Thank you so much. I wish every tutorial on TH-cam had such methodical and thorough explanation.
To keep track of enemies: I used to call an event which fired when an enemy died, and the counter in another class looked at that event, to keep track. Your way is more elegant and more organized. Thanks a million, for showing us.

This tutorial works awesome, thanks for the tutorial!!!!

[@satyrn6118]

Thanks. This helped a lot adding a health system

[@codecodile]

Glad it helped! :D

[@docgraal485]

@@codecodile i am making an fps and I have used different tutorials for help, I cannot find a good tutorial which gives a health system for the player where they would decrease health as they collided with the enemy projectile and for it to be displayed in a text mesh pro ui feature, please can you make a video explaining this because I love how helpful this was. My assignment is due on Thursday this week, no rush but help would be appreciated

im getting this error:
NullReferenceException: Object reference not set to an instance of an object
Enemy.Update () (at Assets/Enemy.cs:24)

[@destijl1337]

Hi, thanks very much for this. I used the array code you provided but my enemies vanish quickly after appearing each wave. Can you point me in the vague direction of what would be causing enemies to be destroyed quickly after they're first instantiated? I have a feeling it's to do with the values I'm inputting into the inspector but I'm not entirely sure - it seems that the waves are ending suddenly then moving onto the next

[@TheDemoncrater]

¨Sorry but which script do you want the start function? at 5:14?

[@evyman7515]

Does anyone know a way I could spawn power ups along with the enemies each round but still only killing the enemies progresses the rounds?

[@blanketdev7911]

hi it says that the index was outside the bounds of the array for each code where I had currentWaveIndex do you know a fix for this problem?

[@codecodile]

I do not know exactly what the problem is because I do not have the code. Maybe check again if the code you wrote is exactly the same as in the video :)

[@perdoist3627]

Basicly even when the last wave is over it still increases the current wave. So you have to stop the increment after the last wave.

[@docgraal485]

How do I add a textmesh pro ui feature where it displays the wave number at the begining of each wave?

[@codecodile]

First create the UI in the editor. Then just set the text of this to the currentWaveIndex in the Update function.
Then you write some code before you spawn the enemies. Just activate the text object, wait an amount of seconds(I recommend using Coroutines, but you can also just create a simple timer for that) and then disable it again :)

hi, kannst du mir helfen bei mir wir das ihn der console ausgeführt

[@spinospine]

Thanks for the video ❤how do i adjust the scripts so that the waves are infinite and that there's the same wave of enemies each time?

[@Sinbad1999]

i followed the tutorial but when i press play and the countdown goes down to 0, an infinite amount of enemies spawn in and lags the entire project. Any way i can fix this?

[@nuclear270]

me too

[@fr3sh80y8]

My code is the same, but all enemies spawn at once :(

[@TheAntox007]

Yeah for me the problem is that It does not see the list at all, like it will spawn the first element from the first array and say that the level is finished, I am currently Debugging to see where the problem is

[@kentanggaming0386]

can share your code ? pls

[@TheAntox007]

@@kentanggaming0386 i made workaround where I set 5 waves with firat empty then 3 of them work, and the last is empty so the code for finishing activates whrn the last wave spawnes but is empty

[@yasuomain5942]

@TheAntox007 Use {System.Serializalbe} to show it in the Inspector

[@ARIEL-xf8gg]

mine is doesn't generate the other wave's, the output just the first wave, can u give any advice?
so my program doesn't increase following the currentWaveIndex, idk why thoo.. i have following all in this video

[@codecodile]

I do not understand your problem completely. Could you be a little bit more specific what exactly isn't working?

[@chaz4949]

trying to add it to another health script the part with the countdown, but it wont let me put the "waveSpawner.waves[waveSpawner.curentWaveIndex].enemiesLeft==;" part in as it says that ; is an invalid term

[@Robert-rh8dh]

Hey enyone know how to fix a glitch where if two projectiles kill the same target at the same time it counts as 2 kills messing up the whole enemiesLeft counter

[@elicentric]

i have the same problem but im not using projectiles

[@sketchturner8229]

Hello! Thanks for the tutorial.
I Cant understand whats wrong, all made like you. (Im new in scripting :))
UnassignedReferenceException: The variable spawnPoint of WaveSpawner has not been assigned.
You probably need to assign the spawnPoint variable of the WaveSpawner script in the inspector.
WaveSpawner+d__6.MoveNext () (at Assets/Scripts/Enemy/WaveSpawner.cs:41)
UnityEngine.SetupCoroutine.InvokeMoveNext (System.Collections.IEnumerator enumerator, System.IntPtr returnValueAddress) (at :0)
UnityEngine.MonoBehaviour:StartCoroutine(IEnumerator)
WaveSpawner:Update() (at Assets/Scripts/Enemy/WaveSpawner.cs:33)

[@chellminn]

I had the same problem. In order to fix it, click your Wavespawner in the Hierarchy. If you then look in the Inspector you'll see beneath Countdown a line with Spawn Point and None (Game Object). From the Hierarchy drag your Spawnpoint in here. If I'm not mistaken that should fix the problem.

Thanks for the comment, it can help others))
