Question

I have a simple code that seems to be giving strange results.

var startPoint:Point = new Point(x, y); // a point
var r:Number = path[i].row + (-Math.floor((length * 2 + 2) / 2)); // just some math
trace(r); // the math checks out and gives a 3
var tey = startPoint.y + r; //this gives a really strange return....
trace(startPoint.y + r, tey); // this works, and then gives the strange return.

the return is

3
10 7function Function() {}

as

var tey:Number = startPoint.y + r;
trace(startPoint.y + r, tey);

the return is

10 NaN

IDE is FlashDevelop if you feel that information is important.

Additional Info/Testing:

trace(startPoint.y);

traces as

7

:Number

var tey:Number = startPoint.y + r;
trace(tey);

equals

NaN

Number()

var tey = Number(startPoint.y) + r;
trace(tey);

equals

7function Function() {}

(excuse my poor post layout, I’m still inexperienced with stackoverflow’s editing system and am working on making this a little cleaner)

Answer 1

I discovered the issue, it was with a part of the code that I appended out of my sample above.

var startPoint:Point = new Point(x, y); // a point
for ( /*for stuff*/ ){
    var r:Number = path[i].row + (-Math.floor((length * 2 + 2) / 2)); // just some math
}
trace(r); // the math checks out and gives a 3
var tey = startPoint.y + r; //this gives a really strange return....
trace(startPoint.y + r, tey); // this works, and then gives the strange return.

being var’d inside of the for loop made it act oddly when used outside so I had to move the var assignment outside of the loop and use as normal. A strange occurrence, but I should have knew better.
