Question

so I create a sprite every second at a random position . What I would like is that the sprite is oriented to the center of the screen. For example if I create a human body every second at a random position, I would like his head to be oriented to the center of screen . thank you 🙂 sorry for my english I’m french :/

Answer 1

CCPoint pos1 = [yourHuman position];
CCPoint pos2 = screenCenter;

    float theta = atan((pos1.y-pos2.y)/(pos1.x-pos2.x)) * 180 * 7 /22;

    if(pos1.y - pos2.y > 0)
    {
        if(pos1.x - pos2.x < 0)
        {
            [yourHuman setRotation:(-90-theta)];
        }
        else if(pos1.x - pos2.x > 0)
        {
            [yourHuman setRotation:(90-theta)];
        }       
    }
    else if(pos1.y - pos2.y < 0)
    {
        if(pos1.x - pos2.x < 0)
        {
            [yourHuman setRotation:(270-theta)];
        }
        else if(pos1.x - pos2.x > 0)
        {
            [yourHuman setRotation:(90-theta)];
        }
    }

This is done. Keep this code in a method. And use it.. 🙂 Hope this helps..
