I've done the packet part now, but it still isn't updating the slots. I've committed and pushed my code on GitHub if you want to take a look at it.

I've putted the code into the detectAndSendChanges method. Here's the code: public void detectAndSendChanges() { super.detectAndSendChanges(); if(tileentity.upgradeScreenOpened && !this.upgradeScreen){ this.upgradeScreen = true; reloadSlots(); System.out.println("Sent"); } else if(!tileentity.upgradeScreenOpened && this.upgradeScreen){ this.upgradeScreen = false; reloadSlots(); System.out.println("Sent"); } System.out.println("Detected; "+ this.upgradeScreen + "; " + tileentity.upgradeScreenOpened); } But I found out that it doesn't detect when the tileentity.upgradeScreenOpened boolean changes. It always says in the console that it's "false". Am I doing something wrong?

I know that I'm not calling it. I tried some ways calling it, but most of them failed. I just don't know where and how to call it, so it works properly.

OK, I've done it. It's with ForgeGradle now. Just use the same link as before.

Oh, OK. I'll definitely install the ForgeGradle. I just didn't know that it was build .964. Thanks!

I don't think I can use ForgeGradle with 1.6.4. But I can give you the instructions: Assets are basically textures, so all you have to do is to copy the "cyborg53373_elementum" folder inside the "assets" folder into your "src/minecraft/assets" folder. The "elementum" folder is the code, you put that whole folder into "src/minecraft" folder. And that's pretty much it.

OK, I've putted it on GitHub, but I don't know if I did it right. Here's the link: https://github.com/Jeerdus/Elementum/

I did, but I couldn't find anything useful, think I'll try once more then.

I've never worked with GitHub. How does one set it properly up? Isn't there a tutorial or something?

I can't make it work! I tried 3 other ways and all they did was either the same as before, make them appear after you reopen the machine, or it didn't work at all!

I can't seem to be able to receive the packet. I am sending it, but it isn't receiving.

Where can I get or how can I create the onButtonClick method? Basically now I just need to call my other method which will move the slots.

Thanks for your help! I've just found that it isn't updating, I have to close and open the machine for it to update. Can I ask if there isn't a way for it to update?

Good day! I am working on a mod, which contains a machine in which there's a button which extends the GUI with few more slots. I made the GUI part, but now I'm struggling with the container slots. I don't know how to make them appear nor disappear. I got an idea that I could somehow move them from like x: -1000 and y: -1000 to the correct slot, but my code didn't work. (I used simple if statement) Could you please suggest me some ways of doing it? Thanks!

I don't quite understand the function. Could you please explain it to me?

How can I change icon of an item based on it's damage value?

Is there a way to "extend" tile entities that are already in the game? For example the anvil tile entity.

setNoRepair(); is for the 2 tools in crafting table repair. I've also tried getIsRepairable(ItemStack i1, ItemStack i2), but that doesn't seem to work.

Ok, thanks! I'll definitely try that!

Anyone?

Good day, I am working on a battery item for my mod and it uses data values for the amounts of energy it is currently holding, but the biggest problem comes when I put 2 batteries into the anvil. The damage value adds the second damage value and plus bit more. Example: If I put a battery with 1200 energy into the first slot and into the second slot the same battery with the same amount of energy, the outcome isn't 2400 as I would expect, but it is 3600. That means that it "generated" additional power. Is there a way to make it, so the outcome is 2400 or even better to completely disable the anvil recipe?

Good day, I made a block which connects to each other when they are next to each other. It isn't 1m3, but the standard block bounds are: (0.25F, 0.25F, 0.25F, 0.75F, 0.75F, 0.75F) Now when I place 2 of them, they connect nicely, but when I place 3 of them in a L shape. The middle one turns into: (0.25F, 0.25F, 0.25F, 1.0F, 1.0F, 0.75F) How would I make it look like pipes from BC or cables from IC. Does anyone know?

Fixed it! I don't need help anymore! But thanks for the help anyway.

Quick update: Somehow made it to work, now I'm trying to do, if the cell slot stack size is smaller then 2, don't do the recipe.
