Thanks! Glad it was helpful.

Well thank you, 5760!

Glad the video was helpful! I think the easiest way to do this in 3D would be to create an item prefab that takes in an itemSO instead of creating an item out of nothing like I do in the video. You would just instantiate the itemPrefab (in the same place I do in this video), and alter its appearance and name based on the itemSO (similar to what I do in the video, but without the sprite part). I hope that points you in the right direction.

@@NightRunStudio Ok, I will try, thank you very much!

I love it when people ask good questions! You've hit on the main ones so far... 1) Separation of Concerns and Encapsulation Holding your data in one place helps keep your other scripts more readable, and lets them focus on DOING stuff rather than remembering stuff. 2) Memory overhead Rather than adding all this data into your scene every time you add an enemy, there is only one copy of the stats that lives in your assets rather than in your scene 3) Easy Editing Once the project gets quite large, it's often easier to sort through scriptable objects when balancing enemies than it is to sort through enemies (where their stats could appear in multiple scripts and require you to sort through all sorts of other non-stat variables while you are editing them) I hope that helps a bit. SOs aren't the only way to handle this sort of data, but for these reasons it seems that most programmers are using them. Also, when it comes to a stat like Health, I would only store the base health in an SO. You would want to handle current Health and Buffs in a separate script which would load the max health to start, but then handle all of it's own current health. Again, this sort of thing makes more sense the larger your game gets. Cheers!

Do you mean like in the case of an enemy chasing an NPC or another type of enemy in addition to the player?

@ thank you for the response. Yes. I have 2 or things I trying to research. 1) having an enemy or even NPC attack another NPC. 2) how to recruit an NPC to an Army, and 3) how to recruit and make an NPC follow you.

@@totallyoffgrid3008 The code to chase other NPCs would work just like this, except that you'd have to add tags other than just the Player tag. That said, having enemies attack each other is a little more complex... that said, the code I use here would be a good foundation--you'd just have to build on it and balance it, The code for an NPC to follow you could work the same way as this chase, though you would probably want an offset, so they stop chasing once they get within a certain distance (like, say 1 unit).

@@NightRunStudio that could work. I am trying to create a multi-player capture the flag where you can take some troops and attack other regions. So I am trying to find a way where you could select about 7 NPCs and attack. Or if you wanted, you could have a friend fill a slot.

I do have another question…..do I need to add the script every time I insert an enemy sprite, or is there a way to populate my map by dragging and dropping and having the script and everything already attached…?

I hadn’t planned on adding this… but you’ve got me thinking so it might make an appearance. That said, this would actually be pretty easy to set up using UI buttons. You could mostly use our existing swap code, but rather than putting it in update and looking for a button press, you could put create its own method and have that get called by the button. You could get even fancier and create a separate method for each state type or something like that.

That’s awesome! Glad to hear the code is helpful for other applications.

I wish you the best irl! And hope you're able to get back at game dev soon. Cheers.

@NightRunStudio thanks ❤️

Thanks for the feedback. I’m learning that it’s nice if viewers have access to the assets if they want to follow along.

Yeah for sure

it was as simple as swapping the tags and editing the colliders. if anyone has this issue in the future this helped me hope it helps others

edit after swapping the next issue is have an enemy that you can damage but cant damage you currently looking for a fix

okay the issue following this discovery is that the collider thats set now moves if collided with by any solid object if that solid object is the player it pushes the collider out of the way so that you collide with the weakpoint causeing the enemy to die, so we need to keep the collider in the right spot instead of moving left or right when touched.

edit i found that when putting the rigidbody2d on the child it is what causes the collider to move and displace itself from the parent, but it is also what allows the player to take damage without it no damage can be done to the player. Dynamic causes the collider to shift, Kinematic works but effects gravity making the enemy and makes the enemy get stuck in the ground slightly, they can still move and chase properly but will fall slowly towards the ground if they enter the air. Static doesnt help at all.

all that is needed is to figure out how to add gravity to a kinematic rb2d

Haha. Nope, that’s definitely a first! Glad you enjoyed the video.

