Hello, hope someone can help…
I am using laco tweening prototypes [http://laco.wz.cz/tween/](http://laco.wz.cz/tween/) and have a little problem which im sure is easy to solve, but i just dont know how…
I have e.g 3 movieclips which i want to animate with a rollover from 3 different buttons - btn1 animates mc1, btn2 animates mc2 etc.
Each mc has the same animation (3 tweens - x,y and rotation) so i have set up a function for the three tweens using a variable for the mc name:
```auto
var my_mc = "mc1";
function PageTween() {
my_mc.tween("_x", 165, 1, "easeOutExpo");
my_mc.tween("_y", 75, 1, "easeOutExpo");
my_mc.tween("_rotation", 1, 1, "easeOutExpo");
}
```
this is so when i rollover btn2 i can change the var my\_mc to “mc2” so that i can reuse the function.
```auto
btn2.onRollOver = function() {
my_mc = "mc2";
PageTween()
};
```
but, it doesnt work. I am assuming that the tween ignores the variable.
is there some way inserting a calculation to get the variable instead of my\_mc at the start of the tween?
thanks for your time
Lee

}
for (i=1; i\<4; i++) {
this[“btn”+i].ind = i;
this[“btn”+i].onRollOver = function() {
PageTween(\_root[“mc”+this.ind]);
};
}[/AS] 🙂

Hi BlueNar,
Thanks for the quick response, i ahve tried the script provided, and in my main movie that im working on it had no effect, so i tried it on a fresh movie and found that when i included in the laco as:
#include “lmc\_tween.as”
i was gettting an error:
found Number where String is required.
for (i=1; i\<4; i++) {
I have uploaded the test here \>
[http://www.leeharding.net/test/tweenFunction.zip](http://www.leeharding.net/test/tweenFunction.zip)
i hope you can figure this one out as it is giving me a headache. Thanks for your time, i appreciate it.
regards
Lee

the code before the for loop
```auto
function PageTween(my_mc:MovieClip):Void {
my_mc.tween("_x", 165, 1, "easeOutExpo");
my_mc.tween("_y", 75, 1, "easeOutExpo");
my_mc.tween("_rotation", 1, 1, "easeOutExpo");
}
```

the problem lies within the laco tween class syntax, which Im unfamiliar with. I replaced it with the tween class to show that the function does work properly.

thanks - thats going to be helpful for something else im working on…
unfortunately im using the laco tween throughout the site that i need this for…
i will have to try something else… if you get any ideas, let me know.
is there any way i can just use the
```auto
function PageTween(my_mc:MovieClip):Void {
```
without the for loop?
thanks for your time
