multiply_temp_variableanynoneMultiplies a temp variable by a value, another variable, or a [math expression](script_math_expression.md).
### Examples
multiply_temp_variable = { num_dogs = 2 } multiply_temp_variable = { num_dogs = { value = num_cats add = 1 } }

multiply_temp_variable 常用于动态伤害/奖励计算场景，例如根据某个基础值乘以倍率得到最终结果，再赋予到国家或状态上。典型场景包括：按科技等级缩放生产加成、按人口比例计算征兵数量等。
# 计算最终援助物资数量 = 基础量 × 战争支持度系数
set_temp_variable = { var = aid_amount value = 500 }
set_temp_variable = { var = war_support_ratio value = ROOT.war_support }
divide_temp_variable = { var = war_support_ratio value = 100 }
multiply_temp_variable = { var = aid_amount value = war_support_ratio }
add_to_variable = { var = stored_aid value = aid_amount }
[set_temp_variable](/wiki/effect/set_temp_variable)：在做乘法之前必须先用它初始化临时变量，否则变量无初始值，乘法结果不可预期。[add_to_temp_variable](/wiki/effect/add_to_temp_variable) / [subtract_from_temp_variable](/wiki/effect/subtract_from_temp_variable)：乘法通常是多步算式的中间环节，前后往往需要加减操作来完成完整公式。[check_variable](/wiki/trigger/check_variable)：乘法计算完成后，常用此触发器检验结果是否落在合理区间，再决定后续分支逻辑。[clamp_temp_variable](/wiki/effect/clamp_temp_variable)：对乘法结果进行上下限截断，防止数值溢出或产生游戏性失衡。temp variable 仅在当前效果块执行期间存在，跨 event option 或跨 on_action 后就会消失，不要期望它在下一个触发点还保有乘法结果，需持久化时应改用 [set_variable](/wiki/effect/set_variable) 存到普通变量。set_temp_variable 赋值，其初始值为 0，任何数乘以 0 仍为 0，导致结果始终归零且极难排查——务必在乘法前确认变量已被赋予有效初始值。Hands-on notes are AI-generated and checked against the vanilla command vocabulary — treat them as a starting point, not authoritative reference.

multiply_temp_variable is commonly used in dynamic damage/reward calculation scenarios, such as computing a final result by multiplying a base value by a scaling factor, then assigning it to a country or state. Typical use cases include scaling production bonuses by technology level and calculating recruitment numbers based on population ratios.
# Calculate final aid quantity = base amount × war support coefficient
set_temp_variable = { var = aid_amount value = 500 }
set_temp_variable = { var = war_support_ratio value = ROOT.war_support }
divide_temp_variable = { var = war_support_ratio value = 100 }
multiply_temp_variable = { var = aid_amount value = war_support_ratio }
add_to_variable = { var = stored_aid value = aid_amount }
[set_temp_variable](/wiki/effect/set_temp_variable): You must initialize the temporary variable with this before performing multiplication, otherwise the variable has no initial value and the multiplication result becomes unpredictable.[add_to_temp_variable](/wiki/effect/add_to_temp_variable) / [subtract_from_temp_variable](/wiki/effect/subtract_from_temp_variable): Multiplication is typically an intermediate step in multi-step formulas, often requiring addition and subtraction operations before and after to complete the full calculation.[check_variable](/wiki/trigger/check_variable): After multiplication is complete, this trigger is commonly used to verify whether the result falls within a reasonable range before deciding on subsequent branching logic.[clamp_temp_variable](/wiki/effect/clamp_temp_variable): Apply upper and lower bounds clamping to the multiplication result to prevent numerical overflow or create gameplay imbalances.temp variable only exists during the execution of the current effect block. After crossing event option boundaries or on_action triggers, it disappears. Do not expect it to retain the multiplication result at the next trigger point. For persistent storage, use [set_variable](/wiki/effect/set_variable) to store the value in a regular variable instead.set_temp_variable, its initial value is 0. Any number multiplied by 0 remains 0, causing the result to always be zero and making it extremely difficult to debug. Always confirm the variable has been assigned a valid initial value before performing multiplication.
