- respec: the panel's unused second button array becomes − buttons between name and value; attributes give back invested points, skills give back skill points, a level-1 skill is removed and can be chosen anew; all through the game's own point functions (protected copy stays in sync) - the − is the + icon with its vertical arm covered (no minus image exists) - hud: RenderCentred / HandleCentred for mods hooking centred windows; mouse event helpers shared in game/ui/events.h Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

# Taking back attribute and skill points (mods/respec.cpp)
|
||
|
||
Request of 2026-10-16: a − button on each row of the character panel
|
||
(inventory, Attribute / Fertigkeiten) gives back one invested point. A skill
|
||
at level 1 is removed and a new one can be chosen in its place.
|
||
|
||
## Data (cCreatureArts, hero +0x3a8, measured 2026-10-16)
|
||
|
||
| Offset | What |
|
||
|---|---|
|
||
| +0x1c[6] | attribute points invested, in panel order (Stärke, Widerstand, Geschick, Physische Reg., Mentale Reg., Charisma); the shown values add class and level growth |
|
||
| +0x23 | free attribute points (index 7 of the same array) |
|
||
| +0x24[8] | skill id per row (0: empty) |
|
||
| +0x2c[8] | bought skill level per row (a chosen skill starts at 1) |
|
||
| +0x34[8] | skill levels from items |
|
||
| +0x42 | free skill points |
|
||
| +0x44 | new skills still to choose |
|
||
| +0x56 | highest skill level allowed |
|
||
|
||
Game functions (all on cCreatureArts):
|
||
|
||
- `0x5a03a0 (index, delta)` adds to an attribute byte; the + does (row, 1)
|
||
then (7, −1), then `0x579560 (0, 1)` recalculates the hero (0x580d50).
|
||
- `0x582360 (row, delta, spend)` adds skill levels; with `spend` it takes them
|
||
from the free skill points (a negative delta gives them back).
|
||
- `0x580fe0 (skill)` puts a chosen skill into the first empty row at level 1
|
||
and uses up one choice; `0x580f30` lists the skills still choosable.
|
||
|
||
Each of them also writes the hero's +0x3b0.. block, xor-ed, into a protected
|
||
page (0x182cddc / 0x182cde0). Changing the fields directly without that made
|
||
the hero's life show 0. The mod therefore only changes fields through these
|
||
functions; after removing a skill it calls `0x582360 (row, 0, 1)` to refresh
|
||
the copy.
|
||
|
||
## Panel (cUI_StatisticsChar, vtable 0x8942d8)
|
||
|
||
- +0x164 bit 0x10: attributes shown (else skills); +0xf84: choosing a new
|
||
skill.
|
||
- +0x2cc: the 8 + buttons (cUI_Button, 0xbc bytes each, laid out by 0x6ac120:
|
||
x 232, rows 19 px apart from y 72, 16×16).
|
||
- +0x8ac: a second array of 8 buttons that the game constructs and destroys
|
||
but never lays out or uses. These are the − buttons now.
|
||
- The panel renders while hidden (inventory closed); the − buttons check its
|
||
visible flag.
|
||
|
||
cUI_Button images (render 0x72af90): normal at +0x64 (u0, u1, v0, v1) with
|
||
texture +0x84, pressed at +0x54 / +0x80. Image descriptors are static, 0x54
|
||
bytes each (texture +0x28, pixel rect +0x2c..+0x38, converted to UVs at
|
||
start-up). The + uses 0x9ed2d0 (pressed 0x9ed324) in UI atlas 0x26a. The
|
||
names UI_BUTT_MINUS_UP/DW are registered, but neither UI atlas (0x26a, 0x289;
|
||
both drawn whole once and looked at) has a minus image. The − is therefore
|
||
the + with the vertical arm of its cross covered by two grey patches,
|
||
measured from a screenshot: arm x 6.5..8.8, y 4.0..6.9 and 9.0..11.5 in icon
|
||
pixels.
