I made a small plugin to turn a Path3d into a MeshInstance to draw the level geometry. (Grey box)
But I wanted a fast tool, and Path3d points appear at some distance from the camera, which is inconvenient.
Editor’s camera need me only to cast surface. In Godo 3.5.1 I can use forward_spatial_gui_input in plugin, but In 4.0 it replaced by _forward_3d_gui_input(viewport_camera: Camera3D, event: InputEvent) and just don’t work.
Edited. Found the answer as soon as I asked the question.
func _forward_3d_gui_input(p_camera: Camera3D, p_event: InputEvent):
if p_event is InputEventMouseButton:
if p_event.button_index == MOUSE_BUTTON_LEFT:
var viewport = p_camera.get_viewport()
var viewport_container = viewport.get_parent()
var screen_pos = viewport.get_mouse_position()
var origin = p_camera.project_ray_origin(screen_pos)
var dir = p_camera.project_ray_normal(screen_pos)
var ray_distance := p_camera.far
var cast = PhysicsRayQueryParameters3D.new()
cast.from = origin
cast.to = origin + dir * ray_distance
var root = get_tree().get_edited_scene_root()
var space = root.get_world_3d().direct_space_state
# Transfer to the selected object.
now_obj.raycast_result = space.intersect_ray(cast)
# Or save local to use.
# _raycast_result = space.intersect_ray(cast)
func _handles(object: Object):
if object is Path3D:
now_obj = object
return true
return false
