[ASM & Hex✓] (I need help)How to change waterfall and dive to activate with flags?[EM]

[rubenturen]

im using emerald
Hi I guess that you know that when you go close to a waterfall with the move waterfall you can assend it
(The same with dive just on dark spots)

I want to do so that it instead checks for a flag or item
Instead of a move

Because I want to do so that hm dive and waterfall are upgrades of surf

So that I just need to do so that when you get surf you can't ascend waterfalls or dive in deep waters
But when a flag is active you can do one of them and another flag for the other

I don't mind if you think that it's stupid
Bc i just want to know how to do this

You might want to have a look at the HM scripts and try replacing them with your own scripts that remove the attack check. Once you've created your own custom script, you'd need to repoint to it via hex editor (replace the offset with the offset of your new one).

Waterfall's script offset: 290A49
Dive's script offset: 290B0F
Resurfacing from Dive: 290B5A

Oh could you also give me the offsets for the other hm scripts

Rock Smash: 2907A6

Fly & Flash are a bit different since they're called from the party menu rather than the overworld.
