The code to rebind keys took me too long, but the end I got what I wanted (I think the pressing time is too long, maybe 1s is enough).
The collisions are strange because the code is unfinished, in theory the trees would have to prevent drone movement, but I was not able to make the Navigation2D + NavigationPolygon work as I wanted by modifying them at runtime with the silhouette of the tree trunks :(
