Raycast to terrain

Question

How can I get the point clicked on the terrain, to move my player to that position? Im using the terrain plugin, but I would like to know how to do it in case Im using a plane or other mesh.

Comments

I've tried doing stuff like this (with mixed results). IIRC, when the player clicks on the screen, a ray can be cast from where they clicked (more information on that can be found here). Where that ray intersects the geometry (in one game, I used the code get_world().direct_space_state.intersect_ray() to figure out what geometry intersected the ray).

Hope that helps.

oh that's actually useful.

Forgot to mention that intersect_ray() also takes parameters.

I have tried this previously , just put this script on a camera and read the position of the clickpos variable and it should work ... and make sure whatever mesh you are using it should have a static body child or parent , and a collision mesh , because you need colliders to make it work

extends Camera
var ray=RayCast.new()
var clickpos= Vector3(0,0,0)
func _ready():
    add_child(ray)
    ray.enabled=true

func _input(event):
    var clicked = (GetMouseClick(event))

func GetMouseClick(event):
    var distance_from_camera = far 
    if event is InputEventMouseButton:
            var from = project_ray_origin(event.position);
            var to = from + project_ray_normal(event.position) * distance_from_camera;
            ray.cast_to = to-global_transform.origin
            if (event is InputEventMouseButton):
                if (event.pressed == false and event.button_index == 1): #check if Left Click is released 
                    if ray.is_colliding():
                        var raypoint = ray.get_collision_point()
                        return (raypoint)

A little question (Im still a newbie with Godot), how do I read clickpos from another script? Or can I do the movement from inside that script attached to the camera?

in your other object script write this :

get_node("camera_path").click_pos

remember to replace camera_path with the suitable path for the camera in your project

BTW, I dont see clickpos being assigned in any place. Shouldnt be this way?

func _input(event):
clickpos = (GetMouseClick(event))
