How to create pokemon the copyright free version
Ayy it's you! :D you helped me with code earlier today!
Or just ROM hack (since then you have all the Pokémon data)
I spend a week setting up the canvas before doing anything.
pocket rocks!
@@user-zl5cv6vw2m come on help the poor guy, yeah that videos quality is a bit low but come on! I shared all what is important aye?
There is a mistake in the logic that handles Player's turn and Enemy's turn. 20:35
You need to set the ENEMYTURN flag immediately after the player has chosen an action.
Right now as you can see it waits for 2 seconds, in that timeframe we still have our PLAYERTURN, meaning we can spam the attack button and start as many attack coroutines as we can.
By changing to ENEMYTURN immediately, we block the attack button's function as it is only available in the player's turn.
My man you got it
Thanks for pointing that out wow
I did it like this:
IEnumerator PlayerAttack()
{
bool isDead = enemyUnit.TakeDamage(playerUnit.damage);
if (isDead)
{
state = BattleState.WON;
enemyHUD.SetHP(enemyUnit.currentHP = 0);
EndBattle();
}
else
{
state = BattleState.ENEMYTURN;
enemyHUD.SetHP(enemyUnit.currentHP,);
dialogueText.text = "You deal " + playerUnit.damage + " damage...";
yield return new WaitForSeconds(2f);
StartCoroutine(EnemyTurn());
}
}
AND:
IEnumerator PlayerHeal()
{
playerUnit.Heal(5);
state = BattleState.ENEMYTURN;
playerHUD.SetHP(playerUnit.currentHP);
dialogueText.text = "You healed for 5.";
yield return new WaitForSeconds(2f);
StartCoroutine(EnemyTurn());
}
I handled this by having an intermediate state called WAITING. This is a "blank" state that prevents the button spam, keeps me conscious about state switching as I'm programming, and also a state I can use later to let animations play out.
Just an extra tip and heads up for the fellow learners:
You can still attack during enemy's turn because your Attack & heal buttons still show up and is enabled during enemy's turn so make sure you add an extra method that either disables or hides the button when its the enemy's turn and then ReEnables/Unhide the button when its your turn. Should be really easy to implement, just look up the tuts, they are easy to find.
*enemy begins attack*
*_player violently slaps them again_*
Actually you cannot because of the state machine. The buttons are still there, but they do nothing during gamestate.enemy turn. still a good UI tip though
If you spam the attack button during your turn, it will start the coroutine several times until the first one to change the state. This will still perform several attacks in one turn.
IF statements work for this, correct? Like if it's the enemy's turn, disable attack or something?
@@caidenbond1988 yeah it will
When you're just starting to create an RPG game and this pops into your recommended...
One stack of likes
I need help: do you know some way to make random encounters or some video that talks about it?
@@se9979
If you're thinking about a random encounter system like Pokemon,
Add a property to tiles for if they are dangerous or not.
Have a list of encounters your player can encounter in that general area, and perhaps set the ID for these encounters in individual tiles if you want to get more specific.
Perform a random roll when the player steps or turns within one of these dangerous tiles, (Pokemon also makes the chance at an encounter more likely if the player is running.)
Then store relevant level data before transitioning to the battle scene, and when it's over, load your player back where they were.
(I'm still really new at game design, but I think this is how it's done from a logistics standpoint.)
@@redgeoblaze3752 That sounds right.
a role playing game game?
I literally spent a week building a turn based combat system then this comes out

I can't believe that after years online I actually saw an Ad that is actually useful! Milanote sounds like what I've been looking for years!
you can just use trello, much easier
Probably bot
Evernote?
@@se9979 No, milanote actually seems really good from what little I've done with it. Perhaps there's some paywall that i haven't come across yet, but it does actually seem really helpful for planning stuff.
I definitely sound like a bot. I recommend you give it a go though.
Milanote is great 👌
I know you recently came back from the gates of death *spooky* and started to make new videos!! I loved the content, thank you for that, I'm not a programmer but I could finished the turned base combat you purposed and the most great party of it is that I was able by myself to clear all the bug I had and made it work!! I feel really happy for achieving that!! Thank you, Brackeys!! Your contents are awesome!! We're glad you are back =]
THANK YOU SO MUCH FOR MAKING THIS!!!!! Seriously I can't express how difficult it has been to find a comprehensive tutorial on this subject (paid for or for free). You have saved my game man. I'm seriously so grateful. OTL
The sheer quality of this tutorial is amazing
After I followed this tutorial, I found Infallible Code's video "How to Code a Simple State Machine (Unity Tutorial)." It shows how to create a state machine and the tutorial is based somewhat off of the battle system shown in this video. I recommend that you guys check it out; it'll help you organize the code for each individual action (attacking and healing) better.
