类别 运算类积木
形狀 菱形积木

The () or () 积木 is an 运算类积木 and a 菱形积木. The block joins two boolean blocks so any one of them can be true to return true — if at least one of them is true, the block returns true; if neither of them are true, it returns false.

This block can be stacked inside itself — this can be used to fit more booleans inside.

用法示例

This script asks the user what their favorite color, and will give one response if it is "blue" or "red", and another response if it is anything else.

當 @greenflag 被點擊
詢問 [What is your favorite color?] 並等待
如果 <<(詢問的答案) = [blue]> 或 <(詢問的答案) = [red]>> 那麼 
  說出 [I also like that color!]
否則
  說出 [That's a nice color!]
end

Workaround

Main article: List of Block Workarounds


This block can be replicated with the following code:

<<<<condition1> 不成立> 且 <<condition2> 不成立>> 不成立>

This stack also works (with the 变量 T/F being the result):

變數 [T/F v] 設為 [false]
如果 <condition1> 那麼 
  變數 [T/F v] 設為 [true]
end
如果 <condition2> 那麼 
  變數 [T/F v] 設為 [true]
end
