[code]all right! we have the board, we have the pieces. it's definitely time to make them... move. (thunder sound fill) put an instance of the clock on the stage and name it something complex and unreasonably odd like "clock". just for fun. this clock's gotta be a movieclip for this to work, you know. then select the clock and add the following code to it (you should see something like "actions - Movie Clip" on the Actions Pannel):onClipEvent (enterFrame) {
// gets the time information and stores in a variable called "now"
now = new Date();
// assigns values individually
h = now.getHours();
m = now.getMinutes();
s = now.getSeconds();
// angle adjust relative to the hours
setProperty(_root.clock.hrs, _rotation, (h+1)*30);
// angle adjust relative to the minutes
setProperty(_root.clock.min, _rotation, m*6);
// angle adjust relative to the seconds
setProperty(_root.clock.sec, _rotation, s*6);
}
now for some explanation. let's brake it! uhm, just drop the baseball bat, son.
onClipEvent (enterFrame) {
this opens up an event to be executed by the clock movieclip. at every second, this script will repeat, creating a nice tick-clock effect!
now = new Date();this gets the current time and stores it in a variable called "now" all the time. cus now IS all the time. and the clock hands use this variable to display time correctly all the time! neat, huh? h = now.getHours(); m = now.getMinutes(); s = now.getSeconds();now we separate hours from minutes and seconds. very useful ahead. setProperty(_root.clock.hrs, _rotation, (h+1)*30);here we set the angle of the hours hand using the hour provided by New Date() and multiplying it by 30. why 30? divide 360, wich is the number of degrees in a circle (any circle, even if you didn't draw it) by 12, the number of hours in a clock (any clock, even for the Gestalt freaks). and (h+1) will assure you'll never get a zero (cus midnight is displayed as 00:00.) setProperty(_root.clock.min, _rotation, m*6); setProperty(_root.clock.sec, _rotation, s*6);these lines have the same function, operating on minutes and seconds. because you get as many minutes in an hour as you get seconds in a minute, the numbers are strictly the same, and they each jump on increments of 6 degrees.
