[UNSOLVED]Strange things happen with my energysystem[1.8]

[ItsAMysteriousYT]

Im working on an energysystem in my mod atm and a really weird bug accurd - when i connect the blocks with each other (using a variable in IEEP), then at some point the tileentity they are connected to is the same for all of them and sometimes even a tileentity that is not in the circuit. I don't know if the bug is positioned in the saving of the coordinates or somewhere else. Hopefully someone can help me fix this. Here are the classes i use:

TileEntity_Electric:

 

 

package itsamysterious.mods.reallifemod.core.blocks.tiles;

 

import itsamysterious.mods.reallifemod.core.tiles.RLMTileEntity;

public class TileEntity_Electric extends RLMTileEntity implements IUpdatePlayerListBox{

public TileEntity_Electric from;

private float voltage;

private int age;

private boolean isConnected;

 

public TileEntity_Electric(String string) {

super(string);

 

}

 

public TileEntity_Electric(String string, int i) {

this(string);

this.rotation=i;

}

 

@Override

public void update() {

    if(from!=null){

    voltage = from.getVoltageValue();

    isConnected=true;

    }else{

    isConnected=false;

    }

   

}

 

 

    @Override

    public void writeToNBT(NBTTagCompound compound){

    NBTTagCompound tag=new NBTTagCompound();

    compound.setTag("RLMElectrizityTag", tag);

    if(from!=null){

    BlockPos pto = from.getPos();

    tag.setIntArray("ConectedTo", new int[]{pto.getX(),pto.getY(),pto.getZ()});

    }

    super.writeToNBT(compound);

 

    }

   

    @Override

    public void readFromNBT(NBTTagCompound compound) {

    super.readFromNBT(compound);

    NBTTagCompound rlmtag = compound.getCompoundTag("RLMTileTag");

    NBTTagCompound tag=rlmtag.getCompoundTag("RLMElectrizityTag");

    int[] i = tag.getIntArray("ConectedTo");

    if(i.length==3){

    //if(worldObj.isRemote&&worldObj.getTileEntity(new BlockPos(i[0],i[1],i[2])) instanceof TileEntity_Electric){

        //this.connectTo((TileEntity_Electric)worldObj.getTileEntity(new BlockPos(i[0],i[1],i[2])));

    // }

    }

worldObj.markBlockForUpdate(getPos());

    this.rotation=tag.getFloat("Rotation");

    }

 

public void connectTo(TileEntity_Electric t){

this.from = t;

}

 

public float getVoltageValue() {

float value=voltage;

this.voltage=0;

return value;

}

 

public float getVoltage() {

return voltage;

}

 

public void setVoltage(float voltage) {

this.voltage = voltage;

}

 

}

[Failender]

public class ItemCable extends Item{
private static TileEntity_Electric lastTile;

 

i told you this already in two other posts. DONT USE STATIC if you have NO idea what it is doing. Dont save variables in the item classs u need to use NBT if u want them to save data

[ItsAMysteriousYT]

That variable is nt used anymore, just a leftover. I know what static does, im now using IEEP to save the last TileEntityElectric in it -like diesieben07 said.

[ItsAMysteriousYT]

anyone? I think that the bug is somewhere in the saving part but i can't find it.

[ItsAMysteriousYT]

How can the tileentityelectricfield can be shown as a non-tileentityelectric tileentity??? PLEASE HELP or at least say me where the problem could be

[ItsAMysteriousYT]

Does nobody has an idea? Please - at least tell me if you haven't im really getting mad on this weird bug. I bet its one of the most obvious things and im just to stupid too see it :'(

[Failender]

stop bumping every 2 hours. if some1 is reading he will answer.

[ItsAMysteriousYT]

Im Sorry... was a bit angry yesterday Ill just wait for an answer and try getting it right myself

[diesieben07]

TileEntities must have a public constructor without any arguments. I highly recommend you only have this one constructor in your TE, everything else will get confusing.

[ItsAMysteriousYT]

Yes, i updated all my tiles so that the rotation is being set in OnBlockPlaced by and is initially set too zero. No i only have one constructor that looks like this:

 

public TileEntityElectric(){

  super("TileEntityElectric");

}

 

OH - maybe i can solve the problem if i register TileEntityElectric? Cuz its just a class that is never use as itself - only as extended class?

