It's 2021 and THANK YOU for explaining bitmask and the operators clearly and concisely. I got everything that I wanted to learn at 9:00 - 11:00

You are excellent at teaching! You explain basics and behind the scenes so nicely. Keep it up.

trying to search for a collision layers tutorials on RU-vid was pretty frustrating because every video recommended to me was just talking about collisions in general. I am happy i found this one, it's saved me allot of headache :D

Thanks so much for teaching layers a lot easier for me 2:55

Fantastic explanation. Some of your code is a way out of my knowledge base as I'm only a beginner, hobbyist programmer but this explained what I needed to know perfectly. Also you showed implementation by writing out examples; that really helped.

Thank you so much! I was having problems with Raycast (enemy should only look for player's collider but it checked every other collider too) but thanks to your explanation, I managed to get it work with layermask!

Thank you soooo much!! This was exactly what I needed, now I can change collisions from the script thanks to the bitmask!!

Thank you so much for this ... I am studying for the professional programer certification and layermasks with bitwise operators was a subject that i could not understand well from other tutorials. This was very easy to grasp and at last i feel i know how to work with those.

Great tutorial, thank you for continuing to share you knowledge

Concise and with quick demos.

Your examples for bitwise operators were very didactic. Thanks man! :)

This is exactly what I needed! Thank you Code Monkey!

please continue making such amazing content

This just saved me A LOT of time. Thank you!

🤯🤯🤯🤯 Awesome as always! Thank you so mutch for sharing!!

Again, thank you for this tutorial! Your videos are well explained and really helpful!

Layer masks might be easy to work with in regards to ray casts but I just spent the better part of a day trying to get one to work in a simple if statement. I wanted to check if an object was on one of a few layers that were selected in the Layer Mask drop-down menu in the inspector.

Crystal clear explanation. Thanks!

I love you so much code monkey, this video really helped, I was at the verge of giving up

Awesome video as always

Awesome detail! Thank you :)

Exciting and very informative video. The sound was good at home. Only downside: your little ads at the bottom of the screen annoy me (a little) to read the subtitles. But I will come back :)

This helped me. Thank you!

I saw you on Brackeys insta story❤️. By the way it's too late to comment😅

Very good video on layermasks.

What a great tutorial Thank you!

thank you, this was very helpful!

Awesome. Thank you!

Best tutorial ever!!!

You are the best at what you do.

luv your content bro

Sweet! I diddnt know you can stop certain layers from interacting!!! Now i can make it so my player can walk throw the ragdoll corpses of other enemies!!!!!

Informative☺️

Sweet, I didn't know LayerMask had its own custom editor in SerializedFields. Personally I usually have static classes with constants and one of such class holds names of all layers, so I can do LayerMask.NameToLayer(Consts.LayerNames.Debris) somewhere in Awake(). It just feels very nice when IDE autocompletes layer name for you. (I don't like that it deals with strings, but sometimes man gotta forgive himself)

I love you!

Awesome..THank you :D

great tutorial thanks...

Thank you!!

I didn’t knew that I could use the layer mask to shoot like this but can we use the layer mask to make enemies following me but not going on environnement?

Great tutorial!! Can you please make a series on how everything in Unity2D template project (platformer) works.

Excellent video. What's the use of using the binary method if the enum for LayerMask is visible outside? Also isn't it more readable and user friendly if one were to use GetLayerMask("Name") ?

Thank you

you. are. a. GOD!!! :D

6:50 How is the layer mask ignoring the debris without any code? All you did was declare a layer mask variable. Is there nothing we need to do with the raycast function?

So I can just set some static integers to use everywhere when I need to get certain layers? Like one mask for everything walkable, one for everything attackable by the player, one for attackable and walkable, and so on.

How can I set up an ignore layer mask?! I want to check for ground against all collides except the ones with the ignore layer . I know that I can check for ground against all the colliders with (the ground layer for example) I just need this specific behaviour .

If I understand correctly, I can use layers to keep Colliders I use as triggers from interacting from each other, correct?

is it possible to add an extra layer between 2 layers? maybe move them?

Hi code monkey i would like to know how to change base layer weight to 0 and thank you

I dont know if id have ever gotten this if I didnt see your visual demonstration of the debug og representing the layers.

Is there a noticeable performance difference between LayerMask and Bitshift when doing expensive operations like raycasting in Update()? Thanks a ton for the vid. I came here to better understand Bitshift, and you definitely made it easy to grasp.

God, [SerializeField] private LayerMask groundLayerMask; won't bring up the layermask option for me in the editor and I can't figure out why

The tutorial is amazing, thanks for sharing! I never understood Bitmask because i was too scared, as everybody said it involves lots of calculations, and you explained in such and easy way that now i feel like i got it! Also, could you give me an insight about some code? To contextualize: First, i detect with a collider trigger the reacheable area, then if there is something with the tag "solid" in the way, i shoot a Raycast. if the Raycast hits a Rollable layered object, then i set a animation bool to on, to enable a pushing animation. The problem is that it simply does not work. It's always "NO ROLL". The object is marked correctly, and the layermask is too, and the debug show it works as no roll when hitting any surface, including the one i'm trying to get. Also, it don't display any error. private void OnTriggerStay(Collider other) { if (other.CompareTag("Solid")) { Player_Animator.SetBool("FrontDetected", true); Physics.Raycast(transform.position, transform.forward, out HitFront, maxDistance); Debug.DrawRay(transform.position, transform.forward * maxDistance, Color.red); if (HitFront.transform != null && HitFront.transform.gameObject.layer == Rollable) { Player_Animator.SetBool("Roll", true); Debug.Log("Roll"); } if (HitFront.transform != null && HitFront.transform.gameObject.layer != Rollable) { Player_Animator.SetBool("Roll", false); Debug.Log("NO ROLL"); } }}

Is there a reason why you can't just refer to the Layers via a simple int? The Bitmasking is cook, but it seems overly complicated.... But I don't really know what I am talking about :D

Can you make tutorial with godot engine?

you didnt show writing layermask in the raycast

how to make left, right and jump buttons for android device

hello

So few subs

first

You need to buy a better microphone or increase the volume of your videos...

What's the actual difference between Physics.Raycast() and PhysicsRaycaster.Raycast()?

I love you!

I love you!

I love you!

I love you!
