I'm making a mod with a spear in it and when you throw it you can go over and pick it back up. How would I make so that you pick up the exact same spear you threw with enchantments, and damage, and everything. I thought about using "this", but the spear pick up code is in the entity class so I can't do that. Is there any way to instead of "this" do "that"? Any way, what realistic way could I solve my problem, would packaging all the data I want the spear to keep into nbt data and sending it to the entity work?

Yes, you could just put an ItemStack (the spear item with enchants and other things on it) into the entity. ItemStack can serialize itself into NBT ;).

Hmm, well I've always had trouble with the difference between itemStack and item, so I don't necessarily know how to do that...

 

Minecraft code is a little funky.

 

Item classes are a singleton* instance (as is all Block classes).  An ItemStack is a class that allows the entire inventory system to function.  Every item in your inventory is a stack of items (even if the stack size is 1).  Essentially, it's a wrapper class that allows for instancing of the singleton class.  ItemStacks have enchantments, Items don't.

 

*It's actually not, but it's easier to think of it as if it is because it's only ever instanced once.

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

Ahh, thanks. Damage is also on the itemstack too right? Like when you use an inventory an you stack weapons they all have the same damage value. Also how would you set the spear as an itemstack and send it to the entity's pickup code?

Correct, damage is on the stack.

As for the pickup code, rather than telling the entity that it drops the base item class, tell it to drop a new ItemStack that has all the properties of what the original was, which you'd store as NBT data inside the entity.

 

(Not having dealt with projectiles, I can't really comment more).

So how would I have my code call the Item an itemstack?

 

When I do this...

public static ItemStack thisSpear = new ItemStack(this, 1);

It says this can't be used with a static modifier but adding the static modifier is the only way to get the entity to read it.

 

I'll look at the entityItem code, that might have some insight on my dilemma.

Do you understand what the keyword static means?

you're title indicates some confusion to the this word which is closely related to the understanding of static. I would suggest that you take some time to read up on the topic of instances and static inn programming, you will benefit greatly from it! :)

 

I'm not saying it to be mean mate, it's just that what you said above here shows that you seem confused about the concepts and since it's vital for you to know them, I urge you to look them up when you have the time it will help you out greatly with developing your mod(s) :)

Thanks Maze, that was a good tip.

 

I read the article oracle posted on instances and that does clear a lot up for me. I couldn't use "this" in another class because it wouldn't know what instance "this" was referring to.

 

So I tried putting this in the on release function...

 

EntitySpear.spearToDrop =  par3EntityPlayer.inventory.getCurrentItem();

 

And it works... kind of. It gives me back the exact spear I threw, damage, custom name, enchantment everything, but when I throw it again it just bounces off the entity I threw it at and does no damage. And when I try to attack with it it immediately deletes itself from my inventory.

I'm just guessing, but for me that sounds like a client/server sync issue.

You're client think's it has picked up the item, but the server is never told that it did.

Therefore the server is not aware of the item and when it's used the client says it hit and landed while the server is like "Spear? what spear? oh that thing, you never picked it up from where you left it the last time..?"

 

So you are on the right track I'd guess, but you need to start communicating with the server about what the client is doing :) Are you familiar with packets and packet handling?

Yeey I made someone learn more Java  ;D

// Start pushing more java

If you want some quick intros to java check out thenewboston on google, or if you are inn for a more lengthy but very rewarding run check out CS106a - a free video lecture series on java from Stanford, which starts at the very basics and go as far as you want ;)

// End of java pushing.

 

Seriously if you want to learn more, it's great! It will make your mods better and not to mention it will make the creation of them so much easier when you know what you are doing <3

Ok, I get the concept, but that's it  :D

 

Using the tutorial you linked to I was able to set up the random numbers being displayed when the player collides with the spear entity, and I noticed as I was messing around that if you put the addItemstack line in the spear entity's onCollide method try section it did the same thing as if it were just in the onCollide method.

 

Do you put the addItemstack line in the packet handler file? When I tried putting that next to the system.out.print line it through a fit because it didn't like the EntityPlayer variable.

    • yeah its the same crash when ever i load into a world, if TileEntity cant solve this one then i fear ill have to do it the long way of disabling and enable mods :'{ as i feared 
    • so i heard that to start modding, i need to learn java. doing that. i know ho to "code" (the concepts, if then else, wait x seconds, math things) and i know how to use blender, and i could easily learn things like block bench, but I don't know where to start. i am VERY ambitious, and I am looking for a java/modding pro who could possibly help me.  please help.
    • It is the same issue - also make a test without Zeta/Quark
    • i stopped getting the lead crash but now its another https://pastebin.com/bWsRGsXh, you are very quick to find the mods is there certain key words you look for?
