This post about the issues with GameMaker's built-in JSON functions and an extension I made to address the issues.Continue reading
On 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 opens links in the same tab.
- url_open_ext can open links in a new tab, but triggers popup blocker.
clickables can open links in a new tab, but have to be repositioned manually.
(particularly inconvenient if scaling-positioning the game for mobile browsers)
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.Continue reading
This post is about modifying configuration files for Wacom drivers to have a Wacom One tablet function in portrait orientation despite the option not being exposed in configuration UI.
Update: apparently the same applies to Intuos and Bamboo product lines, likely for the entire "generation" of tablets using the same drivers.Continue reading

TweetDeck can play GIFs for a while now. That's nice. It does, however, automatically start playing them as soon as they are in view. That's less nice, especially if you have multiple columns on a large screen - distraction ensued.
Original Spelunky's source code is available for download for a while now.
The downloadable project is, however, in GM8 format, and does not easily work in GMS.
At the same time, a GameMaker:Studio-compatible (ported) version of Spelunky Classic was included in Humble GameMaker Bundle, and thus available to anyone that bought the bundle.
A certain problem with that is, obviously, that if you haven't had the luck to be made aware of and buy the bundle in time, you would not have access to it afterwards.
However, I was able to confirm that the GMS version of Spelunky Classic included in the bundle can in fact be distributed publicly (because the GM8 one already is publicly available), so here's that:
Keep in mind, however, that this the exact file made available via Humble - it may still have some oddities that you'd need to resolve. Regardless, a solid starting point.
For discussions, check out the official forums. Have fun!
Yesterday I made a GameMaker: Studio extension that provides a bunch of utility functions:
- Allows to minimize/maximize/restore the window on demand.
- Allows to disable/enable minimize button, maximize button, close button, and window movement.
- Allows to override behavior for when minimize/maximize/close buttons are clicked.
It is available for free via itch.io; Some examples of uses follow.Continue reading
Mouseover to activate, click to reposition the clipping star.
This is a tutorial about pretty much everything related to clipping drawn graphics in GameMaker.
That is, having drawn graphics only display inside a certain ("clip") area, be that a rectangle (UI regions, minimaps, etc.), circle, or a completely arbitrary shape (pictured above).
Also I'm trying new things so this post is nicely stuffed with interactive demos and snippets.Continue reading
This is a post about implementing homing missiles in GameMaker.
A homing missile is a type of missile that can alter its direction mid-flight to hit a (generally) moving target.Continue reading
