So my code is supposed to discover a new recipe when you pick up an elytra but i cant seem to do it

So like I said the code is supposed to discover a new recipe.

Code:

package me.sleepyhere.betterelytra

import org.bukkit.Bukkit
import org.bukkit.Material
import org.bukkit.NamespacedKey
import org.bukkit.entity.EntityType
import org.bukkit.entity.Player
import org.bukkit.event.EventHandler
import org.bukkit.event.Listener
import org.bukkit.event.entity.EntityPickupItemEvent
import org.bukkit.inventory.ItemStack
import org.bukkit.inventory.ShapedRecipe
import org.bukkit.plugin.java.JavaPlugin



class Elytra : JavaPlugin() {
    @Override
    override fun onEnable() {
        logger.info("Better Elytra Enabled.")
        var elytra = ItemStack(Material.ELYTRA, 2)
        var key = NamespacedKey(this, "Elytra")
        var recipe = ShapedRecipe(key, elytra)

        recipe.shape("DED", "LSL", "LSL")
        recipe.setIngredient('D', Material.DIAMOND_BLOCK)
        recipe.setIngredient('E', Material.ELYTRA)
        recipe.setIngredient('L', Material.LEATHER)
        recipe.setIngredient('S', Material.STICK)

        Bukkit.addRecipe(recipe)

        fun onListening(listener: Listener) {
            server.pluginManager.registerEvents(listener, this)
            class MyListener : Listener {
                @EventHandler
                fun onPlayerJoin(event: EntityPickupItemEvent?) {
                    if (event != null) {
                        if(event.entityType == EntityType.PLAYER) {
                            var elytra = ItemStack(Material.ELYTRA)
                            if(event.item == elytra) {
                                val p = event.entity as Player
                                p.discoverRecipe(key)
                            }
                        }

                    }
                }
            }
        }
    }

    override fun onDisable() {
        // Plugin shutdown logic
        logger.info("Disabling . . . BYEEEEEEEEE")
    }
}

And Btw Im using Kotlin
So Theres no error but nothing happens when I pickup an elytra.

 

I believe you need the @EventListener notation, but I don't code in Kotlin so I'm not sure how you'd do that... If you add prints to different locations in your event function, do they ever print? Can you confirm the event is ever being fired?

 

Ok, I'll try that.

I tried it but I cant seed to add it. I already have eventhandler notation but I think I didn't import event listener idk how

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

I fixed my code now but it still doesn't work Nothing is firing...

                            val p = event.entity as Player
                            p.discoverRecipe(key)
                        }
                    }

                }
            }
        }
    }

    override fun onDisable() {
        // Plugin shutdown logic
        logger.info("Disabling . . . BYEEEEEEEEE")
    }
