Hello, I've seen the Forge Wiki and I've read the NBT saving tutorial and is does not work! Here is The Code!

	@Override
public void writeToNBT(NBTTagCompound nbt){
	super.writeToNBT(nbt);
	nbt.setFloat("Power", this.power);
	System.out.println("Writing");
}
@Override
public void readFromNBT(NBTTagCompound nbt){
	super.readFromNBT(nbt);
	this.power = nbt.getFloat("Power");
	System.out.println("Loading");
}

Thanks!

What are the symptoms that make you think that "it does not work"?

It does not save! I enter like 500 power and when the minecraft re-start, it just dissipers! (From: 500 gets 0)!

your problem is that you need to use packets to relay to nbt data from the client to the server (even if its in singleplayer) and when you log out it deletes whatever was saved if you don't

You have no clue about his code or whatever the hell he is doing. Don't just speculate... This might very well be the cause. But you don't know.

INFO: I am making a regular Custom Modelled Block.

"enter like 500 power" - Enter? Where?

Please answer that. We cannot help you otherwise.

I use an Item into a Slot and it Adds 500 of power.(Original Mod Idea(WIP-Can't Identity Item in Slot). Using this.power=500 in debug mode and then deleting it)

I use an Item into a Slot and it Adds 500 of power.

Show the code.

(Original Mod Idea(WIP-Can't Identity Item in Slot)

Wat.

Using this.power=500 in debug mode and then deleting it)

?!

3 Quote: I use a float named "power" that I add 500 by code(this.power=500), using the debug mode I enter my world and I can see the 500 power working, but when I go back to the game MENU and delete the "this.power=500" and re-load the map, It has gone the NBT is not saving the power.

 

2 Quote: Saying my original mod idea. And it's error...

 

Oh! I am using GUIs with it! The Power is a float FROM the Block that is being used on the GUI.

I don't see anything that sets the power field.

Power field?

Debug mode... Just set it in the actual code.

Set it in actual code?

When you use DeBug mode you might bypass some systems that will help MC/FML/Forge recognize your TileEntity has been altered. I never actually thought this would work... Does the TileEntity function in-game as if it has power set at 500?

 

Checklist for TileEntities not behaving:

 

1. Has TileEntity been registered ( GameRegistry.registerTileEntity(..) )

2. Upon modifying internal data (through the game/ not debug-mode) outside vanilla methods... Is the entity marked as dirty? (this.markDirty()) Basically tells MC that your TileEntity has been altered and NBT-data should be updated.

3. If all that fails, MC/FML/Forge isn't able to sync your TileEntity through normal means, you will need to create your own DescriptionPacket.

 

Disclaimer: This list has been compiled from personal experience. It is probably not complete. Use at own risk.

 

Addition: What I am guessing here is that OP uses the Debug-function in their IDE. It will launch MC with the ability to alter the variables through the IDE while the game is running... I guess a breakpoint on the last line in the constructor can allow you to do this kind of stuff OP tries to explain.

Setting variable is debug mode is problematic.

Multiple things to consider:

a) Are you operating on the client thread, or the server thread? (They do not share the same thread!)

b) Can minecraft detect your change? (Usually not, so it will often just set it back to what it knew)

c) Why can you not just make the change in your code and continue running?

d) It usually causes problems anyways.

I've found the problem, my minecraft is saving the TileEntity. But is not loading! My Console Gave me the "Writing..." string but not the "Loading..." string.(readFromNBT(NBTTagCompound nbt))

a) Client Thread

b) I've seen that it saves when I pause the game, but It does not load

c) I change when I'm running, I re-start to see if this really is working

Are you registering your TileEntity class?

Yep, It's Registred in a Client and Common Proxy that I load it on my Main Class:

Why are you only registering it in the ClientProxy?

I think I forgot to register in other one...

Why are you only registering it in the ClientProxy?

I think I forgot to register in other one...

Same... when I re-start the game it has gone!

Same, it didn't worked. I don't know the problem, is there a working way that I could save my files?

Are you still using the debugger to set power? If not, please show code where power gets set.

Are you still using the debugger to set power? If not, please show code where power gets set.

I use the "UpdateEntity" to it, sets it power to "power+=10", when It is full, I remove this command and the power it's still there but when I re-start the game, it is gone, I wanted to make it check If item is in Slot to add power, EX: I inserct Item "Cobblestone" on the slot and It adds 100power.

 

Thank you for your attention,
