The rotation component defines the orientation of an entity. It takes the roll (x), pitch (y), and yaw (z) as three space-delimited numbers indicating degrees of rotation.

All entities inherently have the rotation component.


<a-entity rotation="45 90 180"></a-entity>


A-Frame uses a right-handed coordinate system. When aligning our right hand’s thumb with a positive axis, our hand will curl in the positive direction of rotation.

Axis Description Default Value
x Roll, rotation about the X-axis. 0
y Pitch, rotation about the Y-axis. 0
z Yaw, rotation about the Z-axis. 0

Relative Rotation

Child entities inherit from world-space rotations from parent entities. Consider this scene:

<a-entity id="parent" rotation="0 45 0">
<a-entity id="child-1"></a-entity>
<a-entity id="child-2" rotation="15 45 30"></a-entity>

The world-space rotation of #child1 would be 0 45 0 as inherited by the entity. In the local parent’s space, #child1‘s rotation would be 0 0 0.

The world-space rotation of #child2 would be 15 90 30, by combining the rotation with the parent entity. In the parent’s local space, #child2‘s rotation would be 15 45 30.
