I need help, I want to change what iron and gold drops, but i dunno the event that is doing it so I can't hook it. The only way i managed to do it is editing the BlockOre vanilla class, but this may cause mod incompatibility. I also want to remove some vanilla recipes without editing vanilla classes or is it uneccesery?

 

NOTE: I started modding forge 2 days ago, without knowing the java or any other language.

ASM or Reflections.

As I said i started proggraming 2 days ago. What is ASM/reflections?

I'll tell you what I did to change the loot from killing a sheep, I think it is similar to changing the drops of a iron ore block.

 

I removed the spawning of sheep in my main mod file.

I added my the spawning of a sheep(my mod sheep).

Then I created the class of 'my mod sheep' and extended the vanilla Minecraft Sheep class.

 

I used a @Override command to override the code that defined the drops when sheep gets killed.

DemoXin just published his "FortuneOres" mod which does exactly that and is open source, so you can check for yourself how he did that - or ask him:

By using a coremod: http://www.minecraftforum.net/topic/1854988-tutorial-162-changing-vanilla-without-editing-base-classes-coremods-and-events-very-advanced/

or

or By using reflexion: http://tutorials.jenkov.com/java-reflection/index.html

 

Coremod is the way to do because it's Forge based. But reflexion works too.

Omg, he was 1 day ahead, just about to make the same thing... Anyways thanks guys, good thing my mod has something more...
