I want to patch a minecraft class with the above code.

 

I searched how and I didn't find an answer.

 

...

when you say patch are you offering it as a patch to an allready availble mod or are you trying to patch a core file?

 

also :-

&& = AND

|| = OR

updated topic

Updated topic. AGAIN.

only way its editing that class, but i know some x ray mods that dosent edit bases classes, you must take a look at the way that you are doing your mod...

so no patching?

you can only patch java files, only way to edit a class file without decompiling it, its using reflection or asm but u can change what you want(you can onnly detecte obfuscation, change something to public, or to private, or to final, or to non final)

so you can't replace a method with another?

 

EDIT: Replaced "function" with "method"

is there a tutorial on it?

Using asm you can change ANYTHING in a class file at runtime (coremods) but is very hard to understand and use, as compiled java is very different to source java.

Here is the official tutorial for asm itself: http://download.forge.objectweb.org/asm/asm4-guide.pdf

As for setting up the mod side of it i do not understand, so I can't help you there

oh.

 

no tutorial on how to apply to mods.

Not that I know of, but NEI is open source so you could look at that if you want, you may be able to work it out from that

For now, that option is what I'm doing.

Actually, can i just do extends (classnamehere) then put the function that i want to replace?

Doing that will only change that method for anything that uses your new class, so possibly

oh.

 

wait...

 

I know, go submit a patch to the minecraftforge github?

Only if you think other modders could benefit from it

well, other people who are making x-ray mods are...

Well, i feel it's too much work... sigh..
