Returns a blank `Datatype.RaycastParams` object. Unlike other data type
constructors, this constructor does not have any parameters, so you should
set its properties appropriately.

RaycastParams.new

Returns a blank `Datatype.RaycastParams`.

The `Datatype.RaycastParams` data type stores parameters for
`Class.WorldRoot:Raycast()` operations. The
`Datatype.RaycastParams.ExcludeInstances|ExcludeInstances` and
`Datatype.RaycastParams.IncludeInstances|IncludeInstances` properties store a
set of objects and their descendants that will be excluded and included from
the query. The `Datatype.RaycastParams.IgnoreWater` property can be used to
ignore `Class.Terrain` water, and the `Datatype.RaycastParams.CollisionGroup`
property can specify a collision group for the raycasting operation.

This object is different from the similarly named `Datatype.RaycastResult`
which provides the results of a raycast.

Unlike most data types in Luau, you can change all of the members of
`Datatype.RaycastParams` without creating a new object, allowing you to reuse
the same object repeatedly.


Adds the instances provided to
`Datatype.RaycastParams.FilterDescendantsInstances|FilterDescendantsInstances`.
Note that this property has been superseded by
`Datatype.RaycastParams.ExcludeInstances|ExcludeInstances` and
`Datatype.RaycastParams.IncludeInstances|IncludeInstances` which should be
used for new work.


RaycastParams:AddToFilter

instances

An instance or an array containing instances to add.


Adds the instances provided to
`Datatype.RaycastParams.FilterDescendantsInstances|FilterDescendantsInstances`.


RaycastParams

An optional array of instances whose descendants will be excluded from the
query. This property can be used simultaneously with
`Datatype.RaycastParams.IncludeInstances|IncludeInstances` to allow for
mixed filtering, for example including a large folder but excluding
specific child instances. If an instance matches both an exclude and
include filter, exclusions take priority over inclusions.


RaycastParams.ExcludeInstances

An optional array of instances whose descendants will be excluded from the
query.


An optional array of instances whose descendants will be included in the
query. This property can be used simultaneously with
`Datatype.RaycastParams.ExcludeInstances|ExcludeInstances` to allow for
mixed filtering. If an instance matches both an exclude and include
filter, exclusions take priority over inclusions.

Setting `IncludeInstances` to `nil` versus an empty array (`{}`) has
opposite effects. `IncludeInstances = nil` is the most permissive filter
(includes everything), whereas `IncludeInstances = {}` is the most
restrictive filter (includes nothing).


RaycastParams.IncludeInstances

An optional array of instances whose descendants will be included in the
query.


Determines whether the water material is considered when raycasting
against `Class.Terrain`.


RaycastParams.IgnoreWater

Specifies a collision group for the raycasting operation. Parts in
collision groups that are set to **not** collide with this group are
ignored. If this property is omitted, the raycast assumes the **Default**
collision group.


RaycastParams.CollisionGroup

The collision group used for the operation.


This property, if `true`, makes the raycast operation use an intersected
part's `Class.BasePart.CanCollide|CanCollide` value in favor of its
`Class.BasePart.CanQuery|CanQuery` value when determining whether that
part is included in the `Datatype.RaycastResult`.


RaycastParams.RespectCanCollide

Determines whether the raycast operation considers a part's
`Class.BasePart.CanCollide|CanCollide` property value over its
`Class.BasePart.CanQuery|CanQuery` value.


When enabled, the query will ignore all part collision properties and
perform a brute-force check on every part. This will negatively impact
performance and should not be used in live experiences.


RaycastParams.BruteForceAllSlow

When enabled, the query will ignore all part collision properties and
perform a brute-force check on every part.


An array of objects whose descendants are used to filter raycasting
candidates. Note that this property has been superseded by
`Datatype.RaycastParams.ExcludeInstances|ExcludeInstances` and
`Datatype.RaycastParams.IncludeInstances|IncludeInstances` which should be
used for new work.


RaycastParams.FilterDescendantsInstances

An array of objects whose descendants are used to filter raycasting
candidates.


Determines whether the
`Datatype.RaycastParams.FilterDescendantsInstances|FilterDescendantsInstances`
array is used as an exclude or include list. Note that this property has
been superseded by
`Datatype.RaycastParams.ExcludeInstances|ExcludeInstances` and
`Datatype.RaycastParams.IncludeInstances|IncludeInstances` which should be
used for new work.


RaycastParams.FilterType

Determines whether the
`Datatype.RaycastParams.FilterDescendantsInstances|FilterDescendantsInstances`
array is used as an exclude or include list.


A container for parameters used in raycasting operations.

This method is asynchronous and returns an `Operation`, which represents the current state of the operation. It contains an endpoint path that you can poll to obtain the real response and applicable metadata. See the [documentation]({longRunningOperationsLink}) on long-running operations for more information.
            
The following sections describe the response and metadata objects that are provided when an operation completes.

Beta endpoints are ready for public use. Breaking changes are possible but rare.

These Open Cloud documentation pages will be removed on March 31, 2026. You will be automatically redirected to the new Open Cloud documentation at that time. {linkStart}Learn more{linkEnd}

Experimental endpoints are ready for public use, but may experience breaking changes occasionally as the API contract is finalized.

This endpoint can be called in-experience through {httpServiceLinkStart}HttpService{httpServiceLinkEnd} with an API key.

This field may be set when creating a resource, but may not be modified by subsequent requests.

Scopes control what permissions your credentials have. Your credentials can only access the endpoints supported by the scopes you selected.

Stable endpoints are production-ready and will almost never experience breaking changes during their lifetime.

This target enables you to limit your key's access to selected {requiredParts}

This target enables you to limit your key's access to selected {requiredParts} and {optionalParts}

Target types are used to restrict the resources that your credentials have permissions on. Only the selected resources can be acted on even if your account has permissions on additional resources. Some scopes do not have target parts. In these cases, all of your relevant resources can be acted on.

The universe Top Level Part does not need to be selected for user-owned API Keys. In this case, your API Key will have access to all of your user-owned experiences and group-owned experiences that you have the right group permissions on.
