I’m trying to make a box change dimensions with a spring motion. In terms of doing the resizing it works normally, but when I try to apply a modified version of the spring tutoral code it doesn’t work. I’ll copy and past the code and attach my file, any help would be appriciated.

onClipEvent (load) {

// inertia relates to the quantity of energy that

// the spring will carry

// inertia = 1 would mean that the spring doesn’t

// loose any energy, and that it will oscillate

// forever

inertia = 0.7 ;

```
// k relates to the spring, and how "hard" it will be.
// The higher k the faster the mass will come back.
k = 0.2 ;
boxW = 200;
boxH = 200;
```

}

onClipEvent (enterFrame) {

// Centers movie in _root

centerX = 275;

centerY = 200;

movieW = Math.floor(_width/2);

movieH = Math.floor(_height/2);

xCenterLoc = (centerX-movieW);

_x = xCenterLoc;

yCenterLoc = (centerY-movieH);

_y = yCenterLoc;

```
// Spring Calculations
cornerHeight = (topLeftCorner._height + bottomLeftCorner._height);
cornerWidth = (topLeftCorner._width + topRightCorner._width);
// We calculate the distance to the mouse
deltaW = -_width + (boxW + cornerWidth);
deltaH = -_height + (boxH + cornerHeight);
//We calculate the amount by which the mass will to move
wp = wp * inertia + deltaW*k ;
hp = hp * inertia + deltaH*k ;
//We move it
topBar._width += wp ;
bottomBar._width += wp;
leftBar._height += hp ;
rightBar._height += hp;
// Move right side graphics to new X position
xLoc = topLeftCorner._width + topBar._width;
topRightCorner._x = xLoc;
rightBar._x = xLoc;
bottomRightCorner._x = xLoc;
// Move bottom graphics to new Y position
yLoc = topLeftCorner._height + leftBar._height;
bottomLeftCorner._y = yLoc;
bottomBar._y = yLoc;
bottomRightCorner._y = yLoc;
```

}
