create an object called EnemyDrop add

[violet magnet]

we can thread it

[dark maple]

but what if i have multiple different enemies? I guess i could just ake a prefab for each enemy type, and the prefab woulld include itemDrop list

[violet magnet]

you don't need to

but you can if you want to

[dark maple]

??

[violet magnet]

would you like the code to handle the changes for you, or would you like to make many different prefabs

[dark maple]

code to handle the changes

[violet magnet]

right. so continue with what I mentioned

[dark maple]

ok i made the object

[violet magnet]

in that EnemyDrop script make a variable called private MyScriptableObject dropInformation;

in the object, you will need a sprite renderer, text, whatecver you want to display

configure that first, then show me what u got

[dark maple]

ok did this]

here

wait not a sphere colider i removed that

[violet magnet]

you alreayd have the scriptable object

so itemName should be a Text type, for it to be displayed

right?

(preferably a TMP_Text) as it's far superior to normal text

[dark maple]

ah i made it with just a string

[violet magnet]

?

[dark maple]

the scriptable

ill change it

[violet magnet]

no no

show me the scriptable object

lets go back to ground zero

[dark maple]

sorry, im really new to unity so

[violet magnet]

thats fine

[dark maple]

so

i made a scriptable

[violet magnet]

yep, show me it

[dark maple]

 [CreateAssetMenu(menuName = "Inventory/Item Definition", fileName = "New Item Definition")]
    public class ItemDefinition : ScriptableObject
    {

        [SerializeField] private string _itemName;
        [SerializeField] private bool _isStackable;
        [SerializeField] private Sprite _inGameSprite;
        [SerializeField] private Sprite _uiSprite;

        public string itemName => _itemName; 
        public bool isStackable => _isStackable;
        public Sprite inGameSprite => _inGameSprite;
        public Sprite uiSprite => _uiSprite;


    }

[violet magnet]

ok, that's perfectly fine. leave it alone

[dark maple]

ok

[violet magnet]

these

should these not be TMP_Text types?

to show the item name etc

[dark maple]

ahh ok yes

done that

[violet magnet]

now configure it in the object inspector

drag and drop the references, show me a pic of that once done

[violet magnet]

drag in the text objects

this is for the drops only btw. for UI you'll do that yourself

[split prism]

How does a ScriptableObject differ from a MonoBehaviour with serialized fields?

Wait, I should just watch the tutorial. Ignore me.

[violet magnet]

Grand. now write this:

public void Initialize(ItemDefinition droppedItem)
{
   dropInformation = droppedItem;
   name.text = dropInformation.name;
   //continue for all information;
}```

edited slightly.

I notice that you made dropInformation public

Don't do that. make it private

it should not be exposed

[dark maple]

oh, wait so i assign nothing to it?

or serializeField?

[violet magnet]

look in the function I made

it gets assigned via code

so keep it private, null

[dark maple]

okk

done

[violet magnet]

you wrote all information in the init function?

show me

[dark maple]

public class EnemyLootDrop : MonoBehaviour
{
    private ItemDefinition dropInformation = null;

    public TMP_Text itemName;

    public TMP_Text amount;
    public bool isStackable;
    public Sprite itemSprite;

    public void Initialize(ItemDefinition droppedItem)
    {
        dropInformation = droppedItem;
        itemName.text = dropInformation.name;
        isStackable = dropInformation.isStackable;
        itemSprite = dropInformation.inGameSprite;
        //continue for all information;
    }
}

is should maybe remove the amount

[violet magnet]

why have you changed SpriteRenderer to Sprite

the ScriptableObject holds the sprite

and we want to Display that onto the sprite renderer

right?

[dark maple]

ahh the ItemDefinition had just the sprite

[violet magnet]

yes, as it should

and this class, should display that sprite onto a sprite renderer

[dark maple]

fixed it

itemSprite.sprite = dropInformation.inGameSprite;

[violet magnet]

ok, we're nearly done

now, go to your Slime enemy script

[dark maple]

mhmm

[violet magnet]

[SerializeField] private EnemyLootDrop lootPrefab;
[SerializeField] private ItemDefinition lootInformation;```

write these

also, prefab this loot object we've just made.

then plug in the references

show me once done

[dark maple]

a small question

[violet magnet]

shoot

[dark maple]

where should the TMP text object be?

in the hierachy i mean

[violet magnet]

I don't follow

[dark maple]

as a child of EnemyDrop?

