Duality is a 2D game engine with an extensible editor (If you follow my blog you’ll see it mention it a few times), I added F# Scripting support a good while ago but I haven’t been posting too much about it, I probably should change that.
Scripting is not the only way to use F# on this engine, you can also create components with F# and it’s pretty simple.
When you run Duality on a folder that has no Data, it creates a solution for plugins by default in Source/Code with two projects: CorePlugin and EditorPlugin. Open the solution and add a F# project. Once it’s created open the project properties and change the assembly name so that it ends with “core”
- Add a reference to Duality.dll and OpenTk.dll (you will find this on the game folder, alternatively have nuget packages too in MyGet )
- Add a new file to the project, it must inherit from Core and read like this
open Duality
type BreakoutFSharpCorePlugin() =
inherit CorePlugin()Lastly if you want to F5 to launch the editor you can add the following to the end of Editor.csproj.user file (replace DualityEditor.exe locations )
</PropertyGroup>
<PropertyGroup Condition="'$(Configuration)|$(Platform)' == 'Debug|AnyCPU'">
<StartAction>Program</StartAction>
<StartProgram>Pathto\where\editor\is\DualityEditor.exe</StartProgram>
<StartWorkingDirectory>Pathto\where\editor\is</StartWorkingDirectory>
</PropertyGroup>
<PropertyGroup Condition="'$(Configuration)|$(Platform)' == 'Release|AnyCPU'">

</PropertyGroup>####Example This is an example of a component
open Duality
open System
[<Serializable>]
type ScoreComponentF() =
inherit Component()
let mutable score =0
member this.Score = score
member this.IncreaseScore amount =
score <- score + amount
