# Why rotateX function not working

I call rotateX, but for some reason it does not work.

All code :

``````function setup()  {
createCanvas( 200, 200, WEBGL);
angle = 0.0; // так тоже работает _angle = 0

my_point_size = 20;
my_layer = 170;
}
function feet() {
R1 = 10;

// первый слой
angle_t1 = 0;

for( i = 0; my_point_size/4>= i; i++)
{
point(R1*cos(angle_t1), R1*sin(angle_t1), 0);
angle_t1 +=(TWO_PI)/(my_point_size/2);
}

R2_x = R1;
R2_y = 0.0;

for( i = 0; my_point_size/4 >= i; i++)
{
R2_y -= R1/2;
point(R2_x, R2_y, 0);
}

angle_t1 -=(TWO_PI)/(my_point_size/2);
for( i = 0; my_point_size/4 >= i; i++)
{
point(R1*cos(angle_t1), R2_y + R1*sin(angle_t1), 0);
angle_t1 +=(TWO_PI)/(my_point_size/2);
}

R2_x = -R1;
for( i = 0; my_point_size/4 >= i; i++)
{
R2_y += R1/2;
point(R2_x, R2_y, 0);
}
}

function legs() {
feet() ;
}

function my_rotate() {
rotateX(angle);
//rotateY(_angle);
//rotateZ(_angle);

angle += 0.1;
}

function draw() {
background(220,220,220, 5);

// rectMode(CENTER); //центритует рисунок
stroke(0, 0, 156, 200);  // даëм точке цвет
strokeWeight(3);          // ширина точки

legs() ; // рисуем
my_rotate(); // крутим
}
``````

Hello,

This has a good description:

Try rotating before the shape and see what happens.

rotate, translate, and scale affect any drawing commands that happen AFTER they are called, so move your `my_rotate();` call to before your `legs();` function call in `draw()`.
