MMM-Fireworks

[chrisfr1976]

Hello,

a short update since time is running out :)

I’ve modified the code a little. In my set up I had some performance problems with the animation.

So I put all other modules in the “Hide” during the animation is running. Afterwards everything will come back (so the plan).

I don’t know if everybody likes or needs this. So I show the modified code just here.

Replace the complete code in “MMM-Fireworks.js” with this:

Module.register("MMM-Fireworks", {
    defaults: {
        startDateTime: "2024-12-31T23:59:00", // ISO format
        duration: 60000, // Duration in milliseconds
    },

    start: function () {
        this.fireworksActive = false;
    },

    getDom: function () {
        const wrapper = document.createElement("div");
        wrapper.id = "fireworksContainer";
        return wrapper;
    },

    notificationReceived: function (notification, payload, sender) {
        if (notification === "DOM_OBJECTS_CREATED") {
            this.scheduleFireworks();
        }
    },

    scheduleFireworks: function () {
        const startTime = new Date(this.config.startDateTime).getTime();
        const currentTime = Date.now();
        const delay = startTime - currentTime;

        if (delay > 0) {
            setTimeout(() => this.startFireworks(), delay);
        } else {
            console.warn("Fireworks start time has already passed.");
        }
    },

    startFireworks: function () {
        this.fireworksActive = true;
        const container = document.getElementById("fireworksContainer");
        container.classList.add("fullscreen");

        const canvas = document.createElement("canvas");
        canvas.id = "fireworksCanvas";
        container.appendChild(canvas);

        this.sendNotificationToModules("HIDE"); // Module ausblenden

        const fireworks = new Fireworks(canvas);
        fireworks.start();

        setTimeout(() => {
            this.stopFireworks(fireworks, container);
        }, this.config.duration);
    },

    stopFireworks: function (fireworks, container) {
        fireworks.stop();
        container.innerHTML = ""; // Clear the canvas
        this.fireworksActive = false;
        this.sendNotificationToModules("SHOW"); // Module wieder einblenden
    },

    sendNotificationToModules: function (action) {
        MM.getModules().enumerate((module) => {
            if (module.name !== "MMM-Fireworks") {
                if (action === "HIDE") {
                    module.hide(500); // Mit Animation ausblenden
                } else if (action === "SHOW") {
                    module.show(500); // Mit Animation einblenden
                }
            }
        });
    },

    getStyles: function () {
        return ["MMM-Fireworks.css"];
    },

    getScripts: function () {
        return ["fireworks.js"];
    }
});

Party on!

Cheers Chris.

Hello,

unfortunately even more optimizations were necessary. So I update the repository.

New:

• hides all modules during animation
• suspends all modules during animation

Reduced effects:

createExplosion(x, y) {
        const particleCount = 25; // was 50

this.particles.forEach((p) => {
            p.x += p.vx;
            p.y += p.vy;
            p.vy += 0.01; // less gravity
            p.alpha -= 0.01;
        });

    setup() {
        this.canvas.width = this.width*0.95 //reduced width 
        this.canvas.height = this.height*0.95 //reduced height
        window.addEventListener("resize", () => this.resize());
    }

• And updated CSS to be in the middle of the screen again.

Hopefully you’ll celebrate this, too!

Worked for me earlier when I tested it this afternoon.
Nice module…

Hello!

great idea, you module !

but does it really work ? it does not appear on my mirror, after installing it.

Can you please re-check on your side ?

Thanks in advance and have a good evening,

Cédric

[sdetweil]

@com1cedric what position did you set it to?

[chrisfr1976]

@com1cedric see my answer on GitHub. It only starts if the start time is exactly now or in the future.

[sdetweil]

@chrisfr1976 why would you want it in the past?

oh, and NOW is impossible to catch

[chrisfr1976]

@sdetweil no, the start time is relevant. If the start time is in the past and the effect time may be stll okay like 3652460601000, the effect does not start. This could be the problem here. So you really need to wait for the defined time in the config.
I‘ve spent several minutes with waiting….

[sdetweil]

@chrisfr1976 if the start time is in the past and the event time is in the future, then the start time should be now. (however that gets calculated, literal or adjusted offset…)

I am not looking at the doc or code

I have completely reworked the MMM-Fireworks module!

