what does $RayCast.get_collision_normal() function mean guys?
And what does this command mean?
var basis = get_global_transform().basis
when i move the mouse with print(basis.x) or print(basis.z), it returns a vector variable, what does this vector value mean

The normal vector is at a right angle to the collision. Described here in the article on Vector Math:
Normal vectors are unit vectors aligned perpendicularly to a surface, defining its direction.
A Basis is a matrix (3 Vector3 objects) which describe how a 3D object is scaled and rotated local to the 3D object. The global_transform part calculates it with respect to the scene as a whole.
can you give me a concrete example of get_collision_nomal() function

Do you mean a code example, or an example of it in action, e.g. a picture or a diagram?

i read some documents and i understand the return value of get_collision_normal() function is a normal vector with collision point , its true?

More or less. get_collision_point() returns the point in space where the RayCast intersected the object. get_collision_normal() gives a vector that’s at a right angle to the object’s shape at the collision point.
