Math genius wanted!!

In the example below the MC's x value increases. When the clip is at a given point it goes back and increases again and so on. When adding acceleration ("acc") the animation is faaling apart. My problem is figuring out the new startingpoint (startx, or the endpoint(max_x)) to make the animation look smoothe?

onClipEvent (load) {
max_x = 350
this.startx = this. _x
}
onClipEvent (enterFrame) {
acc = acc+0.05;
this._x = this._x+5+acc;
if (this._x>max_x) {
this._x = this.startx;
}
}

Dear reader, yeah YOU!!
Let me know if I'm making myself understandable.

I think you have too many accelerating components
all you really need is:

onClipEvent (enterFrame) {
acc = 0.05;
this._x = this._x + acc;
if (this._x>max_x) {
this._x = this.startx;
}

tweek the value of acc to get the right amount of acceleration.

Hi harry,
Thanx for your reply.

I don't see the acceleration in your example?!

this._x = this._x + 0.05
is not acceleration.
Hit me baby one more time!

Sorry, it should be this:

onClipEvent (enterFrame) {
acc = acc + 0.05;
this._x = this._x + acc;
if (this._x>max_x) {
this._x = this.startx;
}

Tanks again Harry,
That was my idea.

If you imagine a movie clip looking like this with increasing x-value.

The problem is that (because of the acceleration), max_x is different for each run through, and therefore the animation isn't smoothe.
