原理

通过mixin注入Minecraft类中check禁止联机和聊天的方法，劫持并修改它的返回值。

代码（有动手能力的小伙伴可以自己逝逝）

@Mixin(value = Minecraft.class)

public class MixinBugJump {

@Inject(at = @At("HEAD"), method = "allowsMultiplayer", cancellable = true)

public void Fuck1(CallbackInfoReturnable<Boolean> callbackInfo){

callbackInfo.setReturnValue(true);

callbackInfo.cancel();

}

@Inject(at = @At("HEAD"), method = "allowsChat", cancellable = true)

public void Fuck2(CallbackInfoReturnable<Boolean> callbackInfo){

callbackInfo.setReturnValue(true);

callbackInfo.cancel();

}

}
