[1.8.9] Replace Vanilla Classes

[Helliot]

Hi!

 

I'm actually trying to replace some Minecraft Vanilla Classes, like AbstractClientPlayer or WorldClient (And a lot of other classes)

 

I've already tried to make a custom client with MCP, and it works without Forge. But Forge won't load it, and i don't have any stacktrace.

 

My goals are:

 

*Changing the skins loading (I want some HDSkins by my own skin database)

*Changing vanilla mechanics (Like the day/night cycle duration for example)

*Changing some GUI (I know that there is a way to do that without changing the classes, but if i can do that by changing the classes it's better for me)

*Adding a picture on the player's head when he is writing (I have to change a lot of classes for that, and adding some Packets)

 

Thanks for helping me out <3

Most of that can be done with events, no need for changing vanilla classes.

For everything else you can use ASM, but I don't recommend it

Thanks for the reply! I will have a look on it!

No no NO NO NO!

Class changes should be last thing you try and only if it is the only one left, because they can make a lot of things incompatible and broken.
