[1.7.10] When running on dedicated server I get no such method error

Thornack · May 31, 2015

When I test my mod on a dedicated server and when I trigger the method that transforms the player into his party member I get a no such method error (this doesnt happen in LAN or when in singleplayer)

I have a getMob function, this function gets the entity that the player spawned from his party list by comparing the uuids the player knows with the uuids of entities from the world

//this function gives me a no such method error when I run the server and when player morphs
public static Entity getMob(World world, EntityPlayer player) {
	PlayerParty ppp = PlayerParty.get(player);
	for (Object object : world.getLoadedEntityList()) {
		if (object instanceof EntityPartyMember) {
			EntityPartyMember entity = (EntityPartyMember) object;
			long uuidMost = ppp.getEntityPartyMemberNBTFromSlot(ppp.getSpawnedSlot()).getLong("UUIDMost");
			long uuidLeast =ppp.getEntityPartyMemberNBTFromSlot(ppp.getSpawnedSlot()).getLong("UUIDLeast");
			if (entity.getUniqueID().getMostSignificantBits() == uuidMost && entity.getUniqueID().getLeastSignificantBits() == uuidLeast) {
			return entity;
			}
		}
	}
	System.out.println("DID NOT FIND ENTITY: Entity is Null");
	return null;
}

I have a morph function, this function swaps positions with the entity the player is transforming into and triggers a model/texture switch and will in the future switch their stats and all of that The way it works is as follows

/** The morph method is called from the process method on server side only inside my PacketMorphBtnPressed and the PacketPWReturnBtnPressed classes

* (where these packets are sent to notify server of GUI btn presses and are sent from Client to Server (the process method in these classes is Server side only))

* The method takes a boolean as a parameter and it uses a helper method to get the spawned party member by its UUID, it passes the value

* of the boolean to the setMorphedIntoPlayer method so that the party member entities' model can be updated depending on

* the boolean's value and also uses this boolean to morph or un-morph the player (switch or switch back), it also swaps the positions of the party member with its owner

* player to simulate a player swap.

* @PARAM boolean shouldBeMorphed

*/

For some reason the helper method gives me a no such method exception when I run dedicated server and test. This method is located inside my BattlePlayerProperties class which is a IEEP class that adds additional stuff to the player

public void morph(boolean shouldBeMorphed){
	if(shouldBeMorphed){
	System.out.println("Morphing");
	} else{
	System.out.println("Returning");
	}
	EntityPartyMember morphPartyMember = (EntityPartyMember) WorldHelper.getMob(player.worldObj, player); //this line gives me a no such method error when I run the           server and test Im not sure why This is happening
	morphPartyMember.setMorphedIntoPlayer(shouldBeMorphed);
	double preMorphPosX = this.player.posX;
	double preMorphPosY = this.player.posY;
	double preMorphPosZ = this.player.posZ;
	this.player.setPositionAndUpdate(morphPartyMember.posX, morphPartyMember.posY, morphPartyMember.posZ);
	this.player.prevPosX = morphPartyMember.posX;
	this.player.prevPosY = morphPartyMember.posY;
	this.player.prevPosZ = morphPartyMember.posZ;
	morphPartyMember.setPosition(preMorphPosX, preMorphPosY, preMorphPosZ);
	morphPartyMember.prevPosX = preMorphPosX;
	morphPartyMember.prevPosY = preMorphPosY;
	morphPartyMember.prevPosZ = preMorphPosZ;

}

The consol error log (Please let me know if I have provided enough code/info about this error)
