stuminator's ASM hacks

[stuminator]

Here is a compilation of the hacks I've developed.

spoiler: Set individual proc rates for weapons and abilities

<Patch name="Set individual proc rates for weapons and abilities">
  <Description>
    For weapons, set the unknown value to the right of the range from 00-7F to make that the proc rate.  If set from 80-FF, the default proc rate will be used.
    For abilites, check the box between Hit Allies and Follow Target, and the X value will become the proc rate.  Uses default proc rate if unchecked.
    Also includes a support ability to nullify procs, defaulted to Gained XP up, and an ability to double proc rate, defaulted to Train.

  </Patch>

To change the support abilities used to something else, change the bolded digits for the proc nullifying ability, and change the underlined digits for the proc doubling ability.

I also placed the code for this ability into the Golem success code, and instead reassigned Golem to use (MA+X)% success rate.  Since Golem is basically 100% anyway unless your faith is under 48 or so, I hope nobody finds this to be an inconvenience if you decide to use this.

There are a few abilities that you won't be able to set a rate for since they already use the X value like Truth/Untruth/Triple Flame/Demi.

spoiler: Formula 0F = Absorb HP or MP_Y% Hit_F(MA+X)% accepts procs

<Patch name="Formula 0F = Absorb HP or MP_Y% Hit_F(MA+X)% accepts procs">
    <Description>
      Uses the space for both formulas 0F and 10.  Formula 0F now accepts procs.  HP absorb is the default.  To absorb MP, check any box in the element field.

I slightly changed the Formula 0F code from the one I had in the ASM request thread to not conflict with my Individual proc rate hack.

spoiler: Formula 3F = Hit (SP+X)%, can require target to have certain status

<Patch name="Formula 3F = Hit (SP+X)%, can require target to have certain status">
  <Description>
    Overwrites the space of the existing 3F and 40 formula routines.  Also adds physical evasion if evadable is checked.
    Allows you to require an already present status on the target as follows:
    Fill in the Y value in FFTPatcher with 88, 89, 90, 91, or 92 depending on which group the status is in, and check the element field in FFTPatcher corresponding to the status's position in the group.
    If you want the ability to work on any target without requiring an existing status, leave Y=0.  Don't use values for Y other than the ones listed here!
    Remember that the existing Seal Evil ability will need to be updated to the new format to work (Formula 3F, Y=88, element=Wind), and don't assign formula 40 to anything.

spoiler: Monster type check routine

<Patch name="Monster type check routine">
    <Description>
      This creates a monster type check routine that uses the element fields and Y value to allow any formula calling it to only work on whatever monster types you want.
      Monster types are divided into an element group and Y group as follows:
      Element Group:
        Fire=Eyeball
        Lightning=Ghoul
        Ice=Skeleton
        Wind=Squid
        Earth=Panther
        Water=Bomb
        Holy=Goblin
        Dark=Chocobo
      For this group, simply check the element box if you want the ability to be able to target this monster type.
      Y Group:
        128=Hydra
        64=Dragon
        32=Behemoth
        16=Morbol
        8=Minotaur
        4=Woodman
        2=Pig
        1=Bird
      For this group, add up all the values you want the ability to target, and put the sum into the ability Y value.  These values are in decimal.

spoiler: Dragon formulas use monster type check routine

<Patch name="Dragon formulas use monster type check routine">
    <Description>
      This replaces the Dragon check in abilities 5A,5B,5C,5D with a monster type check allowing you specify the types of monsters these abilities work on.
      Note on formulas 5C and 3B:  In order to work with the monster check routine, this makes the status effect field the SP/PA/MA+ value instead of the Y field.
      Both Scream and Dragon Power Up use the same routine, so remember this adjustment if you plan on using either formula.

[Ansehelm]

Nice, these look awesome!
Question about the 3F formula hacks - does this work with multiple statuses within a group?  I.e. an ability that targets both cursed and blood suck units?  I assume there's no way to combine statuses from different groups.

[stuminator]

I didn't try testing it with checking multiple statuses within the same group, but this SHOULD work if more than one status is specified by the elemental box and the target has at least one of them.

When it compares the current status of the target to the status specified by the elemental field, it ANDs the values and considers it a success if it is nonzero.  So it should allow for multiple statuses, as long as they are in the same group. 

And no, I don't think there's a way to combine from different groups.  Maybe one of the vets here would know more about this, but I don't see any way to do it.

