Interesting indeed, but what would be the use case for this action? I'm still quite new to game dev but this action looks useful, i just don't know for what exactly.

... what would be the use case for this action?

in a scene you'd set up a loop to iterate through the X/Z "locations" (doesn't need to be objects in a grid, could get 1 value for a specific location). At each pass through the loop (at the different X/Z) the action returns a normalized value between 0 and 1.

The minecraft-looking terrain scene is (probably) cubes set at a height (Y) multiplied by the Perlin value.

Reasons to use Perlin noise over random numbers is the smooth undulation, and predicatability. Perlin looks organically random but gives consistent values – super-helpful for procedural generation.
