[1.10.2] Custom Machine Slots Going Crazy


Villfuk02
 Share

Recommended Posts

Can anyone help me? I'm trying to make it, when the progress is more than power_needed, it places output in the 5th slot and removes 1 item from the first 4. BUT it sometimes outputs, or removes the items too early, or even does output nothing/2 items at once/doubles the itemstack already there. WTF is going on???

 

I think it is something with the client not syncing with server ¯\_(ツ)_/¯

I think it is something with the client not syncing with server ¯\_(ツ)_/¯

 

This is possible from the behaviour you described. The client does not know what the server does. This is normal. The DetectAndSendChanges method in the Container should sync the values when the gui is opened. Maybe there is a bug somewhere. But it's a lot of code to look through, I could not see an obvious mistake in a quick look. You could try debugging with System.out.println, there you see what thread has written it to the console. If it's in a code that gets called on both sides you can see possible desyncs.

INTERESTING:

The items are doubling, because server thinks there arent items, so it in finishRecipe() sets both slot and the recipe as the same but for server the slot doesnt change but the recipe changes and its changed even between worlds, just until you close minecraft.

 

So i need to call server to update the slot after finishRecipe()

You should also stop using IInventory and use IItemHandler instead.

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

 

Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

 

DO NOT PM ME WITH PROBLEMS. No help will be given.

You should let run your item creating/removing code only on the server. (In tile entity update). On the client you should only change progress. If the server changes something with it's contents or state (finish/start), you need to send out a sync packet. This is done by marking the block for update. When getDescriptionPaket and onDataPaket is implemented in the tileEntity a sync with NBT tags is made.

I dont know how does IItemHandler work, can you please show me, what am i supposed to do with the boolean simulate, or the other things?

 

Read the javadoc

 

    /**

    * Inserts an ItemStack into the given slot and return the remainder.

    * The ItemStack should not be modified in this function!

    * Note: This behaviour is subtly different from IFluidHandlers.fill()

    *

    * @param slot    Slot to insert into.

    * @param stack    ItemStack to insert.

    * @param simulate If true, the insertion is only simulated

    * @return The remaining ItemStack that was not inserted (if the entire stack is accepted, then return null).

    *        May be the same as the input ItemStack if unchanged, otherwise a new ItemStack.
