Dynamically change atlas of an object

Questions

Hello! New Defold user here. I’m wondering if it’s possible to change/swap an atlas of a sprite at runtime?

List item

I tried using:

go.set("#sprite", "image", hash("/game/atlas/skin_002.atlas"))

The path seems to be correct, but the game returns “go.set failed with error code -10”

Then I tried:
go.set("#sprite", "image", "/game/atlas/skin_002.atlas")
which obviously returns “the property ‘image’ of ‘#sprite’ must be a hash”

I’ve seen posts on the forum where users define the atlas as a resource like this
go.property("skin_xmas", resource.atlas())
and then use it :
go.set("/go#sprite", "image", self.skin_xmas)

Second approach seems to be working for me, but I’m not sure if I want to use it for something more complex as it feels a bit hardcoded. Is that approach totally fine, or am I missing something here?

Dynamically change atlas with variable

It is. If the resources is not referenced it is not included in the bundle

Exactly this. Defold will not include resources without a reference in the scene graph. Using go.property("foo", resource.atlas("/my.atlas")) will make sure the my.atlas is referenced and included in the build.

Here’s a similar example (although using a tilesource instead of an atlas, but the principle is the same):
