FLASH: animating with Actionscript

[T.R. Henigson]

I receive the digest-mode but I haven't seen my post come up so I'm going

to resubmit it. I hope you all aren't receiving multiple copies.


Does Flash have a problem with accuracy of coordinates? I wrote some

Actionscript to animate an icon over a bar to rest and it rests at

different coordinates depending on whether it's coming from the left

or the right. It's animating by comparing the difference in its position

with the position of the resting point and then slowly adjusting its

position. From the right, it rests right on the mark. From the left,

it's about a tenth off. Have you heard of this? What's the problem?


MORE DETAILS: I am dividing the distance between the icon and it's point

of rest by 3 to introduce some latency into the animation. "logoX" is the

icon, "thisX" is the resting point in the following trace output


FROM THE RIGHT, WORKS NO PROBLEM - "difX" goes to 0 and "logoX" equals

"thisX"

logoX: 431.9 difX: -0.800000000000011 thisX:431.1

logoX: 431.6 difX: -0.5 thisX:431.1

logoX: 431.4 difX: -0.300000000000011 thisX:431.1

logoX: 431.3 difX: -0.199999999999989 thisX:431.1

logoX: 431.2 difX: -0.100000000000023 thisX:431.1

logoX: 431.15 difX: -0.0500000000000682 thisX:431.1

logoX: 431.1 difX: 0 thisX:431.1

logoX: 431.1 difX: 0 thisX:431.1

logoX: 431.1 difX: 0 thisX:431.1

logoX: 431.1 difX: 0 thisX:431.1


FROM THE LEFT, TROUBLE - "difX" never makes it to 0 and "logoX" never quite

equals "thisX"

logoX: 430.3 difX: 0.800000000000011 thisX:431.1

logoX: 430.55 difX: 0.549999999999955 thisX:431.1

logoX: 430.7 difX: 0.399999999999977 thisX:431.1

logoX: 430.8 difX: 0.300000000000011 thisX:431.1

logoX: 430.9 difX: 0.199999999999989 thisX:431.1

logoX: 430.95 difX: 0.14999999999992 thisX:431.1

logoX: 431 difX: 0.100000000000023 thisX:431.1

logoX: 431 difX: 0.100000000000023 thisX:431.1

logoX: 431 difX: 0.100000000000023 thisX:431.1

logoX: 431 difX: 0.100000000000023 thisX:431.1

logoX: 431 difX: 0.100000000000023 thisX:431.1



That's all. I really hope you can help,
