You are trying to replace the blocks in your block's constructor.

 

There are two problems with this:

 

1) The constructor happens before the game has reached the main menu

2) You are trying to access methods of a null object.  That is, your world variable is declared but not defined.  For obvious reasons.  Not to mention that i, j, and k are also null!

 

You should be doing this code either onEntityCollidedWithBlock or onBlockActivated or similar.  Where the world is passed to your block class.

[Yagoki]

You may want to take a look at your variables i j and k, This may be causing your null pointer. Also, be careful using static variables here because you could get problems concerning threading. Try putting this into the block or a TileEntity instead as a local method and pass it the required parameters through the method.

 

Personally i'd also suggest (just as a bit of cleanup) that you reuse your parX variables so you only have one, and reassign it new values, this will just free up a small amount of memory space and make things look nicer.

 

public class MyTE extends TileEntity
{
    @Override
    public void onUpdate()
    {
        if(this.worldObj.isBlockIndirectlyGettingPowered(xCoord, yCoord, zCoord))
        {
            int id = this.worldObj.getBlockId(xCoord+1, yCoord, zCoord);
            if(id==1)
                world.setBlockId(xCoord+1, yCoord, zCoord, 0);
            id = this.worldObj.getBlockId(xCoord+1, yCoord+1, zCoord);
            if(id==1)
                world.setBlockId(xCoord+1, yCoord+1, zCoord, 0);
            //and so on
        }
    }
}

He is calling this from his block, in the on neighbor block changed, so it is called only when the block is in the world

2013-06-16 02:08:03  [sTDERR]    at huntingTraps.Traps.Pitfall.onNeighborBlockChange(Pitfall.java:29)

however yes he should be doing it in his block/tileEntity

[dontrell94]

I am indeed throwing this method only when needed by another block. this is my attempt at only changing certain blocks.

 

I'm trying to write the coordinates to a variable then have the file each variable checked against certain id numbers. if it is on a predetermined list then it gets turned to air.

[Draco18s]

Just so you know:

 

par12 == (1|2|3|4|12|13)

 

That won't do what you think it does.

 

1|2|3|4|12|13 == 16.

[dontrell94]

how do i do or?

[Draco18s]

how do i do or?

 

par12 == 1 || par12 ==2 || par12 == 3...

 

This is a fundamental basic understanding of programming.  The fact that you had to ask this question means you're not actually ready to mod Minecraft.

Another of the many shortcomings of Java. With Python, you can do

if par12 in (1,2,3,4,12,13):
    #stuff

[dontrell94]

par12 == 1 || par12 ==2 || par12 == 3...

No I'm still learning as I go, I forgot about that.......I feel stupid

[dontrell94]

*bump*

 

any ideas? the error happens right when i activate the block, it happens with just the variable being written to, before any action happens.

[Mew]

I feel like a know all in this situation...

 

try something like this:

package huntingTraps.Resources;

import net.minecraft.world.World;

public class PitfallHandler
{  
    public static World world; // the world you are using
    public static int i, j, k; // X, Y, and Z axis variables

    public PitfallHandler(World world, int x, int y, int x)
    {
        this.world = world; // the world
        this.i = x; // X axis
        this.j = y; // Y axis
        this.k = z; // Z axis
    }
    
    public static void generatePitfall()
    {
        // this nested for loop will make a 'block' of air to the dimensions specified in numOfBlocksOn***
        for(int x = 0; x < numOfBlocksOnXAxis; ++x)
        {
            for(int y = 0; y < numOfBlocksOnYAxis; ++y)
            {
                for(int z = 0; z < numOfBlocksOnZAxis; ++z)
                {
                    world.setBlock(
                       i + x, // this makes blocks of air go out however many numOfBlocksOnXAxis was
                       j - y, // this makes blocks of air go out however many numOfBlocksOnYAxis was
                       k + z, // this makes blocks of air go out however many numOfBlocksOnZAxis was
                       00 // the block of air
                       );
                }
            }
        }
    }
}

 

Then in the onBlockActivated() method, have something like this inside it:

PitfallHandler pit = new Pitfallhandler(Minecraft.getMinecraft().theWorld, (location of block x, y and z coords in the next 3 paramaters) xLocation, yLocation, zLocation);
pit.generatePitfall();

 

I garuntee that the PitfallHandler will work, the other... well

[ObsequiousNewt]

I feel like a know all in this situation...

Don't worry, Mew, we all do.

[atrain99]

I feel like a know all in this situation...

 

try something like this:

~snip~

 

 

I garuntee that the PitfallHandler will work, the other... well

 

I think the NPE you're getting comes from code order.

 

If you can single-step the code at the function, you can find the exact point where the NPE is thrown.

[dontrell94]

mew, thats essentially what the original code for this mod is, i'm trying to get it to detect certain block ids and only delete them

[Yagoki]

then surround

world.setBlock(
                       i + x, // this makes blocks of air go out however many numOfBlocksOnXAxis was
                       j - y, // this makes blocks of air go out however many numOfBlocksOnYAxis was
                       k + z, // this makes blocks of air go out however many numOfBlocksOnZAxis was
                       00 // the block of air
                       );

with

if(world.getBlockId(i+x, j-y, k+z) == Block.stone.blockId)//or whatever blockId you want

[dontrell94]

mew's code doesn't work properly, i'm messing with it

[dontrell94]

all it does it make them invisible and semi non existent....

[Draco18s]

Just as an FYI on Mew's code.

 

Don't make x y and z static...or hell, even the world (there's a different world object for each dimension!)

 

As soon as you have two of these suckers placed things will Go Weird.

[dontrell94]

It didn't look right as static, so mine isn't

[Draco18s]

It didn't look right as static, so mine isn't

 

Are you passing them to generatePitfall()?  Or are you pretending that they get magically set every time you want to use them?

That is:

Dynamic class-level variables aren't going to fix it alone.

[dontrell94]

Tell me if i'm wrong....

I'm surprised this didn't throw an error.  You don't have enough parameters.

 

world.setBlock(

                                j - y, // this makes blocks of air go out however many numOfBlocksOnYAxis was
                                k + z, // this makes blocks of air go out however many numOfBlocksOnZAxis was
                                00, // the block of air
                                3 //tells the client and server that a block update is required.
                                );

[dontrell94]

double check cuz it throws an error if I put it your way.

[Draco18s]

My bad.

Ever since they changed things from "setBlock/setBlockWithNotify/setBlockAndMetadata/setBlockAndMetadataWithNotify" to only one function (actually, two) they've thrown me for a loop.

 

You are correct, yours works and passes an implied metadata of 0 and a notify flag of 3.

 

Just out of curiosity:

You are doing this with the block on top of stone, yes?  It's only clearing a 2x2x2 cube at the moment, and only stone.

 

(Side note:

new PitfallHandler(Minecraft.getMinecraft().theWorld, i, j, k);

You can just use:

new PitfallHandler(world, i, j, k);

As the world is passed to the neighborChanged function)

[dontrell94]

essentially 3 blocks below this plus the row its on
