hi,

 

im trying to make a mod, i used to be able to just edit the classes but now we cant edit the classes in the new forge gradle. i want to know how to replace a mc class with my own class and if we cant do that i want to know how to override a method in a different class?

 

i either have to override a whole bunch of methods or edit the class and replace the original with my own

 

 

here is how i was trying to override methods

 

 

package com.example.examplemod;

(all imports that i need)

@Mod(modid = ExampleMod.MODID, version = ExampleMod.VERSION)

@SideOnly(Side.CLIENT)
public class ExampleMod extends RendererLivingEntity
{


 public static final String MODID = "examplemod";
 public static final String VERSION = "1.0";

public ExampleMod(ModelBase p_i1261_1_, float p_i1261_2_) 
        {
	super(p_i1261_1_, p_i1261_2_);
	// TODO Auto-generated constructor stub
}

    @Override
    protected void renderModel(EntityLivingBase p_77036_1_, float p_77036_2_, float p_77036_3_, float p_77036_4_, float p_77036_5_, float p_77036_6_, float p_77036_7_)
    {
       ...
    }


        // eclipse tells me to add this unimplemented method
@Override
protected ResourceLocation getEntityTexture(Entity p_110775_1_) {
	// TODO Auto-generated method stub
	return null;
}
    
}

 

my question is: how do i go about replaceing a whole class with my own or how to override a method that is in a mc class?

 

 

when i run eclipse MC doesnt run, i get this VVV

Don't replace vanilla classes. It seems you are looking for the RenderLivingEvent.

 

i have to use event handler right? you know any good tutorials? and do i use it to call my class instead?

My tutorial on events might help: http://jabelarminecraft.blogspot.com/p/minecraft-forge-172-event-handling.html

 

Basic idea is that you need a handler class that "subscribes" to the event, and you need to register that class as a handler.

 

When the event occurs, you can use the data passed in the event parameter to further determine what happened then do whatever you want.  Depending on the event, many are cancelable, meaning you can totally override what the vanilla code does.

Check out my tutorials here: http://jabelarminecraft.blogspot.com/

ok so i read up on event handling and (from what i read) i cant edit or override (am i missing somthing?) the "func_96449_a" method in the "RendererLivingEntity" class

 

 

for example if i edit "func_96449_a" i can make the player nametag green instead of white. in mcp 903 (mc version 1.7.2) i edit the class and was able to run and everything (within eclipse), but it wasnt recompiling or reobfuscating. now i am using forge and want to edit or override that method (preferably from my mod class, i kind of dont want it to be a "coremod"), how do i do that?

To make a Player nametag green use PlayerEvent.NameFormat and apply the color modifier there.

 

OMG THANKS :D

 

sorry for too many questions, but do u happen to know any event that i can use to change background color?

For further modification you need to render the player yourself, by canceling the RenderPlayerEvent. But that may cause some incompatibilities.

 

ok, so to cancel is 

event.RenderPlayerEvent(true);

. but then how would i render the player?:-[

There are some times when you really need to do a base edit (replace and or modify a minecraft class).

Most of the time you can use events and other cool forge stuff...

 

If really need to edit something what you need to do is make a coremod.

I found is one good tutorial out there...

http://www.minecraftforum.net/forums/mapping-and-modding/mapping-and-modding-tutorials/1571568-tutorial-1-6-2-changing-vanilla-without-editing

 

It is for 1.6.2, but there is still some good info in it!

 

One thing that I thing really helps it to have the forgeSrc not the forgeBin in the classpath thingy in eclipse (or what ever IDE you are using).

You can do this by running...

linux:

./gradlew setupDecompWorkspace

and then ./gradlew eclipse (to update the classpath)

windows:

gradlew setupDecompWorkspace

and then gradlew eclipse

 

and one more note! look at the code that forge uses to load coremods/mods (mostly the coremods part)

      OpenAL.dll issue (causing crash)

      By bkbenji · Posted

      Is there a fix for this issue? I have tried reinstalling OpenAL.dll, switching Java versions, and even muting my game when it launched, but all of these attempts have resulted in my game crashing nonetheless. I have been dealing with this issue for approximately a week straight. I have not changed any sound settings, so I am very confused. Full Code: https://gnomebot.dev/paste/mclogs/beEBzpm "4/16/2025 12:16:30 AM 1000 Error Faulting application name: javaw.exe, version: **.**.**.**, time stamp: 23 0xd75c3041 24 Faulting module name: OpenAL.dll, version: **.**.**.**, time stamp: 0x647635a125 Exception code: 0xc0000409 26 Fault offset: 0x00000000000a2b05 27 Faulting process id: 0x10A0 28 Faulting application start time: 0x1DBAE81D04A6F2F 29 Faulting application path: C:\Users\********\curseforge\minecraft\Install\java30 \java-runtime-delta\bin\javaw.exe 31 Faulting module path: C:\Users\********\curseforge\minecraft\Install\natives\n32 eoforge-21.1.148\OpenAL.dll 33 Report Id: 28552180-f359-40cc-adeb-08dada7e99d8 34 Faulting package full name: 35 Faulting package-relative application ID:" Any sort of insight would be greatly appreciated, it's giving me a headache.

      I can't get this modpack running.

      By Calcifer · Posted

      I'm new to this, if that wasn't obvious. My friend and I are trying to make a modpack for 1.19.2. I've made a modpack previously with 0 issues before and many of the same mods. However, I can't seem to find the issue when trying to load up his new modpack.   Any help would be greatly appreciated.

      Okay, for him the config file looked like this: flywheel-client.toml: #Select the backend to use. Set to "DEFAULT" to let Flywheel decide. backend = "DEFAULT" #Enable or disable instance update limiting with distance. limitUpdates = true #The number of worker threads to use. Set to -1 to let Flywheel decide. Set to 0 to disable parallelism. Requires a game restart to take effect. #Range: -1 ~ 12 workerThreads = -1 #Config options for Flywheel's built-in backends. [flw_backends]     #How smooth Flywheel's shader-based lighting should be. May have a large performance impact.     #Allowed Values: FLAT, TRI_LINEAR, SMOOTH, SMOOTH_INNER_FACE_CORRECTED     lightSmoothness = "SMOOTH" There was no "INSTANCING", so we changed "DEFAULT" to "OFF", but this didn't help. Changing it to "INSTANCING" didn't work as well.
