While looking to do some experiments with device motion data in HTML5, I found that there were no existing demos that would work on iOS 14. So, having spent a few hours figuring it out, I decided to write a tutorial with an up-to-date demo.

While developing HTML5 games using GameMaker Studio, it may eventually come to your attention that the game does not render at native resolution, depending on the device, looking variously blurry as result. This small post is about fixing that.
Continue readingOn some occasions you may want to open a link in a new tab a GameMaker' HTML5 game.
As simple as it may look, this presents a bit of a problem:
url_open_ext is by far the most convenient of these, so let me explain why that does not work:
To prevent any page from being able to randomly open indefinitely large quantities of new tabs, the browser will automatically block attempts to open new tabs\windows unless they originate from user interaction (click event);
GameMaker handles events, and writes down new input states to later dispatch GML-level events at the right time and place (see event order). This means that your GML code inside a "Mouse Pressed" event does not count as originating from a user interaction (as it executes a few milliseconds later), and thus is not allowed to open new tabs (and do some other things).
However, with a bit of JS (and understanding of internal workings of GM), it is possible to accomplish the intended result, and this post is about that.

Mouseover to view animation (note: mild color cycling)
A year and some ago, I published an extension that allows to use custom logos for HTML5 games made with GameMaker: Studio. Since some functionality has been added since then, I made an updated version with more options.

For a little while now, I was working on a new thing - a program that would allow to test GameMaker code right in your browser. It is now complete, published, and is pretty cool.
You can either check it out right now or continue reading for development details and a bunch of demonstrations of it in action.

I made a small GameMaker: Studio extension that provides a unified API for "mouselock" between desktop and web (HTML5).
The way this works is by utilizing built-in mouse snapping functions on desktop targets, and using Pointer Lock API on HTML5. It bridges between the two, and you get simple functions like mouse_lock(), mouse_unlock(), and mouse_delta_x & mouse_delta_y for getting the mouse movement offset while mouse is locked.
So, if you ever wanted to make some web-based first-person shooters (or just games with mouselook) with GameMaker: Studio, now you can.
The extension is free and can be downloaded from itch.io or GameMaker: Marketplace.
(or see by yourself here)
Someone on forums has asked if there's an example/extension that would allow to display a logo or image alongside with the loading bar in HTML5 module of GameMaker: Studio, and I did just that.

Being able to quickly upload a HTML5 game to the web is important.
It's not just a more comfortable format for sharing, but sometimes a requirement, since games created with GameMaker: Studio, Construct 2, Haxe+OpenFL and many other tools may not necessarily fully function when launched locally due to browsers laying restrictions over local file access (meaning that sending a ZIP with game files may not quite work).
While it used to be possible to host HTML5 games on Dropbox for free (or, rather, it still is possible, but only if you have enabled the public folder before the late 2013, else it'll cost you some), you can still host HTML5 games freely on Google Drive.
And this article explains the process of hosting your games on Google Drive in detail.

This is only a small thing out of everything I need to make/finish/release in next months, but...
So there is now multi-touch support in openfl-bitfive, which is an alternative OpenFL HTML5 backend with focus on blitting and compatibility across platforms.
Usage is identical to Flash/AIR - you add an according event listener to your desired DisplayObject, and handle the TouchEvent objects it catches:
stage.addEventListener(TouchEvent.TOUCH_BEGIN, function(e) { trace("Touched at (" + e.stageX + ", " + e.stageY + ")"); });And, same as it goes for mouse events, the rest is handled behind the scenes - events are routed automatically, and you don't need to worry about browsers and devices with partial or glitchy support.
Addition is already live at both repository and haxelib, there's a demo available (probably want to view it from mobile device), and this post contains some extra details on what it took.
Also, if you needed this for some time, you can pretty much thank Ozdy (which is also the largest supporter of backend) for suggesting the feature.
For me this morning started with just another bit of code, some of which has granted BitmapData.noise() function support for my OpenFL backend OpenFL-bitfive, proven to be a more interesting process than expected, and, given that it's otherwise hard to tell what I am working on, I thought that I could write a post about this:
