This is the about of CGE.
I use Lazarus version 3.4 with Windows 10.
Maybe, I must download a new version of CGE.
The InitializeDebug / InitializeRelease calls have been added around the July 7th, see this news: Regenerate Your Project for better Debug / Release settings in both Lazarus and Delphi (and to be prepared for secret features coming next week) – Castle Game Engine . So, yes, you need to upgrade Castle Game Engine if you miss them.
I have upgraded Castle Game Engine and I can run the BlueIcaro project. It works good, but not with the solution where I am looking for. BlueIcaro uses the handwork to move the paddle and ball, but I will use the physics so that the rigidbody calculates the move and the bounce automatically. What I can do in Unity, to use a physics material, will not work in CGE. But I will looking for solutions to make a BrickBreaker game without friction. Maybe it is possible to make a function that imitates the physics material. First I must make more tests for finding these techniques.
