I am having a game object.
I am increasing the size of the game object using game logic by setting the scale of the game object, however I am not able to change the size of the box of the collision object. Is there an API reference document or a better way to achieve this?
The support for physics scaling was added today in Defold 1.2.170. Read more in the release notes: https://forum.defold.com/t/defold-1-2-170-has-been-released/65631
