How to host local Club Penguin Private Server (CPPS) on Silicon Mac (M1/M2/M3) thru play.localserver & Solero's Wand install.

I spent so long looking for a solution to this that I want to contribute what worked for me. I got so frustrated looking for something that worked, and I hope this guide will help others avoid that frustration.

This is NOT a guide on hosting or serving a CPPS. This is a guide on making a CPPS playable by locally hosting your server on your Silicon M1/M2/M3 Macbook. This worked on my M3 Macbook, and, in my experience, it seems the newer the hardware/operating system gets, the harder it is accomplish this.

DISCLAIMER *I do not know very much about this topic. I can paste commands into terminal and execute them, I know how to install DMG files I downloaded from the internet (the bar is in hell, I am aware), and I know how to enter play.localhost to run this in a browser. I am no expert; this guide is for beginners like myself who want a CPPS. This is beginner-level stuff. If you want advice or need help hosting, refer to the Wand Github page, Solero's Dash (an actual web-hosting solution for Houdini/Wand), Solero's discord, or, when in doubt, Google it. (I recommend only asking for help in Solero's discord for help AFTER trying your best to search for a solution, and even after that, trying to search key terms in their chat logs. They often have to repeat the same advice over, and over, and over again.)*

TLDR; IDK shit about shit

USING WAND INSTALLER

wand description from github: Wand makes it easy to configure dash, houdini and a media server utilizing docker & docker-compose.

All the assets are located here.

Installation instructions from the above link:

Installation script 1. run the script: bash <(curl -s https://raw.githubusercontent.com/solero/wand/master/install.sh) 2. Answer Questions which are: Database password (Leave blank for random password) Hostname (example: clubpenguin.com) (Leave empty for localhost) External IP Address (Leave empty for localhost) 3. Run and enjoy. Run this command: $ cd wand && sudo docker-compose up

The steps I took:

1. Install Docker via Terminal & Homebrew.

Installing the Docker DMG file did not work properly when I tried. I realized later that Docker is seperate from Docker Desktop (the DMG file). I got Docker to work by using Terminal to install Homebrew, and then using Homebrew to install Docker.

Indented text = paste into Terminal.

Command to install Homebrew:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

Ensure Homebrew is installed:

brew --version

Install Docker:

brew install docker

Recommended: Install Docker Desktop (useful in determining if your server is running, stopped, or stuck in a restart loop).

brew install --cask docker

Run Docker Desktop:

open -a Docker

2. Run installation script:

bash <(curl -s https://raw.githubusercontent.com/solero/wand/master/install.sh)

From Github instructions:

Answer Questions which are:

Database password (Leave blank for random password)

Hostname (example: clubpenguin.com) (Leave empty for localhost)

External IP Address (Leave empty for localhost)

3. $ cd wand && sudo docker-compose up

This is what is provided in the Github. This command didn't work on Mac; I believe it's formatted for Linux OS. Here's how I broke it up and enabled it to run from Mac's Terminal.

Navigate to Wand directory:

cd wand

Double-check if you're in the right directory:

ls

Start Docker container:

docker-compose up

If the above doesn't work, try

docker compose up

or

brew install docker-compose

Takes a second...

Ensure Docker is running:

docker info

If it isn't, open the Docker Desktop application.

*After using compose up, this error may appear:*

WARN[0000] /Users/[user]/wand/docker-compose.yml: the attribute version is obsolete, it will be ignored, please remove it to avoid potential confusion

This is harmless. If you get annoyed by errors, this can be solved by:

nano docker-compose.yml

See Version 3.7 at the top? Delete that line.

Ctrl-X (NOT COMMAND-X) to exit, Y to save, Enter.

PLAY.LOCALHOST

Type http://PLAY.LOCALHOST into a browser.

Create a penguin.

Try logging in that penguin:

This step was agony. I'm not savvy with running obsolete or deprecated software, and, of course, Club Penguin (and Houdini/Wand's assest) uses Flash, which was discontinued, and timebombed by Adobe, in 2021.

I tried Ruffle. Club Penguin Journey uses Ruffle, so why can't I?

Running Ruffle in Firefox:

No luck.

