Analog 60 second timer- How to make the hand rotate

[mballaz]

Hi, i'm new to turing and i was wondering how i can make a hand on the 60 second analog timer rotate if the center of the clock would be at the center of the screen. the size of the circle doesn't really matter.
Thanks

You know one point (center), length of the hand, and the angle (time). Calculate the location of the second point, and draw a line in between.

use for loops and the drawline command

360 / 60 = 6

1 second = 6 degrees

Equation(Linear)
D=6s
D=6(60)
D=360

60=6s
s=6/60
s=10

i was hoping it would be like the rotating house example, so that i wouldn't need to redraw the line

there are probably commands you can use, however, the things mentioned above combined with simple trig should be more than enough.

So you would rather redraw a picture? Either way, to animate something you'll have to redraw something.