Dude you're a life saver. This is a great place if you're new to unity and learn. Thanks for everything.
Been wanting a basics turn based combat system forever, thanks!
I learned a lot from this. I am currently trying to make a rpg with 6 party members and each taking a turn. Now to sit at the code screen and stare till things come to me.
Great video! As usual, useful content right when needed.
Awesome video and awesome AD, perfectly integrated in the content and actually showing how it can be useful for development.
I was literally looking for milanote after I saw a indie dev using it but I didn't know what it's name was. I thought it was notion but couldn't find the templates that matched this look so ruled it out. Thanks brackets! Not only for the great tutorial but also finishing my quest to find it!
I love your videos, and specially more nowadays. You've improved so much. I was watching for example one of your old videos a out parallax effect in 2d games and I have to say it, oh God it was so hard to watch. In those days you explained everything while you were writing the code like in live video, it was so slow and painful compared to your new videos lol still very useful all of them, but maybe you should remake a few of the more dense and long ones to this new format.
Perhaps the changes in Unity 2020 will be reason enough to update old video tutorials in the new style
Blender Guru did something similar when Blender 2.8 came out. So, why not the same for Brackeys?
It's amazing how you help people to grow in game development. I love your channel :D
As always brackeys, you have an answer for every problem I encounter. Thanks man!
Thank you! This is just what I needed at like the (strangely) perfect time!
for people who are about to watch this video, 100% WORTH IT!! Follow along the whole 30 mins. completely customizable and very user friendly!
Nice. I'm sure a lot of students I know would love to see this stuff. Great first step.
4 Minutes in and its pass 3 PM ... Great guide ! having fun modifying with free art and thinking what changes could be made to the UI Would love to see more guides for rpg , Especially how to trigger the turn base combat from another menu.
Thanks for the video !
"A wild The Rock approaches..."
I love that you kept it like that. LOL
yayy it's apparently Sunday again! good to see you post :)
Really lovely. A beginner here, now I think I'll be capable of implementing this approach to mine game. Thank you!
Thanks so much! These tutorials make my day a whole lot better!
You looks great today! Ou btw congrats on 900k subs!!
I was just looking for this... Perfect timing
Sweet man! Thanks for making this :)
This tutorial gave me nostalgia and inspired me to create a small pokemon game clone. I've also created a pokemon game tutorial series in unity to help anyone who wants to create something similar.
Good intro to the topic, wouldn't mind a whole series on fleshing this kind of system to show off better coding techniques & some juicy fx! \o/
This was a great video. Learned a lot from implementing it while following your example.
That script was very structured love it
This is actually what I need and its not really that difficult, thanks again!
Oh shoot, I was just gonna have to research about programming turn-based combat and the report is due tomorrow then I saw this in my subscription feeds! Thank you!!!
Hi Asbjorn, we missed you in Unite India. But happy to see you in FaceTime. Met Andreas and I conveyed my hearful thanks to Brackeys team. Wish you all the happiness in life. Thanks Guru.
Wow I didnt know we could call "yield return WaiforSeconds" multiple times in one IEnumerator!! So much cool ideas just popped up in my head XD
This is awesome! I’m just starting to learn and this was very helpful. Thank you ^_^
Thank you so much I have been looking for a good turn based tutorial
All my questions answered in one video. Thanks!
I have no idea how he manages to speak and type this fast at the same time though...
Gotta say that was the BEST AD EVER!
It was nicely integrated, teaches people how to use a cool tool and IS part of the larger Game Development tutorials that MOST don't seem to show. YAY I did all this, with a TON of work but its like 10 mins of video.
I mean great job, I think Milinote is great, I like its drag and drag. I know a Dark Theme would help, from my browser, but those sites REALLY are missing that, not sure if it has it.
Just signed up, COOL you can increase the font, and SO far does work NICELY with the Dark Theme browser extension I use.
MY GAWD Why is Unity not charging me $1000 for my use of Dark THEME! - ITS free Unity IMAGINE that!
