Semi confusing warning

JediMindTrix · December 25, 2015

The following block of weidu code returns a warning "Warning: no effects were added" (paraphrased). This is true, as effects were only altered or deleted, but I'm curious as to whether I'm doing something wrong.

//SPL Patching - Dark Taint and Hand of Murder fixes
COPY_EXISTING ~BHAAL2B.spl~ ~override~ //Dark Taint Fixes
LPF ALTER_EFFECT    //Level 1 - 9 slow
INT_VAR
  check_globals = 0
  check_headers = 1
  header = 1
  match_opcode = 40
  savebonus = (0 - 2)
END
LPF ALTER_EFFECT    //Level 10 - 12 slow
INT_VAR
  check_globals = 0
  check_headers = 1
  header = 2
  match_opcode = 40
  savebonus = (0 - 2)
END

LPF ALTER_EFFECT    //Level 13 - 14 slow
INT_VAR
  check_globals = 0
  check_headers = 1
  header = 3
  match_opcode = 40
  savebonus = (0 - 2)
END

LPF ALTER_EFFECT    //Level 15 - 16 slow
INT_VAR
  check_globals = 0
  check_headers = 1
  header = 4
  match_opcode = 40
  savebonus = (0 - 2)
END

LPF ALTER_EFFECT    //Level 17 - 20 slow
INT_VAR
  check_globals = 0
  check_headers = 1
  header = 5
  match_opcode = 40
  savebonus = (0 - 2)
END

LPF ALTER_EFFECT    //Level 21 - 25 slow
INT_VAR
  check_globals = 0
  check_headers = 1
  header = 8
  match_opcode = 40
  savebonus = (0 - 4)
END

LPF ALTER_SPELL_HEADER    //Level 25 Visual Effect Fix
INT_VAR
  match_icon = 1
  header = 8
  projectile = 237
STR_VAR
  resource = SPPR411B
END

LPF DELETE_SPELL_HEADER //Removes extra version of spell that partly breaks progression
INT_VAR
  min_level = 19
END
BUT_ONLY

Cheers!

I had the same problem and you will find the reason why here: http://forums.pocketplane.net/index.php/topic,29445.0.html

All integer variables except check_globals, check_headers, header and savebonus default to -1 and negative values result in no change to the corresponding field.

Briefly, here is the response from wisp:

In 239 you will be able to use the keyword UNDEFINED as a value when declaring functions. The variable will then be undefined in the function's scope, even if it is defined outside the function, unless the user passes a value for the variable when launching the function.

JediMindTrix · December 26, 2015

I am still confused.

Are you saying that none of the saving throws I've defined with (0 - y) are actually committing the negative value?

Or are you saying the values I have not defined at all are returning in the function as a negative number and then preventing the desired change from occurring?

JediMindTrix · December 26, 2015

Trying to use undefined returns a "cannot convert to integer" error.

LPF ALTER_EFFECT    //Level 1 - 9 slow
INT_VAR
  check_globals = 0
  check_headers = 1
  header_type = 1
  header = 1
  multi_match = 1
  verbose = 1
  match_opcode = 40
  match_target = UNDEFINED
  match_power = UNDEFINED
  match_parameter1 = UNDEFINED
  match_parameter2 = UNDEFINED
  match_timing = UNDEFINED
  match_resist_dispel = UNDEFINED
  match_duration = UNDEFINED
  match_probability1 = UNDEFINED
  match_probability2 = UNDEFINED
  match_dicenumber = UNDEFINED
  match_dicesize = UNDEFINED
  match_savingthrow = UNDEFINED
  match_savebonus = UNDEFINED
  match_special = UNDEFINED
  match_resource = UNDEFINED
  savebonus = (0 - 2)
END

EDIT:

Even this returns a warning:

LPF ALTER_EFFECT    //Level 1 - 9 slow
INT_VAR
  check_globals = 0
  check_headers = 1
  header_type = 1
  header = 1

  match_opcode = 40
  match_target = 2
  match_power = 6
  match_parameter1 = 0
  match_parameter2 = 0
  match_timing = 0
  match_resist_dispel = 1
  match_duration = 12
  match_probability1 = 100
  match_probability2 = 0
  match_dicenumber = 0
  match_dicesize = 0
  match_savingthrow = 2
  match_savebonus = 0
  match_special = 0
  match_resource = 0
  opcode = 40
  target = 2
  power = 6
  parameter1 = 0
  parameter2 = 0
  timing = 0
  resist_dispel = 1
  duration = 12
  probability1 = 100
  probability2 = 0
  dicenumber = 0
  dicesize = 0
  savingthrow = 0
  savebonus = (0 - 2)
  special = 0
  STR_VAR
  resource = 0
END

Trying to use undefined returns a "cannot convert to integer" error.

Pmhh...

