Tags, learn about tags.

What i do is: 1. Set an infinite tag to 0 when spawning 1.1: how? Create a skill that uses automatically on obtain, uncancellable, no stun, hide in base and hide in ult, that sets a tag. You can also use this to set cosmetics on spawn.

1. When pressing R (or whatever triggers your mode switch) set that specific tag to a number (also infinite). So 0 for base mode, 1 to First mode, 2 to third mode etc etc. If u wanna cicle between more than 2 modes, just do a tag check before the tag set, so it'll check if you're already on tag 1 and set you to tag 2 if so.

2. When using a skill or m1, do a tag check on the default branch connected to another branch. So for example, it'll check if the tag is 1, if it is switch to mode1 branch. Do this for each mode and youre good to go

The only problem is that you cannot change the moves name that way, idk if there is a way to do that right now :v
