Hey guys. long time no see~ Q__Q

Ive got a question :-? is it possible to implement the mouse wheel? well some further explanation.
I'm doing some isometric camera scripting right now and I want to zoom in and out by mouse wheel, but I dunno if it is possible at all to use the mousewheel for this oO.
If so I would be glad if someone could tell me how to get the mousewheel to work v_v

mickey.z

wow thanks for the quick answer.
now all is working fine =) thank you!

Maybe this will help!
mouse_wheel = sys_metrics(75);
This will check if the mouse wheel exists.

Then mickey.z will control the arc like the code below.
if (mouse_wheel != 0) { // wheel present?
// then use the wheel to zoom in and out
camera.arc -= 1.0 * mickey.z * time_step;
}
else { // wheel not detected
// use the "Home" and "End" keys to zoom in and out
camera.arc -= (key_home - key_end) * time_step;
}
