position

NOTE: This version of the documentation tracks unstable development happening on A-Frame’s master branch. If you wish to try it out, grab the unstable build. Otherwise, head to the documentation for the current 0.7.0 version

The position component places entities at certain spots in 3D space. Position takes a coordinate value as three space-delimited numbers.

All entities inherently have the position component.

Example

<a-entity position="0 1 -1"></a-entity>

Value

A-Frame uses a right-handed coordinate system where the negative Z axis extends into the screen. The table below assumes looking down the negative Z axis from the origin.

Axis Description Default Value
x Negative X axis extends left. Positive X Axis extends right. 0
y Negative Y axis extends down. Positive Y Axis extends up. 0
z Negative Z axis extends in. Positive Z Axis extends out. 0

Relative Positioning

World-space positions of child entities inherit from parent entities. Consider this scene:

<a-entity id="parent" position="1 2 3">
<a-entity id="child1"></a-entity>
<a-entity id="child2" position="2 3 4"></a-entity>
</a-entity>

The world-space position of #child1 would be 1 2 3 as inherited by the entity. In the local parent’s space, #child1‘s position would be 0 0 0.

The world-space position of #child2 would be 3 5 7, by combining the position with the parent entity. In the parent’s local space, #child2‘s position would be 2 3 4.
