- Class name: DF_Logic_node
|

- Category: Derfuu_Nodes/Functions
|
|
- Output node: False

LogicNode节点执行基本逻辑运算，如比较操作（大于、小于、等于）和布尔运算（与、或、异或）。它通过评估条件并根据指定的逻辑确定结果，从而抽象地支持决策过程。

# Input types
|
|
## Required
|
|
- Operation
|
|
- 指定要执行的逻辑运算，包括比较和布尔运算，决定了CompareValue_A和CompareValue_B之间应用的逻辑。
|
|
- Comfy dtype: COMBO[STRING]
|
|
- Python dtype: str
|
|
- CompareValue_A
|
|
- 用于比较或逻辑运算的主要值。
|
|
- Comfy dtype: *
|
|
- Python dtype: object
|
|
## Optional
|
|
- CompareValue_B
|
|
- 用于比较或逻辑运算的次要值，与CompareValue_A一起用于评估指定的Operation。
|
|
- Comfy dtype: *
|
|
- Python dtype: object
|
|
- OnTrue
|
|
- 如果逻辑运算结果为真时返回的值。
|
|
- Comfy dtype: *
|
|
- Python dtype: object
|
|
- OnFalse
|
|
- 如果逻辑运算结果为假时返回的值。
|
|
- Comfy dtype: *
|
|
- Python dtype: object
|
|
|
|
# Output types
|
|
- *
|
|
- 逻辑运算的结果，可以是OnTrue或OnFalse值，具体取决于运算的结果。
|
|
- Comfy dtype: *
|
|
- Python dtype: object
