3d wallrunning for an fps gane

Same as my last post, I am making a movement shooter. How do I do a fps wallrun? Someone in the Gdevelop 3d discord named Puko had a really good 3d wallrun and he commented the following screenshot. However, his instructions were a little unclear and there weren’t any screenshots of the events. using 3d raycast also disabled by shooting as well. Does anyone know how to make a fps wallrun? I also want to know how to rotate the camera so the wallrun looks better. Anything would help. Thanks