[stuminator]

I made a new movement ability to take the place of Move on Lava: Sidestep.  It enables a unit to move through panels that are occupied by enemies.  Obviously not as useful as teleport or the like but should be helpful as a lower tier movement ability, especially for melee classes.  I didn't disable Move on Lava's vanilla function, but it's only useful on one optional map anyway.

Another new movement ability, taking the place of Any Weather.  This disables Any Weather's vanilla function, and allows its user to move and still keep the bonus CT you normally get when not moving.

This is pretty cool, I'm still pretty new to ASM hacking so I would like to ask a question:
If I combined the code in the correct way, would it be possible to combine both new effects into one skill? I think the effects goes pretty well together.

This one is pretty easy to tie to any other RSM ability.  The Bolded 94 represents the group to search for, and the bolded 02 is the specific ability it's tied to.  See the Battle Stats page if you want to change the ability it is tied to:  https://ffhacktics.com/wiki/Battle_Stats

So if you wanted to tie it to Move on Lava, change those to 95 and 20.

Changing the "Sidestep" ability would need a few more lines of code added (unless you want to alter how Float works).  I chose Move on Lava for this because the game already does a check for it in the movement routine where it determines what panels are walkable.  And because Move on Lava is pretty worthless in the vanilla game.

[RetroTypes]

I made a new movement ability to take the place of Move on Lava: Sidestep.  It enables a unit to move through panels that are occupied by enemies.  Obviously not as useful as teleport or the like but should be helpful as a lower tier movement ability, especially for melee classes.  I didn't disable Move on Lava's vanilla function, but it's only useful on one optional map anyway.

Has this Sidestep hack been tested? An initial look-over seems to tell me that the new andi you added will never succeed because you're doing it after another andi that's overwriting the value of r2. I do love the idea for this hack, though, and do plan on writing one myself that will use any RSM because of your inspiration! (I'll post it here when I'm done with it too if you'd like)

It seemed to work just fine on all the tests I did with it.  And it isn't storing the Move on Lava check in r2, but rather r9.  A search in the movement routine revealed that r9 isn't called anywhere so it seemed ok to store it there as it wouldn't be overwritten.

[RetroTypes]

Oh, no I meant the andi two lines prior to where you put yours, but I was mistakenly thinking that it was changing r2 to 1, not to 0x20 if Lavawalking was equipped. I may just leave it the way you did it then! haha thanks for your contributions, btw!

Edit: actually upon further inspection, I bet it can still be written to use any RSM, using one additional line of code in a nop a couple lines up. Lemme try it real quick

This one is pretty easy to tie to any other RSM ability.  The Bolded 94 represents the group to search for, and the bolded 02 is the specific ability it's tied to.  See the Battle Stats page if you want to change the ability it is tied to:  https://ffhacktics.com/wiki/Battle_Stats

So if you wanted to tie it to Move on Lava, change those to 95 and 20.

Changing the "Sidestep" ability would need a few more lines of code added (unless you want to alter how Float works).  I chose Move on Lava for this because the game already does a check for it in the movement routine where it determines what panels are walkable.  And because Move on Lava is pretty worthless in the vanilla game.

So from what I'm understanding is that to create a ability like Side Step I gotta use another ability that checks for movement routine right?
Thanks for the link! I wanted to replace one of the water related abilities instead.

Oh, no I meant the andi two lines prior to where you put yours, but I was mistakenly thinking that it was changing r2 to 1, not to 0x20 if Lavawalking was equipped. I may just leave it the way you did it then! haha thanks for your contributions, btw!

Edit: actually upon further inspection, I bet it can still be written to use any RSM, using one additional line of code in a nop a couple lines up. Lemme try it real quick

So I tried this and it didn't work, do I need to edit some of these values?

EDIT: When I'm moving my unit I can see tiles that would be normally unreachable be highlighted but if I try to move there it tells me I need to select a valid target, so its doing something.

So it looks like the game uses different offsets in the movement routine than it usually does.  0x10 appears to correspond to movement group 0x93, 0x11 is group 0x94, and 0x12 is group 0x95.  So change the first bolded 12 to the group you want, and the second bolded 20 for the ability's position within the group.  I tried 0x11 and 0x10 to tie it to Cannot Enter Water and it worked fine.

Use this version then to change what ability it is tied to.  This will stack with whatever the ability's vanilla function is though, unless you know how to disable it.

Ah, of course, I forgot those weird offset group numbers haha thanks for the correction! (edited my other post to reflect this)
