CopyTransformModifier3D

Inherits BoneConstraint3D

A SkeletonModifier3D that apply transform to the bone which copied from reference.

Description

Apply the copied transform of the bone set by BoneConstraint3D.set_reference_bone() to the bone set by BoneConstraint3D.set_apply_bone() with processing it with some masks and options. There are 4 ways to apply the transform, depending on the combination of set_relative() and set_additive(). Relative + Additive: - Extract reference pose relative to the rest and add it to the apply bone's pose. Relative + Not Additive: - Extract reference pose relative to the rest and add it to the apply bone's rest. Not Relative + Additive: - Extract reference pose absolutely and add it to the apply bone's pose. Not Relative + Not Additive: - Extract reference pose absolutely and the apply bone's pose is replaced with it. Note: Relative option is available only in the case BoneConstraint3D.get_reference_type() is BoneConstraint3D.REFERENCE_TYPE_BONE. See also BoneConstraint3D.ReferenceType.

Properties

`int setting_count = 0`

The number of settings in the modifier.

Methods

`int get_axis_flags(int index) const`

Returns the axis flags of the setting at index.

`int get_copy_flags(int index) const`

Returns the copy flags of the setting at index.

`int get_invert_flags(int index) const`

Returns the invert flags of the setting at index.

`bool is_additive(int index) const`

Returns true if the additive option is enabled in the setting at index.

`bool is_axis_x_enabled(int index) const`

Returns true if the enable flags has the flag for the X-axis in the setting at index. See also set_axis_flags().

`bool is_axis_x_inverted(int index) const`

Returns true if the invert flags has the flag for the X-axis in the setting at index. See also set_invert_flags().

`bool is_axis_y_enabled(int index) const`

Returns true if the enable flags has the flag for the Y-axis in the setting at index. See also set_axis_flags().

`bool is_axis_y_inverted(int index) const`

Returns true if the invert flags has the flag for the Y-axis in the setting at index. See also set_invert_flags().

`bool is_axis_z_enabled(int index) const`

Returns true if the enable flags has the flag for the Z-axis in the setting at index. See also set_axis_flags().

`bool is_axis_z_inverted(int index) const`

Returns true if the invert flags has the flag for the Z-axis in the setting at index. See also set_invert_flags().

`bool is_position_copying(int index) const`

Returns true if the copy flags has the flag for the position in the setting at index. See also set_copy_flags().

`bool is_relative(int index) const`

Returns true if the relative option is enabled in the setting at index.

`bool is_rotation_copying(int index) const`

Returns true if the copy flags has the flag for the rotation in the setting at index. See also set_copy_flags().

`bool is_scale_copying(int index) const`

Returns true if the copy flags has the flag for the scale in the setting at index. See also set_copy_flags().

`void set_additive(int index, bool enabled)`

Sets additive option in the setting at index to enabled. This mainly affects the process of applying transform to the BoneConstraint3D.set_apply_bone(). If sets enabled to true, the processed transform is added to the pose of the current apply bone. If sets enabled to false, the pose of the current apply bone is replaced with the processed transform. However, if set set_relative() to true, the transform is relative to rest.

`void set_axis_flags(int index, int axis_flags)`

Sets the flags to copy axes. If the flag is valid, the axis is copied.

`void set_axis_x_enabled(int index, bool enabled)`

If sets enabled to true, the X-axis will be copied.

`void set_axis_x_inverted(int index, bool enabled)`

If sets enabled to true, the X-axis will be inverted.

`void set_axis_y_enabled(int index, bool enabled)`

If sets enabled to true, the Y-axis will be copied.

`void set_axis_y_inverted(int index, bool enabled)`

If sets enabled to true, the Y-axis will be inverted.

`void set_axis_z_enabled(int index, bool enabled)`

If sets enabled to true, the Z-axis will be copied.

`void set_axis_z_inverted(int index, bool enabled)`

If sets enabled to true, the Z-axis will be inverted.

`void set_copy_flags(int index, int copy_flags)`

Sets the flags to process the transform operations. If the flag is valid, the transform operation is processed. Note: If the rotation is valid for only one axis, it respects the roll of the valid axis. If the rotation is valid for two axes, it discards the roll of the invalid axis.

`void set_copy_position(int index, bool enabled)`

If sets enabled to true, the position will be copied.

`void set_copy_rotation(int index, bool enabled)`

If sets enabled to true, the rotation will be copied.

`void set_copy_scale(int index, bool enabled)`

If sets enabled to true, the scale will be copied.

`void set_invert_flags(int index, int axis_flags)`

Sets the flags to inverte axes. If the flag is valid, the axis is copied. Note: An inverted scale means an inverse number, not a negative scale. For example, inverting 2.0 means 0.5. Note: An inverted rotation flips the elements of the quaternion. For example, a two-axis inversion will flip the roll of each axis, and a three-axis inversion will flip the final orientation. However, be aware that flipping only one axis may cause unintended rotation by the unflipped axes, due to the characteristics of the quaternion.

`void set_relative(int index, bool enabled)`

Sets relative option in the setting at index to enabled. If sets enabled to true, the extracted and applying transform is relative to the rest. If sets enabled to false, the extracted transform is absolute.
