Controlling Speed of a Moving Canvas
I have a script that practically create a circle and move it in a certain angle.
import numpy my_canvas = canvas() BigR = 150 SmallR = BigR*5/6 xTiny0 = 0.01 yTiny0 = SmallR+((BigR-SmallR)/2) RTiny = (BigR-SmallR)/1.5 RES = 200 # step resolution TIME =1# seconds R = yTiny0 # Circle radius def move_by_angle(origin, angle, r): alpha = numpy.arctan(origin / origin) angle_step = angle/RES path =  for point in range(0, RES): beta = alpha + point*angle_step path.append ([r*numpy.sin(beta), r*numpy.cos(beta)]) return path start = [yTiny0,xTiny0] * R angle = numpy.pi*-0.5 path = move_by_angle(start, angle, R) for step in range(0, RES): xTiny0, yTiny0 = path[step], path[step] TinyCircle = my_canvas.circle(xTiny0, yTiny0, RTiny, fill=True, color= '#404040') my_canvas.show() my_canvas.clear()
Though it works, my limited experience with programming is facing me with a problem. My problem is that the moving circle has sort of "innate speed"; it seems like the last "for" loop enforce the circle a speed that i'm not sure how to control. My goal is to determine or measure the speed and to change it according to a certain radius or angle.
Can anyone help me with that?
