I'm in the middle of a big modding project, and my chemical extractor is having some weird issues.

There is no actual 'error' in the code, however it still doesnt work correctly.

 

Symptoms:

I put any item in the slot and it doubles

Left click to remove and the item disappears

right click divides stack in slot by 4 and the rest disappears

does not process the item at all.

 

I based the code of the vanilla furnace, but changed it to use an electrical supply which I am yet to implement. To 'charge' the block I change the value in the eclipse editor, but it still doesnt function.

Any help would be appreciated.

I had this thing some time ago. It's likely because of getting wrong side TileEntity. You have to show your IGuiHandler.

I don't have that much time to go through whole code: Container is good that I can tell, as to TileEntity - at some point you are PROBABLY making ghost items - that means they have different properties (stacksize etc.) that are actually showed. Hint for you: Add println before and after getting ANY itemstacks - like:

ItemStack is1 = ExtractorRecipes.extracting()
.getFirstExtractResult(this.extractorItemStacks[0]);
ItemStack is2 = ExtractorRecipes.extracting()
.getSecondExtractResult(this.extractorItemStacks[0]);

or

extractorItemStacks[2].stackSize += is2.stackSize;

Also check if you are not stacking over Stacklimits (saw you did it in canExtract - but just make sure)

This post won't help you much but I can assure you that println will

 

Also (as a guy before me said) - GuiHandler should look like this, so make sure it does:

public class GuiHandler implements IGuiHandler
{
@Override
public Object getServerGuiElement(int id, EntityPlayer player, World world, int x, int y, int z)
{
	TileEntity TE = world.getBlockTileEntity(x, y, z);
	switch(id)
	{
		case 1: return new MyContainer(player.inventory, (MyTileEntity) TE);
	}
	return null;
}

@Override
public Object getClientGuiElement(int id, EntityPlayer player, World world, int x, int y, int z)
{
	TileEntity TE = world.getBlockTileEntity(x, y, z);
	switch(id)
	{
		case 1: return new MyGui(player.inventory, (MyTileEntity) TE);
	}
	return null;
}
}

I have changed the GUI handler code and it works now. however, when I place an item into the input slot, the getPowerRequirement function in the recipes class (attached below) crashes with a null pointer exception on line 81. I tried adding a try-finally statement, but that didn't help at all. any suggestions?

,,This post won't help you much but I can assure you that println will "

Probably when some method from TileEntity is calling for result (res) it gets wrong shit

Place println before/after every calling of getPowerRequirement and also inside it when there is try/finally part.

I can't help much when I don't see whole code
