Hello everyone,

I am brand new to using Java and I am trying to learn Java from learning how to create mods with it.  When I tried to run the game with my mod I got a message that said "Java HotSpot(TM) 64-Bit Server VM warning: Using incremental CMS is deprecated and will likely be removed in a future release" 

 

(guns is a placeholder name.  I am not sure if that's what the mod will be yet I just want to get it running)

This is what the report of the crash says:

If there is any other information that you need in order to help me let me know.  I have never done this before so as many details as possible would be greatly appreciated!

Attempted to load a proxy type com.o_so_hexxy.guns.proxy.ClientProxy into com.o_so_hexxy.guns.guns.proxy, but the types don't match

 

Show your main mod class.

package com.o_so_hexxy.guns;

import com.o_so_hexxy.guns.proxy.CommonProxy;

import net.minecraftforge.fml.common.Mod;
import net.minecraftforge.fml.common.Mod.EventHandler;
import net.minecraftforge.fml.common.Mod.Instance;
import net.minecraftforge.fml.common.SidedProxy;
import net.minecraftforge.fml.common.event.FMLInitializationEvent;
import net.minecraftforge.fml.common.event.FMLPostInitializationEvent;
import net.minecraftforge.fml.common.event.FMLPreInitializationEvent;

@Mod(modid = Reference.MOD_ID, name = Reference.NAME, version = Reference.VERSION, acceptedMinecraftVersions = Reference.ACCEPTED_VERSIONS)
public class guns {

    @Instance
    public static guns instance;
    
    @SidedProxy(clientSide = Reference.CLIENT_PROXY_CLASS, serverSide = Reference.SERVER_PROXY_CLASS)
    public static CommonProxy proxy;
    
    @EventHandler
    public void preInit(FMLPreInitializationEvent event)
    {
        
    }
    
    @EventHandler
    public void Init(FMLInitializationEvent event)
    {
        
    }
    
    @EventHandler
    public void PostInit(FMLPostInitializationEvent event)
    {
        
    }
}

 

Fucking hell, I hate some of the tutorials out there.

I also need your Reference class, and while you're at it, the common and client proxy classes.

You have 10k posts so obviously you must have plenty of experience.  If there are any specific tutorials or guides that you think are really good let me know and ill be sure to take a look at them.  I don't want to learn how to do this badly. 

 

REFERENCE CLASS:

=======================================

package com.o_so_hexxy.guns;

public class Reference {
    public static final String MOD_ID = "ogm";
    public static final String NAME = "GunMod";
    public static final String VERSION = "0.1";
    public static final String ACCEPTED_VERSIONS = "1.11.2";
    
    public static final String CLIENT_PROXY_CLASS = "com.o_so_hexxy.guns.proxy.ClientProxy";
    public static final String SERVER_PROXY_CLASS = "com.o_so_hexxy.guns.proxy.ServerProxy";
}

=======================================

 

 

COMMON PROXY CLASS:

=======================================

package com.o_so_hexxy.guns.proxy;

public interface CommonProxy {

}

=======================================

 

 

 

CLIENT PROXY CLASS:

=======================================

package com.o_so_hexxy.guns.proxy;

public class ClientProxy {

}

=======================================

 

 

Thank you for your help!

Your client proxy class and your common proxy interface aren't...related to each other.

 

If I did this:

interface Cat {
}

class Banana {
}

It would be the same: you can't assign an object of type Banana to a field of type Cat

public class ClientProxy {

Your ClientProxy class is not related to anything. This suggests that you're not just new to Java, but you're new to object-oriented programming. First, you need to go find tutorials on O-O programming and Java before this forum can help you. Second, you need to build a cache of bookmarks to useful Java references / forums. Learn to go to those for fundamental Java questions before coming here with more advanced questions peculiar to Forge hooks, mod structure etc.

 

PS: Another good way to learn is to explore the Minecraft source code itself. When planning a mod, try to see how vanilla Minecraft does things before asking. And if you don't know how to use Eclipse to do that, then there is an Eclipse site out there to help you learn that tool of the trade.

Oso,

 

I agree that you will need some basic java in order to move forward. Too many other issues with coding the forge mods if you don't have a basic understanding of java.  However, if you know how to use github, there are a lot of good examples, tutorials to help you get started.  The proxy issue is there because there are things you want to execute on the server only, client only, or both and setting up the common/client proxy allows you do this easier. This is done by the client proxy extending the common one.

 

Check out.... lots of starting examples where you can clone the repository, get it to compile/run, then start tweaking.  When the examples are too large to start with, it can be difficult to follow everything, greyghost has some nice simple ones to help get you started.

Good luck,

 

p.s. vanilla code is very helpful when trying to figure out stuff. Assuming you've done the gradlew setupDecompWorkspace and eclipse (see readme file from forge download)...should be under you project reference libraries under the forge version.
