Getting smooth zooming...

by Kaya Dogan · in Torque Game Engine · 05/28/2006 (4:52 am) · 2 replies

After merging the zooming 3rd person camera and modifying a bit, I noticed, that the zoom is not as smooth as we want it to be. Here's the code, which is being executed in the default.bind.cs:

//Camera Zoom in and out, 3rd person view - Mouse Wheel
function handleMouseWheel(%val)
{
   // Check if the wheel scrolled up or down
   if( %val > 0 )
         commandToServer('ZoomInCamera'); //Mwheel Up

   else
         commandToServer( 'ZoomOutCamera' );//Mwheel Down

}

moveMap.bind(mouse, "zaxis", handleMouseWheel );

We tried with schedule() but failed. Maybe you can help us by giving us the right direction or maybe some code.
Thanks in advance.

That code doesn't show anything to do with zooming. It's just telling us you bound the mousewheel to a zoom in and zoom out function. These are the functions we need to see.

To get smooth zooming I use a switch statement which increments / decrements the FOV by small amounts each time the appropriate function bound to the mwheel is called.

We basically use the following resource for zooming camera:

I just modified the engine-sources, so the value given to the zoom function will be divided by 10, so +1 becomes +0.1 in order to make it scroll a bit slower.
