Need Help With Creating A Multiblock Structure [1.7.10] [SOLVED... For now]

[TheEpicTekkit]

I need help with creating A multiblock structure. I have the code that checks if all the blocks are in the correct formation, but that is about it, I dont know what to do from here. Also, another thing I have no idea how to even start is all the blocks in the structure open the same inventory, you dont have to click a specific block in the structure to open the gui, and the inventories are synchronised with eachother so that if you open the gui from one block and add items, the gui from a different block has the same items as long as it is in the same structure.

 

This is the code I have that checks if the structure is correct (Warning, very long, the structure is large, 5x5x10)

 

 

        public boolean checkMultiBlockForm() {
	int x = this.xCoord;
	int y = this.yCoord;
	int z = this.zCoord;
	Block block = BlockHandler.distillationChamber;

	if (worldObj.getBlock(x+1, y, z) == block) {
	if (worldObj.getBlock(x+2, y, z) == block) {
	if (worldObj.getBlock(x+1, y, z+1) == block) {
	if (worldObj.getBlock(x, y, z+1) == block) {
	if (worldObj.getBlock(x, y, z+2) == block) {
	if (worldObj.getBlock(x-1, y, z) == block) {
	if (worldObj.getBlock(x-2, y, z) == block) {
	if (worldObj.getBlock(x, y, z-1) == block) {
	if (worldObj.getBlock(x, y, z-2) == block) {
	if (worldObj.getBlock(x+1, y, z-1) == block) {
	if (worldObj.getBlock(x+2, y, z+1) == block) {
	if (worldObj.getBlock(x+1, y, z+2) == block) {
	if (worldObj.getBlock(x+2, y, z-1) == block) {
	if (worldObj.getBlock(x-1, y, z+1) == block) {
	if (worldObj.getBlock(x-1, y, z+2) == block) {

This code is in the tileentity

 

I also want the container of this block to be able to store liquids, any ideas on how to make an inventory store liquids?

 

Thanks for the help.

[TheEpicTekkit]

Okay, so I have just tested it by making it print in the console "Multi Block Structure Successfully Formed In TileEntity" if the formation is correct, and it works perfectly. Now what do I do from here?

[Black]

Well, to start of with, replace about 300 of those if statements with a few nested for loops. It'll clean your code up a lot.

 

Secondly, there are several methods to do the things you asked.

One way is all but one block are dummy blocks and simply reference the main block and its inventory, right click etc.

Second way, make them all real blocks but each has a reference of the original block as to interact with it.

 

So basically you always need one main block and every other block interacts with it. This doesn't mean those blocks can't do anything but the things that have to be the same everywhere will use that.

 

However do NOT attempt the following:

Make all blocks identical, and constantly update each other, you're wasting too much cpu that way. You can use the same block though, just make a block and if it is in the correct position(for instance in the bottom middle if it is a 3x3 at the bottom(it can detect another block there and has the same block around it) and simply let it behave as the core block, if isn't in that spot let it behave as a fake block.

[TheEpicTekkit]

Okay, thanks for that, I'll try this. Also, how would I make a for loop check a 5x5x10 space and what do you mean by a nested for loop?? I have never heard of that (probably should have....)

 

And have you got any idea on how to make the inventory be able to store liquids? this whole multiblock is going to turn crude oil into petroleum, diesel, propane, tar, and butane (6 liquids I have already added)

[Eternaldoom]

Nested for loops are for loops inside of other for loops.

[TheEpicTekkit]

Ah, ok, that makes more sense now, so would I have a for loop for x pos, y pos, and z pos?

[Black]

Nope, you use whatever is most useful, logical and lets you compact as much as possible without doing extra loops or non-related numbers.

In minecraft however, this is often, and also here, the xyz.

[TheEpicTekkit]

Okay, now, how do I make all the dummy blocks reference the main block (bottom centre) I know that black said:

So basically you always need one main block and every other block interacts with it. This doesn't mean those blocks can't do anything but the things that have to be the same everywhere will use that.

