In the next episode we'll add a main menu, a game over screen and other UI stuff. Thanks to everyone for the patience!

[@SSMLivingPictures]

Its worth the wait!

[@PandemoniumGameDev]

@@SSMLivingPictures Glad you feel that way, because the wait is LOOOONG 😂

[@SSMLivingPictures]

@@PandemoniumGameDev 😅👍 All good. It takes me a long time to put what Ive learned into action.

[@ubershoku4563]

thank you for making a very good guide and tutorial. i found your video are very helpful and help me to understand on how unity and how the C# syntax are coded. As a beginners i would like copy and learn on the parts and maybe adjust it for better understanding which is why i really love your video about it.

[@Chitose_]

does this include a levels system? i hope that gets added

[@YourGameDevTutor]

Honestly probably the best tutorial playlist for 2d unity on KZbin

[@jerryrogers8679]

This is a great series! Thank you for doing this!

[@jnilsson89]

Thank you very much for these Unity tutorials, they've been excellent so far.

[@itsalwaysunny]

thanks for your hugh help, you don't even know how much your tutorials helped me in my college projects, thank you soo much once again. keep respawning ;-)

[@Gokun1102]

oh gosh ! I was looking forward to your videos so much! Thank you so much for your guidance

[@tommasoraimondi6908]

Great man, those tutorials are getting better and better!

[@PandemoniumGameDev]

Music to my ears, thanks 😀

[@boyshader489]

[@blach1526]

Dude, that's awesome, just what every beginner needs. Fucking legend you are!

[@paroxysm4566]

the man is back again! good to see you uploading bro

[@BillSoutherland]

Great tutorial series, thank you for the time and effort. I did notice one little problem and you actually display it in your video: when the player dies and is transported to the last checkpoint, the obstacles (that's what I call them) in that room do not appear - though they will reappear if you move to the next room and then move back.

[@severin9801]

youre the best, keep going !

[@jasonnjoroge7947]

This is the best tutorials ever in 2D

[@PandemoniumGameDev]

[@turtlegod1013]

During the end result, when you respawned, the arrow trap in the first room didn't activate. How would you fix that issue?

[@manuelestebanpadilla1225]

YOOOOO just now I needed how to respawn the player when he dies, thanks :D

[@PandemoniumGameDev]

I knew it :D Glad to help!

[@iiv13tkd92]

I love the tutorial, it is really helping me and is there any way where the game can be timed, with the player performance based on the score achieved over a certain time

[@cleangaminganalysis8651]

lets go new video

[@kieranryan7625]

Hey! Thank you so much for this series, it's been a blast so far and feel like I've learned so much. I'm currently trying to make the camera shift up or down to a upper/lower room when the player goes through the door but can't seem to make the code work haha. I have a copy of the door just at ceiling level. Any help would be appreciated, Thanks!

[@mfspawn1474]

Thank you so much for these videos, been following the whole way and am finally caught up to date. Everything works perfectly, altough if you spam space while you die you get stuck in an invulnerable state and are still able to move but not attack or actually die. I followed the previous videos exactly and it even respawns if you die in mid air. But if you spam space you don't respawn and are invulnerable. Did I mess something up or does this happen to you also @Pandemonium? Again thank you so much and sorry for the wall of text.

[@noisepipa]

same happens with me

[@arkhamknight3335]

You rock bro

[@trunghieuthai9472]

Why can't I move when I return to the checkpoint when I die?

[@al4965]

Great video, simple explanation that make things more clearly and easy! but do you know how to make a finish line that will go to another scene?

[@PandemoniumGameDev]

At the end of episode 11 we loaded the second level, so you can just use the same logic only apply it to a new object when it collides with the player.

[@kechrimpari2348]

In which tutorial is the components heading added along with it's code? I've searched through the tutorial but haven't been able to find it

[@MiyamotoMusashi209]

HI, whenever i try to play my character sometimes falls over of does loads of flips, what could i do to fix this?

[@maksimuz3640]

Will you make change weapons (sword/gun for example ) and new types of enemies flying etc.

[@PandemoniumGameDev]

Sorry but nope, I'll make a menu system, a couple levels and a boss and that's it for this series.

[@YourGameDevTutor]

Hi mate, ever since episode 7 my character falls through the ground when taking damage from an enemy. Does anyone have any idea why this could happen?

[@zoks]

If the player does not pick up any checkpoint and dies, they will be respawned at the location they died at, which is probably not what you want. Should set an invisible checkpoint at the start of the level, right at the player's starting location, and disable sprite renderer on that individual checkpoint.

[@snowsetdeer6192]

First I'm really glad you pointed this out, my checkpoint was in the first room so I probably wouldn't have ever noticed that this happens. I tried to just make a checkpoint without the sprite renderer, and it was indeed an invisible checkpoint on top of where the player spawns in, but it still made the "getting a checkpoint" sound. To fix this I made another prefab called "spawnpoint" by just dragging and then renaming a checkpoint into the prefabs collectibles folder, and added a new tag called Spawnpoint. Then I went into the PlayerRespawn code and copy pasted these 3 lines of code(without the sound line!) into a new if statement inside the OnTrigger2DEnter method, but checked for the spawnpoint tag instead of the checkpoint tag. My OnTriggerEnter2D method now looks like thise: //activate checkpoints private void OnTriggerEnter2D(Collider2D collision) { //fixes issue where if player had no checkpoint, they respawn exactly where they die. In the hierarchy, the sprite renderer //is turned off, and this is the same as a normal checkpoint just with the sound disabled. It reads the tag to make sure its the correct thing if(collision.transform.tag=="Spawnpoint") { currentCheckpoint = collision.transform; //sets first spawnpoint for the player before any checkpoints //SoundManager.instance.PlaySound(checkpointSound); //mutes "get checkpoint" sound collision.GetComponent().enabled = false; //makes it so you can't reactivate the same checkpoint over and over collision.GetComponent().SetTrigger("appear"); //triggers appear checkpoint animation (could probably comment out too) } if(collision.transform.tag=="Checkpoint") { currentCheckpoint = collision.transform; //store checkpoint that we activated as current checkpoint SoundManager.instance.PlaySound(checkpointSound); collision.GetComponent().enabled = false; //makes it so you can't reactivate the same checkpoint over and over collision.GetComponent().SetTrigger("appear"); //triggers appear checkpoint animation } } I hope this helps someone else!

