Changes to both "set_cellv" and "update_bitmask_region" in Godot 4.3

Godot Version

4.3

Question

Hey guys, I’m a beginner to Godot and was following this pretty cool tutorial on procedural generation from Heartbeast https://www.youtube.com/watch?v=2nk6bJBTtlA&t=319s

I’ve gotten through most of it, but eventually learned that there were some changes to the syntax of GD script that prevents old code from running. In my case it’s the “set_cellv” and “update_bitmask_region” methods. Being a beginner to GD script, I don’t know enough about these methods to translate them into GD script 4.3, but I really want to finish the tutorial. Does anyone know the equivalent methods to these two? For further context, I’m currently at minute 20:23 of the tutorial

Thanks in advance!
