read and write NBT help <SOLVED>

Recommended Posts

Hi, I learned how to create a custom furnace following steps of a tutorial I saw recently developed a code that near the end, I'm just having some problems with respect to reading and writing of NBTTags (which is responsible in this case to allow the information of TileEntitys persist before the savegames), more specifically, my code so it works in a way, my question really is with respect to the criteria that the game system uses to make the call of the writeToNBT TileEntitys, in my case it only calls when I click on esc and then open the menu screen, the otherwise happens passively with auto saved.

Only in the first case (when i click esc) the call only happens when some block changes its inventory (or retreat when I put any item in any slot), otherwise the call does not happen (to test so I put a System.out.println ("write ") in writeToNBT and looked in the console :) ) if the change happens without my intervene (as an item to be cooked and stored in slot 3) when I click the esc the call to writeToNBT not happen (as if the system does not could sees the change), then I thought it would be boring as eg for a player if he put

8 iron ingot and at a given time that 4 has been completed and then without even interact with the furnace he decides to leave the game. then when he returns he looks the furnace and observes the 8 iron ingot intact.

It may seem little since it can count on the passive update (and thus ensure that a huge amount stay without being updated), but I'm a little detail and wanted to fix that little problem.

 

What I really want to know if it is possible to force the system to call the call writeToNBT at a desired time (more precisely when the player click esc and open the menu) and thus ensure that the NBT be updated at the right time.

 

if you want to look at learning the code follows the link from my repository in git hub (will not do that here not to make the topic get bigger than it already was :), besides the more you forgive me if I could not express myself more briefly, I am foreign and do not speak english well).

Thank you for your attention and for the help.

hi diesieben07, is just that, besides the more thanks to your tip managed to find a flaw in my code a look:

 

@Override
public void updateEntity() {
	boolean flag1 = burnTime > 0;
	boolean flag2 = false;
	if (isBurning()) {
		burnTime--;
	}
	if (!worldObj.isRemote) {
		if (burnTime == 0 && canSmelt()) {
			currentItemBurnTime = burnTime = getItemBurnTime(slots[1]);
			if (isBurning()) {
				flag2 = true;

				if (slots[1] != null) {
					slots[1].stackSize--;

					if (slots[1].stackSize == 0) {
						slots[1] = slots[1].getItem().getContainerItem(
								slots[1]);
					}
				}
			}
		}
		if (isBurning() && canSmelt()) {
			cookTime++;

			if (cookTime == furnaceSpeed) {
				cookTime = 0;
				smeltItem();
                                      
                                         // Exactly here !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
				flag2 = true;
                                        // !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

			}
		} else {
			cookTime = 0;
		}

		if (flag1 != isBurning()) {
			flag2 = true;
			InductionFurnaceBlock.updateFurnaceBlockState(burnTime > 0,
					worldObj, xCoord, yCoord, zCoord);
		}
	}
	if (flag2) {
		markDirty();
	}
}

 

at the point where I scored in the code before I was using the first flag, so it was not detected when a particular item was cooked in the furnace, only when I changed something myself.

 

very grateful for the help friend.

If you're looking at a GUI, you may need to call:

if (worldObj != null) worldObj.markBlockForUpdate(xCoord, yCoord, zCoord);

So that the server detects and sends changes to the client.

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

 

Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

 

DO NOT PM ME WITH PROBLEMS. No help will be given.

    • Well don't I feel dumb, thank you as always @TileEntity you're the GOAT
    • Here is my code: @Mod.EventBusSubscriber(modid = Mod.MODID, bus = Mod.EventBusSubscriber.Bus.FORGE, value = Dist.CLIENT) public class PlayerRenderModifications { @SubscribeEvent public static void prePlayerRender(RenderPlayerEvent.Pre evt) { RenderSystem.setShaderColor(0.0F, 1.0F, 1.0F, 1.0F); } @SubscribeEvent public static void postPlayerRender(RenderPlayerEvent.Post evt) { RenderSystem.setShaderColor(1.0F, 1.0F, 1.0F, 1.0F); } } This code is supposed to tint the player blue, however it doesn't tint the player at all (yes i know it only runs in f5 mode or when rendering players in multiplayer). I had also done some testing and it seems if I remove "postPlayerRender" then it tints the player, and also tints everything else that renders after the player (like other entities, clouds, etc.)   If you need me to provide other information then go ahead and ask!
