Has anyone come up with an example of how to make a circle gesture on the screen? Essentially holding down your finger, drawing a circle, then lifting your finger back up? Furthermore, I'm curious how to tell between clockwise and counter clockwise circles.
A circle around a fixed point or an arbitrary point? I could probably figure out how to do it from a fixed point, but an arbitrary point could prove to be a challenge... at least from my way of thinking.
From a fixed point. The center of the screen, actually. I have a semi-working model right now but it's pretty goofy.
I have four zones (ABCD), each a quarter of the screen. They meet in the middle. Basically, during a current touch goon from one to the next clockwise adds 1 each time the cursor lands on a new zone. Counter clockwise subtracts 1. The counter being manipulated is the speed of a spinning circle's rotation. It works but it doesn't feel quite smooth. Kinda clunky.
I'm also going to be searching around about swipe speed. I'm curious if there's a widget for it. If not, it shouldn't be too terribly hard to determine. I'm using speed Nd direction of swipes for the first time so it's something new to learn.
Is there any way to determine triangular shaped zones based off XY coordinates, rather than me making a giant invisible "pizza" in the background that divides the screen? I think having 8 areas works better than the 4 I mentioned above.
Who knew circular movements were so much work!?

I also remember doing a circle check once on another project in a totally different way:
I had an active object in the center, and had it always look at object2
If object 2 got close enough to the center, I set the center object's valueA to 528 (528 is 1-32 added together), and had a condition like:
everytime the center object's direction value has changed, subtract the center objects direction value from valueA.
Center object's value A = 0, a circle has been completed.
Pineapple, how did you prevent the user from just scrubbing their finger left and right repeatedly until the center objects vale A read 0?
well, it that little example I described, the game was checking if the player's space ship (asteroids type movement) was orbiting around a planetoid. It would have been really hard to go back & forth.
The clock hands example is probably of more use to you. You could probably just modify either of those 2 examples a little to get the desired result.
Why not have 4 squares sited around the fixed point that become 'activated' when the users finger is dragged across them. That way you could work out clockwise and anti-clockwise. Obviously if the user takes their finger off the screen or is not over one of the objects then unactivate them all.
^ That's what I've been doing. The results aren't quite seemless.
Here is an example modified from my "clock" example.
You can start the circle movement from any point, and the circle will complete after a full 360 degrees. Tests for both clockwise and counter clockwise movement.
It's kind of sloppy, but it works.
