Now I am quite experienced with modding.

How to register Data types made to simplify things in the Init method?

Init method of main class:

"... Do your mod setup. Build whatever data structures you care about. Register recipes.... " Quote from Bedrockminer's 1.7.10 modding tut code comments

I think he is referring to to either the proxy pattern or the static instances you initialize in the main mod file, both of which are basic code structures.

 

@Mod.Instance(Reference.MOD_ID)
public static ModClass instance;

@SidedProxy(clientSide = Reference.CLIENT_PROXY_CLASS, serverSide = Reference.SERVER_PROXY_CLASS)
public static IProxy proxy;

public static Random random = new Random();

@EventHandler
public void preInit(FMLPreInitializationEvent event)
{
    // Pre Init code here
} 

 

Pardon me for my unclear question.

See this page:

http://bedrockminer.jimdo.com/modding-tutorials/basic-modding/basic-modfile/

 

Then I saw "whatever data structures you care about"

Then I recall my custom-made LocationInfo type which looks like 1.8 BlockPos (and 1.7 dont have this)

Then I got a error log that I cannot interpret.

Then I thought is this related to something I did not do to tell Minecraft that there is a new type called LocationInfo?

Considering there is help here, I then decided to post here.

 

My conclusion is that something has to be done before Minecraft can understand my custom type.

No, you don't need to register your custom types.

 

I suggest these tutorials:

Hope someone can interpret this!

I am trying to make a global field, so that every code can access frequently used functions fast.

In case someone wants to have a look on the specified class:

package com.wwy.me3.Alpha;

 

import cpw.mods.fml.common.Mod.Instance;

import net.minecraft.client.Minecraft;

 

public class Globals {

@Instance

    public static Globals instance = new Globals();

public void printMessageToPlayer(String In){

Minecraft.getMinecraft().thePlayer.sendChatMessage(In);

return;

};

}

Try

 

@Instance("MyModName")

Hope someone can interpret this!

Ye gods man!  Where did @Instance come from?  It's used by forge to find a place to store your mod instance.  I really doubt you need it here!

 

-TGG

 

Oops.

Really. @Instance is not used except the main mod class.

Thanks!

Removed the "@Instance" you don't need it...

 

calling "Globals.instance" should allow you to get the static field from anywhere you want.

 

Reading the error, it's trying to set the Global instance to Main which is illegal... Removing the @Instance should make it work.
