Because your instance fields are not saved. Because they shouldn't exist at all. 

how about instead of using update in tile entity, I use updateTick in block?

but if i do not make it instance there will be other problems. is there a way to create this instance field every time the game is reloaded?

You must acquire the TE from the world every time.

its something with your fireplasma method then... need a crash report. Tile gets created together with the block. what you’re doing with World#getTileEntity is just getting the tile entity that is on that pos

I missed a plasmacannon.getstate last time and caused the crash, I added it back and run the game again, although the game won't crash, power of the projectile does not change no mater how many iron blocks i add behind it.

OK, then i guess i should make an item that allows play to destroy old Plasma Cannon block and replace it with a new. And tell them to use it on Plasma Cannon every time the game is reloaded 

What? No. Christ.

 

Build two of your cannons near each other. Do they both work? I bet not!

OK you are right. But if I make the tile local, i don't get the updated powerfactor, it's always 0. 

actually before I use the update method for TileEntityPlasmaCannon, I acquire the TE locally in onBlockActivated. But because I'm planning on making this cannon stores IC2 energy and the more iron blocks attached behind it the higher maximum energy it can store, so I cannot use onBlockActivated to achieve that. And I really do not understand why if I use 2 local TEs in onBlockAdded and onBlockActivated it will stop updating power factor.

You should learn more about sides... for example you're using server side in onBlockAdded for TileEntityPlasmaCannon#getstate which means that data isn't stored on the client, if you need it on the client you have to send a packet to the client or just get rid of 

if (!worldIn.isRemote)

and make TileEntityPlasmaCannon#getstate be started on both sides. You're also updating the TileEntityPlasmaCannon.powerfactor on server side only... thats why there's nothing on client side (its always 0)... also you're just making your code 4 times bigger because you're not using

Also, I seriously hope all those special cased directions are a joke. EnumFacing specifically exists so you can do for example BlockPos#offset(EnumFacing).

I know this is gonna be kind of annoying but you should learn more java... trust me I've been where you are now 2 years ago but now I'm a lot better.

Do you know some built in forge codes that can help me synchronization server and client? I wanna synchronize the powerfactor in onBlockActivated.

Thank you! I'm now trying to work on it, and I'll ask you questions here since this thread is not old.

would you tell me which specific data you are synchronizing? or it updates every data of TileEntityBase to client? I do think I need more explanation.

I'm syncronising all my Capability Data >

I'm getting the capabilities through the custom methods getInventory(), getEnergy() and getFluid() (or whatever the fluid capability getter is called, I've never used it) then writing the capabilities to NBT and sending that NBT to the client.

does it matter if i use ic2 energy instead of forge energy?

1 minute ago, Ice2670 said:

potentially, I made a small effort to add support for non FE systems that use IEnergyStorage a while ago but never tested it. If the code that edited works it shouldn't be an issue if IC2 is using capabilities and implementing Forge's IEnergyStorage

OK, now the synchronization problem is solved thanks to Draco18s and Cadiboo, gonna post codes here

public void readFromNBT(NBTTagCompound nbt){
    super.readFromNBT(nbt);

    if (nbt.hasKey("energy"))
    {
        this.energy = nbt.getDouble("energy");
    }

}

@Override
public NBTTagCompound writeToNBT(NBTTagCompound nbt) {
    super.writeToNBT(nbt);
    nbt.setDouble("energy", this.energy);
    return nbt;
}

@Override
@Nullable
public SPacketUpdateTileEntity getUpdatePacket() {
    return new SPacketUpdateTileEntity(this.pos, 3, this.getUpdateTag());
}

@Override
public NBTTagCompound getUpdateTag() {
    return this.writeToNBT(new NBTTagCompound());
}

@Override
public void onDataPacket(NetworkManager net, SPacketUpdateTileEntity pkt) {
    super.onDataPacket(net, pkt);
    handleUpdateTag(pkt.getNbtCompound());
}

private IBlockState getState() {
    return world.getBlockState(pos);
}

and in update

public void update()
{

    EnergyTileLoadEvent loadEvent = new EnergyTileLoadEvent(this);
    MinecraftForge.EVENT_BUS.post(loadEvent);
    
    //these are for synchronazation
    world.markBlockRangeForRenderUpdate(pos, pos);
    world.notifyBlockUpdate(pos, getState(), getState(), 3);
    world.scheduleBlockUpdate(pos,this.getBlockType(),0,0);
    markDirty();
    


}

all these are added to TileEntityPlasmaCannon. I just copied the codes Draco18s provided here

Please don't just copy code, read through it and learn how it works, if you don't understand how something works ask questions.

to understand synchronization requires deep understanding on java, but right now i do not have time to go through such complicated problem. how ever I do understand how to use the codes provided by Draco18s.

 

As for the whole problem, I update powerfactor every time in fireplasma method instead of in update method, than the game won't crash.

 

And if possible, would you explain what does

 

world.scheduleBlockUpdate(pos,this.getBlockType(),0,0);
markDirty();

do?

Energy will always be an integer, not a double.

no, EU energy is double

Forge's IEnergyStorage only allows integers. If its a double then they're using a different system from the one that I use and know about, and you should google some tutorials for it.

Do you have a GitHub I can look at?

not yet, but the energy works just fine, i already tested it.

if you want to know how ic2 energy is different i suggest you check on ic2 source codes, but my codes that involves energy use is here

public void update()
{
    EnergyTileLoadEvent loadEvent = new EnergyTileLoadEvent(this);
    MinecraftForge.EVENT_BUS.post(loadEvent);
    world.markBlockRangeForRenderUpdate(pos, pos);
    world.notifyBlockUpdate(pos, getState(), getState(), 3);
    world.scheduleBlockUpdate(pos,this.getBlockType(),0,0);
    markDirty();
}



public void invalidate()
{
    EnergyTileUnloadEvent unloadEvent = new EnergyTileUnloadEvent(this);
    MinecraftForge.EVENT_BUS.post(unloadEvent);
}

@Override
public double getDemandedEnergy() {
    return this.maxenergy - this.energy;
}

@Override
public int getSinkTier() {
    return Integer.MAX_VALUE;
}

@Override
public double injectEnergy(EnumFacing directionFrom, double amount, double voltage) {
    if (this.energy >= this.maxenergy) return amount;

    double openEnergy = this.maxenergy - this.energy;
    if (openEnergy>= amount)
    {
        this.energy += amount;
        return 0.0D;
    } else if (amount > openEnergy)
    {
        this.energy += openEnergy;
        return amount - openEnergy;
    }

    return 0;
}

@Override
public boolean acceptsEnergyFrom(IEnergyEmitter emitter, EnumFacing side) {
    return true;
