Hi there, I'm trying to make a cheat to make the player invincible, ie non-responsive to enemy attack hitboxes for MH4U (EUR) 1.1
I'm kind of new to this, and I'm using cheat engine to look for values that shift when the player is hit, since I figured down the code that flags "you've been hit" like that, and I keep finding quite a few, but when I follow those values to codes that write to that value and replace them with inactive code, nothing seems to actually do anything, and after a several hours of this and no clue what I'm doing wrong or what to do instead I'm starting to lose it. I'm wondering if maybe it's too hard to find the flag because it's only active for a frame or so, so I'm finding other things?
I need this to help record footage for videos (so Citra is necessary, though I can't imagine why that would matter) without getting knocked around by the monsters, but for the life of me I can't figure out what to do about it. I have a code that does this for MHXX (Japanese GU) but I haven't been able to/don't know how to recreate this MH4U. Making a script for infinite health was easy, but all the stuff that stops me from moving into the right positions because of hits or roars or tremors or whatever is not.
I was able to get something working at some point with one code that seemed like it worked because I disabled some flag *when* I disabled it rather than *why* since just disabling it in general doesn't actually keep the player from getting hit, so that's no good.
In particular, if I disable the code at (address give:
in the middle of invincibility after getting hit, then I retain the invincibility, but not if I just do it. This code in particular seems to control when certain player animations end? Since if you're running with it disabled you won't stop rolling if you let go of the directional input, and if activated when knocked through the air you'll never land. More annoyingly, in the same manner the player's animations will continue without ending, it seems to affect the monsters in the same way, which is *absolutely* not what I want.
There was with the array that
43 8B 04 1C - mov eax,[r12+r11]
That seemed to do the exact same thing where just causes the player to continue their current animation endlessly, but does not render invincibility when activated at the right time.
Also found what seems to flag wind pressure reaction at
43 8B 04 1C - mov eax,[r12+r11]
Which I wasn't looking for specifically but was glad to find, I guess. Even though I also lost it again...
Incidentally I also found some continuous check that seems to make the monster stop attacking the player but still can't find a way to stop the player from reacting to hits, lmao.
I also would would ideally get something to move the camera into different positions relative to the player, since I haven't been able to figure anything other than altering the camera angle (someone else had made a code for this already, lol).
EDIT: I understand these are kind of useless, but well it crashed when I was still digging around.
