PhysicsRayQueryParameters2D

继承： RefCounted < Object

Provides parameters for PhysicsDirectSpaceState2D.intersect_ray.

描述

By changing various properties of this object, such as the ray position, you can configure the parameters for PhysicsDirectSpaceState2D.intersect_ray.

属性说明

bool collide_with_areas = false

  • void set_collide_with_areas ( value: bool )
  • bool is_collide_with_areas_enabled ( )

If true, the query will take Area2D s into account.

bool collide_with_bodies = true

  • void set_collide_with_bodies ( value: bool )
  • bool is_collide_with_bodies_enabled ( )

If true, the query will take PhysicsBody2D s into account.

int collision_mask = 4294967295

  • void set_collision_mask ( value: int )
  • int get_collision_mask ( )

The physics layers the query will detect (as a bitmask). By default, all collision layers are detected. See Collision layers and masks in the documentation for more information.

Array RID exclude = []

The list of object RID s that will be excluded from collisions. Use CollisionObject2D.get_rid to get the RID associated with a CollisionObject2D-derived node.

Note: The returned array is copied and any changes to it will not update the original property value. To update the value you need to modify the returned array, and then assign it to the property again.

Vector2 from = Vector2(0, 0)

The starting point of the ray being queried for, in global coordinates.

bool hit_from_inside = false

  • void set_hit_from_inside ( value: bool )
  • bool is_hit_from_inside_enabled ( )

If true, the query will detect a hit when starting inside shapes. In this case the collision normal will be Vector2(0, 0). Does not affect concave polygon shapes.

Vector2 to = Vector2(0, 0)

The ending point of the ray being queried for, in global coordinates.

方法说明

PhysicsRayQueryParameters2D create ( from: Vector2, to: Vector2, collision_mask: int = 4294967295, exclude: Array RID = [] ) static1

Returns a new, pre-configured PhysicsRayQueryParameters2D object. Use it to quickly create query parameters using the most common options.


    var query = PhysicsRayQueryParameters2D.create(global_position, global_position + Vector2(0, 100))
    var collision = get_world_2d().direct_space_state.intersect_ray(query)
