Well, you registered a new keybinding. Did you create a static reference to hold it? Did you do anything to make sure that reference had a value?

I had this before in the mod class...

but diesieben07 told me that KeyBinding was a Client-Only class so I removed it.

You cannot put it in your mod class, because your mod class is loaded on client and server. You must put it in a client-only class (or rather: By putting this in a class, that class by proxy becomes client-only as well. If you put it in your main mod class, your main mod class becomes client only, which makes your whole mod client-only).

I believe I have to put some sort of annotation on top of the class/variable to specify its only a client class/variable. 

But from what I read from the Javadoc, this wouldn't work with initializers I think, right?

What do I have to put to specify that this class/variable only runs in client, if this isn't it?

 

Or no annotation at all, like you said here?

Do not use @OnlyIn.

 

To access client-only classes (such as KeyBinding or your now created InitKeys class, which is client-only because it has a reference to KeyBinding in it) either use @EventBusSubscriber with a Dist.CLIENT parameter or use DistExecutor (somewhat awkward to use correctly).

Previously I was calling the key variable from 2 places:

 

1.A client event from the client-side only event-handler like you said now.

I guess I'll have to make that reload method (2.) an event in the same event-handler as (1.), right?

Reloading is a server-side operation... so you need to send packets informing the server that you want to reload.

After reading a few posts and wikis etc etc, I started with the packet thing, but when I tried to make the Message class, it appears I cant implement from IMessage. Is this a bug? or does this interface doesnt exist anymore?

It doesn't exist anymore, you have to make the methods manually, it looks a bit like this:

public class MyMessage {
  int value;
  
  public MyMessage(int value) {
    this.value = value;
  }
  
  public static void encode(MyMessage msg, PacketBuffer buffer) {
    buffer.writeInt(msg.value);
  }
  
  public static MyMessage decode(PacketBuffer buffer) {
    return new MyMessage(buffer.readInt()); //Remember to read in the same oreder you wrote!
  }
  
  public static void handle(MyMessage msg, Supplier<NetworkEvent.Context> ctx) {
    if (ctx.get().getDirection() == NetworkDirection.PLAY_TO_SERVER) { //Checks if the packet's direction is to the server
      ctx.get().enqueueWork(() -> {
        //Your code goes here
      });
    }
    ctx.get().setPacketHandled(true);
  }
}

I'm 99% sure that's correct, kinda freestyled it though. To send it use SimpleChannel#sendToServer, don't forget to register it with SimpleChannel#registerMessage, and don't worry if you don't understand it right away, it took me a while to fully understand packets in 1.15.

This is my first time with packets anyway XD, I'll give it a try this afternoon.

Yeah, I'm aware of this, I just needed the message class.

Ok so I've now finished the packet implementation, its working as expected but I wanted to know your thoughts to know if its fine.

That's fine, all I would change is use ClientTickEvent instead of InputEvent.

Does that run in every tick? if it does, wouldn't that be more spammy than the InputEvent that runs when the player presses any controls?

 

I could be wrong, it's the first time I heard of ClientTickEvent XD

I have no idea why it's better, but I've seen people recommend it a lot on these forums, maybe someone else could clarify why.

Input event only gets called once when pressed, which if you use TickEvent you can check if the mouse is down manually, and allows you to “fire while having the mouse pressed” instead of constantly clicking the mouse to fire
