Class Documentation
Edit documentationA game calculation: a named formula that returns one float, built from
calculation parts. Calculations live in maps keyed by
name, such as SpellDataResource.mSpellCalculations, ItemData.mItemCalculations and
PerkScriptData.mCalculations. Tooltips reference a calculation by that name, and the
client evaluates it to print the number and its breakdown. Some classes hold a
calculation directly, such as TargeterDefinitionAoe.DynamicGameCalcSizeScalar.
Evaluation context
The client evaluates a calculation with a context that every part reads:
| Input | Meaning |
|---|---|
| caster | The unit whose stats, ability resources, buffs, items and champion level the parts read. |
| target | An optional second unit. Only parts with UseTargetStats read it. The tooltip does not pass a target, so those parts read the caster there. |
| owner | The object that holds the calculation: a spell or an item. Named data values, effect amounts and other calculations are looked up on it. |
| spell slot | The slot of the spell. Cooldown parts read it. |
| spell level | The index into the data values of the owner. |
Named data values
A part that names a data value, such as
NamedDataValueCalculationPart, asks the owner
for the value with that name at the spell level. For a spell, the owner is its
SpellDataResource: the client first reads the override
that the current game mode defines for that name, then mDataValues, and returns the
entry at the spell level. A name that the owner does not have gives 0. The spell
level is not checked against the length of the value list.
Value and base value
Every part has a current value and a base value. The base value leaves out
the changes that the caster's spell modifiers make. When the two differ for a part, or
its coefficient differs from its base coefficient, the tooltip marks the part as
modified with the GlobalStatsUIData style tag 0x745e38b2.
Tooltip display modes
mSimpleTooltipCalculationDisplay and mExpandedTooltipCalculationDisplay select how
the tooltip prints the calculation. The client uses the expanded field when the tooltip
is in its expanded mode, and the simple field otherwise.
| Value | Name | Tooltip text |
|---|---|---|
0 |
ExpandedPartsWithFinalTotals |
The value of each part. |
1 |
ExpandedPartsWithCoefficients |
The coefficient of each part, as a percentage if mDisplayAsPercent is set. |
2 |
ExpandedPartsWithCoefficientsAsPercent |
The coefficient of each part, as a percentage for scaling parts and when mDisplayAsPercent is set. |
3 |
ExpandedPartsWithTotalsAndCoefficients |
The value and the coefficient of each part. |
4 |
ExpandedPartsWithPercentCoeffAndFinalTotal |
The parts as in mode 2, then the total of the calculation. |
5 |
CombinedValue |
The total of the calculation only. |
6 |
CombinedWithScalingIcons |
The total of the calculation, with the icon of each part. |
7 |
MultiplierAsPercent |
The multiplier of a GameCalculationModified times 100, with no decimals. Any other calculation prints an error text. |
8 |
UseDefault |
The mode that GlobalStatsUIData sets: mTooltipCalculationExpansion for the simple field, mExpandedTooltipCalculationExpansion for the expanded field. |
The total in modes 4 to 6 uses the modified style tag when the value differs from
the base value.

DamageType
U32 15.20
Damage type of the calculation. Purpose not yet identified: calculation evaluation and the tooltip text do not read it.
ResultModifier
U8 Rounding or transform that the client applies to the final value, after the parts are added.
| Value | Name | Result |
|---|---|---|
0 |
kNone |
The value is not changed. |
1 |
kSquareRoot |
An approximate square root. Values of 0 or below are not changed. |
2 |
Floor |
Rounds down. |

mExpandedTooltipCalculationDisplay
U8 Tooltip display mode of the calculation in the expanded tooltip. See the display mode table in the class description.
mMultiplier
Pointer<IGameCalculationPart> A part whose value multiplies every part of the calculation. The client evaluates it
first, with the same context, and multiplies each part value by it before the parts
are added. Unset, the multiplier is 1.
mSimpleTooltipCalculationDisplay
U8 Tooltip display mode of the calculation in the simple tooltip. See the display mode table in the class description.
tooltipOnly
Bool Purpose not yet identified. Calculation evaluation and the tooltip text do not read it.
