Week 5 - Prac B

This week practical we have a discussion about how to use action-script 3.0 to create game in flash, tutor gave us a a website called Lynda  which is quite helpful for coding stuff in action-script 3.0. 

I also found a snake game code through google and I know how to code the snake up/down/left/right direction:

private function directionChanged(e:KeyboardEvent):void

        {

            var m:Object = new Object(); //MARKER OBJECT

            if (e.keyCode == Keyboard.LEFT && last_button_down != e.keyCode && last_button_down != Keyboard.RIGHT)

            {

                snake_vector[0].direction = "L";

                m = {x:snake_vector[0].x, y:snake_vector[0].y, type:"L"};

                last_button_down = Keyboard.LEFT;

            }

            else if (e.keyCode == Keyboard.RIGHT && last_button_down != e.keyCode && last_button_down != Keyboard.LEFT)

            {

                snake_vector[0].direction = "R";

                m = {x:snake_vector[0].x, y:snake_vector[0].y, type:"R"};

                last_button_down = Keyboard.RIGHT;

            }

            else if (e.keyCode == Keyboard.UP && last_button_down != e.keyCode && last_button_down != Keyboard.DOWN)

            {

                snake_vector[0].direction = "U";

                m = {x:snake_vector[0].x, y:snake_vector[0].y, type:"U"};

                last_button_down = Keyboard.UP;

            }

            else if (e.keyCode == Keyboard.DOWN && last_button_down != e.keyCode && last_button_down != Keyboard.UP)

            {

                snake_vector[0].direction = "D";

                m = {x:snake_vector[0].x, y:snake_vector[0].y, type:"D"};

                last_button_down = Keyboard.DOWN;

            }

            markers_vector.push(m);

        }
