how can i zoom in/out with orbit camera

#1 i have make some Orbit distance prototype code :)


in camera.h add public function

void setAddOrbitDistance(F32 distance);

in camera.cpp find function

Camera::validateEyePoint(F32 pos, MatrixF *mat)

// replace this
   if (pos != 0) 
   {
      // Use the eye transform to orient the camera
      Point3F dir;
      mat->getColumn(1, &dir);
      if (mMaxOrbitDist < mCurOrbitDist)
         pos *= mMaxOrbitDist;
      else if (mMinOrbitDist > mCurOrbitDist)
         pos *= mMinOrbitDist;
	  else
    	 pos *= mCurOrbitDist;

and add end of line

void Camera::setAddOrbitDistance(F32 distance)
{
	if(mMaxOrbitDist < mCurOrbitDist + distance)
		return;
	else if(mMinOrbitDist > mCurOrbitDist + distance)
		return;
	else
		mCurOrbitDist += distance;
}

ConsoleMethod( Camera, setAddOrbitDistance, void, 3, 3, "(F32)distance" "- distance camera ")
{
	object->setAddOrbitDistance(dAtof(argv[2]));
}

in scripts/client/default.bind.cs

function mouseZoom(%val)
{
   // If wheel was scrolled forward
   // move camera closer to the ground
   
   %CCamera = LocalClientConnection.camera;
   
   if(%val > 0)
   {
      %CCamera.setAddOrbitDistance(0.5);      
   }
   // If wheel was scrolled back
   // move camera away from the ground
   else
   {
      %CCamera.setAddOrbitDistance(-0.5);
   }
}

moveMap.bind(mouse0, "zaxis", mouseZoom);

thx :)

#2 but anyone mouse zoom change to smooth?

above code so stiff zoom in/out :(...

#3 I was wondering why you didn't just change the setFOV() .... though that's also "stiff zoom in/out".

#4 @Steve

amm.. i have make RPG game whth click move

What are you talk about?.. i dont understand

and.. im from korean sry my bed english :)

#5 default.bind.cs ---- zoom in stock/normal Torque. But this is not smooth either...

// Zoom and FOV functions
//------------------------------------------------------------------------------

if($Pref::player::CurrentFOV $= "")
   $Pref::player::CurrentFOV = $pref::Player::DefaultFOV / 2;

// toggleZoomFOV() works by dividing the CurrentFOV by 2.  Each time that this
// toggle is hit it simply divides the CurrentFOV by 2 once again.  If the
// FOV is reduced below a certain threshold then it resets to equal half of the
// DefaultFOV value.  This gives us 4 zoom levels to cycle through.

function toggleZoomFOV()
{
    $Pref::Player::CurrentFOV = $Pref::Player::CurrentFOV / 2;

    if($Pref::Player::CurrentFOV < 5)
        $Pref::Player::CurrentFOV = $Pref::Player::DefaultFov / 2;

    if($ZoomOn)
      setFOV($Pref::Player::CurrentFOV);
    else
      setFOV($Pref::Player::DefaultFOV);
}

function setZoomFOV(%val)
{
   if(%val)
      toggleZoomFOV();
}

$ZoomOn = false;

function toggleZoom(%val)
{
   if (%val)
   {
      if (!$ZoomOn)
         commandToServer('getZoomReticle');
   }
   else
   {
      clientCmdUnSetZoom();
   }
}

moveMap.bind(keyboard, f, setZoomFOV); // f for field of view
moveMap.bind(keyboard, z, toggleZoom); // z for zoom

Don't worry, your English is better than my Korean ;)

#6 Thx Steve! :)

#7 Edit: nvm, my solution apparently only works in the shapeeditor window.