[@fudzicrew1615]

best tutorial

[@bazej616]

maybe in the future make tutorial for boss fight or how to make customs units for some begginers :D

[@maxrobloxgaming9043]

I have a problem where when I died and spawn back and died again I didnt respawn back and play the "Die" animation

[@AnEmortalKid]

If we are using the follow camera we don't need to reset the camera after respawn correct, since the next update frame on that camera will move to where the player has been respawned to (I much more like the follow player cam instead of room based cam). I didn't notice any visual difference when not moving the camera, but I was wondering if perhaps there's something about moving it besides just focusing on the correct thing.

[@AveryCruz-se5ky]

What would be the code for the camera if I'm using the follow player camera?

[@AnEmortalKid]

@@AveryCruz-se5ky it’s been a year so I don’t exactly remember if he talks about it in other videos but The camera controller should get a reference to the player In an update method, set the cameras position to the players position.

[@AnEmortalKid]

@@AveryCruz-se5ky also look at episode 6 in the series. That’s where the first follow camera occurs.

[@gluharone]

Сan you implement shooting 45° up, 45° down, shooting down while jumping, and shooting up?

[@ldmdesign5610]

Would love a tutorial on a swinging rope ;)

[@ushas3349]

I am unable to solve the following issue! If I call respawn after the deactivate funtion by adding event, the respawn does not happen! If I call respawn one time frame before deactivate event at the die animation sequence it works. I tried including gameObject.Setactive(true) in respawn function. Then also it does not respawn!! I wondwr what could be the problem! Any suggestion / hint please. Thank you for the wonderful series. Usha

[@ushas3349]

I think once the gameobject is deactivated, its not possible to activate the same as no method attached to it is available. So instead of deactivating the game object I disabled the sprite rendter component and enabled on spawn player fn. It works. Hope my understanding is correct. Thanks Usha

[@bernardogamula947]

heyy! I need help... when I kill the enemies or get the hearts and then I die and go back to the cheackpoint, these objects don't appear again can someone help them to appear again

[@EliteSchokokeks]

Hey, I came across a Problem, maybe someone can help me. As you can see in the Video at 13:35 the Arrowtrap is shooting downwards, if i rotate my Arrowtrap it does not, i dont see arrows and i dont get damaged

Nevermind...my Arrows had the wrong sorting layer thats all...

[@adriankirita9013]

My checkpoint animation doesn't play, only the sound, do you know what might be the problem? I also get the error message "Parameter "activate" does not exist." when I trigger the checkpoint.

[@adriankirita9013]

Found the problem, in the code the trigger was "activate" instead of "appear"

[@PandemoniumGameDev]

@@adriankirita9013 Yeah the trigger names can be an issue if you don't get them right.

Hi I have finished upto 13. But in respawn player , there is a small issue i am facing. If I create an event after deactivate event (1s) and assain respawn it does not work. If I call the event 1 time frame before deactivate, it works. Its bugging me. Can anyone tell me why? Thanks usha

I have a problem, for some reason the character only revives 1 time and then doesn't die, the damage animations don't appear after he respawns either, any suggestions?

[@PandemoniumGameDev]

Sounds like you didn't add dead= false; in the Health script, in the Respawn method (7:54). If that's not the case check if you have any errors in the console.

[@inhhuuiem6230]

i watched from lesson 1, but i have a problem with this, player dies without checkpoint but still respawns. Do you have any suggestions?

[@PandemoniumGameDev]

Yeah, currently the system will respawn the player even if you don't have a checkpoint. An easy fix would be to put a checkpoint right at the start of the game, although it's not a proper solution. I'll work on that in the next episode.

[@Max-mb2zp]

How do you make sure that the game can be played on the iPad?

[@PandemoniumGameDev]

First you'll need to take care of the controls, I recommend adding some buttons that handle the Horizontal Input because you don't have a keyboard there, also a button for jumping and another one for shooting. Second make sure that the UI is scaleable. Thirdly switch the project to iOS inside Unity and see if you need to adjust the camera size. That's it really, might not be 100% straightforward but should be entirely doable.

Ok, thanks!

@@babayaga6247 That should've been fixed when we reenabled all the components. What you did works too, but you're doubling what already should've been working. Check if you added the Movement to the Components array in the Player's Health script in the editor.

iam facing a bug when the player got respawned once it is not respawning again just beling like invincible going on with zero health and no damage is getting for hero

[@jeevansai6835]

the mistake is in Respawn() in health.cs ,when the respawn happens the value of dead(boolean) is in the state of true soo that the dead animation is not activated and the player became invincible check this out i think i fixed it public void Respawn() { AddHealth(startingHealth); anim.ResetTrigger("die"); anim.Play("idle"); StartCoroutine(Invunerability()); dead = false; //to set the state of the hero is not dead //Activate all attached component classes foreach (Behaviour component in components) component.enabled = true; }
