circular wipe /masking needed

[jdeville]

hi

i am sure i have done this before - but i want a mask over my image that will reveal the image in a clockwise motion

i am trying to think of a way that involves tweening but for the moment - i am stumped - any suggestions


thanks

You mean a circular clock-like thing used in the movies?

Ok... Give me a sec to think about it.

yes

i think an earlier version of flash had something similar in its common libraries - an orange circle with a increasing segment going round from 0 dgrees to 360 degrees and then starting over again

i just would like to see how the masking was done so i can recreate something similar


thanks for looking

Yep here it is!:

Make half of the circle, and then make a mask of the first half of the circle. put it out of the masked area so that the first animated half is unseen, then tween the circle by turning it to rotation....

That makes it looks like the half of the first circle finished.

And then just stop the tween and make the next half.

The LAYERS will look like this:

-1sthalfCircleFinished *
-Mask:2ndHalfCircle **
---2nd Half Circle Tween **
-Mask:1stHalfCircle *
---1st Half Circle Tween *

* The "Finished Half Circle" sits on top AFTER the 1stHALF Circle is finished
** The 2nd circle needs to be the same speed as the first.

Careful the tween is NOT in the centre of the half-circle, it's in the mid-point of the whole circle