In the Solero discord, they'll direct to this blog post:

This method does not work on Mac M1/M2/M3. The program is "out of date" and you cannot run it. It works on Macbook's running Sonoma and backward. I'm on an M3 running Sequoia.

they'll often post this video in the discord:

In theory, this method should work, and it does for many, but for whatever reason, not on my M3. I tried different versions of Ungoogled, I tried so many different patches of Pepperflash, and it never cooperated. I tried Pepperflash, I tried Fast Patch!, I tried dedicated Flash browsers, running Flash plugins for Pale Moon, Ungoogled, Waterfox, but I could never get past him.

Every time I see this stupid penguin's face I'm filled with rage. But I am going to save you that rage!!!

If you get this method to work, yay! I could not. Maybe I don't know enough about patching, maybe I'm a little tech stupid.

WHAT WORKED: Using a dedicated CPPS desktop application that allows you to plug in a URL.

I give you...

He is your solution, your answer to

I discovered this solution through Solero's Discord, when someone answered a question re: playing online.

Waddle Forever was not what I was looking forever, but I noticed in their credits:

The electron client is originally forked from the Club Penguin Avalanche client. The server is based in solero's works in reverse engineering the Club Penguin server (Houdini server emulator). The media server is also mostly from solero's media servers.

And that's how I found out the solution: Using CPA Client

Download the CPAvalanche Client

It runs Adode Flash x64. Easy peasy.

(the instructions are in Portuguese, but for English users:

Navigate to releases.

And download this one:

Once downloaded, open.

Drag into applications.

Run http://play.localhost through the client:

Open CPAvalanche Client. It will direct you to CPAvalance once loaded, but you're here because you want to play play.localhost.

Navigate to CPAvalanche Client next to your Apple. Click Mudar a URL do Club Penguin.

Press Sim.

URL: http://play.localhost

Ok.

Press Login once the page loads, and...

That's it! No more penguin! Have fun :)

1. Variables

In any programming language, variables are used to store data that can be manipulated or retrieved. C++ is no different. In C++, a variable is a name assigned to a memory location that holds a value.

For example:

cpp

Copy code

int number = 5;

Here, int specifies that the variable number is of type integer, and it holds the value 5.

Types of Variables:

int: Holds integer values.

float: Holds decimal values.

char: Holds a single character.

double: Holds larger decimal values.

bool: Stores true or false values.

Understanding how to declare and use variables is one of the first steps to learning C++ programming. As you continue, you'll see how different data types can interact in a program.

2. Data Types

In C++, every variable must have a data type, which determines what kind of data the variable can store. Common data types in C++ include:

int: Used to store integers (whole numbers).

float: Used to store floating-point numbers (numbers with decimal points).

char: Used to store individual characters.

bool: Used to store boolean values (true or false).

string: Although not a built-in type, the C++ Standard Library provides support for storing text strings.

Here’s an example of a simple program with multiple data types:

cpp

Copy code

int age = 25;

float salary = 45000.50;

char grade = 'A';

bool isEmployed = true;

Choosing the right data type for your variables is essential, as it helps manage memory efficiently and avoid potential bugs.

3. Functions

Functions are blocks of code designed to perform a specific task. In C++, a function can be called multiple times, making your code more modular and reducing redundancy.

A basic C++ function looks like this:

cpp

Copy code

int addNumbers(int a, int b) {

    return a + b;

}

This function addNumbers takes two integer inputs (a and b), adds them, and returns the result. Functions allow you to divide your program into smaller, manageable parts and can be reused throughout the code.

4. Control Structures

Control structures determine the flow of your program based on certain conditions. C++ provides several control structures:

if/else: Used to make decisions in your program.

cpp

Copy code

if (condition) {

    // code to be executed if the condition is true

} else {

    // code to be executed if the condition is false

}

switch: A control statement that allows a variable to be tested for equality against a list of values.

cpp

Copy code

switch(variable) {

    case value1:

        // code to be executed if variable equals value1

        break;

    case value2:

        // code to be executed if variable equals value2

        break;

    default:

        // code to be executed if variable doesn’t match any case

}

for, while, and do-while loops: These loops are used to execute a block of code repeatedly as long as a condition holds true.

Understanding these structures is vital for making decisions and automating repetitive tasks in your program.

