Hello,
I trying to make my sprites move randomly, I have defined x, y randomly according to the window size, than gave vx, vy value for speed, and every clock.tick i am updating the x and y value with vx and vy. I tried to set an angle and move the sprite from the new angle but it wasn't good.I will be glad if someone will help me.
the object class (a part from it)
