Creating your own ImGui based project

You can easily generate a Dear ImGui project using init from the github version of Orx.

This article assumes that you have downloaded the latest version of Orx from github and have built Orx.

There are two ways to create a Dear ImGui project. Firstly, using Interactive Mode:

init 

Then follow all the prompts and choose yes when asked if you want to include Dear ImGui:

[Extension] imgui: Dear ImGui support (https://github.com/ocornut/imgui)? (no)

The second way is to specify everything on the commandline:

init myGameFolder/MyGame +imgui

Load your new Dear ImGui project using your favourite IDE. You'll find your build in the build folder.

Compile and run. You should get a nice screen with demo gui controls.

And just for some extra flair, add a little up/down movement to the logo in your main config file:

[Object]
Graphic         = @
Texture         = logo.png
Pivot           = center
AngularVelocity = 18
FXList          = FadeIn # ColorCycle # MoveAround
 
[MoveAround]
SlotList        = @
Type            = position
StartTime       = 0.0
EndTime         = 4
Curve           = sine
StartValue      = (0,0)
EndValue        = (0, -300)
Loop            = true

You can also create an orx/Scroll-based Dear ImGui project. See: Creating your own orx/Scroll project using 'init'
