INTENSS

I switched up the method so it looks like this... private void infuseItem() { if (!canInfuse()) { return; } ItemStack itemstack = InfusionRecipes.getInfusionResults(slots[1].getItem(), slots[2].getItem()); if (slots[3] == null) { slots[3] = itemstack.copy(); } else if (slots[3] == itemstack) { this.slots[3].stackSize++; } for (int i = 0; i < 2; i++) { if (slots[i].stackSize <= 0) { slots[i] = new ItemStack(slots[i].getItem()); } else { slots[i].stackSize--; } if (slots[i].stackSize <= 0) { slots[i] = null; } } } It resolved the crash, however now it will burn fuel but not create the item but that is more than likely in my recipes class so i can figure that out. You were right Belpois, thanks for the help.

I went and reviewed the vanilla smeltItem method and clipped in the the section of code that decreases stack size to see if it was in fact my loop crashing and its not. with the vanilla smeltItem method it crashed when trying to decrease the stack size. as for the setFull3d 'm honestly not sure why i put that in there lol is removed though its not needed. method with error causing line pointed out. private void infuseItem() { if (canInfuse()) { ItemStack itemstack = InfusionRecipes.getInfusionResults(slots[1].getItem(), slots[2].getItem()); if (slots[3] == null) { slots[3] = itemstack.copy(); } else if (slots[3].getItem() == itemstack.getItem()) { this.slots[3].stackSize += itemstack.stackSize; // Forge BugFix: Results may have multiple items } for (int i = 0; i < 2; i++) { if (slots[i].stackSize <= 0) { // < --------------------------------------------------------------------------------------------------- CRASH IS ON THIS LINE slots[i] = new ItemStack(slots[i].getItem()); } else { slots[i].stackSize--; } if (slots[i].stackSize <= 0) { slots[i] = null; } } } } Crash Report ---- Minecraft Crash Report ---- // Oops.

I'm getting a ticking block entity error from this method below I know this is where is coming from. Its coming from the for loop. Now I'm building a dual input machine and I'm not sure if I'm doing this correctly. I'm looping through the fuel, and 2 input slots. Now I also have 3 upgrade slots. should I be looping though and checking ALL slots and not just the fuel and 2 inputs? The loop is whats crashing out the game and I'm just not sure if I'm writing it correctly or I'm just not checking what i need too. I can supply the rest of the code if needed but everything worked perfectly until I wrote this method. private void infuseItem() { if (canInfuse()) { ItemStack itemstack = InfusionRecipes.getInfusionResults(slots[1].getItem(), slots[2].getItem()); if (slots[3] == null) { slots[3] = itemstack.copy(); } else if (slots[3].getItem() == itemstack.getItem()) { this.slots[3].stackSize += itemstack.stackSize; // Forge BugFix: Results may have multiple items } for (int i = 0; i < 2; i++) { if (slots[i].stackSize <= 0) { slots[i] = new ItemStack(slots[i].getItem().setFull3D()); } else { slots[i].stackSize--; } if (slots[i].stackSize <= 0) { slots[i] = null; } } } } any help would be appreciated.

thank you deadrecon98 I COMPLETELY overlooked that and it fixed my issue. I went over the code, heck I don't know how many times and simply missed it. I tried creatTileEntity just to test it and that did not work just wanted to let you all know, at least not the with the way I have things configured. Thanks for all those who replied.

I'm working on a new machine and when I go to create the createNewTileEntity() method its keeps giving me and error must override or implement a supertype method I've never had this happen with any other machine I've built in the past and I'm plugging along in the same order of writing as I do with every machine. I'll post my block class and my Tileentity class below. Now neither one of them are finished all the methods needed to get this Gui to work should be completed. I can post the gui, handler, and container classes if needed but this error has to do with calling the tile entity. and YES everything is registered. and help would be appreciated block class: import java.util.Random; import AdvancedEnergy.Main; import AdvancedEnergy.tileentities.MetallicInfuserTE; import AdvancedEnergy.tileentities.OreProTE; import cpw.mods.fml.common.network.internal.FMLNetworkHandler; import cpw.mods.fml.relauncher.Side; import cpw.mods.fml.relauncher.SideOnly; import net.minecraft.block.Block; import net.minecraft.block.material.Material; import net.minecraft.client.renderer.texture.IIconRegister; import net.minecraft.entity.EntityLivingBase; import net.minecraft.entity.item.EntityItem; import net.minecraft.entity.player.EntityPlayer; import net.minecraft.inventory.Container; import net.minecraft.inventory.IInventory; import net.minecraft.item.Item; import net.minecraft.item.ItemStack; import net.minecraft.nbt.NBTTagCompound; import net.minecraft.tileentity.TileEntity; import net.minecraft.util.IIcon; import net.minecraft.util.MathHelper; import net.minecraft.world.World; public class MetallicInfuser extends Block { private final Random ran = new Random(); private final boolean isActive; private static boolean keepInventory = false; @SideOnly(Side.CLIENT) private IIcon iconTop; @SideOnly(Side.CLIENT) private IIcon iconFront; public MetallicInfuser(boolean state) { super(Material.iron); this.isActive = state; } @SideOnly(Side.CLIENT) public void registerBlockIcons(IIconRegister register) { this.blockIcon = register.registerIcon("ae:infuser_side"); this.iconFront = register.registerIcon(this.isActive ?

