Coremod?

[F0X]

So I wanted to create my own mod, that makes some modifications wiht rendering and stuff, for example I need to edit the EntityRenderer class.

 

I read about coremods and started developing my own, but then I saw many posts on this forum saying coremods are highly deprecated and shouldn't be used.

Now my question is how to achieve my goal of building my own client modification, and how do mods like labymod or oldanimationsmod work, that definetely change the client code?

 

I know i could for example just set

Minecraft#entityRenderer

to my own custom EntityRenderer, but is this a better way of dealing with the problem?

Yes, coremodding requires extreme knowledge of byte code manipulation and is very incompatible with mods.

Not if done very well, but that requires even more extensive knowledge, time and effort.

It depends what exactly you are trying to achieve and if other mods modify the same class/method. This is the more accepted (and much, much, MUCH easier) way of doing it.

 

Coremods require learning an entirely new language (Java Bytecode) and learning how to use the ASM library, which is almost as hard as learning another new language. Java Bytecode is a low-level language and doesn’t have any of the structures your used to from other languages (as bytes it resembles Machine Code and as instructions it resembles Assembly)

 

Coremods also break completely with the slightest change to the original code you’re modifying (if another variable is added anywhere in the method for example)

Cancel the entity's render even and render your own.

Draco18s has a very good point. Why do you need to edit the EntityRenderer class? Are you sure you can’t use forge’s event system?

Thats not the hugest problem to me, because I wanted to learn about bytecode-manipulation anyways, but it would really take a while 'til I am able to create a "good" coremod, true.

I this particular case of course, but the thing is, I'm trying to create an "own client like" mod, that changes many behaviors of the normal client.

Before I did this kind of thing with MCP directly, but this time I want a mod, because I want it to be compatible with other mods I use.

 

This is one of my first mods with forge, so I am not really familiar with the whole Forge API, but I'm definetely going to try using the event system and for now probably not a coremod.

How do I do this? Sry to ask, but the docs are really short and there is no javadoc online.

In your event subscriber add a @SubscribeEvent to the RenderPlayer.Pre event, cancel it and do your rendering

Thanks, I hate it when there's literally no documentation on things.

I know, but it doesn't tell you all the events and stuff, its just a brief introduction imo

Use your IDE to look at all the classes that extend Event
