rotate 2d vector by angle
rotate vector (x1, y1) counterclockwise by the given angle
(angle in radians)
newX = oldX * cos(angle) - oldY * sin(angle)
newY = oldX * sin(angle) + oldY * cos(angle)rotate 2d vector by angle
rotate vector (x1, y1) counterclockwise by the given angle
(angle in radians)
newX = oldX * cos(angle) - oldY * sin(angle)
newY = oldX * sin(angle) + oldY * cos(angle)get 2d rotation from 2 position math
Vector3 dir = new Vector3(position2.x - position1.x, position2.y - position1.y);
float angle = Mathf.Atan2(dir.y, dir.x) * Mathf.Rad2Deg;
