Increase stack sizes

Hello I am new to coding and I want to code a plugin so I can get used to all the events I have to use, I came across this plugin and I was wondering if anyone could give me a jump start, please don't spoonfeed me that's the last thing I want to do, just someone give me a heads up on how I can get closer to my goal for this plugin. What I was wanting to do is change the stackamount for a certain item.

Thanks for all the help!

 

isn't there a setAmount method in item stack?

 

Yeah, but if you pick up and place down ab overflowed stack, ut splits up.

 

@mcdorli Yeah I saw that except I cannot find anything on the web on how to put that into a method

 

How do you mean you don't know how to put it in a method?

 

For instance I could make a class extend the javaplugin and all, make the public void and I dunno how I would make it so when the bucket enters the players inventory it scans for others of the same material and then stacks them. I don't know how to put that into code.

@mcdorli

 

You need a playerpickupitemevent

 

@mcdorli I will try and test for a bit

 

I think you could achieve this nicely by modifying one of the packets (idk which xD).

 

@DoggyCode™ Don't have a clue what packets are xD

 

Packets are basically the only access we have to modify the game.

You can find a list of them here: http://wiki.vg/Protocol (they allow you to do client side cool stuff)

 

Ahh okay I understand @DoggyCode™

I got somewhere with another plugin I was testing but for some reason when I change the b.getType to b.getDrops it starts throwing the red lines at me. Any idea on how to fix this? Here is my code http://pastebin.com/y2CxM3W5

 

getDrops should return a ItemStack list. Loop through it

Code:

for(ItemStack item : b.getDrops()){
  //then add the item to the inventory
  p.getInventory().addItem(item);
}

Edit:
Or idk, possibly do something like:

Code:

//make an ItemStack array
ItemStack[] itemStacks = b.getDrops();
//I believe you can add arrays to inventory 
p.getInventory().addItem(itemStacks);

 

Thanks man, from all the java researching I did last never I never saw for? I did do java a long time ago and it does ring a bell is it something to do with numbers like doubles or floats?

 

Umm, yeah, number increment are often done in loops. I'd suggest you take a look at all the possible loops: http://www.tutorialspoint.com/java/java_loop_control.htm

Generally, you have the for loop and while loop, but there are some others. Example:

Code:

int i = 0;
//this loop would stop whenever i reached 10
while(i<10){
  i++; //increases the int by one every time it loops
}

You would probably use the for loop more

 

Okay so I got all that working thanks, I wanted to go on from this plugin and to make a autosmelt method, in my case will I have to create a list of blocks that will be autosmelted if entered into the players inventory? I can explain what I want but I don't know how to do it xD For instance I can make lists but I don't have a clue on what the code is for autosmelting. Could u start me off? xD @DoggyCode™

 

I could probably, but I need to go. However, there should be some sort of inventory event that detects whenever you get a item in ur inventory.

 

@DoggyCode™ Okay no worries I will take a look at the java api docs
