Help with Snow Falling Module

sdetweil

@xTITUS-MAXIMUSx
AND if it happened, you module content is not present at that time
so this will fail
const snowContainer = document.querySelector(“.initial-snow”);

you can debug this by using the developer window sources tab, and put a breakpoint on the code and step thru it…

@sdetweil Thank you for the reply and I really appreciate your help with this. To be honest I had some help with chatGPT as I don’t quite understand JS very well. Can you explain more about what I need to do exactly for this to work? Do I need to take the snowflake.js contents and place them in the MMM-Snowflake.js when it is being registered and use the notificationReceived function? Again, thanks for the help.

@xTITUS-MAXIMUSx yes, you would move the script to the module.js

and then put the function after the notification

one thing tho… this is only happening once… I think… , no… it repeats… cool (edited)

there are snow modules already (don’t mean to bust your bubble)
see the 3rd party list above and enter snow in the search box

NVM I figured it out. Here is what I needed to do. I had to really think about what you were saying. thanks for pointing me in the right direction. I will post this on github for everyone to use.

Module.register("MMM-Snowflakes", {
    defaults: {
        totalSnowflakes: 50 // Default number of snowflakes
    },

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

    // Called when MagicMirror DOM is created
    notificationReceived: function(notification, payload, sender) {
        if (notification === 'MODULE_DOM_CREATED') {
            this.createSnowflakes();
        }
    },

    // Create snowflakes in the DOM
    createSnowflakes: function () {
        const snowContainer = document.querySelector(".initial-snow");
        if (!snowContainer) {
            Log.error("Snowflakes: Container not found!");
            return;
        }

        const totalSnowflakes = this.config.totalSnowflakes; // Get from config
        const snowflakeVariants = ["&#10052;", "&#10053;", "&#10054;"]; // Snowflake symbols

        for (let i = 0; i < totalSnowflakes; i++) {
            const snowflake = document.createElement("span");
            snowflake.classList.add("snowflake");

            // Randomly pick a snowflake variant
            const variantIndex = Math.floor(Math.random() * snowflakeVariants.length);
            snowflake.innerHTML = snowflakeVariants[variantIndex];

            // Randomize size, position, and animation duration
            const size = Math.random() * 0.8 + 0.2; // Size between 0.2 and 1
            const left = Math.random() * 100; // Random horizontal position
            const duration = Math.random() * 5 + 5; // Duration between 5s and 10s
            const blur = Math.random() < 0.3 ? "blur(1px)" : "none";

            snowflake.style.fontSize = `${size}em`;
            snowflake.style.left = `${left}vw`;
            snowflake.style.animationDuration = `${duration}s`;
            snowflake.style.filter = blur;
            snowflake.style.setProperty("--start-x", `${Math.random() * 10 - 5}vw`);
            snowflake.style.setProperty("--end-x", `${Math.random() * 10 - 5}vw`);

            // Append snowflake to the container
            snowContainer.appendChild(snowflake);
        }
    },

    // Generate DOM for this module
    getDom: function() {
        const wrapper = document.createElement("div");
        wrapper.className = "initial-snow"; // Container for snowflakes
        return wrapper;
    },

    // Load CSS for the module
    getStyles: function() {
        return ["MMM-Snowflakes.css"];
    }
});