Sorry... just saw this, but not quite sure what you mean. If you give me a little more detail I'd be happy to help.

Does the enemy or player have multiple colliders? If so, that could explain the method multi firing. You could also add a bool variable (like hasDealtDamage) and 1) have the damage only occur if it is false; 2) turn it true right after the if statement; 3) then turn it false again after dealing the damage. That should work as a failsafe to only fire once.

@@NightRunStudio there is multiple i deleted one and its fixed now. but what if i want to damage the enemy by jumping on its head, would i have to decide where the damage gets applied?

One option would be to put the collider and damage script on a child object (while the main collider would be on another game object); another route would be to use a trigger for damage instead; or there’s the idea I mentioned earlier where you could create a bool to serve as a flag so it only gets applied the one time.

Thanks for the idea! I’m thinking of doing an updated version of this system in my RPG series (with some of the suggestions people have given me over time). If I do, will definitely look at adding things like a shop and storage.

@@NightRunStudio Thank you, would gladly watch, cuz i followed the inventory system tutorial, works like a charm. Now i gotta somehow make storages and stuff which is complicated especially because im new to all this game dev stuff

@4ebyre4naya34 yeah, it gets a little tricky. You could do something similar to what we do in the equipment series (when you drag the equipment from the inventory onto the character), but that’s a lot to figure out when you’re new. I think when I finally make this video I’ll show how to put the items into a dictionary for easier cataloguing and moving.

That is pretty normal. Eventually we should put some death logic into the game to avoid this. In the meantime, if you put if(player.gameObject != null) in the previous line it should fix the problem so that it only tries to run that line if player is active.

@@NightRunStudio Ok thanks!

No… I’m on a one week vacation, and now… the next one will drop in about a week.

@NightRunStudio olay

@@NightRunStudio how many vids will it take to complete it? Can I use the assets and some part of codes for my games?

The assets are free for commercial use (I included a link in the first video which has all the copyright info). The code is also all free to use. There’s no special copyright on the way I do things-most of it is pretty standard. I’m not sure how long the series will go. If it is popular enough I’ll keep adding topics for the next few months, that said, if it doesn’t catch on I might wrap it up soon.

@@NightRunStudio cool!

Are you using OnCollisionEnter2D to pick them up? Another method is to create a trigger that is larger than the collider that notices once’s the player enters.

I was using on trigger but I guess changing it it collision2d would be better?? Also could you do a tutorial for a flying 2d enemy platformer please??

I followed all these but it's confusing how to make the enemy stay flying with a rigid body2d and gravity bring on

Most of the time if you want the enemy to fly, you would turn off the gravity scale… unless of course you want it to drop and then lift off again (which gets more complex).

@@NightRunStudio So yeah i turned off gravity scale and when i attack the enemy i chases them and goes to the ground but doesnt go back up and just stays at the ground? any idea how to fix this?

That sounds like your brackets and if statement may be misplaced. It should only check for an enemy when you press the button. I would start by making sure the input check is working properly.

@@NightRunStudio sorry i wrote it wrong, the enemy is recieving damage only when i press the slash key, but i can deal him damage when i collide with his detectionPoint with detectionRadius, which is far further then the enemy collider

Same problem.Player attacks interact with detection collider.

@@Tofrellaz The easiest fix for this is to place: if (enemies[0].isTrigger) { return; } immediately after the line: if (enemies.Length > 0) In the DealDamage() method. That way, it wont mistake the trigger for the enemy itself. Hope that helps!

@@NightRunStudio Problem solved! Thank you mate! You're doing an amazing job, great teacher. Learning a lot from you! You deserve way more followers!

AHH i see my animations name was capital P instead of lower case!!

