Get Angle Value

taj_cc

I have one big circle on the seen, I am touching circle in different points. I want to get the angle value where I am touching in the circle. Can any one help me how can I get the angle value?

go to expression editor:

vectorToAngle(TouchX,TouchY)

Hope this helps!

The angle of what though? From the centre of the circle along the horizontal? Vertical? From the origin?

gyroscope

Hi RH, this should answer your question:

Hee! (Despite my attempt at humour, you might well understand the maths there; I surely don't!)

Basically, it's the angle made from the centre of the circle to the x,y loc of the touch point.
