Salve a tutti!!
C'é qualcuno di buon cuore che mi può "tradurre questo codice", con qualche spiegazione, in modo da poterne capire la tecnica?.. sto cercando di imparare la logica con la quale vengono scritte certe funzioni, ma da solo é un bel problema...

fscommand("allowscale", false);
//Creates a unique ID number for each bounce function call
uniqueBounceID = 0;
function bounce(param, endingVal, clipName, speedFactor, bounceFactor) {
//Do not run if the clipName does not exist
if (clipName._x<>undefined) {
//Clear old setIntervals with same param name that might still be firing - prevents the clipName movie from being caught between two different parameter values
clearInterval(_root["bounceInterval"+clipName[param+"ID"]]);
//Reassign variables to make them private variables of the movie clip
var bounceID = _root.uniqueBounceID++;
clipName["param"+bounceID] = param;
clipName["endingVal"+bounceID] = endingVal;
clipName["speedFactor"+bounceID] = speedFactor;
clipName["bounceFactor"+bounceID] = bounceFactor;
clipName["startingParamVal"+bounceID] = clipName[param];
clipName["changedParamVal"+bounceID] = 0;
//Store the bounceID for this parameter into a variable in the clipName movieclip - used to clear the setInterval if the movie clip is removed before the function completes
clipName[param+"ID"] = bounceID;
//Bounce function called from the setInterval
clipName["callBounce"+bounceID] = function () {
//If the clip no longer exists, clear the setInterval
if (clipName._x == undefined) {
clearInterval(_root["bounceInterval"+bounceID]);
} else {
// Don't fire if the destination position is met
if (clipName["endingVal"+bounceID]<>Math.round(clipName[clipName["param"+bounceID]])) {
// Modify the changedParamVal by using a simple friction equation
clipName["changedParamVal"+bounceID] = clipName["changedParamVal"+bounceID]*clipName["bounceFactor"+bounceID]+(clipName["endingVal"+bounceID]-clipName["startingParamVal"+bounceID])/clipName["speedFactor"+bounceID];
// Increment the startingParamVal by the new changedParamVal
clipName["startingParamVal"+bounceID] += clipName["changedParamVal"+bounceID];
// Snaps bouncing object to the pixel to reduce blinking effect and keep fonts pixelized
clipName[clipName["param"+bounceID]] = Math.round(clipName["startingParamVal"+bounceID]);
} else {
//Ensure final destination
clipName[clipName["param"+bounceID]] = clipName["endingVal"+bounceID];
// Clear the setInterval
clearInterval(_root["bounceInterval"+bounceID]);
}
}
//trace(clipName+" "+bounceID+":"+clipName["param"+bounceID]+" = "+clipName[clipName["param"+bounceID]]);
};
//Call the bounce function 100 times per second
_root["bounceInterval"+bounceID] = setInterval(clipName["callBounce"+bounceID], 10);
}
}
Spero nel vostro aiuto
