<brief_description>
The [AimModifier3D] rotates a bone to look at a reference bone.
</brief_description>
<description>
This is a simple version of [LookAtModifier3D] that only allows bone to the reference without advanced options such as angle limitation or time-based interpolation.
The feature is simplified, but instead it is implemented with smooth tracking without euler, see [method set_use_euler].

<methods>
<method name="get_forward_axis" qualifiers="const">
<return type="int" enum="SkeletonModifier3D.BoneAxis" />
<param index="0" name="index" type="int" />
<description>
Returns the forward axis of the bone.
</description>
</method>
<method name="get_primary_rotation_axis" qualifiers="const">
<return type="int" enum="Vector3.Axis" />
<param index="0" name="index" type="int" />
<description>
Returns the axis of the first rotation. It is enabled only if [method is_using_euler] is [code]true[/code].
</description>
</method>
<method name="is_relative" qualifiers="const">
<return type="bool" />
<param index="0" name="index" type="int" />
<description>
Returns [code]true[/code] if the relative option is enabled in the setting at [param index].
</description>
</method>
<method name="is_using_euler" qualifiers="const">
<return type="bool" />
<param index="0" name="index" type="int" />
<description>
Returns [code]true[/code] if it provides rotation with using euler.
</description>
</method>
<method name="is_using_secondary_rotation" qualifiers="const">
<return type="bool" />
<param index="0" name="index" type="int" />
<description>
Returns [code]true[/code] if it provides rotation by two axes. It is enabled only if [method is_using_euler] is [code]true[/code].
</description>
</method>
<method name="set_forward_axis">
<return type="void" />
<param index="0" name="index" type="int" />
<param index="1" name="axis" type="int" enum="SkeletonModifier3D.BoneAxis" />
<description>
Sets the forward axis of the bone.
</description>
</method>
<method name="set_primary_rotation_axis">
<return type="void" />
<param index="0" name="index" type="int" />
<param index="1" name="axis" type="int" enum="Vector3.Axis" />
<description>
Sets the axis of the first rotation. It is enabled only if [method is_using_euler] is [code]true[/code].
</description>
</method>
<method name="set_relative">
<return type="void" />
<param index="0" name="index" type="int" />
<param index="1" name="enabled" type="bool" />
<description>
Sets relative option in the setting at [param index] to [param enabled].
If sets [param enabled] to [code]true[/code], the rotation is applied relative to the pose.
If sets [param enabled] to [code]false[/code], the rotation is applied relative to the rest. It means to replace the current pose with the [AimModifier3D]'s result.

</method>
<method name="set_use_euler">
<return type="void" />
<param index="0" name="index" type="int" />
<param index="1" name="enabled" type="bool" />
<description>
If sets [param enabled] to [code]true[/code], it provides rotation with using euler.
If sets [param enabled] to [code]false[/code], it provides rotation with using rotation by arc generated from the forward axis vector and the vector toward the reference.

<method name="set_use_secondary_rotation">
<return type="void" />
<param index="0" name="index" type="int" />
<param index="1" name="enabled" type="bool" />
<description>
If sets [param enabled] to [code]true[/code], it provides rotation by two axes. It is enabled only if [method is_using_euler] is [code]true[/code].
