Hey guys,

 

I am trying to make a Custom EntityItem, which, when spawned, does not rotate nor have gravity.

 

The EntityCustomItem looks like this:

public class EntityCustomItem extends EntityItem
{

public EntityCustomItem(World par1World, double par2, double par4,
		double par6, ItemStack par8ItemStack) {
	super(par1World, par2, par4, par6, par8ItemStack);

}

    protected void entityInit()
    {
        this.getDataWatcher().addObjectByDataType(10, 5);
    }

public void onUpdate()
{

}

    public void onCollideWithPlayer(EntityPlayer par1EntityPlayer)
    {
    	
    }
}

 

The problem is, that the serverside spawned Item behaves like the normal one and the clientside only flickers.

This happens, when the Entity is not registered to Forge

 

When it's registered, i get this error, when the Entity is spawned:

Alright, let me give you some pointers in the right direction.

 

First, Errorlogs generally are there not to be annoying and bothersome, although I don't deny they are, but to point you to the correct error and where it happens. So read the Log! And this is the second time in an hour or so I say this.

 

Your log says it all:

 



Caused by: java.lang.NoSuchMethodException: com.fertilisNatura.fertilisNatura.EntityCustomItem.<init>(net.minecraft.world.World)

	at java.lang.Class.getConstructor0(Unknown Source) ~[?:1.7.0_25]

	at java.lang.Class.getConstructor(Unknown Source) ~[?:1.7.0_25]

	at cpw.mods.fml.common.network.internal.EntitySpawnHandler.spawnEntity(EntitySpawnHandler.java:72) ~[EntitySpawnHandler.class:?]

[/Code]

 

It can't get the correct constructor. Ie. You're passing or doing something that a normal EntityItem doesn't ask.

 

Secondly I wouldn't inherit from EntityItem if I were you.

This is simply my opinion but I'd inherit from Entity like EntityItem does and simply copy the code and adjust were necessary. It generally allows you to be a bit more flexible but obviously causes a bit of code redunancy. E.g it's a preference.

 

If you do inherit from EntityItem. Then add @Override to your methods, I can't see how you would even interact with your base class if you simply add dead methods that aren't called anywhere.

 

Thirdly, putting your subject title in capitals generally doesn't really help with anything.
