From file to mask ... syntax problem

Hello everybody...
I have some graph/chart to do. I want to do mask/shape (AE7) from data file.
I found some help at
http://www.motionscript.com but i'm stuck.
My problem lies in syntax. I don't know how to "push" my variable TempVar in to myShape.verticles
Code: Select all
var newMask = mySolid.Masks.addProperty("Mask");
newMask.inverted = false;
var myMaskShape = newMask.property("maskShape");
var myShape = myMaskShape.value;
while (!myFile.eof)
{
i ++;
text = myFile.readln();
if (text == "") text = "\r" ;
{number = parseFloat(text);
TempVar[i]=[i,number];} <--- this line is my problem ;)
}
myShape.verticles = TempVar;
myMaskShape.setValue(myShape);
Does anyone know how to do that?
May be there is much elegant way to solve my task.
BTW. This is my first post at the ae enhancers forum and any english forum at all, therefore...
I'm sorry for my english

Here is my post on creating animated mask.
I also started off by visiting motion script.

I hope this helps.

Thanks for answer...
I'm reading and reading and reading and I'm still not understanding. (I can't find a solution)
I want to create shape (mask) from pairs of numbers. Sometime will be 5 pairs and sometimes 105. I don't know how to "push" another vertice after previous. When I used "myShape.verticles
= myPairOfNumbers" or "myShape = myPairOfNumbers", AE made a open square (I set myShape.closed = false)
Can I use variable myShape like an array ?
Where can I find a list of AE Script's method ? (The file ae7_scripting_guide.pdf from adobe site is very poor of it)

From what I can tell in your loop, you are assigning the loop index as one of the data values for a point.
Consider this line...
Notice, you are using the loop index i as one of your data values.
Now consider the line from my exmaple post.
Code: Select all
myShape.vertices = [[5,5],[5,45],[45,45],[45,5]];
Which could also be written like this...(ie your form).
So this is the trouble line in your example.
I'm not sure what the parseFloat function does, but you need some way to get TWO numbers not just a single number.
More pseudo code...
Code: Select all
numberX = parseFloat(text);
numberY = parseFloat(text);
TempVar[i]=[numberX, numberY];
Because I do not know what format your data is in, I can not go any further, but perhaps you get the idea...

1. parseFloat(text) returns float type of number from text
2. in my "trouble line": TempVar=[i,number]; are two numbers, but I think AE don't get it like a pair because one is integer type, second is float type.
Finally, I used write-on effect to solve my task (write chart from txt file), but now I'm back to play with masks in another problem. Soon I'll report my progression of it.
