make player look at the mouse cursor
« on: July 11, 2011, 10:10:24 pm »
hay guys

i'm trying to make my player to Rotate and look at the mouse when i move the mouse.

here is the code

Code: [Select]


//Screen = 800X600

//while loop
{
//while event loop
//{
//}
int PlayerX=SpritePlayer.GetPosition().x;
int PlayerY=SpritePlayer.GetPosition().y;

int MouseX=Game.GetInput().GetMouseX();
int MouseY=Game.GetInput().GetMouseY();

if ((MouseX<=400)&&(MouseY<=300))
SpritePlayer.Rotate(0 * ElapsedTime);

if ((MouseX>400)&&(MouseY<300))
SpritePlayer.Rotate(90* ElapsedTime);

if ((MouseX>400)&&(MouseY>300))
SpritePlayer.Rotate(180 * ElapsedTime);

if ((MouseX<400)&&(MouseY>300))
SpritePlayer.Rotate(270 * ElapsedTime);
}


this is what i though i would do

x=mousex
y=mousey

Why don't you use std::atan2() to compute the correct angle?
