Having a crash when loading a would with the block in...

 

 

Sorry about it not being in the code thingy, it would not let me use it or the spoilers or anything

Stacktrace:

at net.minecraft.entity.item.EntityItem.<init>(EntityItem.java:62)

at net.gammas.magicas.models.TileEntityEssenceExtractorRenderer.renderTileEntityAt(TileEntityEssenceExtractorRenderer.java:55)

 

if ((entItem == null) || entItem.getEntityItem().getItem() != tileEntity.getStackInSlot(slot).getItem())
         entItem = new EntityItem(tileEntity.getWorldObj(), x, y, z, tileEntity.getStackInSlot(slot));

If

tileEntity.getStackInSlot(slot)

returns

null

, it will crash when calling

getItem()

on

null

.

to insert code, type the following without the : 

[co:de]
your code here

 

[spoi:ler]

your console data here

[/spoi:ler]

 

it's bbcode, there are reference websites around.

 

p.s. I am having crashes while trying to render items on blocks in 1.8, too.  It's hard.

I just stopped my mod from crashing when there's a null slot on my shelfblock (i.e. trying to render an empty item) by checking to make sure it's not null before doing the render.

 

however, it still doesn't render my items and when I remove them from my ShelfBlock storage slots, they disappear.  I must have broken something and not gotten the rendering right.
