsOn(extractShadowJar) } // Shadow config shadowJar { relocate 'com.google.gson', 'com.oppendev.shadow.gson' configurations = [project.configurations.runtimeClasspath] zip64 true dependencies { include(dependency('com.google.code.gson:gson')) } } Is this a reasonable thing to do? Is this completely cursed and I should burn in dev ops hell? Is there a better way to do this? Feel free to grill me in the replies
    • Yep I did upgrade just because it showed me a new version available.  I'll redownload the mod list and make sure anything works.  Thanks!
