I am currently making a game which involves a sprite image to always face the mouse. I have looked everywhere for a function that does that, but I can't seem to find one. Is there a way to calculate an angle of difference from one point to another? Ex:
angleA_X, angleA_Y = (12, 52)
angleB_X, angleB_Y = (45, 11)
deltaX = angleB_X - angleA_X
deltaY = angleB_Y - angleA_Y
tan = deltaX/deltaY
formula = math.atan(tan)
formula = formula ** 2
formula = math.sqrt(formula)
formula = math.degrees(formula)
print(formula)
This would calculate the difference in the angle, but this does not return the right anwser. Any idea what is wrong?
You're doing some math operations that are not needed (such as ** 2 and sqrt), you just need math.atan2 (this will yield the angle in radians between A and B):
math.atan2(angleA_Y - angleB_Y, angleA_X - angleB_X)
math.atan2 has the benefit of also working when deltaX == 0.