 

But how would I do this? I have had alot of trouble referencing other tileentities before

 

 

[Black]

Like this:

 

TileEntity Tile = parWorld.getTileEntity(parCoordinateX, parCoordinateY, parCoordinateZ);

[TheEpicTekkit]

Okay, Thanks

[TheEpicTekkit]

Now, any ideas on how I can make the inventory store liquids?

[Black]

Well, I'm not going to write this mod for you know, you'll have to do your own research.

 

There are several methods but the best way I believe is

that you can increment a counter if you've found the correct liquid and deleted it(whether as item or block).

Then if you need to make the liquid come out again you decrement the counter and spawn a liquid block at the correct coordinates.

Since the core block is obviously a tile entity, simply save the counter in nbt.

 

[TheEpicTekkit]

Okay, thanks once again. I'll do this.

[TheEpicTekkit]

Okay... I have been trying to figure this out for an hour now... my game crashes when I open the gui.

 

This is the crash report:

Now I know it is nothing to do with the actual container or gui because the gui was working perfectly fine before I made it check if the structure is properly formed, It opened, I could place items inside, it closed etc wothout a problem

 

I have the feeling that it is something really obvious that I have missed.

Also...

Like this:

 

TileEntity Tile = parWorld.getTileEntity(parCoordinateX, parCoordinateY, parCoordinateZ);

 

This wont let me reference variables in the tileentity class like if the multiblock is formed.

Allright,

 

First of all the error log (reading that thing actually helps, who knew)

Caused by: java.lang.NullPointerException
at net.theepictekkit.generator.common.tileentity.TileEntityDistillationChamberFrame.checkMultiBlockForm(TileEntityDistillationChamberFrame.java:53)

This line tells you that at line 53 of the file and in the method checkMultiBlockForm a nullpointerexception is occuring. E.g. You're asking an object and a null is returned.

Go to that line and find out why you're not getting what you're asking.

 

Secondly:

The line I gave you puts the TileEntity in a variable of type TileEntity. It's quite obvious it can't call methods that are only known by its subclass.

A solution is a simple reflection. Replace TileEntity with the class you want to access (granted it inherits the Tileentity class some way or another) and place that same class in round brackets just after the '='. Example:

 

TileEntityDistillationChamberFrame Tile = (TileEntityDistillationChamberFrame) parWorld.getTileEntity(parCoordinateX, parCoordinateY, parCoordinateZ);

 

Thirdly:

 

I didn't notice this before but this might possibly be the longest line of closing brackets I have seen that are actually useful, and I have seen quite a bit of code already.

Okay, I did read the error log, and I did go to line 53 in the tileentity, and that was the first if statement:

if (worldObj.getBlock(x, y, z) == main) {

This could not possibly be null because one: this is the main block in the structure that actually stores the data, and it is the actual blockDistillationChamber that has the onBlockActivated method that is causing the error. and two: if it were null, the structure would not be formed, and I know it is formed because when it is, it prints in the console that it is formed. And I have tested this, it only prints that if it is actually formed, it isn't a false reading.

 

and I also looked at line 58 in BlockDistillationChamber and that was:

if (!tileEntity.checkMultiBlockForm()) {

 

I did say that I have spent about an hour trying to figure this out, and the first thing I did was read the crash report to see if I could locate the error.

[TheEpicTekkit]

Nevermind. I got it working.

 

I changed:

TileEntityDistillationChamberFrame tileEntity = new TileEntityDistillationChamberFrame();

 

to:

TileEntityDistillationChamberFrame tileEntity = (TileEntityDistillationChamberFrame)world.getTileEntity(x, y, z);

 

So it was a problem with the way I was getting the tileentity.

lol.... yeah..... it is a messy bit of code.... but I diddnt want to do the for loop thing because I felt like this was more specific to what blocks needed to be where. The structure is quite a specific shape.... and btw, there is 129 if statements there...
