Integrating ImGui | Coding a 2D Game Engine in Java #17

Join the Discord: https://discord.gg/4tHeAkxNg7

In this tutorial I discuss how to integrate ImGui into our current project. I also briefly go over an alternative repository to use if you would like to use Maven, and discuss some workarounds if you would like to use a precompiled JAR. I first talk about the difference in the retained mode paradigm and the immediate mode paradigm. Then I show how we can import the Java port to ImGui using Gradle. After we have the library imported, I talk about how we can use the example on the Github repository to set up our own ImGui layer. We finally get the demo window showing, and leave further considerations for future tutorials.

If you decide to use Kotlin Graphics, remember that you will have to include the Kotlin runtime in your build, and I also had to include this uno-sdk in my build to get it working. The uno-sdk issue is discussed here: https://github.com/kotlin-graphics/imgui/issues/112
