I bought the softwar and used the particle creator, it's really cool and made some cool effects with it. Awesome Stuff! Once done I used the export to GMS 2 option and got the GML code.

I am unable to figure out how to use these particles inside GMS 2. The included gmz file is a complete project but I want to use GeonFX in my previously made projects, and in documentation it says to add gmez extension but that file is not available?

It's likely that I am missing something very basic.

Can you please help me with this?


Thank you for buying Geon FX! You can export particles to GML and put them into your code: 

Just copy and paste the code into your project. The extension is provided via the GameMaker: Marketplace. I'll add it here too for your comfort.

Thanks !!

I am not able to link my itch.io purchase to Game Maker Marketplace. And it's asking me to purchase again.

Can you please add the extension on itch.io download page? That would be really helpful!


Added Geon_FX_-_Particle_Editor.gmez. Please check, download and import following the instruction here: http://www.steampanic.com/geonfx/faq#import_gmez

Great it worked now!! Thank you for the quick support :D

Any chance to have it for 001 Game Creator, GDevelop and Godot? Those are the engines I'm currently using.

Hi, I will have to take a look how much different their formats are and how to convert to them. What about built-in editors for those engines? Do they suck? I'm working on export to GIF and PNG strip right now.

Hi and thanks for your reply.

Honestly, I'm not a programmer, I'm a multimedia designer with my main focus on game art. So I don't use those engines often. I have them because I'm learning my way around (when I have some free time) and because the programmers I'm working with at the moments use them, so I need them for testing my assets, etc. I can't tell you much about how good their build-in editors are compared to GMS for example. Godot and Gdevelop are FOSS so you can download them and see. For 001 it's proprietary but they have a demo version (I think) so you can try that too. Anyway those three engines lacks stuffs like GeonFX, so I think it's almost a "open" market for you. You should take your chances ^_^. Ren'Py also being very popular, maybe you might wanna check that too.

I have bought GMS 1.4, two or three years ago, but I doubt I'll use it since I'm quite bad at coding, that mean I might not (maybe I'll change my mind later) aquire GeonFX for now. 

Any chance you could make it compatible for Construct 2 or Clickteam Fusion?

Yes, we'll be working on it. Please follow us on Twitter for more details on upcoming updates: https://twitter.com/steampanic

Awesome, done. Let me know if you do any Alpha/Beta test for Construct 2 (main engine I'm working in ATM), I'd be happy to test.
