Need Some Math Help Please

[xhunterko]

So I'm fiddling with my weapon code and I have it set to where you hold down the key and it circles the player. Which is nice and an attack I want. However, I noticed that when I told it to justPress a key, the weapon did not circle. Instead, it exhibited a yo yo like behavior. I thought nothing of it until I wanted another attack, which is just that. However, it yo yos in a random direction each time, and I want it to simply yo yo in one of the cardinal directions depending on where the character is facing.

So how do I do that mathematically?

This is what I'm doing so far:

if (FlxG.keys.justPressed.C)
        {
            stretchingHook();
            stretching = true;
           
            radius = 0;
            ang = 0;            
        } else
        {
            followPlayer();
            ang = 48;
            radius = 0;
        }
       
        if (FlxG.keys.pressed.Z        
            #if !FLX_NO_GAMEPAD
            #if OUYA
            || gamepad.pressed(OUYAButtonID.U))
            #else
            || gamepad.pressed(XboxButtonID.X))
            #end
            #else) #end
        {
           
            radius = 48;
            ang = 0;
           
            circlePlayer();
            circliing = true;
        }
        else
        {    
           
            followPlayer();
        }

circlePlayer

    private function circlePlayer(Acceleration:Float = 4):Void
    {    
        circliing = true;
        this.x = _player.x + radius * Math.cos(ang);
        this.y = _player.y + radius * Math.sin(ang);
        ang += speed * FlxG.elapsed; //you can multiply this to FlxG.elapsed to have a constant velocity
        //you can reset ang to 0 whent it i over than 360
       
    }

stretchingHook is the same as circlePlayer except on call.

So how can I get it to act like a yo yo?

Using 3.x.x.

Just modify your circlePlayer function so that it's the radius that changes and ang is  where the player is facing.

That worked! Thanks! ^^
