Let’s Learn Godot 4 by Making an RPG — Part 13: Enemy Dropping Loot on Death🤠

We can finally shoot and kill our enemy, but we can do one better. I want us to upgrade our enemy’s death function so that our enemy drops loot that we can pick up. This loot drop will spawn at a 90% chance, and the loot will be randomized from our Pickups enum. This means our enemy might drop either ammo, a health drink, or a stamina drink.

· How to randomize percentage and Enum return values.

In our death conditional in our damage() function, we need to use our randomized method to randomize the loot change percentage. If the value is less than 0.9 (90%), we will randomize a pickup. This pickup will also be randomized according to the number of enum values we have, which is 3. This pickup will then be added to our scene and spawned at our killed enemy’s location.

    # older code

    #will damage the enemy when they get hit
    func hit(damage):
        health -= damage
        if health > 0:
            #stop movement
            direction = Vector2.ZERO
            #stop health regeneration
            #trigger animation finished signal
            is_attacking = true     
            #Finally, we play the death animation and emit the signal for the spawner.
            #drop loot randomly at a 90% chance
            if rng.randf() < 0.9:
                var pickup = Global.pickups_scene.instantiate()
                pickup.item = rng.randi() % 3 #we have three pickups in our enum
                get_tree().root.get_node("Main/PickupSpawner/SpawnedPickups").call_deferred("add_child", pickup)
                pickup.position = position

What is call_deffered?
call_deferred is a method that allows you to defer the call of another method to the end of the current frame or cycle. This can be particularly useful in situations where you want to make changes to the scene tree or other objects but don’t want those changes to take effect immediately during the current function or signal.

If you now run your scene and you kill your enemy, they should drop loot at a 90% chance. You can lower this value to 50% or 60% if you want — set it according to your preference of how probable you want your enemy to drop loot on death.

Now that our enemy drops loot, we don’t have to continuously find pickups. In the next part we will add the functionality to our enemy to be able to shoot at our player and damage us. Remember to save your project, and I’ll see you in the next part.

The final source code for this part can be found here.
