[1.7.2] TileEntityness

[Pardeep]

I have this mod that adds something very closely related to the furnace (in function terms, i.e. it smelts something and when that happens, it changes its texture and emits light) and in code terms (it's more or less furnace code tweaked). When I use it in single player, it works 100% fine.

 

However in a server, the following log appears.

Error log of server:

The BlockSteelifier line pointed to is:

par1World.setBlock(par2, par3, par4, FreshPower.getBlock("fp_steelifierActive"));

under the method

public static void updateFurnaceBlockState(boolean par0, World par1World, int par2, int par3, int par4)

 

The TileEntitySteelifer line is:

BlockSteelifier.updateFurnaceBlockState(this.furnaceBurnTime > 0, this.worldObj, this.xCoord, this.yCoord, this.zCoord);

under the method

public void updateEntity()

 

I think the error log has something to do with the entity updating. The error occurs when the block has sufficient stuff in the slots to "smelt". But nothing smelts, the block doesn't change to the illuminated one and this error pops up. Moments after, I get kicked out server given a TimeOutException.

Anyone know how to fix this. I know this code pointed at is identical to the BlockFurnace one, so I was wondering if vanilla Minecraft has a way of dealing with this for the vanilla Furnace and therefore available for me to use.

 

Thanks in advance.

Do you remember if you messed with

if (!this.worldObj.isRemote) 

in your

TileEntitySteelifer

class?

 

As I understand it, the (!this.worldObj.isRemote) is needed to keep the client and server objects in the right places; if that is not in the right place, objects won't be available where they are needed.

 

I had a tough time getting my mod elements all to behave well between client and server if that was not used appropriately. (I still don't yet completely understand it.)

 

I would have suggested your getBlock() function, but if it worked in single player, your

FreshPower.getBlock("fp_steelifierActive")

should be working correctly.

 

What does your getBlock() function look like?

Hi

 

The problem is caused by this line on the server

FreshPower.getBlock("fp_steelifierActive")

 

For some reason your getBlock is returning null.

Thank you both. I figured it out now. My getBlock() method was returning null. I got it pointing in the right direction in the end. Thank you again.

And @mjhotdog, I don't think there were many or any for that matter of those isRemote booleans in the vanilla code, but thanks for mentioning this as usually I miss these out.
