[flashpro] Help with timeline controller (simple maths?)

[Jonathan E]

hey santinilox,

i'm not too good at maths also, but here's something.
i think you can just "Math.round" the value of
(percent*totalIntervals), then add 1 to the result.

so if say you have 3 checkpoints like this:

|------------|------------|
0            1            2

This makes for 2 intervals. if the user clicks at 20%,
calculate it like this:

Math.round(percent*2)

which will return 0.4, which will be rounded to 0 by
Flash, and to which you would add 1, bringing you to
frame 1.

and if we try another scenario, and the user clicks at
40%, Math.round(percent*2) will return 0.8, which will
be rounded to 1 by Flash, to which you would add 1,
bringing you to frame 2.

so the code would be:

gotoAndStop (Math.round(percent*totalIntervals)+1);

totalIntervals being the number of checkpoints minus
1. This is kind of simplistic, but i hope it helps!
(and i hope it still works if you "scale the thing
up")
