so what is wrong?

so how do i make it move left up and down!!!?

well 38 for up, 37 for left, and 40 for down

You can use FRONT, LEFT and UP, DOWN instead: 

if (keyIsPressed && keyCode === RIGHT){ };

I got it for you. its simple. Just find the keycode numbers and dif vars

var x = 30;
var y = 200;

var speed = 0;

draw = function(){

ellipse(x, y, 40, 40);

if (keyIsPressed && keyCode === 39){

x = x +1;

}
if (keyIsPressed && keyCode === 37){

x = x -1;

}
if (keyIsPressed && keyCode === 38){

y = y -1;

}
if (keyIsPressed && keyCode === 40){

y = y +1;

}

};

how can you do it with WASD?

as in:

up: w

left: a

down: s

right: d
