(jitpack build does NOT contain the examples and the plugin.yml, don't worry)

made for fun

grabbed main classes from Revxrsal/EventBus (GeneratedClassDefiner, GeneratorAdapter, Method)

spaghetti code, i know.

accessing entity player example:

CraftPlayer.java

import me.acablade.nmsasm.NMS;

@NMS
public interface CraftPlayer {
	
	@NMS("getHandle")
	public Object getHandle();
	
	@NMS("sendMessage")
	public void sendMessage(String message);

}

And then you use it as:

CraftPlayer craftPlayer = NMSAsm.get(CraftPlayer.class, player);
Object entityPlayer = craftPlayer.getHandle();
craftPlayer.sendMessage("Hi there!!");

Dont forget to register the classes such as

NMSAsm.registerNMSClass(CraftPlayer.class);

in onEnable.
