That means that you are messing with administrator things, and that being the case, I can't help you.

Ok, remove IntelliJ IDEA from the folder and place it somewhere else. Delete all forge stuff from there, redownload forge from the website, extract it into the folder, delete the src folder, and all the .txt files in there. Then, shift+rightclick inside the windows explorer folder, and click the open command window here. Type gradlew setupDecompWorkspace and tell me what happens. I'm going to assume you're using IDEA, so if it works type gradlew idea.

Have you changed anything administrator-related about the folder? If so, this is your problem. Does it say anything about --stacktrace or something like that?

If ALL your command prompt says is Access Denied, I think you have a bigger problem.

Again, I need a screenshot. I'm not going to be replying until you post one because it's apparently completely futile.

That's ALL it says in your command prompt? I would say that you, sir, have a broken computer/command prompt.

That's exactly what I'm saying. You can miss something by being too egotistical to even consider the possibility that you may have missed something and that maybe providing a screenshot could help you out. Forget it, I can't and I won't help you until you let me help you.

How many times do I have to explain to you? Because then I can see something you may have missed, and I can provide you with better help.

If I may ask, why are you so adverse to providing a screenshot of the command prompt window? Just take a screenshot of it, and provide it.

It's going to help because I can see everything in the command prompt, not just what you are telling me. If you are so adverse to providing a screenshot of the command prompt, copy what is in there down to the letter, however I believe it would be easier simply to use the screenshot tool Windows provides you to take a screenshot of the command prompt and post it on here.

Where is your summoner variable?

I can't help you without a screenshot, or an error log, or whatever. Maybe you did some weird administrator thingies? I can't help you without a screenshot, having never encountered this problem myself.

I'm going to say it again. Provide a screenshot. I can't help you otherwise. Also, who's tutorial are you following? If it is anyone's but ScratchForFun's, Pahimar's, Wuppy's, or Vswe's, I would heartily suggest you switch over to their's. Also, the fact that the tutorial says nothing about it means nothing except that the maker forgot to put in the video.

Ok, I'm going to need your recipes class, because the method is obviously in there.

Provide screenshots, pastebin, or something. You also have to set a JAVA_HOME variable, have you done that?

Well, I can't really help if you don't provide source, but I'd wager you are trying to pass an ItemStack on that method instead of a String, which is what it says in the error. This is a basic java error, please try fixing it yourself before coming to this forums, as this is a Forge forums.

First of all, I'd suggest using the Tessellator to render, because it provides more customisability, but that is up to you. Second, you can from the get-go bind two textures and then, in your render code, just don't use the texture. You can then make a boolean that will be true if the tank is active and if the boolean is true, draw render code that uses that texture. If you are using Techne, I can't really help you, so I'd suggest using the Tessellator.

Nah, I just want a normal hollow 5 x 5 x 5. I do want the activation to be based on a right-click, and I do want different blocks in the multiblock to have different metadata. Again, don't provide me with copy/paste, just basic instruction.

However, could you elaborate a bit? Not copy/paste code, but a bit more in depth? Cause I was having a little trouble fully understanding.

Yup, it certainly does. Thanks!

I got that same error when I had an exclamation point in the folder name. If you want to get rid of the error, delete any exclamation points from your folder name and try again. This should clear up any problems.

Hello, does anyone have any ideas on how I could make a hollow multiblock structure? Meaning that it would have walls on all sides, but no blocks in the middle. Thanks in advance!

Could work.

Thank you. I heard that the Chestplate was 3, but that didn't make sense so I decided to ask.

As far as I could see, you only had things such as Xcoord + x, no Xcoord - x anywhere. I think this may be your problem, but if it is not, then I am completely out of suggestions.
