Example #1

void SDLCanvas::drawProjectile(Projectile& pro, Color& c) {
	if(!isDrawProjectilesEnabled())
		return;

	Vector2D trail = pro.loc_;
    if(scale_ < 0.013)
    	trail += pro.getDirection() * -1500;
    else
    	trail += pro.getDirection() * -500;

    drawLine(trail.x_,trail.y_, pro.loc_.x_, pro.loc_.y_, c);
}
