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

Usage tips

• Infra type: CPU
• Common nodes: unknown
