Tween rotation?

programming flash

Ok, I’m not a programmer, so speak v…e…r…y…s…l…o…w…l…y…

I am trying to make a clock with rotating hands. I need to know how to get something to rotate and change the center of rotation. Make sense? I need the hands to rotate, but from the end and not from the middle.

This is not a working clock…just a logo with hands that continue turning like it’s out of control.

Any help is appreciated. :-\

When you go to turn your object into a symbol (pressing f8 or going to Insert/Convert To Symbol, etc, etc) in the Convert To Symbol panel you will see a block of 9 squares. Each one of those squares represents a location of your registration point. The registration point marks the center point of the clip. You can click on any of those 9 squares to change the location, so click on whichever one best suits where you need it to be.

Since this is tweens you can also use this method…

And also… if you ever wanted a real analog clock like this… here is a great tutorial ;)…

Thanks! That seems easy enough, but then how do I get it to rotate around that point?

Through Tweens… Just use the Free Transform tool. (check the regisration point tutorial in my last post to see where that is)

When you click on your clip with the free transform tool you will get the black bounding box, then if you hover your mouse over the corners while that bounding box is showing your mouse will then turn into a kind of curved line with an arrow at each end, this signifies you can click and drag to rotate the object.

Now that I went over how to rotate an object, now lets discuss the actual tween. With full 360 rotation something tweens get all floopy when you only use 2 keyframes. So to make it easier we will use 4 keyframes. Lets say each are about 10 frames apart.

Frame1 contains the keyframe with the clip in its first position (lets say up)

Frame10 contains the keyframe with the clip in its section position, which in clockwise would be right.

Frame 20 will contains the keyframe with the clip in its third position which will be down.

Then of course Frame 30 will contain the keyframe in its fourth position to the left and Frame 40 will contain the clip pointing back to the original position of up.

Now connect all these keyframes with a simple motion tween and voila.
