show the class where you need it,
and normally you use CompoundNBT to save data

[zaze]

my item class that i what to get the power https://github.com/zaze06/sifi-mek/blob/master/src/main/java/me/alien/meksifi/mek/items/Test.java

my class that implements IEnergyStorage https://github.com/zaze06/sifi-mek/blob/master/src/main/java/me/alien/meksifi/mek/Energy.java

and my provider if its needed https://github.com/zaze06/sifi-mek/blob/master/src/main/java/me/alien/meksifi/mek/Provider.java

NBT is for saving data to disk, not for runtime storage.

if I understand your item code correctly you want to add the energy to the item as information
if this is correct you can get your energy with ItemStack#getCapability

[zaze]

yes that probobly what i need i just can't find where i whuld get the capabolity from but it may just me me

 

[zaze]

i have acces to the provider im my item class so can i get it from the provider?

[Draco18s]

ItemStack#getCapability

[zaze]

yes but i need a capability<? extends Object> and i cant finnd where i can get it

[zaze]

and it tells me that it runs the method from my provider that i have as a variabel but is it anather one that contains difrent information in the ItemStack#getCapability

do something like that:
replaced <capability> with the following:
and you should have something like this for your capability somewhere:
 

	@CapabilityInject(IEnergyStorage.class)
	public static Capability<IEnergyStorage> ENERGY = null;

 

stack.getCapability(<capability>, null).orElseThrow(NullPointerException::new);

Edit: I just saw that you are using CapabilityEnergy#ENERGY for your capability (should work too)
