Node for physics collision sweep and immediate overlap queries. Similar to the [RayCast2D] node. Shape casting allows to detect collision objects by sweeping the [member shape] along the cast direction determined by [member target_position] (useful for things like beam weapons). Immediate collision overlaps can be done with the [member target_position] set to [code]Vector2(0, 0)[/code] and by calling [method force_shapecast_update] within the same [b]physics_frame[/b]. This also helps to overcome some limitations of [Area2D] when used as a continuous detection area, often requiring waiting a couple of frames before collision information is available to [Area2D] nodes, and when using the signals creates unnecessary complexity. The node can detect multiple collision objects, but usually the first detected collision [b]Note:[/b] shape casting is more computationally expensive compared to ray casting. Adds a collision exception so the shape does not report collisions with the specified node. Adds a collision exception so the shape does not report collisions with the specified [RID]. Removes all collision exceptions for this shape. Updates the collision information for the shape. Use this method to update the collision information immediately instead of waiting for the next [code]_physics_process[/code] call, for example if the shape or its parent has changed state. [b]Note:[/b] [code]enabled == true[/code] is not required for this to work. The fraction of the motion (between 0 and 1) of how far the shape can move without triggering a collision. The motion is determined by [member target_position]. The fraction of the motion (between 0 and 1) when the shape triggers a collision. The motion is determined by [member target_position]. Returns the [Object] of one of the multiple collisions at [code]index[/code], or [code]null[/code] if no object is intersecting the shape (i.e. [method is_colliding] returns [code]false[/code]). Returns the shape ID of one of the multiple collisions at [code]index[/code] that the shape intersects, or [code]0[/code] if no object is intersecting the shape (i.e. [method is_colliding] returns [code]false[/code]). The number of collisions detected at the point of impact. Use this to iterate over multiple collisions as provided by [method get_collider], [method get_collider_shape], [method get_collision_point], and [method get_collision_normal] methods. Returns whether or not the specified layer of the [member collision_mask] is enabled, given a [code]layer_number[/code] between 1 and 32. Returns the normal containing one of the multiple collisions at [code]index[/code] of the intersecting object. Returns the collision point containing one of the multiple collisions at [code]index[/code] at which the shape intersects the object. [b]Note:[/b] this point is in the [b]global[/b] coordinate system. Returns whether any object is intersecting with the shape's vector (considering the vector length). Removes a collision exception so the shape does report collisions with the specified node. Removes a collision exception so the shape does report collisions with the specified [RID]. Based on [code]value[/code], enables or disables the specified layer in the [member collision_mask], given a [code]layer_number[/code] between 1 and 32. If [code]true[/code], collision with [Area2D]s will be reported. If [code]true[/code], collision with [PhysicsBody2D]s will be reported. The shape's collision mask. Only objects in at least one collision layer enabled in the mask will be detected. A complete collision information. The data returned is the same as in the [method PhysicsDirectSpaceState2D.get_rest_info] method. If [code]true[/code], collisions will be reported. If [code]true[/code], the parent node will be excluded from collision detection. The collision margin for the shape. A larger margin helps detecting collisions more consistently, at the cost of precision. The number of intersections can be limited with this parameter, to reduce the processing time. Any [Shape2D] derived shape used for collision queries. The shape's destination point, relative to this node's [code]position[/code].