5. Objects and Classes

C++ is an object-oriented programming (OOP) language, meaning it relies heavily on objects and classes. An object is a collection of data and functions that act on that data. A class is the blueprint from which objects are created.

Here’s an example of a simple class:

cpp

Copy code

class Car {

    public:

        string brand;

        string model;

        int year;

        void honk() {

            cout << "Beep beep!" << endl;

        }

};

In this class, we have three variables (brand, model, and year), and one function (honk). We can then create objects based on this class:

cpp

Copy code

Car myCar;

myCar.brand = "Toyota";

myCar.model = "Corolla";

myCar.year = 2020;

myCar.honk(); // Output: Beep beep!

OOP allows for the modular and reusable structure of code, making it easier to maintain and extend in the future.

6. Pointers

One of the most unique and powerful features of C++ is pointers. A pointer is a variable that stores the memory address of another variable. Pointers are used in scenarios where direct memory access is needed, such as in dynamic memory allocation or when interacting with hardware.

For example:

cpp

Copy code

int number = 10;

int* ptr = &number;

Here, ptr stores the memory address of number. You can then use this pointer to access or modify the value stored at that memory address.

7. Arrays

Arrays are used to store multiple values of the same type in a single variable, rather than declaring separate variables for each value.

Example:

cpp

Copy code

int numbers[5] = {1, 2, 3, 4, 5};

In this example, numbers is an array that can store five integers. Arrays are essential for handling large data sets efficiently.

8. Standard Template Library (STL)

The Standard Template Library (STL) is a powerful feature of C++ that provides a set of commonly used data structures and algorithms. It includes:

Vectors: A dynamic array that can grow or shrink in size.

Stacks: A container that follows the Last In First Out (LIFO) principle.

Queues: A container that follows the First In First Out (FIFO) principle.

Maps: A collection of key-value pairs.

STL makes C++ programming faster and easier, as you don’t have to write common data structures and algorithms from scratch.

So I've veen obsessed with Cake Sort game I recently tried. It is basically ads and a bit of a game, as most of these, sadly. I tried some others, but they are not all that similar. Surprisingly there wa only one pizza sort game like this��

I got curious about the mechanics of it to get why it is so addictive. It is similar to color sort games and tetris versions, but different.

Is it like sudoku, perhaps? Is it similar to chess etc as well🤔 What else can it be applied for/reskinned as, aside pizza and cakes?

I think it can be a cute mini game/ puzzle for regular game.

I'm gonna try to write a pseudocode, and if it us not totally out of my usual experiments with Unreal, I'd love to make a blueprint sample of this.

And here is a view from other game that helps with the basics understanding:

Basically, you need to place the cakes in a position of 2x2, if you have a cake of that type lready. If not, place elsewhere. Also the first game has double plates, so need to account for it.

I am tempted to but the first one (i swear it isn't an ad lol). The game can be played endlessly, if you are careful (you seem to be offered cake plates you can use). You can reset and start over. But there are also tools to destroy or move cakes, which can be essential to endless play.

Pseudocode related:

Wiki articles always have useful stuff

Karel - Karel is an educational programming language for beginners. Stanford University resource with interactive introductory course & youtube lections. A version of pseudocode, that helps to learn programming principles. Is online for free in multiple languages.

some other stuff i found and will try while working on this:

EZ Pcode - This tool is intended to help teachers prepare Pseudocode that is consistent with the new IB Computer Science standards for the 2014 syllabus

smth on chinese

I ued to try programming on ipad (need to look up the apps, will get back to it when i get ipad mini to replace my current one), and wrote some pseudocode as well as worked on cpp online. Diagrams to do algorythms are quite similar to what ends up being a lbueprint in Unreal Engine. So, process of game making:

make a diagram of the mechanics (visual representation)

turn it into pseudocode

use blueprints/language to convert it into interactive thing

12:55pm Ok. i tried. overall, even while playing I already saw the game is hella complex. There is just a ton of little things to think thorugh, even tohugh it is also quite easy to comprehend for writing the code from scratch, compared to something like trying codingame

There are a lot of things to consider, setting aside the whole visual part. But this is another smallish project i want to explore as a studying material. It is more basic game and fits learning principles of programming better than "original idea survival game.... idea i just got vaguely written down,.... happy accidents" type of projects i've been on.
