Javascript library by Google, for building visual programming editors.

Gdevelop (Free & Open Source)
Event based system, can be extended using Javascript (HTML5 target), or C++ (Native target).
Similar Tools: Construct 2 (Free & Commercial)

Note: Basically, there are two most popular types of visual programming as scripting system in game editors - node & wire based and block based. My personal favorite is block based, more specifically, GDevelop-style. The reason is the presentation of logic in block based visual programming is "linear". Node & wire based visual programming is very flexible, but as the presentation can be non-linear ("messy"), it usually has low readability (just think the "wires" as the notorious keyword "goto"). Block based is more similar to line by line text-based structured programming, and it is easier to structure and organize, and hence usually have better readability. Scratch and blocky are too similar to text-based programming and almost have no advantages over text-based programming, so I think most programmers would not bother using them. GDevelop gives a better example of block type - the event driven, condition & action approach is very intuitive and convenient.

Goo Create (Free & Commercial)
Goo Create open source online WebGL game editor has a state machine visual programming system.


  1. Node-based scripting system of Unreal engine can be extended with C++ programming really? this is great to know, so no programming needed, thank you for sharing

  2. I have heard the this system can be more clear. The provides a qualitative help with writing. I will be waiting for the next posts.
