[1.7.2] TNT, setResistance, and createExplosion help

[Parker8283]

I'm currently on working on adding a custom bomb to my game. However, it helps to understand what's going on with TNT in the game. I have a pretty long question (Also, correct my if I'm wrong on any information here) Whenever I've added a block, I add ".setResistance(float)" to the declaration. I usually use the Block.class file in Minecraft as reference. When I look at the declaration of the .setResistance function, it takes the float passed in, multiplies it by 3 (or 3.0F), then stores it in the protected variable "blockResistance". When I check the EntityTNTPrimed.class, in the explode function, it creates an explosion with a strength of 4 (or 4.0F). However, when placed next to a piece of End Stone (resistance 15.0F), it explodes. I went through BlockTNT, EntityTNTPrimed, and World, and then Explosion classes (the last one gave me a headache), and have seriously no idea what is going on. Could someone fill me in on what's going on, and how this all works with setResistance and how TNT can blow up something of a resistance higher than it's strength?

The float in TNT is not how strong the TNT is, its however how big the explosion is...

 

I suppose you are looking how to change it, well its in Explosion.class.

I'm not looking how to change it; I'm looking how to understand it as I make a custom bomb for my mod. And I still don't understand. What is setResistance setting, and what float makes it not possible to be broken with one piece of TNT?

[coolboy4531]

Hmm. Let's see here. Okay... got it.

 

1) setResistance = Resistance, it saves as a data value, and when it reaches 0, it gets destroyed.

2) Haven't looked into detail, somewhere in Explosion. If you can override that, or create your new handler for explosions you can change the value.

[Parker8283]

Alright, so how does the strength float that is passed in under createExplosion in World.class tie into the resistance float? Where do those two floats meet to decide whether or not the block gets exploded?

[coolboy4531]

I haven't explored that far, nor have I ever meant to study on Explosions.

 

Try and look around, test some stuff, solving your own problems will make you more advanced into these things.

 

Good luck, I'll try to help around, too
