Hello,

I'm having an issue with getting players to use elytra flight. They do not have any elytra armour on their chest plate but rather the elytra is rendered on the player.

What I've got so far seems to make the server 'fight' with itself making the person with the elytra begin flying but immediately go back to non-flight. 

I'm checking if the player is off the ground and such client and server side using packets.

Client code:

        @SubscribeEvent(priority = EventPriority.HIGHEST)
        public static void onKeyInput(InputEvent.Key event) {
            if (Minecraft.getInstance().options.keyJump.consumeClick()) {
                Player player = Minecraft.getInstance().player;

                if (!player.isOnGround() && !player.isFallFlying() && !player.isInWater() && !player.hasEffect(MobEffects.LEVITATION)) {
                    NetworkManager.sendToServer(new ElytraAttemptFlyPacket());
                }
            }
        }
    }

Server code:

public class ElytraAttemptFlyPacket {

    public ElytraAttemptFlyPacket(FriendlyByteBuf buf) {
    }

    public ElytraAttemptFlyPacket() {
    }

    public void toBytes(FriendlyByteBuf buf) {
    }

    public boolean handle(Supplier<NetworkEvent.Context> supplier) {
        NetworkEvent.Context context = supplier.get();
        context.enqueueWork(() -> {
            //Server
            ServerPlayer player = context.getSender();

            if (!player.isOnGround() && !player.isFallFlying() && !player.isInWater() && !player.hasEffect(MobEffects.LEVITATION)) {
                player.startFallFlying();
            }
        });
        return true;
    }
}

As I said before it kind of works but it looks like the server is fighting with itself putting the player in elytra mode and normal mode.

Any suggestions would be appreciated!!

Issue was solved using the Caelus API.

There was a PR on adding a custom elytra item. Unless you're doing this without any items whatsoever, I would suggest using the system Forge already has hooked for you.

I am using the Caelus API to handle my elytra flight, so far it seems to have solved my issue. Thank you for your help though!!
