So I followed Modding by Kaupenjoe's tutorial on  keybinds for 1.19, and that's all working fine, however I want to make it a mechanic, in which you press the button, it fires a magic projectile and applies and effect to the target, and has a cooldown before being able to use again. However there's no clear "Fire Projectile" with my current code. I assume I'd need to create my own custom projectile class, with visual effects, but how could I implement it into the keybind? All I'm trying to do as of yet is get it to fire an arrow where I'm looking and without an item and include a cooldown, Any advice is greatly appreciated ^ v ^

 

This is the current keybind Code:

 

public static class ClientForgeEvents {

@SubscribeEvent public static void onKeyInput(InputEvent.Key event) {

        if(Keybindings.Cast_Magic.consumeClick()) {

               Minecraft.getInstance().player.getDirection().getOpposite();

                   }

           }

}

You should check here KeyMapping#isDown

This depends on what projectile you want to shoot, if you want a custom projectile yes, if you want to shoot a Arrow or a Fireball then is is not necessary.

In all cases you need a custom Network packet since key input is client side but entity spawning (include projectiles) is server side.
You can take a look at this FCW page for general informations about Networking.

After some time, I've managed to get it to be able to summon a ghast fireball (as a test) on keybind, and it works fine, however it just spawns the entity, rather than giving it movement. This is the current code I have to summon the entity, I just need to add motion to it. And I do apologise, I'm just incredibly stupid, idk anything about Java - _ -'

 

public boolean handle(Supplier<NetworkEvent.Context> supplier) {

NetworkEvent.Context context = supplier.get();

context.enqueueWork(

() -> {

ServerPlayer player = context.getSender();

ServerLevel level = player.getLevel();

EntityType.FIREBALL.spawn(level, null, null, player.blockPosition(), MobSpawnType.COMMAND, true, false); }); return true; }

Look at the code in GhastShootFireballGoal.

You need to create the fireball, configure it, then level.addFreshEntity() to spawn it.
