So I must learn the stuff from the beginning. My natural language is not English, I hope you can forgive me a mistake or two .
If you want test the code you make a new project and a map. I made some test objects to see if climbing fails or not and under which steps I can crouch
and on which step I can jump.
I make this blog for me to save the source code. Two times in my life I lost nearly all my source I programmed by HardDrive crashes.
So it is a nice thing to have that online. And for beginnes to have a start code.
In your project folder, by me in "documents/Leadwerks/Projects/.... <-- here are my Projects"
you have a subfolder also named projects:
"documents/Leadwerks/Projects/ProjectName/projects/"
by me in the folder windows is the VisualStudio 17 project: "ProjectName.sln" << Start this with Doubleclick, but first install VisualStudio.
I delete all the stuff inside main.cpp, App.cpp and app.h
and put the following code in main.cpp
change your mapname > "YouMapName.map" from your project and compile. I can not say whats the menu names in english because I have the german GUI.
For VisualStudio tutorials look in the Web or YouTube, I am sure there are dozens of them.

The next step I will made is to put the code into a class.
Use the C Key for toggle crouching and use the CTRL for faster runnig, the I have walk with Key W, jogging with Shift+W and running with CTRL and W.
