Quick question: why not use raycasts? You can just skip the maths with that.

[@CodeMonkeyUnity]

@@klarnorbert I do use Raycasts to detect hits, not sure what you mean by "skip the maths", you need to first calculate the direction so you can use a raycast.

[@klarnorbert]

@@CodeMonkeyUnity I mean, using raycast to detect the mouse position in the game area, and then tranfsform.LookAt() that position.

[@charliegaming766]

if you are having a issue of not pointing your aim properly and aim away when you get closer to the player & you are using cinemachine victual camera to follow the player, just remove the camera controller script from the player if you are using one to follow the main camera behind the player. it will fix the issue. it fixed mine. hope this helps.

You can just do: Vector3 aimDirection = mousePosition - transform.position aimTransform.right = aimDirection Less code and more performant

Hmm interesting, I've never seen anyone modify the transform.right directly, not sure if that works the same or bypasses anything. Knowing how to do math with angles is still helpful though, it's used to fire the weapon shell.

Great video, one question though: At 13:30 you add the code to flip the gun depending on the angle, but I dont see how you are getting the whole player to point in that direction as surely that is handled in an animator elsewhere? Are you just adding a trigger to your main player animator to change on pointer angle?

After finishing with a D in the Jr Programmer path I am more demotivated than ever. 2D game but you are still writing vector3. No idea why. When I add this to my prototype my weapon is ordering around me. Instantiate(puke.prefab bla puke.prefab.rotation). And they say UE5 is even harder. Is it in chinese or something?

[@CodeMonkeyUnity]

Because at its core Unity is a 3D engine, you can use Vector2s if you want, they will just automatically be converted into Vector3. It sounds like you should focus on the absolute basics first, check out my free beginner courses kzbin.info/www/bejne/d56qhHh-bLaWesk kzbin.info/www/bejne/poPIg2mQbtd-Y9E

Like no matter how much you learn, its never enough. Frustrating.

[@CodeMonkeyUnity]

Programming is a relatively complex skill so yes what you are describing is the perfectly natural learning process. It takes time to learn, that's normal. I've been programming for 25 years and I'm still learning new things

[@ClaytonWasTaken]

If anyone is also using a script that updates the Camera's position in LateUpdate, you will notice that the aiming stops working correctly the further you move away from your player's starting position. A simple fix that I found was moving HandleAiming(); into a LateUpdate instead of Update. You should keep HandleShooting(); in a regular Update as it uses Input.

How can I make it so that I have a crosshair that rotates at a certain distance from the player to the mouse but does not rotate itself?

Since you know the direction vector from the player towards the mouse, you can just manually position it through code, instead of making it a child game object visual crosshairTransform.position = playerPosition + dirToMouse * distanceOffset;

this may be a bad question. I am just wondering if it is at all possible to have something like this switch between mouse and the right stick of a gamepad. Using the mouse the gun follows the cursor but with game bad the gun will go in the direction of the right stick. Is it possible to do something along the lines of moving between these two control schemes?

[@CodeMonkeyUnity]

Sure, you can listen to either mouse input or gamepad input and set the latest one as the active one. I did something like that in my Virtual Cursor video kzbin.info/www/bejne/oGO7qq2JdqlnjLc

how do you make your player change directions without the pistol sprite also moving in that direction?

[@CodeMonkeyUnity]

Depends on how you are handling the player changing directions, sounds like maybe you are inverting the localScale.x? If so one solution is to not make the weapon a child of the player, make it a separate object and just make it follow the player position

[@caiquemoa]

the part that i was most interested you just skiped as "quick polishing" did you teach it in other video or are you saving for your course? if yes which one

[@CodeMonkeyUnity]

What part? The Screenshake? That depends on how you set up the camera, in this case I had a normal camera so I just move it randomly for a few frames, if you have Cinemachine you add some noise. The shoot flash? It just spawns a sprite for the flash and destroys it after 1 or 2 frames. The bullet trace?

