Flash Cartesian Coordinate

First know that Flash Cartesian coordinate with four separate coordinate for each side. Basically Cartesian coordinate likes a flash root timeline. It will always start in the upper left hand corner on the root timeline. The top left corner in flash the X,Y coordinates is (0,0).

Flash coordinates represent position of WIDTH along the x axis and HEIGHT along the y axis

Flash coordinate represent positions of width along the X axis and Height along the Y axis.

Create a movie clip.

Draw 16X16 rectangle and make center align.

Make a Instance Name "Player".

Add key listener

on(KeyPress "<Left>"){
// Define _x axis movement.
/*The _x coordinate of a movie clip, relative to the local coordinates of the parent movie clip. Its coordinate system refers to the upper-left corner of the stage as (0,0).*/
//The width of the movie clip in pixels.
	if(player. _x>(player._width/2)){
	player. _x - =5;
     }
}
 
on(keyPress "<Down>"){
	if(player._x<(172-(player._width/2))){
		player._x +=5;
     }
}
 
on(keyPress "<Up>"){
// Define _y axis movement.
	if(player._y>(3+(player._width/2))){
		player._y -=5;
    }
}
 
on(keyPress "<Down>"){
	if(player._y<(203-(player._width/2))){
		player._y +=5;
    }
}
