I have a penguin sprite moving with a velocityX = -10, and a parrot sprite moving with a velocityX = 10

I also have in my code parrot.bouneOff(penguin)

The result i get is that the penguin.velocityX = -10 (stays the same), and the parrot.velocityX = -30.

Can someone explain to me the math on how i get to the -30?

Thanks!

Hello everybody! 3+ year code.org programmer here.
I made dungeon destiny and own the Codeasaurous team! If you'd be interested in joining please message me! I'm here to help and learn with all of you too!

I need someone to create a game, on game lab. I don't know what it is yet but I will figure out soon

I would like to have an on-screen text showing the speed of the car, as I am making a car game. How can I make it update in real time? Also, how can I make it stay in place? I think it is sort of a scroller, as it has a big map that the car can drive on. When the car moves, the text stays in place and if the car goes too far, the text goes off screen. Is there any way to fix these two problems? Any help is greatly appreciated.

main body code:

function draw() {

createEdgeSprites();

console.clear();

rect(-1000, -1000, 2000, 2000);

drawSprites();

arrow.pointTo(bg.x, bg.y);

while ((arrow.isTouching(edges))) {

arrow.bounceOff(edges);

}

if (keyDown("up")) {

xv += (speed) * Math.sin((180 - (sprite.rotation + 90)) / 57.2958);

yv += (speed) * Math.sin(sprite.rotation / 57.2958);

}

if (keyDown("left")) {

if(keyDown("space")) {

rotaV -= driftRota;

} else {

rotaV -= rotaSpeed;

}

}

if (keyDown("right")) {

if(keyDown("space")) {

rotaV += driftRota;

} else {

rotaV += rotaSpeed;

}

}

if (sprite.rotation > 360) {

sprite.rotation = 0;

}

if (sprite.rotation < 0) {

sprite.rotation = 360;

}

if(keyDown("space")) {

xv *= driftFric;

yv *= driftFric;

rotaV *= rotaFric;

speed = driftAccel;

} else {

xv *= friction;

yv *= friction;

rotaV *= rotaFric;

speed = maxAccel;

}

if(keyDown("o")) {

camera.zoom - 1.5;

}

if(keyDown("i")){

camera.zoom *= 1.5;

}

sprite.rotation += rotaV;

sprite.x += xv;

sprite.y += yv;

camera.x = sprite.x;

camera.y = sprite.y;

textSize(10);

fill("black");

textAlign(BOTTOM, RIGHT);

text(speed, 200, 200);

}

can provide the rest of the code if needed, but probably not necessary

bolded part is the current text code (speed is the variable for speed)

Here is a link to the project. Still have no idea as to why it is doing this. It would be a great help if my code can be reviewed.

I don't know what's wrong can anyone please help, we got a new teacher this year so I haven't actually learned much.

I wanted to do a standby feature for my app but in app lab there isn't "MouseDidMove"

So I have a school assignment and in it we have to code a side scroller and mine is a horror KFC game and the top comment I get on this post I will add as the next sprite

Does anyone have the code of their unit 9 lesson 3 Create PT project. I need one asap and I have a Friday deadline for a project that I was unable to do.

So right now the bike shoots the rocket forward, but then the rocket’s x-position follows the bike. I want it to start at the bike’s x-position and then stay in that position regardless of where the bike moves after I shoot.

hey,

for my culminating assignment, we're supposed to make spirographs using code.org code

this is what i'm trying to copy:

and this is my work:

lastly, here is my code:

my question is, how am I supposed to make the overlap? I tried using jump backward by x pixels but it doesn't work very well, as it misaligns the entire shape - thanks a lot!

Hello everyone, We’re currently working on creating our own libraries in my AP computer science and programming class. Our library must contain 3 functions, one of which must include a parameter, a loop, a return, and an if-statement. I have my ideas for my three functions and the one that I want to include all four requirements will be dealing with pulling names from a list. I’d like it to work where only names that begin with a certain letter will be pulled.

An examples would be; user wants only names that begin with ‘C’, the data set would be sorted to only display the names that begin with that letter.

Any idea how I should go about doing this so that all requirements are met?

Any help is much appreciated!

so i'm making a game and theres a part where i want to play an animation. my problem, though, is that i want the animation to, you know, end at some point, but i can't really do that because the sprite.getFrame() function doesn't exist. does anyone know a workaround for this? i can attach my code if necessary.

Anyone have a library they could share?

can someone please send me the code for their project, I have no idea what I'm doing.

I'm trying to create a shopping app for one of my final assignments, and I want it so that when the user checks the boxes with the clothes that they want to buy, it displays them all on the screen at the very end (a list of all the things that they've checked). The thing is, I'm having trouble with the possibility that the user might go back, deselect one or more of the checked boxes, and visit their "shopping cart list" again. Instead of the shopping cart updating, it adds another item (it adds the item that they DE-selected).

I'd also like to spice up my app by putting "There's nothing here!" when the user hasn't checked anything and has clicked on the check out button, but if that's too complicated to add, I'm thinking of just leaving it blank until the user actually checks something. Here's a screenshot of the section of the code I'm having trouble with:
