I'm trying to make tnt not destroy anything that has water between it and the tnt, and...
I'm trying to make obsidian take 10 tnt hits before breaking.

Are these possible? Am I posting to many questions and ideas? lol

Ok what?

by **DeepGaze** » Sat Mar 29, 2014 17:51

can you provide a link to the mod(Tnt has been made by many modders)

replace the init.lua file with this(the init.lua is in the mods file) this replaces the water for a node called nomod:nonode witch AFAIK doesn't exist

by **mcfan** » Sat Mar 29, 2014 20:24

So is it replacing the default:water? What is it doing exactly?

by **DeepGaze** » Sat Mar 29, 2014 21:29

it is stopping the function by telling it to look for a false node(the code is pretty foreign to me)

Sorry to tell you this, but it didn't change anything. Destroyed stuff while in water and destroyed obsidian in one blast.

1. ask the mod creators
2. next time post these sort of things under mod requests
3. no hard feelings :)
4. HAVE FUN!

Why ask the mod creators? Why can't someone else take a stab at it if I can't get ahold of them?

post on the forum topic for best results: I was doing what I could without knowing the code (worst idea ever conceived, forgive me)

PilzAdam's TNT mod simply removes all non-liquid nodes inside a area: it does not check what is between that node and the TNT. Consider copying parts of my TNT mod, as it checks all the nodes in between

your mod would make a BIG mess of my place though because of all the tnt and their power. Does your tnt stop if there is water between it and a node?

by **mcfan** » Thu Apr 03, 2014 19:56

So was this a impossible idea?

by **LionsDen** » Fri Apr 04, 2014 01:10

I would say it's possible but difficult to implement. Not super difficult but a little bit.

by **minermoder27** » Wed Apr 09, 2014 01:04

I was not suggesting you copy all of it, just the ray casting bits.

you would need to change it to fit, and make it stop when it hits water
