How can I create my own logic brick?

Is there a way to create your own logic brick via Python?

Via python, no. Via C++, yes.

Do you know any tutorials for this?

You would need to compile your own modified Blender version in order to do this, are you sure you want to go this way ?
I don’t think there is any tuto, but if you really want to try it here are the Blender sources for UPBGE:

I think it would be easier to make a script, what is your logic brick idea about ?
Chances are that Python could make it happen, without adding a new LB.

Your own custom logic brick is the Python controller.

It serves the frame of a controller and you write python code how to behave.
