Mouse move problems in different computers

Questions & Answers

Hi there. I’m working on a firs person adventure like Amnesia or Penumbra.
The idea is to create a smooth movement for the mouse: not to look directly to the mouse position but with a deceleration (with transition).

I did it and it works fine in my computer but when I test it on other computers it moves slower and even makes some drastic jumps.

The first time I thought the problem was the DT but I couldn’t find the mistake in the code.

Here is the code (I simplify it):

/* Constants: mouseSensitivityX, mouseSensitivityY, rotationYMin, rotationYMax and rotationLerpSpeed */

newRotation = new Vector3 ( currentRotation.x, currentRotation.y, currentRotation.z );

newRotation.y = newRotation.y + (Input.GetAxis( "Mouse X" ) * mouseSensitivityX * Time.deltaTime);
newRotation.x = Mathf.Clamp( newRotation.x - (Input.GetAxis( "Mouse Y" ) * mouseSensitivityY * Time.deltaTime), rotationYMin, rotationYMax );
           
currentRotation.x += ( newRotation.x - currentRotation.x ) * ( rotationLerpSpeed * Time.deltaTime );
currentRotation.y += ( newRotation.y - currentRotation.y ) * ( rotationLerpSpeed * Time.deltaTime );

I’m mising something? Is the DT necesary where I put it? Do you think there is a better way to do it?

Thank you!

you multiplying to Time.deltaTime twice.

try this:

if (!attributes.lockLookInX)
  currentRotation.x = Mathf.Clamp(currentRotation.x + Input.GetAxis( "Mouse Y" ) * mouseSensitivityY * Time.deltaTime * rotationLerpSpeed, rotationYMin, rotationYMax);

if (!attributes.lockLookInY)
  currentRotation.y = currentRotation.y + Input.GetAxis("Mouse X") * mouseSensitivityX * Time.deltaTime * rotationLerpSpeed;

eyes.localEulerAngles = V3.SetXResetYZ( currentRotation.x );
transform.eulerAngles = V3.SetYResetXZ( currentRotation.y );

I check it on other computer and it continues not working.

In my computer it works fine but the speed continues changing when I check it on other computers.

Here is the code (updated):

mouseLookRotation.x = Mathf.Clamp( mouseLookRotation.x - (Input.GetAxis( "Mouse Y" ) * Time.deltaTime), rotationMin, rotationMax );
mouseLookRotation.y += Input.GetAxis( "Mouse X" ) * Time.deltaTime;

lookRotation = new Vector3 ( mouseLookRotation.x, mouseLookRotation.y, mouseLookRotation.z );

float lerpSpeed = lookLerpSpeed * Time.deltaTime;

if ( lerpSpeed > 0 )
{
    Quaternion currentRotation = Quaternion.Euler( lookRotation );

    head.rotation = Quaternion.Slerp( head.rotation, currentRotation, lerpSpeed );
    head.localEulerAngles = new Vector3 ( head.localEulerAngles.x, 0F, 0F );

    transform.rotation = Quaternion.Slerp( transform.rotation, currentRotation, lerpSpeed );
    transform.eulerAngles = new Vector3 ( 0F, transform.eulerAngles.y, 0F );
}

Any idea?

Thank you.
