Group Follow
Allows for multiple nodes to be followed and affect the PCam
's positional behaviour. It works by setting a Rect2
(2D) or AABB
(3D) bounding box around the targets where the PCam
will track the centre of it.
An Auto Zoom (2D) and Auto Distance (3D) parameter can be applied to dynamically make the PCam
readjust itself to keep multiple targets within view if they start to spread out.
This mode can be useful for single stage experiences that relies on having multiple targets in view at all times.

Properties
Group Targets
Type: Array[Node2D]
Default: null
Defines the nodes that the PCam
should be following.
Note: During runtime, properties should be modified and read via their setters & getters respectively.
Setter
void
append_follow_group_node(Node2D
target_node)
void
append_follow_group_node_array(Array[Node2D]
target_nodes)
void
erase_follow_group_node(Node2D
target_node)
Example
# Appends one node to the Follow Group
pcam.append_follow_group_node(player_node)
# Appends an array of nodes to the Follow Group
pcam.append_follow_group_node_array(node_array)
# Removes a node from the Follow Group
pcam.erase_follow_group_node(another_node)
Damping
Type: bool
Default: false
Applies a damping effect on the Camera
's movement. Leading to heavier / slower camera movement as the targeted node moves around.
This is useful to avoid sharp and rapid camera movement.
Note: During runtime, properties should be modified and read via their setters & getters respectively.
Damping Value
Type: float
Default: 10
Defines the damping amount.
Lower value = slower / heavier camera movement.
Higher value = faster / sharper camera movement.
Note: During runtime, properties should be modified and read via their setters & getters respectively.
Setter
void
set_follow_damping_value(float
damping_value)
Example
pcam.set_follow_damping_value(5)
Auto Zoom (2D)
Type: bool
Default: false
Enables the PCam2D
to dynamically zoom in and out based on the targets' distances between each other.
Once enabled, the PCam
will stay as zoomed in as possible, limited by the Maximum Zoom
and start zooming out as the targets move further apart, limited by the Minimum Zoom
.
Note: Enabling this property hides and disables the Zoom
property as this effectively overrides that value.
This property is for PCam2D
only.
The PCam3D
alternative to this is can be found in the Auto Distance section.
Note: During runtime, properties should be modified and read via their setters & getters respectively.
Min Auto Zoom (2D)
Type: float
Default: 1
Sets the minimum zoom amount, in other words how far away the Camera2D
can be from scene.
This only works when Auto Zoom
is enabled.
This property is for PCam2D
only.
The PCam3D
alternative to this is can be found in the Min Auto Distance section.
Note: During runtime, properties should be modified and read via their setters & getters respectively.
Max Auto Zoom (2D)
Type: float
Default: 5
Sets the maximum zoom amount, in other words how close the Camera2D
can move towards the scene.
This only works when Auto Zoom
is enabled.
This property is for PCam2D
only.
The PCam3D
alternative to this is can be found in the Max Auto Distance section.
Note: During runtime, properties should be modified and read via their setters & getters respectively.
Auto Zoom Margin (2D)
Type: Vector4
Default: Vector4(0,0,0,0)
Determines how close to the edges the targets are allowed to be.
This is useful to avoid targets being cut off at the edges of the screen.
The Vector4
parameter order goes: Left - Top - Right - Bottom.
This property is for PCam2D
only.
The PCam3D
alternative to this is can be found in the Auto Distance Divisor section.
Note: During runtime, properties should be modified and read via their setters & getters respectively.
Setter
void
set_zoom_auto_margin (Vector4
zoom_margin)
Example
pcam.set_zoom_auto_margin(Vector4(10, 30, 10, 40))
Distance (3D)
Type: float
Default: 1
Sets a distance offset from the centre of the target. The distance is applied to the PCam
's local z axis.
This property is for PCam3D
only.
The PCam2D
alternative to this is can be found in the Zoom section.
Note: During runtime, properties should be modified and read via their setters & getters respectively.
Auto Distance (3D)
Type: bool
Default: false
Enables the PCam
to automatically distance itself based on the targets' distances between each other.
It looks at the longest axis between the different targets and interpolates the distance length between the Minimum Distance
and Maximum Distance
properties below.
Note: Enabling this property hides and disables the Distance
property as this effectively overrides that value.
This property is for PCam3D
only.
The PCam2D
alternative to this is can be found in the Auto Zoom section.
Note: During runtime, properties should be modified and read via their setters & getters respectively.
Setter
void
set_auto_follow_distance(bool
should_auto_distance)
Example
pcam.set_auto_follow_distance(true)
Min Auto Distance (3D)
Type: float
Default: 1
Sets the minimum distance between the Camera
and centre of AABB
.
Note: This distance will only ever be reached when all the targets are in the exact same Vector3
coordinate, which will very unlikely happen, so adjust the value here accordingly.
This property is for PCam3D
only.
The PCam2D
alternative to this is can be found in the Max Auto Zoom section.
Note: During runtime, properties should be modified and read via their setters & getters respectively.
Setter
void
set_min_auto_follow_distance(float
min_distance)
Example
pcam.set_min_auto_follow_distance(4.2)
Max Auto Distance (3D)
Type: float
Default: 5
Sets the maximum distance between the Camera
and centre of AABB
.
This property is for PCam3D
only.
The PCam2D
alternative to this is can be found in the Min Auto Zoom section.
Note: During runtime, properties should be modified and read via their setters & getters respectively.
Setter
void
set_max_auto_follow_distance(float
max_distance)
Example
pcam.set_max_auto_follow_distance(4.2)
Auto Distance Divisor (3D)
Type: float
Default: 10
Determines how fast the Auto Distance
moves between the maximum and minimum distance. The higher the value, the sooner the maximum distance is reached.
This value should be based on the sizes of the Minimum Distance
and Maximum Distance
.
E.g. if the value between the Minimum Distance
and Maximum Distance
is small, consider keeping the number low and vice versa.
Note: During runtime, properties should be modified and read via their setters & getters respectively.
Setter
void
set_auto_follow_distance_divisor(float
distance_divisor)
Example
pcam.set_auto_follow_distance_divisor(4.2)
Getter
float
get_auto_follow_distance_divisor()
Example
pcam.get_auto_follow_distance_divisor()
