I would like to preemptively say I'm sorry I am newish to forge modding, I seem to have come to a stump and can not find the answer in the forums. But My problem is that when one block gets updated with redstone all blocks of the same Id seem to get updated as well, while I Only want a single one(the one seeing redstone) to be updated.

 

The Block Code is As Follows:

 

public static boolean laserState = false;

public void onNeighborBlockChange(World world, int x, int y, int z, int l)
    {
	 if(BlockGlassBase.BaseHasGlass)
	 {
        if (world.isBlockIndirectlyGettingPowered(x, y, z))
        {
        	this.laserState = true;
        	this.setLightValue(0.8f);
        	
        }
        else
        {
        	this.laserState = false;
        	this.setLightValue(0.0f);
        }
	 }
    }

 

The TileEntity Code is As Follows:

 

@Override
    public void updateEntity()
{
	if(BlockGlassLaser.laserState)
	{

        if(!worldObj.isRemote){
        	LaserParticleEffects.spawnParticle("test", this.xCoord+0.5f, this.yCoord-0.1f, this.zCoord+0.5f, 1.5D, -0.1D, 1.5D);
        }
	}
        super.updateEntity();
    }

 

I tried many different things to get this to work from having a incrementing int in the block constructor for an associated id per block but every block was only 1 suggesting all were made at the same time when I logged in() I also tried having the laserState variable in the TileEntity Class and from the block class running a function that was located in the TileEntity Class that set its state but to no avail it also updated all blocks as well. I'm probably noobing it up but please help!

Maybe you can use metadata or both the on state and the off state?

Mmmm, static. <3

(I love scope.  This is the fourth thread in the last two days that has had the same problem.)

In minecraft there is only one Block instance for each type. So you have to change metadata for your goal. Use world.setBlockMetadataWithNotify.

ok, thanks. I will definitely give that a try.

It seems I must make a separate Block Id For This, I was thinking something like this would be promising:

 

if(world.isBlockIndirectlyGettingPowered(i, j, k))
                                {
                                                if(blockID == CLASS.laserStateOff.blockID)
                                                {
                                                        world.setBlockMetadataWithNotify(i, j, k, CLASS.laserStateOn.blockID);
                                }
                                else
                                {
                                                world.setBlockMetadataWithNotify(i, j, k, CLASS.laserStateOff.blockID);
                                }
}

 

My other question though with this is whether I might need to use world.setBlockMetadataWithNotify(i, j, k, CLASS.laserStateOff.blockID); for the original constructors as well or if just having it as above should be fine?

Well I was able to finally solve this but was unable to get it working via metadata(probably due to my lack of knowledge on custom TileEntity Blocks and metadata) My method of solving this was to merely create a second Block that had the particle render in its own tileentity.

ex:

public void onNeighborBlockChange(World world, int i, int j, int k, int l)
    {
        if (world.isBlockIndirectlyGettingPowered(i, j, k))
        {
        	world.setBlock(i,j,k,Blocks.blockGlassLaserOn.blockID);
        }
    }

 

and then on the other block I merely reversed it.

public void onNeighborBlockChange(World world, int i, int j, int k, int l)
    {
        if (!world.isBlockIndirectlyGettingPowered(i, j, k))
        {
        	world.setBlock(i,j,k,Blocks.blockGlassLaser.blockID);
        }
    }

 

though I did not want to do this as it creates issues with if the player left it in the on state and were to restart the client/server it would crash cause it calls the particle render too fast and sees a nullpointer So If anyone knows of a way to fix this? or maybe set a block in the world with an id=blockGlassLaserOn.blockID To the default off state when the server/client is first loaded so it will not crash. I think atm though I can fix it by setting a bool in the load event to false and set it to true when the default block gets power although this is unfortunate as the player will have to turn it off and back on again in the case they left it in the on position when they quit the client/server

 

world.setBlockMetadataWithNotify(i, j, k, CLASS.laserStateOn.blockID);

That method set the block metadata, according to the last parameter given. Do you know the metadata range is [0,15] ?

ah ok, that might have been what was happening. I will retry that then.

Well I was finally able to get back to coding and yep, merely setting the metadata values below 15 worked TY! In the tileentity I now just check for this.getMetadata. which works great! and for the crashing issue I just use this.metaData = 0; inside the tileentity constructor and that resets it to 0 when the game is freshly loaded.

Example:

 

Block Class

public void onNeighborBlockChange(World world, int i, int j, int k, int l)
    {
	 System.out.println("neighbor Event ran");
        if (world.isBlockIndirectlyGettingPowered(i, j, k))
        {
        	world.setBlockMetadataWithNotify(i, j, k, 2,3);
        }
        else
        {
        	world.setBlockMetadataWithNotify(i, j, k, 0,3);
        }
    }

TileEntityClass

public TileEntityGlassLaser()
{
	this.blockMetadata = 0;
}
@Override
    public void updateEntity()
{
	if(this.getBlockMetadata() == 2)
	{
        if(!worldObj.isRemote){
        	LaserParticleEffects.spawnParticle("test", this.xCoord+0.5f, this.yCoord-0.1f, this.zCoord+0.5f, 1.5D, -0.1D, 1.5D);
        }
	}
        super.updateEntity();
    }

 

TY Everyone!
