This should really only be encouraging for beginners to write new software!
You can use this without permission (no licencing).
Also it's kind of a nice and easy task if you want to do some maths again
If you have questions or spotted a mistake, please tell me!
Have fun!
PHP Code:
from math import pow, sqrt
def calcposattime(current, destination, speed, time):
# extract
currentx, currenty = current
destinationx, destinationy = destination
# errorpreventing
if (currentx == destinationx) and (currenty == destinationy):
return (0, 0)
# calc delta
deltax, deltay = currentx - destinationx, currenty - destinationy
# calc distance from current to destination
distance = sqrt(pow(deltax,2)+pow(deltay,2))
# distance: dis travelled in time: t with speed: v => dis = v * t
distance_travelled = speed * time
# now see how much of the final distance we made and multiply with our delta coordinates:
delta_travelled_x = deltax * (distance_travelled/distance)
delta_travelled_y = deltay * (distance_travelled/distance)
# and now add it to our current location
newx, newy = currentx - delta_travelled_x, currenty - delta_travelled_y
return (newx, newy)
