Really strange tutorial video

Theres this video at this link:

Randomness In Gdevelop | How to Generate Random number in Gdevelop

And the video has RNG, but am I wrong in thinking it doesn’t use any extension? Because that’s what it looks like. But, that being said, I was unaware that GDevelop already had randomness, and if it did, then why did anybody take the time to put it in an extension?

Theres stuff designed for this exact thing, it’s literally built in to GDevelop, you don’t need an extension for randomness.

They use the actual Randomness functions in GDevelop. I use a non existant Variable here, but you can have it set it to a Variable you have between whatever two numbers you want.
