Motion that doesn't work inside function

Report · Jun 03, 2015

So I have this motion script which I copied from Cs6 as "Copy Motion as AS3". It works fine until I tried to control it with a mouse event function. So what am I missing? it works fine outside the function but not at all inside.

import fl.motion.AnimatorFactory;

import fl.motion.MotionBase;

import fl.motion.Motion;

import flash.filters.*;

import flash.geom.Point;

var __motion_NewBall_7: MotionBase;

theButton.addEventListener(MouseEvent.CLICK, on_press1);

function on_press1(event: MouseEvent): void {

if (__motion_NewBall_7 == null) {

__motion_NewBall_7 = new Motion();

__motion_NewBall_7.duration = 60;

__motion_NewBall_7.addPropertyArray("x", [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, -4.02143, -8.04286, -12.0603, -16.0857, -20.1071, -24.1246, -28.15, -35.6987, -43.2474, -50.7885, -58.3447, -65.8934, -73.4346, -80.9832, -88.5395, -96.0882, -103.637, -111.186, -118.727, -126.283, -133.824, -141.38, -148.929, -156.478, -164.026, -171.575, -179.124, -186.672, -194.221, -201.77, -209.311, -216.867, -224.416, -231.957, -239.506, -247.062, -254.611, -262.152, -269.708, -277.257, -284.805, -292.346, -299.903, -307.451, -315]);

move that AnimationFactory declaration outside your function just like you did with your MotionBase declaration.

nope, still doesn'r work, I get this error message:

I tested this script on both CC1214 and on CS6 and they both have the same problem. moving the var statements out of the function did not help but rather produced an additional error that I described above. at this point I'm clueless.

Report · Jun 04, 2015

what code are you using and what's on line 33 of frame 1 that's triggering that error?

Report · Jun 04, 2015

The code above is the entire code that I'm using. The stage have one button and one circle (myClip). The circle should drop down in a specific motion when clicking on the button, but when clicking on the button there is no motion. However, when the motion code part is outside of the function the movement of the circle is as expected. I'd like to control the motion and have it run only after clicking on the button. Maybe I'm using the wrong method but I don't know how.

copy and paste the code you're using and highlight line 33 of frame 1.

The error is on line 32 now since I played with the code moving things around.

don't use screenshots. copy and paste your code, in the future.

use:

var __animFactory_NewBall_7:AnimatorFactory; // <-just the declaration was to be moved. not the definition

outside your function and after creating your motion instance (inside your function body) use

__animFactory_NewBall_7=new AnimatorFactory(_motion_NewBall_7); // define it after the motion, _motion_NewBall_7 exists.