I resolved the issue on my own. I was calling my inactive furnace in my main registry AND in the block class itself. removed the from the class and called it off the main registry and everything work perfect.

Any ideas? Anyone...

I don't get it I have the idle and active blocks registered and intialized.. any ideas as to what might be causing that? I can post all the class files for the furnace if that's what it takes public void preLoad(FMLPreInitializationEvent event) { // Register Items MagnesiumDust.loadItem(); MagnesiumIngot.loadItem(); // Register Blocks // machines magFurnaceIdle = new MagFurnace(false).setHardness(3.5F).setBlockName("MagFuranceIdle").setCreativeTab(MainRegistry.btpTab); magFurnaceActive = new MagFurnace(true).setHardness(3.5F).setLightLevel(0.875F).setBlockName("MagFurnaceActive"); // Register Armor // Register Tools // Register Weapons GameRegistry.registerBlock(magFurnaceIdle, "MagFurnaceIdle"); GameRegistry.registerBlock(magFurnaceActive, "MagFurnaceActive"); /* GameRegistry.registerWorldGenerator(new WorldGeneration(), 0); */ GameRegistry.registerFuelHandler(new FurnaceFuel()); }

Thanks for replying, I noted the lines in the code snipplets but that is kind of tough to see so here they are. updateEntity(): if (flag != this.burnTime > 0) { flag1 = true; MagFurnace.updateFurnaceBlockState(this.burnTime > 0, this.worldObj, this.xCoord, this.yCoord, this.zCoord); // report points to this line } updateFurnaceBlockState(): if (state) { worldObj.setBlock(xCoord, yCoord, zCoord, MagFurnaceActive.magFurnaceActive); // report points to this line } else { worldObj.setBlock(xCoord, yCoord, zCoord, MagFurnaceIdle.magFurnaceIdle); } Hope that helps I can provide whatever else that may be needed

I had an issue with my furnace crashing the game when breaking the block while it was active or had been active. I fixed that issue however it seems another issue has come up with my updateEntity() method in my TileEntity class & in my updateFurnaceBlockState() method in my main block class. The crash report points out 2 lines of code 1 in each method, I'll post the full methods below and note the lines the report says is an issue. I didn't want to get on here and ask but I've been trying to figure this out since yesterday am starting to pull my hair out. updateEntity() method in my TileEntity class: public void updateEntity() { boolean flag = this.burnTime > 0; boolean flag1 = false; if (this.burnTime > 0) { --this.burnTime; } if (!this.worldObj.isRemote) { if (this.burnTime != 0 || this.furnaceItemStacks[1] != null && this.furnaceItemStacks[0] != null) { if (this.burnTime == 0 && this.canSmelt()) { this.currentItemBurnTime = this.burnTime = getItemBurnTime(this.furnaceItemStacks[1]); if (this.burnTime > 0) { flag1 = true; if (this.furnaceItemStacks[1] != null) { --this.furnaceItemStacks[1].stackSize; if (this.furnaceItemStacks[1].stackSize == 0) { this.furnaceItemStacks[1] = furnaceItemStacks[1].getItem().getContainerItem(furnaceItemStacks[1]); } } } } if (this.isBurning() && this.canSmelt()) { ++this.cookTime; if (this.cookTime == 200) { this.cookTime = 0; this.smeltItem(); flag1 = true; } } else { this.cookTime = 0; } } // this statement is causing the issue if (flag != this.burnTime > 0) { flag1 = true; MagFurnace.updateFurnaceBlockState(this.burnTime > 0, this.worldObj, this.xCoord, this.yCoord, this.zCoord); // report points to this line } } if (flag1) { this.markDirty(); } } updateFurnaceBlockState() method from my main block class: public static void updateFurnaceBlockState(boolean state, World worldObj, int xCoord, int yCoord, int zCoord) { int l = worldObj.getBlockMetadata(xCoord, yCoord, zCoord); TileEntity tileentity = worldObj.getTileEntity(xCoord, yCoord, zCoord); active = true; if (state) { worldObj.setBlock(xCoord, yCoord, zCoord, MagFurnaceActive.magFurnaceActive); // report points to this line } else { worldObj.setBlock(xCoord, yCoord, zCoord, MagFurnaceIdle.magFurnaceIdle); } active = false; worldObj.setBlockMetadataWithNotify(xCoord, yCoord, zCoord, l, 2); if (tileentity != null) { tileentity.validate(); worldObj.setTileEntity(xCoord, yCoord, zCoord, tileentity); } } any suggestions will be appreciated and I can supply any further information needed.

you need to create the slot in your GUI.png then add another drawTexturedModalRect(params of the slot) and replace isBurning with your custom method example: isConsumingFuel(). you'll need to create new methods for your power consumption. example snipplet (this is not the full method, just what you need to modify): if (this.magFurnace.isBurning()) { int i = this.magFurnace.getBurnTimeRemainingScaled(13); this.drawTexturedModalRect(k + 104, l + 33 + 12 - i, 176, 0, 14, i + 1); i = this.magFurnace.getCookProgressScaled(14); this.drawTexturedModalRect(k + 67, l + 33 + 12 - i, 176, 14, 14, i + 1); }
