Graphics / Angle between 2 points
« on: August 21, 2014, 08:08:32 am »
Hello everyone,
i am trying to get the angle between 2 points (1 of player and other of mouse).
i use this:
float getangle(float _x1,float _y1, float _x2, float _y2) // x1 and y1 are pos of mouse and x2 and y2 are pos of player
{
float _ang, _pi = 3.1428;
_ang = atan2(_y2 - _y1,_x2 - _x1) * (180/_pi);
return _ang;
}
but it only gives me 4rth quadrant angle about 45 degree.
i saw another topic about it but was unable to understand... please help