Aiming works fine as I can see from the debug.log of the angle I'm aiming at correctly. The "object reference not set to an instance of an object" error triggers within HandleShooting() on this line: OnShoot?.Invoke(this, new OnShootEventArgs Visual studio is not flagging any issues.

The projectile is an empty game object (shell) w the projectile script attached, and a child visual which is simply a square sprite scaled into a rectangle (aka my placeholder laser visual). Then I have the Aim empty gameobject as a child of the Player (shell) with a child game object for the sprite and another child empty gameobject for the GunEndPointPosition.

Stretch? It should be rotating on the correct axis, should not "stretch" or deform in any way, maybe you're rotating on the wrong axis? Or you're just using pixel art and talking about pixels being off, if you use no anti aliasing then yes some angles will look off in a perfect pixel art game. For that the only solution is to not use this system and draw some specific rotation sprites and swap sprites instead of rotating the game object.

When I switch the code to Vector3 mousePosition = Camera.main.ViewportToScreenPoint(Input.mousePosition); it works but in a strange way, where moving the mouse rotates the character but it doesn't point at the mouse position. My full code is: Vector3 mousePosition = Camera.main.ViewportToScreenPoint(Input.mousePosition); Vector3 dir = (mousePosition - transform.position).normalized; dir.z = 0; float angle = Mathf.Atan2(dir.y, dir.x) * Mathf.Rad2Deg; transform.eulerAngles = new Vector3(0, 0, angle);

[@TheCeglaaa]

Ok, I managed to handle it. If anyone has a problem, here's what was wrong - you need get the position from the camera's point of view on the player as well (dunno why tho). This is how you should calculate dir for it to work Vector3 dir = (mousePosition - Camera.main.WorldToViewportPoint(transform.position)).normalized;

Thanks for the awesome content. I'll make a small shooter, nothing more than some squares shooting at each other to begin... I have a simple question: In my C# scripts i can't make one class "find" other classes or scripts. Let's say i am editing the script "MainScript", and then i add a line like this "SecondScript.Functionxxxxx", when you do that, your code has the autofills for the functions or events. Like in this tutorial, the "subscribe to the event" part, mine wont be highlighted in blue and wont have those autofills. That happens with the "EventHandler", "Vector3", "Input", etc. The thing is that they work fine, but it seems my Visual Studio don't know them. (I instaled it after Unity from MS website and did the "Create Unity games" instalation). Sorry for the ̶s̶i̶m̶p̶l̶e̶ big question. :P

[@CodeMonkeyUnity]

Does your visual studio recognize Unity classes? Like Debug and Vector3? Try manually installing the Unity Tools for VS docs.microsoft.com/en-us/visualstudio/cross-platform/visual-studio-tools-for-unity?view=vs-2019

[@Mikael._]

​@@CodeMonkeyUnity Thanks for the help, it was not recognizing "Vector3, Debug, [SerializeField], other classes (project ones or even UtilsClass.xxxx), Vector2, etc..." It recognizes only core C#, like the functions, Int, bool, float, etc. I looked into the link you sent and it was the instalation i did before. (i instaled Unity w/ VS, then instaled it from MS when i started snake tutorial), so if my instalation was right (into work loads it was Unity Development)... there was something in between VS and unity I saw in a forum answer the guy said to enable VS Comunity in Unity preferences as the default C# tool, mine was auto. It works now, just select VS Comunity in Edit>Preferences>External tools And check the "Editor Attaching" box. Then open your scripts from your Scripts folder in unity and now VS recognize everything. Save them all into a single project and all should work fine. I'll leave it here in case anyone have the same problem...

Mikael yes, I have that problem, are you on PC? If you are, that is the PC version, not a bug

Hi! Nice tutorial mate! Can you make an special about mobile controllers? Thanks!

[@CodeMonkeyUnity]

Like 3rd party gamepads? Those are very difficult since they're all different, you're probably better off using an asset that already has a lot of them implemented like Rewired.

hey man, i have a question, it gives me an "Object reference not set to an instance of an object" error in unity, at the line with aimTransform.eulerAngles = new Vector3(0, 0, angle); . Do you happen to know why?

