GLBasic vs uScript + Unity3D

Language is easy to use, with a fast compiler.

Forum support is great. No advertising in program or forums. Company has been going for over 10 years.

Unlike most multi-platform development systems, 3D is available across most of them.

Code can be written once and will work on supported platforms with very little modification.

PC version is free.

Full Multi-platform version requires one-off very reasonable price, and all further updates are free, however you can run a watermarked demo on your chosen platform with the free demo version.

C/C++ code can be included inline or as a DLL/.o/dylib file.

Only problem is position is based on position of previous widget.

Create apps for non commercial 2D programs running on Windows, Linux and Mac OSX. The extension to create programs for other platforms, 3D or network applications requires a license key. Otherwise the "Premium" programs are limited to 10 min runtime for test purposes. There is no trial limit for the development environment.

Easy-to-use networking system with either TCP or UDP.

Programmers reference guide, user guide and various others are free.

Viewports, sprites, rotating/animating and zooming sprites, collision detection and pathfinding.

uScript's nodes are a visual representation of actual code blocks, and it takes advantage of C#'s reflection capabilities to automatically create nodes for any scripts it finds in your project, regardless of the source. This makes it inherently compatible with pretty much everything.

Custom nodes can also be created by hand, for cases where the automatically created ones contain more elements than they actually need.

Modeled after UDK's Kismet (the predecessor to UE4's Blueprint), uScript's scripts resemble flowcharts where each box represents a function or value, with connections between them representing program flow. This provides a better at-a-glance indication of game logic than a simple list of events, and makes complex behaviors easier to accomplish.

Nodes are translated directly to C# files in your project. This is great for learning to code, and also for advanced users who can use uScript for fast prototyping and then further optimize the scripts if necessary.
