Any reason why reflection doesn't work in the exported mod?

I've used reflection to gain a sort of "fast-place" hack, as you cant edit it manually as you would with a normal client. Anyway, whilst running the game through eclipse the mod works fine, fastplace works, but whenever I export it and try it in a normal minecraft instance it doesn't work at all... I don't have any idea why this would be the case...

 

try{

Field f = net.minecraft.client.Minecraft.class.getDeclaredField("rightClickDelayTimer");

f.setAccessible(true);

f.set(Minecraft.getMinecraft(), 1);

}catch(Exception e){

e.printStackTrace();

}

 

The mod works through the eclipse run button, but whenever I use the feature in a genuine minecraft window it doesn't work... Any help is greatly appreciated.

As I explain in this thread, vanilla fields and methods have multiple names. You need to check for both the SRG and MCP names when accessing a field/method through reflection.

 

ReflectionHelper.findField

and

ReflectionHelper.findMethod

make this easy by taking multiple names and trying each one until it finds the right one for the current environment.

Please don't PM me to ask for help. Asking your question in a public thread preserves it for people who are having the same problem in the future.

Ahh, that makes sense. Thank you.

 

Is there anywhere I can find the obfuscated/srg names for all the fields? Been searching for a while and can't find any documentation...

 

EDIT: Nevermind, I found the file C:\Users\{YOUR_USER}\.gradle\caches\minecraft\net\minecraftforge\forge\{VERSION}\srgs\mcp-srg.srg

Either look at the MCP mappings in the Gradle cache or use MCPBot.

I tend to grab the MCPBot exports that match the Forge version I have and keep them locally with my project.  Lets me reference them regularly very quickly.

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

 

Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

 

DO NOT PM ME WITH PROBLEMS. No help will be given.