[ItsAMysteriousYT]

Nah didn't solved it. I reworked some of the methods and classes but now some of the tileentities immediatly disappear after placing. I think it is caused by wrong saving to NBT. Here is the baseclass and the not working subclssses:

[ItsAMysteriousYT]

OMG - MY stupidness solved the disappearing - i forgot to do super.writeToNBT() in TileENtity_Electric witch caused that all entities without NBT were okay and those with NBT where removed. But now the saving of the connected tile won't work. I try writing the BlockPos of the tile to NBT like this:

 

 

 

    @Override

    public void writeToNBT(NBTTagCompound compound){

    super.writeToNBT(compound);

    NBTTagCompound tag=new NBTTagCompound();

    if(to!=null){

    BlockPos pto = to.getPos();

    NBTTagCompound blockPosNBT = new NBTTagCompound();       

    blockPosNBT.setInteger("x", pto.getX());

    blockPosNBT.setInteger("y", pto.getY());

    blockPosNBT.setInteger("z", pto.getZ());

    compound.setTag("connectedBlock", blockPosNBT);   

    }

    compound.setTag("RLMElectrizityTag", tag);

    }

   

    @Override

    public void readFromNBT(NBTTagCompound compound) {

    super.readFromNBT(compound);

 

    final int NBT_INT_ID = 3;

 

    NBTTagCompound tag=compound.getCompoundTag("RLMElectrizityTag");

   

    NBTTagCompound blockPosNBT = compound.getCompoundTag("connectedBlock");

BlockPos readBlockPos = null;

if (blockPosNBT.hasKey("x", NBT_INT_ID) && blockPosNBT.hasKey("y", NBT_INT_ID) && blockPosNBT.hasKey("z", NBT_INT_ID) ) {

readBlockPos = new BlockPos(blockPosNBT.getInteger("x"), blockPosNBT.getInteger("y"), blockPosNBT.getInteger("z"));

}

if(worldObj!=null&&readBlockPos!=null&&worldObj.getTileEntity(readBlockPos) instanceof TileEntity_Electric){

to = (TileEntity_Electric) worldObj.getTileEntity(readBlockPos);

}

    }

 

 

 

But when i close the world and open it again, the 'to' variable isn't set.

 

[diesieben07]

There is no world yet in

readFromNBT

.

[Failender]

only read the position and access the tileentity when you need it

[ItsAMysteriousYT]

There is no world yet in

readFromNBT

.

 

So what im doing there atm will work in the future ? Cuz you say there is no fututre Yet. Also - the onBlockPlacedBy method i tried isn't working. Do i have to put it in the subclasses to?

 

public abstract class RLMBlockContainer extends Block implements ITileEntityProvider{

public RLMBlockContainer(Material materialIn) {
	super(materialIn);
}

@Override
public abstract TileEntity createNewTileEntity(World worldIn, int meta);

    public void onBlockPlacedBy(World worldIn, BlockPos pos, IBlockState state, EntityLivingBase placer, ItemStack stack) {
    	super.onBlockPlacedBy(worldIn, pos, state, placer, stack);
    	 TileEntity tileentity = worldIn.getTileEntity(pos);
         if (tileentity instanceof RLMTileEntity){
        	 RLMTileEntity tile = (RLMTileEntity)tileentity;
        	 tile.rotation = 90 * MathHelper.floor_double((double)(placer.rotationYaw * 4.0F / 360.0F) + 0.5D) & 3;
        	 worldIn.markBlockForUpdate(pos);
             System.out.println("Succesfully rotated "+tile.getName());
         }
    }
    
    @SideOnly(Side.CLIENT)
    public EnumWorldBlockLayer getBlockLayer()
    {
      return EnumWorldBlockLayer.SOLID;
    }
    
    @Override
    public boolean isFullCube() {
    	return true;
    }

[ItsAMysteriousYT]

only read the position and access the tileentity when you need it

 

But i need to load it up immediatly, so the electrizity is being cast when player joines in world. So can i just set a global variable and in the update method put something like that:

 

if(to==null&&toCoords!=null){
  this.to=(TileEntity_Electric)worldObj.getTileEntity(toCoords);
}

[diesieben07]

I have no idea what you are trying to say with the "no future yet" stuff. Are you attempting time travel?

 

About the TE, use lazy initialization. And keeping a strong reference to the other TE is a bad idea, it will cause memory leaks.

