[SOLVED]need help using the NBT [1.7.10]

Wand Level

 

...

 

actually and this is final, the cooldown changes depending on what level and type of spell

 

So create a

getCooldown(ItemStack)

method that reads the wand's level and spell from the

ItemStack

and returns the cooldown of the wand in ticks. Replace the

FIRE_RATE

constant with a call to this method in

isOffCooldown

.

Please don't PM me to ask for help. Asking your question in a public thread preserves it for people who are having the same problem in the future.

so while I was waiting for a reply I wrote this code for the cooldown thing and I want to know the errors and flaws about it just so that in the future I can figure this stuff out by myself. also I get this weird bug with checking if the correct owner is the player who is the owner, I started a lan to test it and when the wand transfers from one inventory to another and back to the owners, the owner no longer has access to the spells and info on the wand. why is this ?

aslo for my question earlier:

like this?

	private int getCooldown(ItemStack stack) { 
    int Level = stack.stackTagCompound.getInteger("Level");
    int spell = stack.stackTagCompound.getInteger("Spell");

   if(Level == 1 && spell == 1){
	return 300;
      }
   if(Level == 2 && spell == 1){
	return 270;
     }
   if(Level == 3 && spell == 1){
	return 255;
    }
   if(Level == 3 && spell == 1){
		return 210;
     }
   if(Level == 4 && spell == 2){          
	return 550;                      
   }                                       
   if(Level == 2 && spell == 2){
	return 495;
      }
   if(Level == 3 && spell == 2){
	return 466;
     }
   if(Level == 4 && spell == 2){
	return 385;
    }
   if(Level == 3 && spell == 3){
	return 300;
   }
   if(Level == 4 && spell == 3){
	return 270;
  }
   if(Level == 4 && spell == 4){
		return 650;
   }
   
      return 0;
	} 

private boolean isOffCooldown(ItemStack stack, World world) { 
		return !stack.hasTagCompound() || (world.getTotalWorldTime() - stack.getTagCompound().getLong("LastUseTime")) >= getCooldown(stack); 
	} 

    private void setLastUseTime(ItemStack stack, long time) { 
		stack.setTagInfo("LastUseTime", new NBTTagLong(time)); 
	} 

Im serious don't look at it!!

Don't compare strings with

==

, use the

equals

method. Strings with the same content (which is what the equals method checks) aren't always the same object (which is what the

==

operator checks).

 

Since display names can be changed, I'd recommend storing the

UUID

of the owner instead (which is guaranteed to remain the same); you can get this from the

Entity#getUniqueId

method.

UUID

s are stored in NBT as a

long

for the most significant bits and a

long

for the least significant bits (returned from the appropriate

UUID

getter methods) and can be read back with the

UUID(long,long)

constructor.

 

UsernameCache.getLastKnownUsername

will return the last known username of the player with the specified

UUID

.

 

I'm not too sure what would cause an item to lose its NBT when dropped. Your code is a bit hard to read, I'd recommend using your IDE's auto-format tool and posting it on Gist or Pastebin with syntax highlighting.

 

The cooldown code in the second code block looks right to me.

Please don't PM me to ask for help. Asking your question in a public thread preserves it for people who are having the same problem in the future.

ok here is the code(Formated):

if (itemstack.getTagCompound() == null) {
if (itemstack.hasTagCompound() == false) {

 

This particular check is redundant. If

getTagCompound

returned

null

,

hasTagCompound

will always return

false

; so there's no need to check both.

 

Have you considered moving the spells to their own classes? It would reduce the number of huge if chains in your wand class.

Please don't PM me to ask for help. Asking your question in a public thread preserves it for people who are having the same problem in the future.