Just in time for my project!
Love your videos btw.. Great content!
Will you make an advanced tutorial about water and maybe swimming?
That's funny.
Just today I've been wondering how to implement something similar. Great!
when adapting the contents of this tutorial I decided to change one key aspect.
I find it a little silly to adapt a creature's stats to a prefab, create objects from prefabs every single encounter and every time you catch something etc.
So instead, I just load the specific sprite that matches the fighter's name from Resources and keep all the fighter-specific data in its own instance of class Creature. That way it persists across all systems of the game.
I am personally attmepting to recreate a childhood flash game in unity, it had a turn based combat system and a lot of mechanics! So thank you!
This was an awesome tutorial. You are one of the best Unity tutorial channels I've ever run into!
However, I found a HUGE problem in the way this battle system works. There is now way to check if the player is spamming the Attack or Heal button, so when the button is spam clicked, you can attack or heal multiple times.
I fixed it by creating new BattleStates called "PLAYERATTACKED" and "PLAYERHEALED" and immediately switching to that state when the PlayerAttack() or PlayerHeal() is called.
Thank you so much!
Hey Asbjørn, so much to say. Firstly a massive thank you for helping me get into game dev. Less than two years ago I knew nothing of this world, but since watching your videos and using them almost exclusively as a learning resource, I've gone from zero to...competent coder (bet you thought I was going to say hero). I was saddened to hear your announcement on ending your Brackey's videos, but as the old saying goes, don't be sad that it's over, smile because it happened and thanks to the medium, your youtube videos remain and are still a vital resource that I plunge into on a regular basis. Your professional approach to making clear and informative tutorials were (and still are) an absolute God send. I have you personally to thank for this new skillset and wish you the best of luck for the future.

Seems like something you should continue haha.
Extremely helpful video. Really helped out, and while I will definitely add more to it, and change it so that it fits my vision for my game more, this is really useful for getting the basics down.
However, I did notice that if you keep clicking on the player attack, it will cause the damage to just continually go down. I think I was able to solve this by changing the state in the PlayerHeal and PlayerAttack methods before waiting, since that will make it so that the attack and heal methods just return without doing anything else.
The best youtube channel if you want to learn unity3D! Thanks!
In the TakeDamage method you could directly return currentHP
Best unity tutorial channel ever!
There is a small problem in this project. You can spam the Attack and Heal buttons for 2 seconds because the battle state doesn't get changed immediately. I would suggest to add a new battle state like "PLAYERACTION" and change the state to that on line 62 at 20:12 before you call the Coroutine (or inside the Corioutine but before the 2 seconds wait).
what would that look like?
"dwayne" johnson the "rock"....... Thanks for the tutorial. You are awesome.
OMG I LOVE U
This is EXACTLY what I wanted YESS ❤
Nice video, helps me a lot.
I need to make a Turn-Based Combat system for an AI tech demo for a class, so this was timed AMAZINGLY!
I think it’s the first time ever that a sponsor convinces me to try the product that it sells!
tbf the advertisement was also really clever, with him using the product being advertised throughout the whole video to show it off at the same time as teaching you gamedev skills. i'd say it was Brackeys that convinced you more so than the sponsor did :)
Brackey saving my day... Again! thank you very much!
That's cool !
"The Rock vs An actual Rock" 🤣
Просто спасибо тебе за твои гайды, ты просто лучший. Столько всего пересмотрел на ютубе и твои гайды просто лучшие
finally, i waited for this
Thx, that's what I needed
I say thank you. You're a real lifesaver, i've been trying to do this since march! Been struggling with those unholy finite state machines with variable degrees of success.... If i ever finish my game i'll be sure to thank this channel
I've just tried it. It has worked perfectly fine (well, with minor bugs but nothing serious). This tutorial is easy to follow, and it is really easy to modify the code. I've been researching a bit and some people do actually use corroutines as FSM. WELL, my other projects will surely work really fine now!
@@AndersonReis42 great job:) by the way, what are you working on? Might wanna play!
@@MonochromeChromosome oh, nothing too ambitious. Just a "chicken fighting game". Chicken fights are a brazilian meme :)
But i'll use the algorithm later to develop a game where you train a boxer to his way to success. Things are in a very early development stage however
You make this look so easy XD
I suck at making turn based games, hopefully this will help :)
I like this system. I also added my own implementation of the ATB meter from the final fantasy series.

