hi all - and hello - first post an all.
I’ve created a carousel menu - looks good and scrolls well- but after importing the graphics and everything I just can’t get the objects to act as buttons - the buttons are created within the objects - and whilst they show the mouseover icon, mouse click just doesn’t work - code is below - men1,men2 ect are movie clip objects. thanks
var gPhase:Number = 0;
var gDelta:Number;
var gXamp:Number;
var gYamp:Number;
var gXcenter:Number;
var gYcenter:Number;
// rate of change
gDelta = 1;
// XY amplitude and offset for sin cos equations
gXamp = 220;
gXcenter = 800/2;
gYamp = 15;
gYcenter = 280;
_root.onEnterFrame = function(){
// rate of change depends on mouse distance from center screen
// gDelta is 1 when the mouse is at the screen edge and
// gDelta is 0 at center
gDelta = (_root._xmouse - (800/2)) / 225;
// sin and cos uses radians, and 2 PI radian is a full circle
// basically, gPhase only goes from 0 to 2 for forward rotation and
// 0 to -2 for reverse rotation
if(gPhase<2 && gPhase>-2){
gPhase = gPhase + gDelta / 100;
}
// otherwise, you reset to 0. just like after 360 degrees, you go
// back to 0 degrees

// rotation calculations for position
// I manually placed the registration point of the
// objects at the object center so it’ll scale without problems

// range is -gXamp to gXamp(amplitude)

// offset is gXcenter

// amplitudes, but to offset it so that the numbers don’t
// go into the negative direction

// with the remaining objects, you’ll want to offset the gPhase.
// A phase difference of 1 means 180 degrees difference.
// In this case, since 2 is a full circle,
// we want 2/3 difference because we have 3 objects
// this is 1/3 of the circle
