Solved Reflection Help

Hey. I am working with reflection here, but I am no so experienced in it. What should the objects in the set method be? I get this error:

Code:

02.03 11:18:59 [Server] WARN java.lang.IllegalArgumentException: Can not set java.lang.String field net.minecraft.server.v1_7_R4.MinecraftServer.motd to java.lang.String

Code:

Code:

    public void setMotd(String motd) {
        try {
            Class clazz = MinecraftServer.class;
            Field f = clazz.getDeclaredField("motd");
            f.setAccessible(true);
            f.set(motd, "motd");
        } catch (Exception ex) {
            ex.printStackTrace();
        }
    }

 

@WesJD

You have to pass in the instance an instance of MinecraftServer in f.set();.
So in your case:

Code:

Class<?> serverClass = MinecraftServer.class;
Field theField = serverClass.getDeclaredField("motd");
theField.setAccessible(true);
theField.set(MinecraftServer.getServer(), <motd>);

 

@CaptainBern Thanks!
