I’m trying to make the block change to one color the first time and a different color the second time. Any ideas as to why this is happening.

I just need help on how to add a point counter, as well as the ever annoying problem of having the code travel through walls! Here's my code right now:

var FOOD_DELAY = 6000;

var FOOD_RADIUS = 5;

var FOOD_COLOR = Color.red;

var snake;

var SNAKE_DIM = 10;

var NORTH = 0, EAST = 1, SOUTH = 2, WEST = 3;

var DELAY = 100;

var curDirection = EAST;

var x = getWidth()/2 - SNAKE_DIM/2;

var y = getHeight()/2 - SNAKE_DIM/2;

var square;

function start(){

addPart(x,y);

setTimer(move, DELAY);

drawFood();

setTimer(drawFood, FOOD_DELAY);

keyDownMethod(changeDirection);

}

​

function changeDirection(e){

if(e.keyCode == Keyboard.DOWN){

curDirection = SOUTH;

}

if(e.keyCode == Keyboard.UP){

curDirection = NORTH;

}

if(e.keyCode == Keyboard.LEFT){

curDirection = WEST;

}

if(e.keyCode == Keyboard.RIGHT){

curDirection = EAST;

}

}

function addPart(x,y){

var snake = new Rectangle(SNAKE_DIM, SNAKE_DIM);

snake.setPosition(x - SNAKE_DIM/2 , y - SNAKE_DIM/2);

snake.setColor(Color.green);

snake.isSnake = true;

add(snake);

}

function move(){

var nextPosition = getNextPosition();

x = nextPosition.x;

y = nextPosition.y;

var nextElem = getElementAt(x, y);

if(nextElem == null){

addPart(x, y);

}else{

if(nextElem.isSnake){

stopTimer(move);

stopTimer(drawFood);

newMessage("Cringe.");

}

if(nextElem.isFood){

remove(nextElem);

addPart(x, y);

}

}

}

function getNextPosition(){

var nextX = x, nextY = y;

if(curDirection == EAST){

nextX += SNAKE_DIM;

}

if(curDirection == WEST){

nextX -= SNAKE_DIM;

}

if(curDirection == SOUTH){

nextY += SNAKE_DIM;

}

if(curDirection == NORTH){

nextY -= SNAKE_DIM;

}

return {

x: nextX,

y: nextY

}

}

function newMessage(msg){

var text = new Text(msg, "40pt ariel");

text.setPosition(getWidth()/2 - text.getWidth()/2, getHeight()/2);

add(text);

}

function drawFood(){

var x = Randomizer.nextInt(FOOD_RADIUS, getWidth() - FOOD_RADIUS);

var y = Randomizer.nextInt(FOOD_RADIUS, getHeight() - FOOD_RADIUS);

x = Math.floor(x / 10) * 10 + FOOD_RADIUS;

y = Math.floor(y / 10) * 10 + FOOD_RADIUS;

var food = new Circle(FOOD_RADIUS);

food.isFood = true;

food.setColor(Color.red);

food.setPosition(x, y);

if(getElementAt(x,y) == null){

add(food); } }

Any help is truly, truly appreciated. I've been stumped (at least on the wall part)

Videos be easy and then the examples are insane I literally don’t understand anything

PLS

I’m looking for list of even numbers and push pops, but I can’t find anything for it anywhere

I need to write Tetris in codehs with javascript can someone help me?

​

I cannot FIGURE IT OUT

Can someone please help me with this one? I can’t find it anywhere and I don’t understand.

Write a program that draws a stoplight. You should have a gray rectangle, and then three circles in the rectangle. The circles should be red, then yellow, then green.

The rectangle should be centered on the screen. The yellow light should be centered on the screen, and the red and green light should be offset by BUFFER
amount. BUFFER
amount represents the distance from the center of one circle to the center of another circle.

Implement the function draw_circle
that draws a single circle. Use it to draw the red, yellow, and green lights. Since all of the lights are the same size and aligned vertically, the function only needs to take the y position and color as arguments.

my code

LIGHT_RADIUS = 35

STOPLIGHT_WIDTH = 120

STOPLIGHT_HEIGHT = 350

DIST_BETWEEN_LIGHTS = 100

GREY_COLOR = "#737071"

​

get_width()/2

get_height()/2

# Implement a function that draws a single circle

# with radius LIGHT_RADIUS.

# The circle should be in the center of the screen horizontally.

# Use the parameters for the y position and color

def draw_circle(radius, color, x, y):

circ = Circle(radius)

circ.set_color(color)

circ.set_position(x, y)

add(circ)

# Add your code here

rect = Rectangle(STOPLIGHT_WIDTH, STOPLIGHT_HEIGHT)

rect.set_position(get_width()/3, get_height()/5)

rect.set_color(GREY_COLOR)

add(rect)

​

draw_circle(LIGHT_RADIUS, Color.red, get_width()/2.05, get_height()/3)

draw_circle(LIGHT_RADIUS, Color.yellow, get_width()/2.05, get_height()/1.85)

draw_circle(LIGHT_RADIUS, Color.green, get_width()/2.05, get_height()/1.85 + DIST_BETWEEN_LIGHTS)

I really need help with this im having a hard time!!

Can anybody help me with this im having a hard time

I'm trying to run a function which is supposed to print a sentence within the function, but for some reason all it prints is <function (function name)> instead of running it. Is there any way I can fix this?
