CollisionObject2D

int collision_layer = 1

The physics layers this CollisionObject2D is in. Collision objects can exist in one or more of 32 different layers. See also collision_mask. Note: Object A can detect a contact with object B only if object B is in any of the layers that object A scans. See Collision layers and masks in the documentation for more information.

int collision_mask = 1

The physics layers this CollisionObject2D scans. Collision objects can scan one or more of 32 different layers. See also collision_layer. Note: Object A can detect a contact with object B only if object B is in any of the layers that object A scans. See Collision layers and masks in the documentation for more information.

float collision_priority = 1.0

The priority used to solve colliding when occurring penetration. The higher the priority is, the lower the penetration into the object will be. This can for example be used to prevent the player from breaking through the boundaries of a level.

int disable_mode = 0

Defines the behavior in physics when Node.process_mode is set to Node.PROCESS_MODE_DISABLED.

bool input_pickable = true

If true, this object is pickable. A pickable object can detect the mouse pointer entering/leaving, and if the mouse is inside it, report input events. Requires at least one collision_layer bit to be set.

void _input_event(Viewport viewport, InputEvent event, int shape_idx) virtual

Accepts unhandled InputEvents. shape_idx is the child index of the clicked Shape2D. Connect to input_event to easily pick up these events. Note: _input_event() requires input_pickable to be true and at least one collision_layer bit to be set.

void _mouse_enter() virtual

Called when the mouse pointer enters any of this object's shapes. Requires input_pickable to be true and at least one collision_layer bit to be set. Note that moving between different shapes within a single CollisionObject2D won't cause this function to be called.

void _mouse_exit() virtual

Called when the mouse pointer exits all this object's shapes. Requires input_pickable to be true and at least one collision_layer bit to be set. Note that moving between different shapes within a single CollisionObject2D won't cause this function to be called.

void _mouse_shape_enter(int shape_idx) virtual

Called when the mouse pointer enters any of this object's shapes or moves from one shape to another. shape_idx is the child index of the newly entered Shape2D. Requires input_pickable to be true and at least one collision_layer bit to be called.

void _mouse_shape_exit(int shape_idx) virtual

Called when the mouse pointer exits any of this object's shapes. shape_idx is the child index of the exited Shape2D. Requires input_pickable to be true and at least one collision_layer bit to be called.

Removes the given shape owner.

void set_collision_layer_value(int layer_number, bool value)

Based on value, enables or disables the specified layer in the collision_layer, given a layer_number between 1 and 32.

void set_collision_mask_value(int layer_number, bool value)

Based on value, enables or disables the specified layer in the collision_mask, given a layer_number between 1 and 32.

int shape_find_owner(int shape_index) const

Returns the owner_id of the given shape.

void shape_owner_add_shape(int owner_id, Shape2D shape)

Adds a Shape2D to the shape owner.

void shape_owner_clear_shapes(int owner_id)

Removes all shapes from the shape owner.

Object shape_owner_get_owner(int owner_id) const

Returns the parent object of the given shape owner.

Shape2D shape_owner_get_shape(int owner_id, int shape_id) const

Returns the Shape2D with the given ID from the given shape owner.

void shape_owner_remove_shape(int owner_id, int shape_id)

Removes a shape from the given shape owner.

void shape_owner_set_disabled(int owner_id, bool disabled)

If true, disables the given shape owner.

void shape_owner_set_one_way_collision(int owner_id, bool enable)

If enable is true, collisions for the shape owner originating from this CollisionObject2D will not be reported to collided with CollisionObject2Ds.

void shape_owner_set_one_way_collision_margin(int owner_id, float margin)

Sets the one_way_collision_margin of the shape owner identified by given owner_id to margin pixels.

void shape_owner_set_transform(int owner_id, Transform2D transform)

Sets the Transform2D of the given shape owner.

input_event(Node viewport, InputEvent event, int shape_idx)

Emitted when an input event occurs. Requires input_pickable to be true and at least one collision_layer bit to be set. See _input_event() for details.

mouse_entered()

Emitted when the mouse pointer enters any of this object's shapes. Requires input_pickable to be true and at least one collision_layer bit to be set. Note that moving between different shapes within a single CollisionObject2D won't cause this signal to be emitted. Note: Due to the lack of continuous collision detection, this signal may not be emitted in the expected order if the mouse moves fast enough and the CollisionObject2D's area is small. This signal may also not be emitted if another CollisionObject2D is overlapping the CollisionObject2D in question.

mouse_exited()

Emitted when the mouse pointer exits all this object's shapes. Requires input_pickable to be true and at least one collision_layer bit to be set. Note that moving between different shapes within a single CollisionObject2D won't cause this signal to be emitted. Note: Due to the lack of continuous collision detection, this signal may not be emitted in the expected order if the mouse moves fast enough and the CollisionObject2D's area is small. This signal may also not be emitted if another CollisionObject2D is overlapping the CollisionObject2D in question.

mouse_shape_entered(int shape_idx)

Emitted when the mouse pointer enters any of this object's shapes or moves from one shape to another. shape_idx is the child index of the newly entered Shape2D. Requires input_pickable to be true and at least one collision_layer bit to be set.

mouse_shape_exited(int shape_idx)

Emitted when the mouse pointer exits any of this object's shapes. shape_idx is the child index of the exited Shape2D. Requires input_pickable to be true and at least one collision_layer bit to be set.

DISABLE_MODE_REMOVE = 0

DISABLE_MODE_MAKE_STATIC = 1

Enum: DisableMode

When Node.process_mode is set to Node.PROCESS_MODE_DISABLED, make the body static. Doesn't affect Area2D. PhysicsBody2D can't be affected by forces or other bodies while static. Automatically set PhysicsBody2D back to its original mode when the Node is processed again.

DISABLE_MODE_KEEP_ACTIVE = 2

Enum: DisableMode

When Node.process_mode is set to Node.PROCESS_MODE_DISABLED, do not affect the physics simulation.