[violet magnet]

yes

depends how you want your drops to look, it's a design question only you can answer

[violet magnet]

looks fine to me. how does it look in scene view?

[dark maple]

hmmm i cant acually see it

maybe i need a canvas for it?

[violet magnet]

if its UI text, you wont be able to

no, make a 3D text object

[dark maple]

ooohhh

ok

made the prefab

ill adjust the size of text later lol

[violet magnet]

cool, have you wrote the 2 lines in the slime script and dragged in the stuff

I guess the sprite renderer is hidden by the text? since I don't see it

[dark maple]

yes

[dark maple]

its just below the plane

[dark maple]

done

[violet magnet]

sick

now, when enemy dies

simply just..

EnemyLootDrop drop = Instantiate(the loot prefab, pos, rot);
drop.Initialize(theInformation);

and you're done

[dark maple]

okk

i wrote it

[violet magnet]

now kill a slime

and show me a picture of what happens

[dark maple]

here

seems like it is working

wow

[violet magnet]

you can remove the one you have justi nthe scene

since you've prefabbed it now

[dark maple]

ok

[violet magnet]

remove the amount TMP text

as thats just for your inventory I'd think.

that's a seperate thing

I would also advise putting your sprite renderer as a child

so then you can scale it independantly from the root object

[dark maple]

oh ok

[violet magnet]

(always best to keep root objects at 1,1,1 scale)

but now do that, and scale your text properly so it's not just massive and make a new video (and move text up)

(and scale the drop sprite up abit, seems abit small to me)

[dark maple]

ok ill do that

[dark maple]

so just make an empty obj with sprite renderer component?

[violet magnet]

correct

[dark maple]

ok all done

[violet magnet]

Does it work

[dark maple]

yep

[violet magnet]

Sik, do you have other enemy types yet? or atleast a different drop

use that potion bottle

make a new SO instance, call it "Heal potion"

[dark maple]

yes i have another drop

[violet magnet]

and drop it into the enemy loot information of the slime

[dark maple]

already done

[violet magnet]

ok ezpzp

[dark maple]

here

[violet magnet]

ezpz right?

[dark maple]

yeah

oh but what if i want slime to have both drops?

i know to make an array and loop through it i suppose

[violet magnet]

change
[SerializeField] private ItemDefinition lootInformation;
to
[SerializeField] private List<ItemDefinition> lootInformation;

//on death:
foreach(ItemDefininition lootInfo in lootInformation)
{
   Vector3 dropLocationOffset = Random.onUnitSphere * 3; (3 == some arbitary radius)
   dropLocationOffset.y = 0;
   Vector3 dropLocation = transform.position + dropLocationOffset;

   EnemyLootDrop drop = Instantiate(lootPrefab,dropLocation,...);
   drop.Initialize(lootInfo);

}```

randomized drop location around death point, so they try to not double up on one another

try it with like.... 10 elements in the list. lets see what happens

[dark maple]

oh god

chaos will happen

[violet magnet]

perhaps

but it'd be good to see

[dark maple]

yeah it works

[violet magnet]

cool, I'll tell you the next steps, but that will be your homework

[dark maple]

but ait

they are all under the plane

not on lvl with the slime

[violet magnet]

Vector3 dropLocation = transform.position + dropLocationOffset; I used transform.position for the spawn location

if thats incorrect, use what you have been using

plus the offset

[dark maple]

i guess easy fix: dropLocationOffset.y = 0

so 0 is added to the y value

[violet magnet]

which is correct, as we don't want a randomized spawn height

we want it to spawn at deathLocation.y, right?

what did you use before, for instantiate?

[dark maple]

now it works perfectly

[dark maple]

just position

[violet magnet]

cool, though 3 is abit much it looks like hehe

try like 1

[dark maple]

yeah ill adjust it now haha

much better haha

[violet magnet]

nice, right so back to homework task

EnemyLootDrop will handle the player picking up the loot, either a magnetic effect, or a simple OnTriggerEnter.