In episode 3 I do animating and flipping. And then in the ranged attack series I show how to set up the archer attacks (since they are more complicated). Each time we add a new state, I show how to set up the animator, but I don’t go over any other animations specifically.

@@NightRunStudio I mean for the goblin, and I've tried making a rpg before and I got stuck on the animations and the way you explain it is really nice as this is my 3rd day even having unity installed.

@PiglinGold99 gotcha. Yeah, I don’t show how to make the animations, but I do show the animator setup.

@@NightRunStudio Okay!

If you look in the hierarchy, are the enemies all spawning as children of the same object? If so, then destroying the parent would destroy all of them.

@@NightRunStudio Yes they are, thank you. Also I've started your RPG tutorial and just want to say it's one of the best tutorials for anything I've ever seen

@PiglinGold99 that’s high praise! Thanks!

Thanks a lot!

Great tip! Thanks for leaving the solution for others!

This sounds like a great idea. For my own project, I am also using inheritance. That said, when I first started with inventories, I found that adding inheritance to the other complications of an inventory system was often too much to handle. For this series I really tried to balance an adaptable, powerful system, while only introducing a handful of different coding patterns. That said, if you are comfortable with using inheritance, it will probably pay dividends in the future by making your code more maintainable.

@@NightRunStudio Thanks for the advice. I have been piecing together tutorials from various channels to create something of a game. The thing that is the worst is, getting really far and then having to restart because there is a better way. I was creating a Quest system based off your dialogue manager and someone else's quest system. I tried to use an npcquestpoint class that was inheriting from a questpoint class. There were so many issues that I decided to go in a different direction. I wasnt sure if it was my lack of understanding, or the fact im on a MacBook air, or what the issue was. I'm going to upload my first video tomorrow.

@@realmcraftchronicles It's always tricky... on the one hand, you keep learning better ways to do things, and want to start over to make your code more maintainable... but then there's also the fact that you could just do that infinitely. The trick is knowing when there's enough bang for your buck to make starting over worth it, and when you should just keep going so that you don't just end up in an infinite loop of restarting. (I'm saying this as the guy who just started rebuilding his game 2 months ago... hopefully for the last time this time!).

Is he dealing damage, but then floating afterwards, or is he failing to deal damage at all? If it's the former, then you probably just need to add some knockback effect so the enemy is repelled after you hit him. If it's the latter, then it sounds like your OnCollision method isn't firing properly. I would try adding some debug.Log messages (ex., Debug.Log("Test"); so you can find out which lines of code are firing and which ones are not. I would first ask 1) is the OnCollision method being triggered at all? 2) is it recognizing that the player has entered the enemy collider? Hope that points you in the right direction.

Glad to hear it! Thanks for the comment.

I’m toying with the idea of a quest and dialogue system for my RPG series, so this is definitely a possibility if there’s enough interest.

Which spot did you put it in the input manager?

@NightRunStudio InventoryMenu

Did you replace an existing button or make a new one? If the button isn’t doing anything, it’s possible you have it set up for a mouse or joystick instead of a key press. That’s one reason I usually suggest using the existing Fire buttons as they are set up properly for key inputs.

@NightRunStudio It's made for joystick, thank you

The system isn't inherently designed to do this, but you definitely could add that functionality. What you would want to do is: 1) Add all of the hearts that a player could possibly have right from the start. 2) In your Start() method, create a for loop that iterates through all of the empty hearts, turning them on as long as their length is not greater than your maxHealth. 3) The rest of your code would work as normal. 4) Now, whenever you gain maxHP you would want to call the same method you did in Start() so that it can turn on new empty hearts. It's hard to get it across without another tutorial, but hopefully that gets you off on the right foot.

Thanks for the ideas! I’m not totally sure just how far the series will go, but as long as people are watching I’ll keep adding stuff. More complex enemies are definitely on the horizon!

@ Great to hear that!

Haha! Thanks!

👍
