ah this degree thing dont work for me... ima see degrees later but atm,
can i create an equation of straight line and use it to move my projectile along the vector? using 2 point formula and then entering a varying (i++ or something) in x coordinate to get y?
will it work?

ok apparantly my angle never changes... i cout'ed the sin(angle) and its always -0.8... now lemme see where i did the mistake that the angle isnt calculated properly :/

i used windows calculator for value of pi (ripped off some values after point(.) and i used this for mouse:
sf::Vector2i mousepos = sf::mouse::getPosition(window);
sf::Vector2i mousepos = sf::mouse::getPosition(window);

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
