How to sync with the cycles?

[fabkury]

I see in the rain.js script that I can spawn a thread and use delay() to make changes over time.

Would there be a way to make changes in sync with the cycles? For example, have function foo() get called at every cycle.

My goal is to synchronize Sand Game 2 with the frames of an external animated GIF.

Here is another example of the kind of thing I am creating with your software:

(to see the very simple animation you need to click on the image)

I always credit your name and specify the link to your repo. This is how it looks like:

If you prefer me to credit you in some other way, please let me know.

This is posted on my profile in the Divoom app. To find me there, just search for user "Fab". It's all free, just for fun.

Thanks again for the nice software.

Unfortunatelly, this is not possible through scripting. Changes to the Java codebase would be required to create and expose such API functions. And then rebuild the app using Maven...

But such things are easy to do in Sand Game JS. Few examples that can be executed in browser console:

// spawn fire after each iteration = fire source
sandGame.addOnProcessed(() => {
    sandGame.graphics().drawRectangle(60, 50, 100, 55, brushes.fire);
});

// bigger fire
sandGame.addOnProcessed(() => {
    sandGame.graphics().drawRectangle(120, 50, 170, 55, brushes.fire);
    sandGame.graphics().drawRectangle(120, 50, 170, 55, brushes.effect_temp_255);
});

// control processing manually
sandGame.stopProcessing();
for (let i =0; i < 1000; i++) {
    sandGame.doProcessing();  // perform one iteration now
}
sandGame.startProcessing();

Thanks a lot for the detailed answer! The closest I could get in Sand Game 2 (to running a function at every cycle) was to try to match the frames per second of Sand Game 2 with the delay length. E.g. 25fps = 40 ms delay per frame, i.e. per call to foo(). It kind of worked, but sometimes would flicker. Still usable but I should check this new approach with Sand Game JS 👍 Thanks for all the attention.

No problem at all

You gave me the idea that I could try to make some gifs of Sand Game JS gameplay and it turned out that it would be easy to add a recording tool directly to the dev tools, so I did it. You can try it here. Record (start/stop) button creates a zip file with png frames...

😱 wow thanks a lot!!

Let me show you something cool.

That flaming sword I made with SG2, another user in Divoom liked it and asked if his signature character, Kickling, could try to wield it.

He's a young boy (maybe pre-teen? I don't know) from somewhere in Europe. It was so much fun! 🙂

If you decide to go there in the Divoom app, you could say hello to him 👍🙂

thanks for the fun 👍👍

Cool, I will check your profile :)
