[@PandemoniumGameDev]

Thanks for everyone for the patience, this one was a pain to record, I managed to mess up the video a couple times and had to redo it. Hope everything is clear and let me know if you need help, also check the GitHub project if you need the code: github.com/nickbota/Unity-Platformer-Episode-10 For everyone who's getting UnassignedReferenceException when your fireballs hit something change this part of the code: collision.GetComponent().TakeDamage(damage); to this: collision.GetComponent()?.TakeDamage(damage); The ? will check if the object has a Health component before trying to damage it.

lovely videos, you are an excellent teacher, thanks for helping us.

Hello sir when I hurts my enemy he get die but still moving please sir tell me

[@skyherald7390]

Epic video! idk why the channel is underrated I guess no one wants to become and Albert Einstein like you!(im not smart) Ahem.. Btw the EnemyFireball is not visible when he the enemy shoots but the invisible fireball still hits the player the sorting layer on the fireballs is set to Foregrounds so idk the problem Please Help dude!

[@snakejaguar477]

I have a problem where the person dies but keeps moving when I move over him.

[@mashupsbyrens285]

Idk if I'm too late; but you can click the + icon in the MeleeEnemy/RangedEnemy script, and select the EnemyPatrol game Obejct in it. It would load up the script in it, and then it would also disable the EnemyPatrol script@@snakejaguar477

[@mrsworder]

Probably one of the best unity tutorials creator, you dont just make us copy the code( yes doing this we would create a game, but we don't learn nothing about how to make a game by ourself) , but you explain well how the code we just typed works! Sad to see the channel really underrated :(

[@PandemoniumGameDev]

Really glad to help! Don't worry it's been growing steadily, also I need to be more consistent and put out more stuff

[@skyherald7390]

Yo bro can you help me with the DamagePlayer() Event in Melee Attack in the script it is saying it is unused and in the unity editor its saying its not supported so how do you fix it? pls help Epic Tutorial btw Love it!@@PandemoniumGameDev

[@tapthelvete]

I've been looking for reliable and easy to understand Unity tutorials and I hadn't found one... Until now. Your explanations are wonderfully constructed and I actually feel like I am learning. It's quite sad to see how little subscribers you have, but at least I can contribute by adding one more! Thank you for these videos and I hope you have an amazing 2022!

If you want a different enemy sprite that looks a bit different there is also ninja sprite sheet on the unity asset store by the same creator as the knight one.

[@danieltai6494]

If someone's fire ball is shooting without any cooldown, go to animation, and check the transition from ranged attack back to idle and make sure there isn't a trigger(ranged attack) there

[@anastarek4491]

This is the best channel in the world. I learned many things from you and applied them and became good at making games. Thank you.

Awesome videos! Are helping me a lot to learn how to proper use Unity

[@thesilentwisp]

Thank you so much for releasing a new tutorial. Been following this series and making my very first platformer! Out of curiosity, why not use the new PlayerInput system for the controls, or the Cinemachine for camera movement?

[@PandemoniumGameDev]

Hey there, it would've been a bit easier probably but I wanted to start with the basics not use any packages.

[@rorywalker4770]

Thanks for your tutorial! Is there a reason why you keep using Vector3 for a 2D game?

Wow... Underrated... Code actually works unlike other codes.

[@marekpuchon4878]

This is absolute awesome. I have just one question. When i create event on end of animation die when i kill enemy he stop using those two scripts but he will not disapeare and because of the script enemy damage can still hurt me.

Great Tutorial :D Love it :)

[@waltersattazahn1480]

Another good video. I got everything to work, and was able to solve any issues I had. I would like to share that the last issue I had was that my RangedEnemy Firepoint was not changing direction with the RangedEnemy's direction. I found out that the FireballHolder(the empty object that holds the Projectiles) had to have a similar setup as the Player in that it cannot be a child of the RangedEnemy.

[@frederictang6599]

thx you saved me

[@danieltai6494]

ur a life saver man

[@GeRgOyt]

'Guess i'll die' lmao you're the best :D

[@moedip7240]

My ranged enemy keeps shooting fireballs even when the player is out of sight while he is walking in the opposite direcetion! Any reasons for that? thanks for the videos, great tutorials as usual.

[@prochysolaire9055]

I dont know why but i have the code completely same but my RaycastHit2D hit does not trigger when player is inside the red box

[@sogyshorts5662]

did u solve it? and if yes, how?

[@scorpiusjones5436]

Great series as always! Quick thing I found at the end of this tut is the EnemyPatrol object can be very specific about what variables are active in it. You have to plug these variables in when we first made it (I think they are "Enemy: Enemy" and "Enemy:Anim". If you add an enemy to the hiarchy that also has EnemyPatrol object, you must plug those variables back in or your enemy won't move/attack/idle. Maybe I just missed something, or maybe there's a workaround, but it's not THAT bad. Just good to keep in mind

[@kodysmith2532]

I am trying to figure out how to implement the enemy damage in my code which I have made a few tweaks to to not include player projectiles. I want to handle the damage the same way but just on the mouse click. How would I incorporate that?