When you pick up the item, you could also add a call to an InventoryManager. to add it to your inventory.

the EnemyLootDrop already has the information of the item stored. so it should be simple enough to pass that to the inventory manager, to add the stats etc to the correct thing.

how you go about doing that, is totally upto you.

[dark maple]

ahh right ok

[violet magnet]

ping me at somepoint in the future when you've figured it out, I'd like to see the progression

Stretch task:
-Make the sprite renderer bob up and down (Research: move Y posiition of sprite renderer object via a Mathf.Sin wave.)
-Make the text only visible if the player is within X units of the dropped item.

[dark maple]

i suppose this will change for each enemy, so would i need to assign the loot manually?

[violet magnet]

correct

[dark maple]

ahh ok

maybe better if i made a prefab for each enemy type?

so i can just instantiate the slimes, all will have simmilar loot, wtc

[violet magnet]

for the loot? no, you wuold still need to drag in the prefab anyway

so what does it matter

[dark maple]

ohh

[violet magnet]

theres only so much automation you can do

[dark maple]

dang

ok, ill bear that in mind

but still upon instantiate, would i still need to assign loot?

[violet magnet]

Can you explain better

[dark maple]

if it is assigned beforehand in prefab, when i instantiate the enemy prefab, would i still need to assign it again?

[violet magnet]

No

[dark maple]

the loot

ohh ok thats good then

[violet magnet]

this is why I asked this right at the start

[dark maple]

yeah but i suppose i will need to make a prefab of each enemy type...

or maybe a scriptable object is better?

[violet magnet]

thats how I do it in my game

each enemy is its own prefab

[dark maple]

yeah it seems better on my case too

[violet magnet]

but they all use the same EnemyAI script

it's abit complicated

uses inheritance and ScriptableObjects for their attack data etc

[dark maple]

for roaming and chasing? yes most likely

[dark maple]

yeah attack data will change, and maybe their range of sight etc

[dark maple]

here i got it to add to the inventory

[violet magnet]

Very nice

[dark maple]

yesss sir

thank you for the help by the way

very much appreciated 😄

[violet magnet]

No problemo!

[dark maple]

I want to make some pop up animation, and add gravity to the item too, so that it always falls on the ground

[violet magnet]

for popup: Please look into Dotween

[dark maple]

(Event when i hit the enemies mid- air)

[violet magnet]

it'll change your life

[dark maple]

i did

[violet magnet]

https://streamable.com/o1n2tw

[dark maple]

my slime jump animation and Hit animation are done using DOTween

[dark maple]

Wow is this your game?

[violet magnet]

Yep, it's in my bio

[dark maple]

looks so stylish!

[violet magnet]

Not too many games like this around

[dark maple]

yeah!

is it a hack n slash?

[violet magnet]

Dungeon Crawler rogue like

[dark maple]

🤩

my favourite genres

[split prism]

I'm doing one of those but 2D.

[violet magnet]

I think I have my twitter linked to my discord, feel free to follow me for updates

[dark maple]

im gonna make something similar but with Octopath traveller graphics (2.5D)

something like this, maybe not this beautiful, but close

[dark maple]

nice

[dark maple]

update

Got the items to jump when they spawn

[dark maple]

    private void ItemDrop()
    {
        foreach (ItemDefinition lootInfo in lootInformation)
        {
            Vector3 dropLocationOffset = Random.onUnitSphere * 1; //(1 == some arbitary radius)
            dropLocationOffset.y = 0;
            Vector3 dropLocation = transform.position + dropLocationOffset;

            GameItem drop = Instantiate(lootPrefab, transform.position, Quaternion.identity);
            drop.Initialize(lootInfo);

            drop.transform.DOJump(
            endValue: dropLocation,
            jumpPower: 0.2f,
            numJumps: 1,
            duration: 0.5f);
        }
``` here's the code, just added DOJump

[violet magnet]

if you want to clean it up, you can do all of that inside Initialize

but hell yea dude, looks rad

[dark maple]

yeah but then the dropLacation will also need to change, etc, i just did it here for convinience, andin the future, i might wanna animate the items in a different way, depending on how they are spawned, etc.
