SkeletonModificationStack2D

Experimental: This class may be changed or removed in future versions.

Inherits: Resource < RefCounted < Object

A resource that holds a stack of SkeletonModification2Ds.

Description

This resource is used by the Skeleton and holds a stack of SkeletonModification2Ds.

This controls the order of the modifications and how they are applied. Modification order is especially important for full-body IK setups, as you need to execute the modifications in the correct order to get the desired results. For example, you want to execute a modification on the spine before the arms on a humanoid skeleton.

This resource also controls how strongly all of the modifications are applied to the Skeleton2D.

Properties

Methods

Property Descriptions

bool enabled = false 🔗

• void set_enabled(value: bool)

• bool get_enabled()

If true, the modification’s in the stack will be called. This is handled automatically through the Skeleton2D node.

int modification_count = 0 🔗

• void set_modification_count(value: int)

• int get_modification_count()

The number of modifications in the stack.

float strength = 1.0 🔗

• void set_strength(value: float)

• float get_strength()

The interpolation strength of the modifications in stack. A value of 0 will make it where the modifications are not applied, a strength of 0.5 will be half applied, and a strength of 1 will allow the modifications to be fully applied and override the Skeleton2D Bone2D poses.

Method Descriptions

void add_modification(modification: SkeletonModification2D) 🔗

Adds the passed-in SkeletonModification2D to the stack.

void delete_modification(mod_idx: int) 🔗

Deletes the SkeletonModification2D at the index position mod_idx, if it exists.

void enable_all_modifications(enabled: bool) 🔗

Enables all SkeletonModification2Ds in the stack.

void execute(delta: float, execution_mode: int) 🔗

Executes all of the SkeletonModification2Ds in the stack that use the same execution mode as the passed-in execution_mode, starting from index 0 to modification_count.

Note: The order of the modifications can matter depending on the modifications. For example, modifications on a spine should operate before modifications on the arms in order to get proper results.

bool get_is_setup() const 🔗

Returns a boolean that indicates whether the modification stack is setup and can execute.

SkeletonModification2D get_modification(mod_idx: int) const 🔗

Returns the SkeletonModification2D at the passed-in index, mod_idx.

Skeleton2D get_skeleton() const 🔗

Returns the Skeleton2D node that the SkeletonModificationStack2D is bound to.

void set_modification(mod_idx: int, modification: SkeletonModification2D) 🔗

Sets the modification at mod_idx to the passed-in modification, modification.

void setup() 🔗

Sets up the modification stack so it can execute. This function should be called by Skeleton2D and shouldn’t be manually called unless you know what you are doing.