[ItsAMysteriousYT]

I have no idea what you are trying to say with the "no future yet" stuff. Are you attempting time travel?

 

About the TE, use lazy initialization. And keeping a strong reference to the other TE is a bad idea, it will cause memory leaks.

Oh HAHA no Must have been thinking of something else and wrote future What i wanted to ask is if there will be a world in readFromNBT later.

And for the tile - what you mean with lazy initialization? And also the tile need to know where to send the signal to or not im not connecting the two blocks with redstone or simillar blocklike structurs but just with cables that are rendered in the TESR if the tile. Thats why i need the 'to' variable in the class (if you mean that with strong reference )

[diesieben07]

I don't care if you think that you "need" the reference to the TE. Keeping it there is a bad idea. If the other chunk unloads you will keep the TE instance alive and you have created a memory leak. If the chunk is then loaded again the next problem arises: You now have a reference to the wrong (dead) TE instance.

 

For lazy initialization: Google.

[ItsAMysteriousYT]

OH - i think you just solved the whole thing - is it possible that when the chunk was unloaded and then loaded again - the empty 'to' field is set to any other TileEntity_Electric? And also the thing with storing coordinates worked THANKS <3

[ItsAMysteriousYT]

This is how my TileEntity_Electric looks now - please tell me how i have to fix it im so lost on this i have absolutly no idea what im doing wrong :'(

I read that lazy initalization stuff but i do not understand the use of it e an also - how should i pass over the energy to the connected tile when i do not have a field.

 

MAN -IM SO LOST

 

Diesieben07 what you mean? How do i have to use that lazy stuff ?

1) Why is this class abstract?

2) Why are you writing the block metadata to the description packet? (You're ignoring it when the packet arrives, too)

3) Your "connectTo" function is never called, making storedPos always null (unless its being called from another class you haven't posted)

4) Why are you getting the World and saving it to the local variable world when you have access to (and use!) worldObj?

5) Why are you using

Minecraft.getMinecraft().thePlayer

?

1. So classes that extend on it have the required methods (e.g) getMaxVoltag()

2. just copied that from here: https://github.com/TheGreyGhost/MinecraftByExample/blob/master/src/main/java/minecraftbyexample/mbe20_tileentity_data/TileEntityData.java

3. It is is called in an  ItemCable class like this

 

 

@Override

public ItemStack onItemRightClick(ItemStack stack, World world, EntityPlayer player) {

BlockPos pos = Minecraft.getMinecraft().objectMouseOver.getBlockPos();

RLMPlayerProps props = RLMPlayerProps.get(player);

if(world.getTileEntity(pos) instanceof TileEntity_Electric){

TileEntity_Electric toConnectTile = (TileEntity_Electric) world.getTileEntity(pos);

if(props.lastTile!=null&&props.lastTile!=toConnectTile){

props.lastTile.connectTo(toConnectTile);

world.markBlockForUpdate(props.lastTile.getPos());

props.lastTile=toConnectTile;

}

else{

player.addChatMessage(new ChatComponentText("Now in "+EnumChatFormatting.GREEN+"Connection Mode"+EnumChatFormatting.RESET+"To stop connecting, hold SHIFT+RIGHTCLICK! "));

props.lastTile = toConnectTile;

}

 

}else

{

if(world.getBlockState(pos).getBlock() instanceof BlockAir){

player.addChatMessage(new ChatComponentText("Stopped "+EnumChatFormatting.RED+"Connection Mode"));

props.lastTile=null;

}else

{

world.setBlockState(pos, RealLifeMod_Blocks.cable.getDefaultState());

}

 

}

return stack;

}

 

 

 

4: Just copied that too

5: cuz TileEntity hasn't got a ticksexisted field

[Draco18s]

1) ok, wasn't arbitrary. I still don't think you need to make the class abstract, but whatever.

2,4) Mmm...copy-pasta..

3) this method makes me cry.

 

5: cuz TileEntity hasn't got a ticksexisted field

 

And it will crash a dedicated server.  Good job.

 

So add one yourself.  It's got an update function, hasn't it?  You can create properties yes?  You can increment a counter in the update function, no?  Bloody freaking magic that is.

Okay i did this, but still, it does not work propperly. When i connect the blocks, the connected tile is the last tileentity in the circuitfor every tile in the circuit
