this was the only versatile way of doing it in 2D that I found thank you so much man

Great tutorial! I'm making a platformer style game where I rotate my enemies around the Y axis 180 degrees (rather than the Z axis), so I made the following adjustments to the code in case it will help anyone else: // To check if the target is within the defined angle - Edit line 42 at 16:46 if (Vector2.Angle(transform.rotation.y == 180 ? -transform.right : transform.right, directionToTarget) // To draw the angles - Edit lines 63 and 64 at 16:46 Vector3 angle01 = DirectionFromAngle(-angle / 2); Vector3 angle02 = DirectionFromAngle(angle / 2); // To get direction from angle - Edit lines 77 to 82 at 16:46 private Vector2 DirectionFromAngle(float angleInDegrees) { return (Vector2)(Quaternion.Euler(0, 0, angleInDegrees) * (transform.rotation.y == 180 ? -transform.right : transform.right)); }

A quick tip. It’s much more optimized to multiply by 0.5 than divide by 2. It will make a difference if you have 10s of thousand of entities.

I watched your 3D video first and attempted to convert it into a 2D one. Thank you for giving videos on both!

Haven't seen from your channel in a while... It's as awesome as I last remember it

Good tutorial. I implemented this and had an issue with the gizmo. I noted a couple of issues that prevent the gizmo from properly tracking the transform as it is rotated. at 16:48, On line 63, remove the - sign in front of "transform.eularAngles.z". this angle is absolute z rotation of the transform and does not need to be negated. Also on line 79, you use "angleInDegrees += eularY". It should be -=. z rotation in the clockwise direction is actually negative. Make these two corrections, and the FOV Gizmo properly tracks the transform's z rotation.

Keep Up The Good Work!

Thank you so much ❤ This is exactly what i was looking for ❤ ❤ ❤

thank you so much you saved my life with this vid

Cheers, excellent tutorial! Definitely subbing for more

Exactly what I needed great tutorial fr a beginner like me, even helped me solve a problem with another script of my own thanks to what I learnt from this

THX A LOT DUDE u helped me a lot, u have noooo ideia, just thx bro

Great tutorial :)

Thanks 4 tutorial! It very usefull

Thanks you, the script is working well!

You are great 😊

I made the mistake of starting a function/void within the - if (CanSeePlayer) - of the OnDrawGizmos void instead of the FOV void. The void is called upon as wanted when testing in Unity, but not in a build (I've only made a WebGL build so maybe Gizmos particularly don't work in that framework?) If anyone else made the same mistake and doesn't understand why it's not working, now you know how to fix it 😋 And thank you very much for this tutorial, I was trying to make other methods work that aren't even eligible for what I needed and your solution just works perfectly!

"return new Vector2(Mathf.Sin(angleInDegrees * Mathf.Deg2Rad ), Mathf.Cos(angleInDegrees * Mathf.Deg2Rad))". Essentially, this is using the Pythagorean theorem to complete the square. Sin is used on the X axis, and cosin is used on the y axis. this provides a tangent that gives us our right angles to solve for the angle of the triangle formed by x and y on the surface of a circle. MathF.Sin and Cos require radians, so the angle is multiplied by Pi/180 (Mathf.deg2Rad) . Anyone please correct me if I got any part of that wrong.

15:00 Lmaooo; also, thanks for the video

Might have ask before I bought a unity asset of first person arms with weapons and animation also bought a few maps do you have any videos on how to use what I bought to setup first and third person multi player game set up?

hello! I ran into a problem which when I hit play the player ref is automatically set to none again, I don't know why

Hi there, thank you so much for this, it’s helped out a ton and it’s better than all the other tutorials out there! Quick question, how do we go about rotating the the arc around the centre of the object? For example, the arc is currently set north, how would I set it to look east when the enemy is looking east? Thanks in advance!

I commented with a fix that deals with that issue. look for my comment. The FOV code works as intended. The Gizmo does not properly represent what is happening with the FOV.

Edit the first parameter of Vector2.Angle at 16:46 on line 42 to whatever you want. For up: transform.up For down: -transform.up For right: transform.right For left: -transform.left To reflect this change on the gizmos drawn, see my comment and replace the transform.right with whatever you're using.

does anyone know how to make the FOV rotate with the attached gameobject as it rotates too? (e.g. enemy rotates to look at player and the FOV follows) Because right now my sprite rotates to look at the player but the FOV (yellow lines) always at a 90degree angle to the left of the sprite no matter what.

anyone know how to visualize the field of view in game instead of the inspector?

Bro, how to make a set of enemies coming in a straight line or forming sine wave or in a circle formation like space shooter games.

I love the accent.

Nice Tutorial. How may I rotate the cone of view?

I posted a comment to correct the gizmo, so it properly tracks the rotation of the transform. Check that out.

I have the same question that SM[BJS] has!

Can you detect if the mouse position is in the field of view?

I believe that if your pointer is a GameObject with a collider and on the right Layer, it should, yes.

Wow. You've improved on the earlier video in three very important ways. (1) Correct pronunciation of Euler 😀 (2) Use of OnDrawGizmos (so much easier than an Editor script) (3) You're using a Mac. You've clearly taken the red pill. Welcome to the light!
