ActionScript Animation
Kosal had a problem pausing between tweens. We went through several revisions.
First I suggesting defining the tween properties via array and using anonymous functions passed to the setTimeout function.
We found out anonymous functions were a no-go in his version of ActionScript. Then, I suggested using globals, which resulted in the following code:
// globals
var g_mc,
g_a,
g_b,
g_c;
function animate () {
var arr = [
// mc, slideto vars, timeout
[ car, 200, 100, 1, 10 ],
[dog, 200, 100, 5, 5]
];
var timeout = 0;
for ( var i = 0; i < arr.length; i ++ ) {
var item = arr [ i ];
g_mc = item [ 0 ];
g_a = item[1];
g_b = item[2];
g_c = item[3];
timeout += item[4]; // total seconds to timeout
setTimeout ( doSlide, timeout );
}
}
function doSlide () {
g_mc.slideTo ( g_a, g_b, g_c );
}
</code>
That had a problem with it, as when I was visualizing the code, I forgot that the globals would always point to the last array. We finally wound up with the code below, which uses recursion instead.
<code lang="actionscript">
// globals
var g_index = 0,
g_arr = [];
function animate () {
g_index = 0;
g_arr = [
// mc, slideto vars, timeout
[ car, 200, 100, 1, 10 ],
[dog, 200, 100, 5, 5]
];
doSlide ();
}
function doSlide () {
if ( g_index < g_arr.length ) {
var item = g_arr [ g_index ];
g_mc = item [ 0 ];
g_a = item[1];
g_b = item[2];
g_c = item[3];
g_mc.slideTo ( g_a, g_b, g_c );
g_index ++;
setTimeout ( doSlide, item[4] );
}
}
