(Solved!) How should I make custom TNT?

[DanielD34]

I'm trying to make a really nice Minecraft 1.10 mod, and I'd like to give it some TNT, some that explode lava everywhere, and some that simply have bigger blast radii. How should I write the classes for the unprimed and primed versions of these? I already have basic coding knowledge and some textures.

 

Update: Thank you guys for making my modding easier! Sorry if some of my posts were rude before I fixed them; this was my first time on any forum.

Check out BlockTNT.java and go from there. For making the one that shoots lava everywhere, try having it spawn falling blocks with the block set to lava, and having those blocks spawn just before the explosion to have them actually go everywhere.

How do I do that? While I do have basic knowledge of Java, I'm still fairly new to modding and don't wanna mess anything up with the game's code. Also, I use Eclipse if this helps you find a good response.

You can't. Literally.

I think the book Minecraft Modding With Forge contains information about a custom TNT. I am not sure though. I know you need a TNT block class, a TileEntityTNT, a PrimedTNT entity, and something else I can't quite remember...

I don't feel like paying money for a book about modding, but thanks for the suggestion.

Thanks for the tip, but how do I get into that TNT class?

Thanks. I should've known.

Now, how do I get into that TNT class?

 

In Eclipse, under the Package Explorer, there should be a "folder" called Referenced Libraries (there might not be, in which case skip this).  Inside that will be a file called "forgeSrc-[mc version]-[forge version].jar"

 

You will be able to open up that jar file and brows the MC source code.  TNT will be down under:

- net.minecraft.blocks

- net.minecraft.entities

Thank you so much! That'll make modding SO much faster and easier!

I'll keep that in mind. You both have my thanks.

In a tool as versatile as Eclipse-J, there's more than one way to move around. In the future, if you can't remember where to look for something (or can't guess which package you need even after remembering the lib), then try throwing a spurious declaration into a method in any class you're editing. Write something like: BlockTNT tnt;

 

At that point, Eclipse will underline BlockTNT, and hovering will raise a complaint that it's unresolved. Right-clicking then should offer you the option of importing the class from Minecraft (NB: A handful of classes, like "Block", have very common names, so you may be offered imports from weird places that are almost always not what you want, and you won't have their source code anyway). Once you do that, then you can select it and hit F3 to open it in a new tab. Then delete your spurious declaration and type ctrl-shift-o to fix your imports.

 

Once you get into even one vanilla java file near what you want to use or imitate, then you can select things in it and use F3 to open more files. You may also ask eclipse to show any of those classes to you in the package explorer, which will expand whatever package you need wherever it is. In that package you may see other classes that could be instructive.

 

And then there's "show references", which can show you how something is used.

 

General take away lesson: An IDE is a powerful tool. Learn its features and use them.

 

PS: For vanilla source to show up, one must have setup a decomp workspace. The dev workspace doesn't include the vanilla source. It doesn't seem to be as much of a problem as it was a few years ago, but there may still be some necrotic "how-to" articles on the web telling noobs to setup the dev workspace.