[@CodeMonkeyUnity]

That means you have a null reference, meaning a reference that hasn't been assigned to anything In that line the only thing that can be null is aimTransform, so you probably didn't name the child exactly teh same name as you used in Find(); Whenever you have that error always use Debug.Log to find out what is null unitycodemonkey.com/video.php?v=5irv30-bTJw

[@sanspseudofix8814]

Hello thanks for this tuto But i want to know how to do that this netcode I tried but the weapon dont follow the player

[@CodeMonkeyUnity]

You just need to synchronize a vector3 for where each player is aiming

[@roglSimpson]

Have you had any issues with weapon rotation stuttering or being jerky as the mouse pointer gets closer to the character (it works just fine when mouse pointer is further away)? If so, what was the secret sauce to resolve it? Thanks in advance!

[@CodeMonkeyUnity]

One way you can solve it is smooth out the rotation, perhaps with a maximum speed. Although that would also make your game less responsive so it really depends on your design

[@roglSimpson]

Thanks for the reply! In the end, it turned out I was using the wrong pivot point. I tried calculating the rotation using the weapon's fire point game object, instead of using the arm shoulder as a pivot point and offsetting by Y coordinate of the fire point.

[@namangupta4033]

Hey, I don't know for some reason there's a time lag between clicking the mouse button and the playing of the animation. Very small, like a 0.3 sec time lag, but it's there. What should I do about it ?

[@tarkozkan6439]

you can change sensivity for Inputs in project settings it should do the trick

[@sundarakrishnann8242]

I guess you have to uncheck has exit time in animation transition...

How do I import the Weapon Aim file into unity?

[@CodeMonkeyUnity]

It's a .unitypackage so just drag and drop on your unity project window

Hey, is there any way to hide the mouse pointer AND have the rotation work simultaneously?

[@CodeMonkeyUnity]

Sure, changing the Cursor.visible does not impact Input.mousePosition

And also im getting the error (The script is called Pivot): UnassignedReferenceException: The variable aimTransform of Pivot has not been assigned. You probably need to assign the aimTransform variable of the Pivot script in the inspector.

[@CodeMonkeyUnity]

Check the scale of the parent of the object you're rotating, it should be 1,1,1

[@xiaoyou9412]

Mr.Code Monkey, I am following you video "Aim at mouse in Unity" doing game and here is a problem:when I finished joining the gunflash into the sprite Aim, the animation did but the flash animation happens far away from the gun,can you tell me where is wrong?

[@CodeMonkeyUnity]

When you move an object in an animation it moves the Local Position of that object and not the Global Position Make sure your gun has a parent object and move the parent while leaving the gun always at its origin local position

[@byDiAbLo21]

Hi, I've got a problem, all seems good but when my mouse is close/over the aim transform my gun starts flickering how could I solve this?

[@anonymoussloth6687]

Add a gun rotation dead zone which means set a specific threshold for the mousePosition - player's position so that the gun doesn't rotate when the mouse is really close to the player.

[@julius6521]

When I use your script or countless others i that I have tried, the gun just rotates to some direction (random depending on position) and then stays like that. When I move the mouse it only rotates insanely little. I'm in the Unity 2019 version and I have no idea what I'm doing wrong. Help?

[@CodeMonkeyUnity]

Verify that you're grabbing the Mouse World Position and doing all the math correctly. Add a bunch of Debug.Log in various places kzbin.info/www/bejne/a5rVp2ZmYseHgNk

[@AustraliaM69]

how did u get it to actually rotate around the player? it rotates in spot at 5:25 but rotates all around the player after you add hands? what am i missing

[@CodeMonkeyUnity]

It always rotates around the pivot, so you move the child objects to some offset which will cause it to rotate around the pivot unitycodemonkey.com/video.php?v=NsUJDqEY8tE unitycodemonkey.com/video.php?v=qa5WBatZ830

In that line the only thing that could be null is the aimTransform, use Debug.Log to verify unitycodemonkey.com/video.php?v=5irv30-bTJw Remember that Find(); is case sensitive, the name must match the child name exactly
