Width/2 producing strange fluctuations

1

Hey Everyone,

**EDITED TO AVOID CONFUSION :slight_smile: **

I’m sure this is a really basic problem and hope someone can steer me in the right direction.

I have moving objects on stage all with a width of exactly 100 pixels. They’re part of a collision array. I need to know their radii so I created a variable that looks like this:

radius = objectName.width/2;

You would think that this would result in 50. However, when I do a trace of their values in an enterFrame loop, I get a range of numbers that looks like this when the objects are standing still:


51.325
52.075
50
50
50
50
52.075
50
50
50
50
50
50
50
50
50
50
50
50
50
50
51.325
52.075
50
50
50
50
52.075
50
50

… and so on!

As you can see, some of the fluctuations are quite big. When the objects start moving, I see numbers that look like this:


50.725
52.15
51.975
50
50.725
52.15
51.975
50.725
52.15
51.975
52.15
51.975
51.975

I’m sure this is something very basic.

Does anyone have any idea what the problem could be?

**EDITED: Update **

I did some more checking. If I use trace(width/2) inside the enterFame loop of the object’s class itself, I see the same fluctuations.

However, when I declare a _radius property in the constructor and initialise it as:

_radius = width/2;

the number remains stable.

Any ideas?

Thanks!! :slight_smile:
