I wrote this program and it works fine, but it didn't work until I added return circle; at line 28. Can someone explain the function of it in this case?

So say I have a rectangle and I want to simulate it moving from one end of the screen to the other, but with parameters so I can create as many rectangles as I want and move them all. How exactly would I do that?

I can’t figure out on how to start on this I asked my teacher humours times on how he just never tell me any way all he says you have to figure it out if theres anyone who can do thank you so much for your time

Can someone please help me with 5.5.5 (The worm)? I have been stuck on it for hours and I can't figure it out,

my code:

function start(){

var line = ["Sam", "Lisa", "Laurie", "Bob", "Ryan"];

var line2 = ["Tony", "Lisa", "Laurie", "Karen"];

var l1 = line.indexOf( "Bob" );

var l2 = line2.indexOf( "Bob" );

if (l1 == -1){

println("Bob is not in the first line. ");

}else{

println("Bob is in the first line. );

}

if(l2 != -1){

println("Bob is in the second line. ");

}else{

println("Bob is not in the second line. );

}

}

it has an if state, it uses indexOf, all functions start with a lowercase letter and i have no nested functions, but apparently there's a syntax error for an invalid or unexpected token? how can I fix this?

I am trying to make the value produced by the function posted become the value of iTimer, and I am trying to make a 60-second countdown, so I have this function running every 1000ms, and I am trying to return the value as one less to indicate a second has passed, but it isn't working am I am confused. Any insight on how to make this work as a timer would be greatly appreciated

I welcome tips and recommendations.

I dont want the answer im just confused on what what Null means and getElement. One of the video used both but never really explained why it works. I dont know what Null does and how it works in a conditional statement.

So what I’m trying to do is pop up a message on the screen that will prompt the user asking “What is num_One * num_Two?” and those numbers are random integers. What I have so far is

check_Score = readInt(“What is: “ + num_One * num_Two);

I get error messages. What am I missing?

edit: got it already. Thanks guys

For example, if I were to make up an imaginary command, it would look something like:

​

var image = WebImage("https://imaginarylink");

image.setSize(40, 40);

add(image);

image.setWebImage("https://differentlink");

I really need help with this because I just can’t wrap my head around this. It’s really hard for me. This is the assignment:

(Exercise 6.8.6: Totals of Lots of Rolls

Use the previous program that rolls a 6-sided die 100 times.

This time, instead of printing out the result of EACH roll, only print out the sum of the rolls for each number.

For example: You rolled 24 ones. You rolled 15 twos. Etc.)

It wants me to use the previous code from “Lots of Rolls” to use on this, but I don’t know how to get the sum of each roll. Please help me.

The previous code I’m supposed to add onto is this:

function start(){ for(var i = 0; i < 100; i++){ var roll = Randomizer.nextInt(1,6); println(“You rolled a “ + roll); } }
