Reverse Scaling Question

[SonicTheBombhog]

I'm curious. Would it be possible to make a reverse version of the parallax object to replicate how Hydrocity Zone makes use of another background water sprite with reverse scaling when you're beneath the water?

Presentation stage literally does that. It is an argument of the bg_convert_scaled function

I do know how the function itself works. The thing is, Presentation stage only has one sprite for the water with vertical scaling while Hydrocity has two separate water sprites. I actually came up my own solution! I just stacked the two on top of each other and made one of the two layers visible, depending on the camera's position. Thank you Triangly for this answer though, I'm going to use it for a separate original level.

Hmm. I'm glad you figured out a solution on your own! I just don't recall Hydro City having different water sprites. Could you elaborate, please?

These two images, I am referring to. Hydrocity has these two different water sprites that can change palettes when underwater, but the second image is the only one that is supposed to be VISIBLE with underwater palettes when underwater. This is what I was able to make which closely matches the original:

The first water sprite is visible and colored normally, but below the water, the second water sprite appears, colored with the underwater palettes.

This is what the first water sprite looks like underwater palettes:

That's the exact same sprite tho! You could just make it use different colours from everything else, and then apply the above-water and underwater palettes to it

Ya know I actually didn't notice that... the second water IS like the first one but flipped... I thought they were different.... -_- that would be a much more elegant solution