That Battle shown in the checklist is the battle from pokemon ruby and sapphire where you choose your starter to save Professor Birch from the poochyena
Thanks for the help i am working on an rpg for my coding class and this was a big help
I like it! Very good video, thk you!
Here is a quick breakdown of what would be really nice for milanote to be able to
* Create references to other boards anywhere (like a hyperlink)
* Create a KanBan board that can connect to all todo lists (KanBan boards are used by a lot of professionals for organizing which todo tasks are more important to least important and include a backlog)
* Better tutorial and/or documentation if not already available on how to use milanote, if available make it easier to access
I'll add onto this if/when I come up with better and/or more ideas. This is just my first impressions messing around with Milanote for an hour. Let me know what you think :)
Otherwise this is a really good tool for organization!!!!
Good channel. Keep it up !!!
Hey nice tutorial, would there be a chance for an extended tutorial which covers multiple combatants and different attacks/actions per combatant?
Exactly what I was looking for this week. Nice work.
very veeery nice tutorial, thanks, you are a pro
A video about SOLID principles in Unity would be pretty nice
Will you do multiplayer(photon) version of this? I need multiplayer turn-based game tutorial but I didn't find.
thank you brackeys!
Please make a video about camera and scaling the ui, it is so hard for me to get this right :)
btw, love your content!!!
I recommend changing the UI scale mode on the canvas to: scale with screen. It’s a lot easier to work with trust me.
Just worked this out, works great! Only difficulty I have is that whenever the enemy attacks, all it says is "enemy (clone)" rather than the name I assigned it. Aside from that tiny issue, everything works great!
That is because you are likely referencing the name of the object "enemy(clone)" instead of their assigned name. Perhaps you could make their name a bit more clear, that way you can make a clear reference to the unit?
@@RagoxHatena I just figured it out last night, but thank you for the reply!
HOLY FUCK, this couldn't have come at a more perfect time, I have a tactics move system that's broken and this may help me buff up the turn based manager
Thanks brackeys!
just what i needed
How would you change the BattleSystem code to have multiple enemies or multiple player-controlled characters, like in Final Fantasy?
Ty sir! subbed :)
HES BACK
OMG FINALLY, I LOVE YOU. 💙
love your vids :)
Are you going to make tutorials for Unity ECS once Entities 1.0 is released?
Honestly, i doubt that he understands ECS.
I also doubt that ECS is something that will be well recieved by the larger part of the community.
ruclips.net/video/ILfUuBLfzGI/видео.html
Thank you for great videos every week!! This's I've been waiting for.
By the way, I found a bug in the code. If I click the attack button or heal button again and again in my turn (before WaitForSeconds() ends), I can attack or heal many times in 1 turn. After my turn ends, I get attacked many times in 1 turn.
A solution for this is add new BattleState named "PLAYER_CHOOSED_ACTION". When the attack button or heal button was pressed in player's turn, change the state PLAYER_TURN to PLAYER_CHOOSED_ACTION and fix the if statement such like "if (state != BattleState.PLAYER_TURN && state == BattleState.PLAYER_ACTION_CHOOSED) return;".
Of course to fix this, we can change the UI as soon as the attack button or heal button was pressed.
Thanks for reading and happy coding!
I had the same issue and solved it similarly:
public enum ButtonState { ACTIVE, INACTIVE }
Initiate it to ACTIVE in the Start function and set it to INACTIVE in the Button Functions before PlayerAttack or PlayerHeal are called. Reset it to ACTIVE when the Enemy Turn ends.
@@MaxParasite Alright, I'm confused. Where exactly am i putting the inactive and active and how do i make them affect the buttons i want?
As a solo developer, I tried Milanote and found it to be a much better, tailored experience than something of the likes of Trello. I had been using Trello up until now, and while it serves its purpose well, I will be using Milanote from now on. Thanks @Brackeys :D
That awfully sounded like a paid comment, yikes lol
Simple question : imagine we are creating some kind of pokemon game. Is it better to create two different scenes for combat and world travel, or to manage to make both work in one scene ?
Merry Christmas from Majou ;)
is there any chance someone know how to manage multiple character in one team such as FF
I made different attacks possible by making a scriptable object to store attack data and a ratio probability system for enemies
Good tip!!
He did it again!