Try using just this instead:

LPF ALTER_EFFECT    //Level 1 - 9 slow
INT_VAR
  check_globals = 0
  check_headers = 1
  header_type = 1
  header = 1
  multi_match = 1
  verbose = 1
  match_opcode = 40
  savebonus = ~-2~
END

YOU DON'T want to use the UNDEFINED, ever.

JediMindTrix · December 26, 2015

That made no difference.

What does the .debug say exactly ? Open the file in your game folder with Notepad.

What Gwendolyne is saying is that these functions do not work with negative values right now.

WeiDU 239 is not released and the functions have not been modified to work with negative values yet.

JediMindTrix · December 26, 2015

So there is no way to patch Dark Taint to not be broken xD

Thanks!

Mike1072 · December 26, 2015

You would have to do it without using those functions.

Avenger · December 26, 2015

You can submit negative values to weidu with 0xffffffff = -1, 0xfffffffe = -2, etc.

Gwendolyne · December 26, 2015

As I did not want to wait for WeiDU 239 release, I wrote my own function. You can adapt it to your needs :

DEFINE_PATCH_FUNCTION ~GW_MODIFY_ST_BONUS~
    INT_VAR GW_oldbonus      = "-99"      // old bonus to check
            GW_newbonus      = "-99"      // new bonus to write
BEGIN

    PATCH_IF (GW_oe = 0) BEGIN            // Creatures : NO Extended Headers !
        SET abil_off = 0
        SET abil_num = 0
    END ELSE BEGIN
        READ_LONG  GW_oe abil_off
        READ_SHORT GW_oc abil_num
        READ_LONG  GW_fx fx_off
    END
    FOR (i = 0 ; i < abil_num ; ++i) BEGIN                                          // looks through headers
        READ_SHORT (abil_off + 0x1e + GW_al*i) "abil_fx_num"
        READ_SHORT (abil_off + 0x20 + GW_al*i) "abil_fx_idx"
        FOR (j = 0 ; j < abil_fx_num ; ++j ) BEGIN                                  // looks through effects
            READ_LONG (fx_off + 0x24 + (0x30 * (j + abil_fx_idx))) ST               // reads ST
            READ_LONG (fx_off + 0x28 + (0x30 * (j + abil_fx_idx))) savebonus        // reads ST bonus

            PATCH_IF ((GW_oldbonus = savebonus) OR (GW_oldbonus = "-99")) BEGIN
                PATCH_IF ((GW_newbonus != savebonus) AND (GW_newbonus != "-99")) BEGIN
                    WRITE_LONG (fx_off + 0x28 + (0x30 * (j + abil_fx_idx))) GW_newbonus
                END
            END
        END    // of looping through effects
    END        // of looping through heders

END    // of DEFINE_PATCH_FUNCTION

Before, I launch this one :

DEFINE_PATCH_FUNCTION ~GW_DEF_OFFSETS_FILE~
    RET GW_oe        // Extended Header offset
        GW_oc        // Extended Header count
        GW_al        // Extended Header length (ability length)
        GW_fx        // Feature blocks offset
        GW_fi        // Equipping-Casting feature blocks index
        GW_fc        // Equipping Feature Blocks count
        GW_min_size  // Minimum size
BEGIN

    READ_ASCII 0 sig (3)
    PATCH_MATCH ~%sig%~ WITH
        ITM    BEGIN    SET GW_oe = 0x64    // Extended Header offset
                    SET GW_oc = 0x68        // Extended Header count
                    SET GW_al = 0x38        // Extended Header length (ability length)
                    SET GW_fx = 0x6a        // Feature blocks offset
                    SET GW_fi = 0x6e        // Equipping feature blocks index
                    SET GW_fc = 0x70        // Equipping Feature Blocks count
                    SET GW_min_size = 0x71  // Minimum size
        END
        SPL    BEGIN    SET GW_oe = 0x64    // Extended Header offset
                    SET GW_oc = 0x68        // Extended Header count
                    SET GW_al = 0x28        // Extended Header length (ability length)
                    SET GW_fx = 0x6a        // Feature Block Table offset
                    SET GW_fi = 0x6e        // Casting Feature Block offset
                    SET GW_fc = 0x70        // Casting Feature Block count
                    SET GW_min_size = 0x71  // Minimum size
        END
        CRE BEGIN    SET GW_oe = 0           // Extended Header offset
                    SET GW_oc = 0            // Extended Header count
                    SET GW_al = 0            // Extended Header length (ability length)
                    SET GW_fx = 0x2c4        // Effects offset
                    SET GW_fi = 0            // Casting Feature Block offset
                    SET GW_fc = 0x2c8        // Effects count
                    SET GW_min_size = 0x2d3  // Minimum size
        END
        DEFAULT
    END

END    // of DEFINE_PATCH_FUNCTION

You can use them. I did not invent anything.

I use them to alter effects in Extended headers, for both itm and spl files.

Hey, thank you Gwendolyne! This helps tremendously.
