So, i am working in a Spear, and it can work like a sword, or like a snowball. And i have a problem beetween these 2 friends.

 

I think you allready know, but, when i right click with the Spear, it generates its Entity, because an Item cant get flying arround out there. But, as it is also a "sword" it has that tool stuff, about its usage.

 

Know comes the issue, if i throw the Spear, i can pick it up, but when i do, it doesnt has the same usage as before i threw it. For example, i saw a zombie, i hitted it, and killed it, and then i saw a creeper, and i trhew the Spear at it, and jnow it is dead \o/... So, i go back to my spear, and when i pick it, its new, like i have never hitted a zombie. Ahhhhhhhhhhh, got it?

 

So, i keep thinking that, if i write to the NBT it will solve, but i dont know if it is the Entity NBT, the Item NBT, both, and i dont know also to how to comunicatw these two.

 

Hope you get it.

 

See ya

 

Do you pick it up as an EntityItem or does it work like an arrow?

The arrow i more a bullet, it is shooted, but mine is it, i dont need any weapon. I dont know the meaning of EntityItem there, but, i saw the ItemArrow (fucking on update,  did you see its size?) and i copied it. Before i doing that i used the snowbalk code, but we cant pick it back, so i used the arrow anyway...

In which case you need to transfer Item NBT to Entity NBT and back to Item NBT. Actually, you could probably do it without NBT, easily enough.

How?

When you create the entity, set a damage value variable. Then, when you pick it up, transfer that variable's value back into the ItemStack metadata.

Thanks you so much, i will try it now...

Hey, i must tell you something bro, i dont know java very well 

 

But i keep trying and trying, until know i did some stuff, just read::

 

ItemDamage = the damage the items has, it is an public static int

 

 

I added too an method at the  EntitySpear that is a public int

 

 public int takeSpearDamage(int x)
Return this.Spear.ItemDamage = this.Speat.ItemDamage - x;

 

Just on the method you can see that i cant make a diference beetween the old and new int

 

 

See ya

Bump

 

Look,

 

 

SET UP

 

in the Item, we have ItemDamage, that is an int, and is about getting the item life "taken"

 

in the Enttiy we just have this.setDead, so, we dont have half life, or is it dead, or is it life

 

I want to put the ItemDamage to the Entity, so i do

public int ItemDamage

 

At the Entity i do

public ItemSpear Spear

 

Now, i can do Spear.Item

 

 

PART A

 

How to use it?

 

How to every time that the Enttiy Intialize it can get that damage.

 

For initializing we know that we use the entityInit()

 

PART B

 

As a guess, i created a public int, it is

public int getItemDamage(something about x, dont remember)
{ 
return Spear.ItemDamage 
]

 

I think that my guess is a piece of shit, cause we need to teel that this cucker is that sucker so i THINK we must put

(WorldObj remute stuff), but i dont know how to use it, if statement? i dont have anyother condition... I am pretty new to JAVA.

 

PART 3

 

When it hits the target entity, it get "hurts" ( i think that is putting the animal int (public int getMaxHealth this can get hurt, but i think i might not work, cause i belive it can get hurt(red stuff))) but how do i do that? With my noobity of JAVA i kept creating methods with no certain.

public int takeItemDamage(another x stuff)
{
return Spear.ItemDamage - x = Spear.ItemDamage
}

 

For me, the codes makes senses, because thats the algebra i must do, except that cant show that it is a last ItemDamage, we have the last and the new item damage, and also that wordremote stuff

 

END

 

If you red all of this i give you really thanks, really, and if you do help it will be really greatfull

 

 

See ya

 

Sry, bump

Sry, bump

QUADRA POST! (Sorry, I was busy and couldn't help people.)

Ugh, your English as well as your knowledge of Java pains me, but I'll try to help anyway.

 

First of all, you don't want an ItemSpear attribute in your Entity, you want an ItemStack. When you initialize your entity (find the place in your ItemSpear where you call a new instance of EntitySpear), set theEntitySpear.Spear = this;

Now look in your EntitySpear. I assume you copied onUpdate from EntityArrow? There's extra stuff in there you'll want to trim out, but for now, we can say: find the place where it says

if(!(movingobjectposition.entityHit instanceof EntityEnderman)){
    this.setDead();
}

and add these lines (in bold):

if(!(movingobjectposition.entityHit instanceof EntityEnderman)){
    this.setDead();
    [b]this.Stack.setItemDamage(this.Stack.getItemDamage()-whatever);
    this.entityDropItem(this.Stack,yOffset);[/b]
}

Replace "whatever" and "yOffset" with whatever you feel like.

Yeah sorry about the english and Java hehe

 

Thanks, i will try

 

I know that EntityEnderman stuff.

 

 

 

See ya

Yeah, instead of EntityEnderman, puts EntityLiving

Um, no. The EntityEnderman thing is because arrows have no effect on endermen. If your spear has effect on endermen, put those two lines outside of the if block.

No, i mean the decresing of the arrow "life" by hitting and EntityLiving

No, i mean the decresing of the arrow "life" by hitting and EntityLiving

Well, in that case, you'll want to get rid of the bang.

Didnt worked

What do you mean by that? How does it fail?

The entity crashes, the problem is at the line about the ItemStack stuff...

The entity crashes, the problem is at the line about the ItemStack stuff...

What's the crash log?

I will get it in one sec

Sorry for the "sec'"  :B

-snip-

Sorry for the "sec'"  :B

I have all the time in the world.  In the future, though, please put the logs in spoilers.

 

What, exactly, is line 370?

There was something about ItemStack, but not with yoffset param..

 

The third line

 

if(!(movingobjectposition.entityHit instanceof EntityEnderman)){

    this.setDead();

    this.Stack.setItemDamage(this.Stack.getItemDamage()-whatever);

    this.entityDropItem(this.Stack,yOffset);

}

 

 

I will think a little bit more,

 

See ya

So, i will follow the main idea of the creator of the mod, and will use these codes

 

Item

 

 

    public boolean onBlockDestroyed(ItemStack par1ItemStack, World par2World, int par3, int par4, int par5, int par6, EntityLiving par7EntityLiving)
    {
    	par1ItemStack.damageItem(0, par7EntityLiving);
    	
    	if(this.itemRand.nextInt(3) == 0)
    	{
    		par1ItemStack.damageItem(10000000, par7EntityLiving);
    	}

        return true;
    }

    public boolean hitEntity(ItemStack par1ItemStack, EntityLiving par2EntityLiving, EntityLiving par3EntityLiving)
    {
    	par1ItemStack.damageItem(0, par2EntityLiving);
    	
    	if(this.itemRand.nextInt(6) == 0)
  		 {
    		par1ItemStack.damageItem(10000000, par2EntityLiving);
  		 }

        return true;
    }

 

 

 

Entity

 

 

if (movingobjectposition.entityHit instanceof EntityCreature)
                        {
                        	if(this.rand.nextInt(6) == 0)
                     		 {
                                this.setDead();
                     		 }

                        }
[/spoiler]
