[FMX] Fading in dynamically loaded pictures

programming flash
1

Hi

Im making a site where I at the main frame load in a movie at a higher level. In this loaded movie I load in pictures dynamically with a function I use together with setInterval. I feel its a little bit anoying everytime a pic loads because it blinks. Is there maybe a smart way of fading the pictures in and out? I now it takes a lot of computer power using _alpha, and because I load in the pics I cant use tweening. Any suggestions?

thanks

Hi, try this code, it is from Mx tutorials.
buttons are: next & back
Mc for pic is : square

//initialize variables and properties
square._alpha = 0;
whichPic = 1;
//initiate change to new image when buttons are clicked
next.onPress = function() {
if (whichPic<5 && !fadeIn && !fadeOut) {
fadeOut = true;
whichpic++;
input = whichPic;
}
};
back.onPress = function() {
if (whichPic>1 && !fadeIn && !fadeOut) {
fadeOut = true;
whichpic–;
input = whichPic;
}
};
_root.onEnterFrame = function() {
// when a new Photo is selected, fade out, load new image, and fade in
if (square._alpha>10 && fadeOut) {
square._alpha -= 10;
}
if (square._alpha<10) {
loadMovie("…/images/image"+whichPic+".jpg", “square”);
fadeOut = false;
fadeIn = true;
}
if (square._alpha<100 && fadeIn && !fadeOut) {
square._alpha += 10;
} else {
fadeIn = false;
}
// limit input field
if (input>5) {
input = 5;
}
// initiate change to new image when Enter key is pressed
if (Key.isDown(Key.ENTER)) {
fadeOut = true;
whichpic = input;
}
};
// if a number is entered in the input field but Enter is not pressed, change
// back to current Photo number when clicking anywhere else
inputField.onKillFocus = function() {
input = whichPic;
};

Not mine , but works well.
I guess u can put preloaders on & convert to swf, the load swf instead of jpg… hope this not 2 stoopid. :nerd:

No probs, just remember 2 set the path for ur images ie
loadMovie("…/images/image"+whichPic+".jpg", “square”);

in this case the folder images is outside the current folder.

good luck!