[@franciscospinola7883]

Hey, I didn't wanted the range enemy so I didn't change the way how the script Health works. Will this cause problems for me in the next tutorials? (In my case just the audio tutorial and the chekpoints & respawn tutorials).

[@aychar]

Would it not make more sense to make a base Enemy class and then have RangedEnemy and MeleeEnemy inherit from it to prevent copy and pasting your code?

[@asyhhaz]

Thank you for uploading. May i ask when u will upload the game over??

[@PandemoniumGameDev]

This weekend I'm finishing the audio & music episode, then the game over screen is coming next week probably.

[@TheTokoshi]

Great tutorial but I have 1 mistake could you help me? When I kill an enemy he moves far away. What should i do my friend.

hi, great video thanks! i have one problem when i click is trigger my enemy fall down from scene can you help me about that?

[@endersuit8076]

i want to congratulate you for you r good tutorial ,but i have a little issue : enemy fireballs dont go into the right direction , and even by doing what you have done at minute 41:00 it didn't worked and i don't know how to fix , do you know something to help me?

[@gearsbright4599]

14:54 Is it neccesarry to take existing BoxCollider2D and using its properties make damage area. Is it possible to add second BoxCollider2D component just for that purpose or making damage area? Or would it be less optimized to do so?

[@triplea7260]

Thanks a lot❤️

[@user-ye5ud2rw6w]

Hi there! i already follow the tutorial it was great tutorial, keep it up! but I wanna ask about the enemy health can you make the enemy health visible to the player like the player health bar but in the enemy. please make it the video tutorial cause I wanna learn how to do it, thanks a lot before.

[@aeennem3896]

[@patrickkusmajadi4736]

thANKS NOW I KNOW HOW TO MAKE A TIMER sorry for capslock im to lazy to change them

[@anthonylewis3804]

I'm having a problem with my arrowtrap ever since I changed the enemy projectile script every time it hits the player or the wall it stays frozen there and keeps shooting. I think because it's not disabling when it hits anything. Any opinions?

[@user-mw5ud9ug2z]

@PandemoniumGameDev In the unity console it is displaying that the "animator for the melee enemy has been destroyed but you are still trying to access it" Can you suggest a solution to this btw love your tutorials

[@kieranryan7625]

Another dumb question, my ranged enemy works perfectly. Except that when he is patrolling he is moving backwards haha. Like he moves right while facing left. He hits the right edge and turns, then he faces right and moves left. I'm using a different sprite but I'm sure it's something I'm overlooking. Thanks.

[@watchmytvjctechnology8448]

I'm not a game engine guy i prefer coding everything , but i think the problem can be resolved by change flip depending on your sprite , if it is face right by default in left controller set it to true then set it back to false in right controller ,else do the opposite. Here's an example : kzbin.info/www/bejne/jnqopadqfK2Sg9E

[@quinclarke2331]

Hi thank you for the tutorial is amazing and s much help but I have a problem. How do I get the enemy patrol to work for lots of enemies and also two different types I set the enemy patrol as prefab and just duplicated it a lot and moved left and right edge to where I need too. But the enemies sort of bug out when more then one enemy patrol is active they don’t move inside of they’re edges or freeze up at certain points. Wondering if anyone else had this problem and knows a solution thank you!

[@mukundkumar3403]

16:32 Hey, this problem is still there in my game and the melee enemy is not working. Plz help.

[@tomtornados6236]

When the enemy changes direction, the active projectile flips to the other side relative to the enemy. Is there a fix for this?

[@MyMike004]

Not sure if someone still can answer my question but I got an issue when my player gets hit The player is out of the range of the enemy but still get damage. How to fix that issue? I am using a linecast to check if the player is in range

[@doscreditos]

Do you know to make a KnockBack Effect for our player?

[@prodickty]

Thank you for the tutorial. I have a question, I have followed everything that you did in the video to fix the enemy patrol only attacking after stopping. However, mine is still the same, any clue to what might have been the cause? Edit: After reading some comments it turns out I forgot to put the knightenemy under the enemypatrol hierarchy.

[@rounakghosal9727]

had the same issue! thanks for the heads up :D

[@tominolulino9170]

Hello, can I ask why my Enemy dissapears when i turn on the game, he goes somewhere under the ground so I cant see him ?

[@ushas3349]

Hello, in the firetrap episode you said you corrected so that player takes damage when he steps on to the firetrap and sit there idle. But I folled all your corrections. But still player does not receive any damage when he sits on the firetrap continuously without moving! Pl give me some hint to solve this issue.

[@skyherald7390]

the EnemyFireball is not visible when he the enemy shoots but the invisible fireball still hits the player the Sorting layer on the fireballs is set to Foregrounds so idk the problem Please Help someone!

