Congratulations on the channel! I have a question, does this work with Third Person Standard Asset (the latest one that comes with New Input)? I ask about this, because I have a problem that I don't know what else to do, in all xiaomis my virtual look input rotates the cameras perfectly, however, in samsungs it rotates super fast. Thanks!

Hello thank you for tutorial. I have a problem. I am using Unity starter assets with a third person character combined your script. The problem is when i move my joystick to the forward and even i change the rotation of camera, my character is not moving the same rotation with camera. Can you help me please?

Hello! Your tutorials are excellent and I have been following them starting from Character Animation Setup up to this video and everything works perfectly but I have encountered a same problem another person had where the camera rotation works when moving with the mouse but when I try to run it in my phone both the touch and the mouse input stop working, I tried it via my phone using Unity Remote and also build the game and install on phone but still same. Any idea how to fix? Appreciate the help!

Great content, but it has some issues when trying to control the camera and move at the same time which is a natural thing to do in mobile game. Having both figures on screen cause the camera to be confused between which to follow which makes weird behavior.

Hi! great tutorial... thank you! but I have a problem... everything works fine with mouse and pc but when I used unity remote, it didn't work with touch. am I mmissing something here? I used xiaomi 11t Pro. unity 2021.3.29...

how about cinemachine freelook that uses the new input system, since it doesnt have field for axis name? how can you fix its unwanted rotation

when a write "out Vector2" it gives me an error: "Assets/scripts/Cameracontrol.cs(21, 8): error CS1644: Feature `declaration expression' cannot be used because it is not part of the C# 4.0 language specification" pls help ;(


edit: don´t worry i have just got the solution.
it was because i have an older version of unity, to fix that.
you need to create the var out of the conditional.
like this:

" *Vector2 posOut;*
if
imgCamControlArea.rectTransform,
eventData.position,
eventData.enterEventCamera,
out posOut))"

I try the script, it works perfectly by using mouse clicking to rotate camera. But when i try to test on mobile, it doesn’t work. Is it missing any script to receive touch value and change it into strMouseX and strMouseY?
