It is kinda hard to charge anything or get if it is chargeable at all if it happens to be null for instance

Here's an example for you: this.worldObj.setBlock(this.xCoord, this.yCoord, this.zCoord, Blocks.stone) That turns your block into stone.

The feature has not been implemented yet as they have still some kinks to work out. I figure it will be up in no time.

Hello there. For my mod I need some kind of way to transfer fluids and for that I have made pipes. I also wanted to see if there is any fluid in there and with a glance also what is in there. So I created myself TESR to render the fluid "block" inside my pipe block. However, as you might see from this picture, it didn't go that well. So I'm asking you people here to give me some pointers how I can make this rendering work. Here is the TESR code. Thanks in advance for anyone who is willing to take a glance of this code and maybe even give me some pointers on how to fix this.

Maybe, just maybe if you showed me the code I could help you. And you should really make yourself github repo so it would make it easy to show other people.

if (world.isRemote) Hmm, all I could guess is that entities should be spawned server side as it should keep clients aware of it being there after it is created. Try if(!world.isRemote) instead

Where do I put the Use ItemSword#onItemRightClick? My code for the shooting part is here. First off, Use is not command. Second off he means that you should override onItemRightClick on your Sword class.

Does the arrow still go toward the target it is homing? If so then via basic trigonometry you can figure the pitch and yaw out. Sorry, I cant exactly post and example code as I am going to class but that is the basic thing to do.

I assume that because both classes implement ITileentityProvider, he wants to have the now late lock A's tileentity with Block B's tileentity.

Enginecrafter, the advantages of having your project in Git is that for instance you can develop your mod from everywhere where there is IDE and if your hard disk fails you will have not lost your project. I myself would be lost nowadays without Github repo.

That's not what modding is about. We can guide you but you do all the stuff by yourself.

Maybe if you told us what the error said we could help. I personally don't have a crystal ball so I can't see it unless you give us the error message.

Could someone give me a quick crash course on how to make the JSONs to work. Where to place the textures ect. What about switching states such as having a model that changes one texture depending if the block is on or off. Ktnxbye.

The answer does not require the use of an API. Anyway if you want to have compatibiliy between your and some other guy's mod you must use API that you clarity in mcmod.info file.

You should use constructor to get your tileentity because at the moment your code generates new tileentity everytime it runs. So yeah, make constructor.

Show the code please as our crystal balls are kinda not working.

Send me like a pastebin of your code or something in PM and I can help you.

I think I understand what you want to be able to do. And I will give you the idea how to do it but you have to implement it. First step: create tileentity classes for your cooleant generator and your server and register it. I will assume that you dont want to make the cooleant an item because that is tiny bit more complex. Second step: create a variable called cooleantAmount on both server tileentiy and generator tileentity and create methods getCooleantAmount to both and into the server tileentity you create method addCooleant. Step three: on your generator tileentity's onUpdate method you want to increase the value of cooleantAmount by how much you want be generated. You also wanna check if any blocks around the generator have tileentities mathching the server tileentity and if it is call that particular server-tileentity's addCooleant-method and remove that amount from the generator's cooleantAmount Step 4: Check in your server tileentity's onUpdate-method if you have enough cooleant and do it do what it should. It wasnt so hard was it.

Please show us the source file where you register the entity (entities as the error message says that you are registering two different things under the same ID).

Please give us the actual error message maybe we could help. ATM we dont know shit about your problem. Also attach the whole code where the error message is refering to.

I don't know if I get this straight, you mean I can just put "C:\Users\User\Desktop" as a domain? Or I have to "create" a domain? Explain that part a little bit please He said that you have to implement IResourceLocation. Im not at my computer so I cant give you any further instructions but try to see what you need to implement.

Do you want the smelting in a furnace or something? If so, you must understand how blocks in inventories are handeled. Blocks in your inventory are actually not extends of the class Block. Instead they inherete the class called ItemBlock that represent blocks on your inventory. ItemBlock extends the Item class. I think you can now figure out how to do this.

Yeah, I added a null-check and now it works fine. Sorta dumb of me because I should have known that would be needed. It may have been a brainfart. Thank you anyway.

So yeah, the problem is in the title. And the funny thing about it is that it only happens on block that has been already placed after world reload.
