here is some video of it, please not it does the same thing with iron ore from vanilla so......

 

 

 

here is a link to my project on github:

 

https://github.com/hihellobyeoh/Advanced-Tunnelboring

 

please help me fix it

It's caused by a typo I think!

 

From TileEntityBlastFurnace.java, lines 240 - 242:

 

if(this.furnaceItemStacks[0].stackSize >= 0){ // If the ItemStack contains zero or more items
   this.furnaceItemStacks[0] = null; // Set the ItemStack to null
}

 

Now I know you might not know where the source of any given error in your project is, but linking to your entire project kind of comes off as "Here's my project, now fix it for me!" I doubt that's the impression you intended to give, but that's the one I got. Just something to consider.

no it was because of last time i posted on here it was erroring on one file but the problem causing it was in another file but yeah i was looking at that line and to me i thought it was fine, but my brain is half dead right now so idk.... thanks

ok i changed it to this:

f(this.furnaceItemStacks[0].stackSize == 0){ // If the ItemStack contains zero or more items
   this.furnaceItemStacks[0] = null; // Set the ItemStack to null
}

 

and now it is working, i checked on the guy who's tutorial i was following and his is still showing what my code was, so i didn't do it wrong, so much as he game me incorrect code
