Finding Empty Space In A Chest?

Alright so here is my problem, I'm putting items into a chest, I need to check if there is room in the chest for the item(s) to fit. Now first there is two things we are assuming. 1) Any item being added is the same item. 2) Said item stacks to 64.

Now, this is what I had tried and it didn't work the way I thought it would. I will take any suggestions on how to accomplish this.

(m is the material being put into the chest)

PHP:

int total = 0;
 for(ItemStack i : chest.getInventory().getContents()){
     if(i == null){
       total += 64;
     }
      if(i != null && it.getTypeId() == m.getId()){
        total += i.getAmount();
      }
 }

Thanks!

 

What exactly do you want the plugin to do ?

Tell how many and what are in chests ?

I need to find the amount of free space left in a chest. So 1 slot is = 64 free.

 

Hmm let me check some of my code

Now what you could do is loop through the whole chest and set a variable for each slot that == null then multiply that by 64

That's exactly what I've been trying, this is what I was using in my for loop:

if(i == null){
total += 64;
}

 

Try this type of loop not the exact code though. I toke this from one of my plugins

Code:

private ItemStack[] items;
 
ItemStack[] tempInv = new ItemStack[items.length];
        for (int i=0; i<items.length; i++) {
            ItemStack is = items[i];
            if(is != null)
                tempInv[i] = is.clone();
           
        }

 

I found a way that it was much easier. Feel free to use the code

PHP:

int slots = c.getInventory().getSize();
int totalSpace = 0;
if(slots == 27){
    totalSpace = 1728;
} else if(slots == 54){
    totalSpace = 3456;
}   
       
for(ItemStack it : c.getInventory().getContents()){                                       
    if(it != null ){
        totalSpace -= it.getAmount();
     }
}

 

Thanks but I don't need it.

 

Alright well thanks for the help anyway man!
