<class name="ShapeCast" inherits="Spatial" version="3.6" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../class.xsd">
<brief_description>
Node for physics collision sweep and immediate overlap queries. Similar to the [RayCast] node.
</brief_description>
<description>
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]Vector3(0, 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 [Area] when used as a continuous detection area, often requiring waiting a couple of frames before collision information is available to [Area] nodes, and when using the signals creates unnecessary complexity.
The node can detect multiple collision objects, but it's usually used to detect the first collision.
[b]Note:[/b] Shape casting is more computationally expensive compared to ray casting.

<methods>
<method name="add_exception">
<return type="void" />
<argument index="0" name="node" type="Object" />

</description>
</method>
<method name="add_exception_rid">
<return type="void" />
<argument index="0" name="rid" type="RID" />

</method>
<method name="clear_exceptions">

</description>
</method>
<method name="force_shapecast_update">
<return type="void" />
<description>
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[/code] is not required for this to work.

<return type="float" />
<description>
The fraction from the [ShapeCast]'s origin to its [member target_position] (between 0 and 1) of how far the shape can move without triggering a collision.
</description>
</method>
<method name="get_closest_collision_unsafe_fraction" qualifiers="const">
<return type="float" />
<description>
The fraction from the [ShapeCast]'s origin to its [member target_position] (between 0 and 1) of how far the shape must move to trigger a collision.

<return type="Object" />
<argument index="0" name="index" type="int" />
<description>
Returns the collided [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]).

<description>
Returns the shape ID of the colliding shape of one of the multiple collisions at [code]index[/code], or [code]0[/code] if no object is intersecting the shape (i.e. [method is_colliding] returns [code]false[/code]).
</description>
</method>
<method name="get_collision_count" qualifiers="const">
<return type="int" />
<description>
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.
</description>
</method>
<method name="get_collision_mask_value" qualifiers="const">
<return type="bool" />
<argument index="0" name="layer_number" type="int" />
<description>
Returns whether or not the specified layer of the [member collision_mask] is enabled, given a [code]layer_number[/code] between 1 and 32.
</description>
</method>
<method name="get_collision_normal" qualifiers="const">
<return type="Vector3" />
<argument index="0" name="index" type="int" />
<description>
Returns the normal of one of the multiple collisions at [code]index[/code] of the intersecting object.
</description>
</method>
<method name="get_collision_point" qualifiers="const">
<return type="Vector3" />
<argument index="0" name="index" type="int" />
<description>
Returns the collision point of one of the multiple collisions at [code]index[/code] where the shape intersects the colliding object.
[b]Note:[/b] this point is in the [b]global[/b] coordinate system.
</description>
</method>
<method name="is_colliding" qualifiers="const">
<return type="bool" />
<description>
Returns whether any object is intersecting with the shape's vector (considering the vector length).
</description>
</method>
<method name="remove_exception">
<return type="void" />
<argument index="0" name="node" type="Object" />
