For everyone who's getting UnassignedReferenceException when your fireballs hit something change this part of the code:
to this:
The ? will check if the object has a Health component before trying to damage it.

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 :(

[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!

18:42 little optimization quirk

Putting in "if(hit.collider != null)" inside the "PlayerInSight()" method to see if it needs to get the health component of the player means it's doing this check every single frame. Plus, it re-assigns "playerHealth" with the same value every frame the player is in range. But the method already returns the result of "hit.collider != null" at the end. The DamagePlayer() method already checks "if(PlayerInSight())" to execute "TakeDamage()", so it's basically doing the same check twice.

You can just declare the "Raycasthit2D hit" variable as private outside of the method, which means DamagePlayer() will have access to it when it's called. You end up not needing the "playerHealth" variable. So it can just be:

private void DamagePlayer()
{
if(PlayerInSight())

}

The only way PlayerInSight() will return true (and therefore run the next line) is if the "hit" variable currently contains the player object it has collided with in the check. Had no issues trying it this way. Saved a single glorious check per frame. Mom would be proud.

Greatest Tutorial With All Details Ever Seen Here in my 1.5 year of learning started from WebDev to Get Understanding of Programing then Android App Development and finally half year ago started unity and that is were i want to stop Shout Out To this Man He is Incredible

[waltersattazahn]

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.

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

[RMCMiner]

Ive been waiting for so long, so happy the new one is out!

[PokimBarran]

Thank you so much I have been stuck on this for days. Really helped thanks.

[balab]

i will not give up and finish this series !!!

[cmemfrx]

Finally! Thanks so much! Your tutorials are really helpful and well organized.

[scorpiusjones]

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

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.

[Majitsu_san]

I still have a problem when melee enemy patroling the points he doesn't stop to hit me. He goes to the end of the edge and only than makes a hit///

[ushas]

Thank you so much for the wonderful unity 2D platformer series. I enjoy creating the games along with you. Usha

[prochysolaire]

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

[patrickkusmajadi]

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

[malwida]

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.

MissingReferenceException: The object of type 'Animator' has been destroyed but you are still trying to access it.
Your script should either check if it is null or you should not destroy the object.

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.