[@skyherald7390]

Someone help as soon as possible

[@malwida1022]

I resolved an issue that bugged me for a long time: whenever the enemy changed direction, all enemy fireballs already in flight suddenly appeared on the other side of the screen, because the Enemy fireball holder changed direction along with the enemy. I couldn't figure out why this is not happening in the tutorial, and why behaviour was different for me. I finally fixed it by disabling the EnemyFireballHolder script (which follows the direction of the enemy) and instead implementing the same logic that is applied to the player fireballs (set direction in the PlayerAttack and Projectile scripts) in the RangedEnemy and EnemyProjectile scripts. Now everything works as expected, maybe this helps others with the same issue.

[@KingDoodies]

Hey i have a problem, when i set my layer to player he free falls through the ground, is there any fix to this?

[@PopcornGoPro]

An easy fix for the firetrap is just to simply change the onTriggerEnter to onTriggerStay =)

[@b7lee948]

i want to ask do you know how can you make character transformation for example like goku from dragon ball love your tutorial btw

[@PandemoniumGameDev]

Yeah, you have a couple options. 1. Change the entire character sprite or 2. Divide the character into a couple images: hair, chest, arms etc and then change the sprite or color on each individual element like Goku's hair turning yellow.

[@b7lee948]

@@PandemoniumGameDev Does change the sprite effects the animation?

[@mirlikiiski9054]

Thank you for the video! I have a question. How to make the enemy turn towards the player when he approaches from the back?

[@AnEmortalKid]

Probably need a ray cast behind the enemy in a box (sort of how the spike head detects in all 4 locations). You could also setup an additional collider on the backside and if you get an enter event, make the enemy turn around.

[@c4rri770]

friend, I have a problem, I did everything right and if I came out with an enemy, but when I create another and put the scripts into it, it doesn't hurt, it can perform all the animations but it doesn't hurt the player and it doesn't give any errors, what could it be??

[@feryadrashad9561]

great tutorial man, but the sprite doesnt stop attacking after the player leaves the hit zone, anybody got some tips?`

[@lordmwmw7576]

The boxcast/playerinsight function returns true no matter what, even if my player is clearly in the box. I saw that you had IsTrigger activated, but doing so makes my enemy clip through the floor. Really confused, need help!!!

[@alfazul21]

why does my fireball only has short range of distance? it dissapear before even collide with anything

[@highmuzik5132]

Help me, I can't see the Collider Parameter in the scene, it seems to be hidden, I can't see to adjust

[@karun7275]

for some reason i get the red box but when the player walks into the range of the enemy the attack animation does not trigger and the player doesnt even get damaged. and i think the root of the problem is the raycast is not detecting the player is there as the animation when the player is in sight to attack is never called.

[@prochysolaire9055]

i have same problem

[@cosfia2167]

I have the same problem ;;

[@cosfia2167]

no idea if this is still relevant, but I had the same problem and its probably not the best way to solve it but I simply put the distance value (5th one) > 0 and that triggered the animation for me RaycastHit2D hit = Physics2D.BoxCast(boxColl.bounds.center + transform.right * range * transform.localScale.x * colliderDistance, new Vector3(boxColl.bounds.size.x * range, boxColl.bounds.size.y, boxColl.bounds.size.z), 0, Vector2.left, *0.2f* , playerLayer);

First of, I want to say that you have a great tutorial! I have been following ur first until this video for my personal project. Unfortunately, I'm having an issue in Ranged Enemy AI. Specifically in 40:08, I could not get to play in Unity, as I encountered an error message "UnassignedReferenceException: The variable anim of enemyPatrol has not been assigned." I also see that in 39:48-39:50 in your video, which mentions how you do not have the enemyPatrol assigned. I tried following your tutorials and even tried restarting your video to see the issue, but haven't figure out how to solve it yet. What seems to be the problem and how can I solve it?

Great Video and great series. I have one small problem that I can't seem to find. On the last part of the video about giving enemy damage, my player seems to treat them like a wall or the ground and he doesn't go through either of the enemies. I can jump on their heads and just stay there and I don't fall through. I don't know if there is some collision connection in the editor that I'm missing or what. Any help or advice would be appreciated!

[@smoothdawg1433]

I also won't take damage if I jump on top of them or anything and I have applied the enemy damage script and set the value to 1

I also noticed that with my ranged enemy he will shoot fireballs but sometimes some of the fireballs just explode right in front of him while others will actually shoot towards me.

I had this problem as well with the player in episode 4 but I can't remember exactly how I fixed it

[@scorpiusjones5436]

It could possibly be because the Ranged Enemy does't have any movement logic attached to it alone, that's in the Enemy Patrol script. It seems like anytime I remove/add a enemy to the scene, I need to plug the info into the Enemy Patrol prefab in the hiarchy to make the enemy patrol
