Hi all
I want to create a golf ball flight animation. I have all the datas and formulas I need but I’m struggling on how to animate it.
// Data of an 8 Iron shot
var startX:Number = 0;
var startY:Number = 300;
var maxHeightX:Number = 88;
var maxHeightY:Number = 26;
var landingX:Number = 143.02;
var landingY:Number = 300
var endX:Number = 145;
var endY:Number = 300;
var velocityX:Number = 17;
var velocityY:Number = -18;
var time:Number = 0;
var timeOfFlight:Number = 5.67; //in seconds
var gravity:Number = -9.8+velocityX^2;
//I would also like to add the drag effect (friction)
var friction:Number = 0.3;
//I also have some more datas that could be helpfull
var launchAngle:Number = 33
var horizontalLandingAngle:Number = -7;
var verticalLandingAngle:Number = 82;
// now here is the formula to calculate the actual x and y during the animation…
// the Z is the is the initial direction let put that value to 1 form now.
var theX:Number = velocity * cos(z) * time;
var theY:Number = velocity * sin(z) * time + (gravity/2) * t^2;
I didn’t find any GOOD exemples of what I try to achieve so far.
I need help to make the transition beetween the ascending and descending part of the anim. I’m sure that, from here it sould be quite simple, but not for me 
Thanks for your time
