Lambda

Hey there, so I'm trying to find a way to detect 2 quartz blocks and a gold block on top, on each side.. However, I don't know how to get started. I could do EnumFacing.Horizontals , however finding the two blocks above the block that is detected by the forloop is where I'm stuck.. What would be the best way for the TE to detect if there is a 3 high structure (with the top of them being gold blocks) on each side.

Okay, so great progress, however, I'm trying to setup a 'default value' of the energy inside the chunk, however, I'm having a hard time doing so, I've tried making another IVoidStorage and VoidStorage classes that closely replicates the Energy ones, but in the constructor have the energy set to the capacity.. However, when doing this it seems the chunks return null when looking for the energy attached to it.. Maybe there is another way than creating another energy handler? Thanks.

Okay Thanks!

Hey there! So I'm having a bit of an issue with my IDE, it seems like a lot of lambda / diamond expressions are not allowed.. I've tried changing my project settings to match said language level, but it doesn't seem to solve anything... Thanks!

Thanks Animefan and Choonster! Its late, so I'm gonna go to bed and then study the code when I wake.. I'll maybe even post about explaining the code, to see if I get all parts correct. Happy New Year Everybody!

How can I access the map without accessing the capability?

Then how do you recommend I fix it?

@SubscribeEvent public void onChuckLoadEvent(ChunkDataEvent.Load event) { if(event.getWorld().hasCapability(CapabilityVoidEnergy.VOID, null)) { CapabilityVoidEnergyData cap = event.getWorld().getCapability(CapabilityVoidEnergy.VOID, null); cap.chunkData.put(event.getChunk().getPos(), cap.getVoidEnergyStored(event.getChunk().getPos())); } }

No, seems I get a nullpointer there: ---- Minecraft Crash Report ---- // Who set us up the TNT?

Havent fired up the client yet, but IDE no.

So this: @Override public int getVoidEnergyStored(ChunkPos pos) { return chunkData.get(pos); }

You will be getting an Integer. Yes I know that, but what would I put into the get method ( What obj ) A ChunkPos(your key). Did you read that link I sent you? Yes but I dont have access to a chunkPos.. Should include that in the parameters?

No, for several reasons. For one, the return of this.getPos() is a ChunkPos, you don't need to construct a new ChunkPos with it. Second, the return of cap.chunkData.get() is your value, which cannot be used as the key to put new data in. cap.chunkData.put(this.getPos(), /*new value*/); If you want to modify the value (not replace it), then cap.chunkData.put(this.getPos(), cap.chunkData.get(this.getPos()) + /*some modifier*/); Thanks for your detailed repose, however this.getPos() is a BlockPos not a ChuckPos, so I'll need to do construct it (this is inside a TE). You will be getting an Integer. Yes I know that, but what would I put into the get method ( What obj )

Yes I know, Thats the question, what should I be getting.

Okay for something like this: @Override public int getVoidEnergyStored() { return chunkData.get(); } What would I get?

Should I be accessing that map somewhere in my capability? Right now I have this: public class CapabilityVoidEnergyData implements IVoidStorage { protected int capacity; protected int voidStorage; protected int regen; public Map<ChunkPos, Integer> chunkData = new HashMap<ChunkPos, Integer>(); public CapabilityVoidEnergyData(int capacity, int voidStorage, int regen) { this.capacity = capacity; this.voidStorage = voidStorage; this.regen = regen; } @Override public void receiveVoidEnergy(int receive) { if(canReceiveVoidEnergy(receive)) { this.setVoidStorage(this.getVoidEnergyStored() + receive); } } @Override public void extractVoidEnergy(int extract) { if(canExtractVoidEnergy(extract)) { this.setVoidStorage(this.getVoidEnergyStored() - extract); } } public boolean canExtractVoidEnergy(float amount) { if((this.getVoidEnergyStored() - amount) >= 0) { return true; }else { return false; } } public boolean canReceiveVoidEnergy(float amount) { if((this.getVoidEnergyStored() + amount) <= this.getMaxVoidEnergyStored()) { return true; }else { return false; } } public NBTBase writeData() { NBTTagCompound tag = new NBTTagCompound(); return tag; } public void readData(NBTBase nbt) { } @Override public int getVoidEnergyStored() { return voidStorage; } @Override public int getMaxVoidEnergyStored() { return capacity; } public void setVoidStorage(int amount) { this.voidStorage = amount; } @Override public boolean canExtract() { return false; } @Override public boolean canReceive() { return false; } } And I'm not accessing the map value anywhere, should I just remove the 'voidenergy' integer, and just return the map value?

Okay, so why does modifying the values of the keys have to do with my 'energy'? I know I'm doing something wrong here: cap.chunkData.put(cap.chunkData.get(new ChunkPos(this.getPos()), /* new value */); Is this correct? If I'm getting this right, then when we assigned the map, ChuckPos is our key, which contains our x,y, and the integer part stores the x,y values? Correct?

Okay, thanks for that.. How would I get the energy value though... Yes it returns the value, however what would I do with said value?

What is the integer that it returns? the x/y value or the integer that I assigned in the Map?

Okay, how would I add / remove some 'energy' from a chunk, not all of them, current I have: cap.chunkData.get(new ChunkPos(this.getPos())); cap.receiveVoidEnergy(5); Which obviously doesn't work because I accessing all chunks with cap.receive... So how would I just do it for that chunk?

I see to be getting a NullPointer on: cap.chunkData.put(event.getChunk().getPos(), cap.getVoidEnergyStored()); with: ---- Minecraft Crash Report ---- // I'm sorry, Dave.

Do I have to assign the map? Or does the ChuckPos include all loaded chunks?

Well, you know Deep Resonance? How radiation works with the chunks being assigned values? I kinda want that, but a energy value stored to each one.. So I think i need to assign the data to each chunk

So do chunks work like gird coords? 0,0 1,0 2,0 0,1? And how would I iterate though all of them to assign the capability to them? And can I expose the capability with World#getChunkFromBlockCoords(BlockPos) , So I could access it though a TE?
