Each bone is rotated to face the target from the tip (by default), which over a chain of bones allow it to rotate properly to reach the target. Because the bones only rotate on a single axis, CCDIK [i]can[/i] look more robotic than other IK solvers. + [b]Note:[/b] The CCDIK modifier has [code]ccdik_joints[/code], which are the data objects that hold the data for each joint in the CCDIK chain. This is different from a bone! CCDIK joints hold the data needed for each bone in the bone chain used by CCDIK. + CCDIK also fully supports angle constraints, allowing for more control over how a solution is met. + </description> + <tutorials> + </tutorials> + <methods> + <method name="get_ccdik_joint_bone2d_node" qualifiers="const"> + <return type="NodePath"> + </return> + <argument index="0" name="joint_idx" type="int"> + </argument> + <description> + Returns the [Bone2D] node assigned to the CCDIK joint at [code]joint_idx[/code]. + </description> + </method> + <method name="get_ccdik_joint_bone_index" qualifiers="const"> + <return type="int"> + </return> + <argument index="0" name="joint_idx" type="int"> + </argument> + <description> + Returns the index of the [Bone2D] node assigned to the CCDIK joint at [code]joint_idx[/code]. + </description> + </method> + <method name="get_ccdik_joint_constraint_angle_invert" qualifiers="const"> + <return type="bool"> + </return> + <argument index="0" name="joint_idx" type="int"> + </argument> + <description> + Returns whether the CCDIK joint at [code]joint_idx[/code] uses an inverted joint constraint.
