Setting Up PhysicsPointQueryParameters3D

To use the PhysicsPointQueryParameters3D class in Godot 4, you first need to create an instance of it. This is the starting point to configure your query parameters.

var query_parameters =

Once you have an instance, you can set various properties. For instance, defining the point where you want the query to occur is as simple as:

query_parameters.position = Vector3(0, 1, 0)

Configuring Collision Layers and Masks

Physics layers determine which objects will be considered during the physics query. By setting collision masks, you define which layers will be included in the collisions.

query_parameters.collision_mask = 1 # Only check for collisions with objects in layer 1

To include multiple layers, you can use bitwise operations to combine layer masks:

query_parameters.collision_mask = 1|2 # Check for collisions with objects in layers 1 and 2

You can also exclude certain areas or bodies from the query:


Executing the Query

To query the physics space, you’ll use the PhysicsServer3D.point_query method along with the parameters you’ve defined.

var results = PhysicsServer3D.point_query(query_parameters)

The results variable now contains information about what the physics server found at the specified point. If you’re querying for bodies, the result will be an array of dictionaries, each representing a body that was found.

Interpreting Query Results

Each dictionary in the results array contains valuable information about the collision, such as the colliding object’s instance ID and the collision position. You can iterate over the results to extract and utilize this data:

for result in results:
    var colliding_instance_id = result.collider_id
    var collision_point = result.position
    # Do something with the colliding instance
    var colliding_object = ObjectDB.instance_from_id(colliding_instance_id)
    if colliding_object:
        print("Collided with ",

This information allows you to respond to physics events precisely, such as creating effects at the point of collision or determining the object the player has interacted with.

Effective usage of the PhysicsPointQueryParameters3D class can dramatically improve the interactivity and realism of your game. Stay tuned for part three where we’ll explore more complex examples and use cases, helping you to utilize the full potential of physics queries within Godot 4.

Now that you’re familiar with the basic setup and execution of point queries using the PhysicsPointQueryParameters3D class, let’s explore more advanced usage and intricate examples to harness its full potential.

Let’s say you want to determine if an area is occupied before spawning a new object. Here’s how you could perform a check:

func is_position_occupied(position):
    var query_parameters =
    query_parameters.position = position
    query_parameters.collision_mask = 1
    var results = PhysicsServer3D.point_query(query_parameters)
    return results.size() > 0

if not is_position_occupied(Vector3(10, 0, 10)):
    spawn_object_at(Vector3(10, 0, 10))

This checks if there are any colliders at the given position and spawns an object only if the position is unoccupied.

Sometimes you may want to adjust the shape of the query area. While PhysicsPointQueryParameters3D is point-based, you can combine it with an Area node for shape-based queries. In this case, you first need to retrieve the Area’s collision shape:

var area_shape = $Area.get_shape()

With the shape in hand, you can configure your query parameters to include it:


Now the query uses the Area’s shape for its physics check.

Advanced queries may require refining which objects you receive information about. For instance, you may want to only consider dynamic bodies:

query_parameters.exclude_static_bodies = true

Conversely, you might be interested solely in static bodies, such as the level geometry:

query_parameters.exclude_dynamic_bodies = true

You may also want to execute a query in response to an event. For example, if a character casts a spell, you might need to determine the target:

func cast_spell(from_position, target_position):
    var query_parameters =
    query_parameters.position = target_position
    var results = PhysicsServer3D.point_query(query_parameters)
    for result in results:
        var colliding_instance_id = result.collider_id
        if colliding_instance_id != from_position.get_instance_id():
            var target = ObjectDB.instance_from_id(colliding_instance_id)

This function checks for any bodies at the target position that aren’t the caster, and applies spell effects accordingly.

Lastly, consider optimizing your queries. If you perform physics queries often, consider reusing the PhysicsPointQueryParameters3D instance rather than creating a new one each time:

var query_parameters =

func perform_query(position):
    query_parameters.position = position
    return PhysicsServer3D.point_query(query_parameters)

# Use this method whenever you need to perform a point query

By learning to use PhysicsPointQueryParameters3D effectively in Godot 4, you’re taking a significant step towards creating dynamic and responsive game worlds. Always remember that while physics queries are powerful, they should be used judiciously to maintain performance, especially in extensive 3D environments or on less powerful hardware.

Enhancing gameplay mechanics through physics queries can provide players with a more robust and engaging experience. To facilitate this, we must delve deeper into coding paradigms within Godot 4’s physics system. Here, we’ll examine additional scenarios where PhysicsPointQueryParameters3D can be utilized.

For instance, you might want to simulate a sensing mechanism, such as an enemy detecting a player’s presence:

var query_parameters =
query_parameters.position = enemy_position
query_parameters.collision_mask = player_collision_layer

var results = PhysicsServer3D.point_query(query_parameters)
for result in results:
    if result.collider_id == player.get_instance_id():

In this example, the enemy checks its surroundings for the player’s presence by querying a specific collision layer associated with the player.

Another powerful feature is adjusting the query’s collision mask at runtime to react to different gameplay scenarios. This can enable or disable certain interactions dynamically:

func enable_interaction_with_layer(layer_number, enable):
    if enable:
        query_parameters.collision_mask |= 1 << layer_number
        query_parameters.collision_mask &= ~(1 << layer_number)

This function toggles interaction with a specific layer on or off, based on the ‘enable’ parameter, by setting or clearing the appropriate bit in the collision mask.

Physics queries can also be sequenced to perform complex interactions, as seen in puzzle mechanics or multi-step processes:

var first_query =
first_query.position = first_point
var first_results = PhysicsServer3D.point_query(first_query)

if first_results.size() > 0:
    var second_query =
    second_query.position = second_point
    var second_results = PhysicsServer3D.point_query(second_query)
    if second_results.empty():

Here, two point queries are used to trigger a puzzle mechanic only if specific conditions are met, creating a sequence dependent on player interactions or other game state changes.

It’s also possible to query the physics space for the closest body or area by iterating over multiple points. This can emulate radar or waypoint systems:

var closest_body = null
var closest_distance = INF
var query_points = [Vector3(0, 0, 1), Vector3(1, 0, 0), Vector3(0, 0, -1), Vector3(-1, 0, 0)]

for point in query_points:
    var query =
    query.position = point
    var results = PhysicsServer3D.point_query(query)
    for result in results:
        var distance = position.distance_to(result.position)
        if distance < closest_distance:
            closest_distance = distance
            closest_body = ObjectDB.instance_from_id(result.collider_id)

if closest_body:
    print("Closest object is: ",

This snippet searches for the nearest physics body around a certain position using multiple queries and reports it.

Another consideration for advanced physics queries is performance. For frequent and intensive querying, consider using Godot’s threading capabilities to offload the processing and maintain smooth gameplay:

func threaded_query(query_parameters):
    var thread =
    thread.start(self, "_execute_point_query", query_parameters)

func _execute_point_query(query_parameters):
    var results = PhysicsServer3D.point_query(query_parameters)
    # Process your results here
    # Don't forget to wrap any calls that affect the scene tree in a call_deferred() to avoid threading issues

By offloading the query to a separate thread, you ensure that the main game thread remains responsive, and your game continues running smoothly.

Leveraging the flexibility and control provided by PhysicsPointQueryParameters3D, you can design intricate and polished gameplay elements, from stealth and surveillance systems to environmental interactions and puzzle mechanics. As you continue to explore Godot 4’s physics capabilities, remember to benchmark and profile your game to ensure that the use of physics queries balances both gameplay complexity and performance efficiency.
