NOTE: Some features work only on 1.99 Early Access version and above. This is due to some missing gm functions on the older versions. I strongly suggest switching to EA. Here is all the versions available:


Download Windows Demo: (Scanned with AVG 17.5.3021 - Definition v. 170712-10) or

Download OSX Demo: (Scanned wıth AVG 17.2 - Definition v. 170712-10) from Github (Move it to Applications folder if you get 'Game not found' error.


cbDataGUI is an open-source, easy to implement GUI for manipulating object instance variables written in GML.

Best fit for debugging, data visualization, demos and prototyping.

cbDataGUI is based on the idea and the look of Google’s Dat.GUI library.

Allows you to add these controllers with one line of code each:

  • Textbox, (for strings)
  • Slider, (for numbers)
  • Checkbox, (for booleans)
  • Button, (for executing scripts)
  • Color picker, (for colors)
  • Folder. (to organize the elements listed above)

The package contains a gmDoc documentation. For online version visit this [page]:

Looks great

Are you gonna update it to GMS: 2?


Jay R 07 July 2017

Can't compile it.

Looks promising but there are many compile errors. Did you used GM1.4 or GM2?

This review was left for a previous version of this asset.

Asset is updated and it should compile just fine.

I've updated the library on Github. Here is the latest version:
I'll also update the marketplace asset but I'll have to create a new one for Early Access version.

Hello Jay,
I'm using 1.99 Early Access version but I'll make it compatible with 1.4 as soon as possible. Thanks for taking your time to try it.
