Hi,  
I’m sure this is very simple, been searching the boards for ages, but can’t find the right solution. I want to create a simple actionscript rectangle mask which slides down to reveal an image when an swf is opened.

I would use a standard tween but the image is large and I want to have some nice easing going on.

This is what I have to move the rectangle:

onClipEvent (load) {  
this.\_y = 50;  
}  
onClipEvent (enterFrame) {  
if (this.\_y\<300) {  
this.\_y += 5;  
}  
}

I found this script for the easing, but I’m not sure where it goes in the above code:

k = elapsedTime/duration; // k = 0-1  
k = k_k_(3-2\*k); // apply easing  
\_x = start + (target - start)\*k;

I’m hoping its just a case of piecing these two bits of code together.  
Any help would be greatly appreciated, (Flash Mx6)

Cheers!

try this:

onClipEvent (load) {  
speed = 3;  
this.\_y = 50;  
}  
onClipEvent (enterFrame) {  
if (this.\_y\<300) {  
this.\_y += (targetdesired- this.\_y)/speed;  
//replace targetdesired with where u want ur rectangle to be placed  
}  
}

i hope it helps 🙂