New:

• It is now using the p5.js library. So it is now faster and I’ve added more config options.
• Also the timing problem ist solved. You can define a start date and time. If you need to restart your mm inbetween it continues.
• you can install it today and enjoy on next new years eve. (The JavaScript’s setTimeout is solved here (has a maximum delay roughly 2³¹–1 milliseconds - only 24.8 days)
• Added a text overlay
• runs as before in fullscreen but also “in a box” as every other module
• And the best: the explosion effect is now really nice!

@chrisfr1976 Hi,
maybe interesting also for others: There is a canvas opacity parameter set now. So you can can keep all your stuff visible in the background while the fireworks is dancing on your mirror. I didn’t had this feature in mind, but I got this request on GitHub. I like that, too ;-)

A picture from my playground to explain what I mean:

[chrisfr1976]

Hi,
I’ve just released an update to solve several requests and problems.

https://github.com/ChrisF1976/MMM-Fireworks

• Multiple Scheduled Events:
  • The module now accepts an array of scheduled events (each with its own start time and text message). At each event time, the fireworks start with the corresponding overlay text.
• Two separate notifications have been added:
  • NotificationStart (e.g. “FireFireFire”) starts the fireworks immediately using either the notification’s payload text or a default (textNotification).
  • NotificationStop (e.g. “StopFire”) stops the fireworks immediately if they are running.
  • When a notification is received, it overrides the scheduled events temporarily without affecting future scheduled shows.

See also updated config!

You can test the notifications with this simple module. I used it during development. I created a small start and stop button you can use.
If you want to test the notification sender module you need to change the “fullscreen_above” to any other region of the mirror. Otherwise you cannot click on the buttons because they’re “behind” the MMM-Fireworks module…

Config:

{
  module: "MMM-NotificationSender",
  position: "top_left",
  config: {
    startNotification: "FireFireFire",
    stopNotification: "StopFire",
    startText: "Test me!", //leave blank to use text from MMM-Fireworks
    stopText: "Stop Fire", //nothing happens currently - maybe not needed
  }
},

Module:

Module.register("MMM-NotificationSender", {
  // Default configuration options. These can be overwritten in config.js.
  defaults: {
    // Notification names to send. Other modules can listen to these names.
    startNotification: "START_NOTIFICATION",
    stopNotification: "STOP_NOTIFICATION",
    // Text payloads for the notifications.
    startText: "This is a start notification.",
    stopText: "This is a stop notification."
  },

  // Called when the module is started
  start: function() {
    Log.info("Starting module: " + this.name);
  },

  // Override the getDom method to create your custom UI.
  getDom: function() {
    // Create a wrapper element to contain the buttons.
    var wrapper = document.createElement("div");
    wrapper.style.textAlign = "center";

    // Create the Start button
    var startBtn = document.createElement("button");
    startBtn.innerHTML = "Start";
    startBtn.style.marginRight = "10px";
    startBtn.addEventListener("click", this.sendStartNotification.bind(this));
    wrapper.appendChild(startBtn);

    // Create the Stop button
    var stopBtn = document.createElement("button");
    stopBtn.innerHTML = "Stop";
    stopBtn.addEventListener("click", this.sendStopNotification.bind(this));
    wrapper.appendChild(stopBtn);

    return wrapper;
  },

  // Function to send the start notification
  sendStartNotification: function() {
    // Log to console and MagicMirror logs to check the button click event.
    console.log("Start button pressed. Sending start notification...");
    Log.info(
      "Sending start notification: " +
        this.config.startNotification +
        " with payload: " +
        JSON.stringify({ text: this.config.startText })
    );

    // Send the notification with the configured name and payload.
    this.sendNotification(this.config.startNotification, { text: this.config.startText });
  },

  // Function to send the stop notification
  sendStopNotification: function() {
    // Log to console and MagicMirror logs to check the button click event.
    console.log("Stop button pressed. Sending stop notification...");
    Log.info(
      "Sending stop notification: " +
        this.config.stopNotification +
        " with payload: " +
        JSON.stringify({ text: this.config.stopText })
    );

    // Send the notification with the configured name and payload.
    this.sendNotification(this.config.stopNotification, { text: this.config.stopText });
  }
});

@chrisfr1976 Thanks for this. I installed it in April when we were selling our house and used it as a welcome sign when people came through. Question for you: would you be able to make it so we can put in just a month and day for a start date? I was hoping to put in a list of birthdays and not have to remember to change the year.
