The Haxe programming language is capable of generating code in several other languages, including more recently the Lua programming language. The Defold game engine is a powerful free 2.5D game engine from King, that we have covered extensively in tutorial series. It was only a matter of time until the two came together, and that is exactly what has happened. The hxdefold open source project enables you to program Defold using the Haxe programming language.
- Fully typed Defold API with proper compile-time errors and IDE services.
- Type-safe game object messages and properties with zero overhead.
- Strengths of Haxe without compromises: powerful type system, meta-programming, static optimizations and cross-target code sharing.
The getting started instructions are pretty straight forward, from the Github page:
- Install this library (from this repo):
haxelib git hxdefold https://github.com/hxdefold/hxdefold
haxelib run hxdefold init inside your Defold project. It will create a sample
Hello.hx script component class and a
build.hxml for building it.
- Read the comments in these files to quickly get some idea.
- Build with
haxe build.hxml to get the lua output.
Hello.script to your game object in the editor and observe the greeting in the debug console.
- Proceed with writing well-structured, expressive and type safe code for your Defold game.
The editor won’t become Haxe aware however, so you will still have to build your code externally.
