The () of () 积木 is a 侦测类积木 and a 椭圆形积木. The block will report a specified value of the specified 角色 or the 舞台.
Below are the values that can be reported:
用法示例
This block allows sprites and the Stage to have access to other sprites' special values. With this, 专案 can have a lot of connectivity between sprites.
This block renders eight blocks unnecessary:
Also, as of Scratch 1.4, the SpriteName area can have an expression/variable put into it so that a script can access any other sprite's variables or properties given that sprite's name. This is useful in projects where one wants to be able to generalize things:
變數 [index v] 設為 [0] 重複 (清單 [names v] 的項目數 :: list) 次 變數 [index v] 改變 (1) 替換第 (index) 項於 [values v] 成 ([myVar v] \( (清單第 (index) 項項目\( [names v] \) :: list) \)) end
Some common uses for the () of () block:
- Making a sprite follow another by setting their X and y 座標s to the X and y 座標s of the other, plus or minus a certain amount:
當 @greenflag 被點擊 重複無限次 定位到 x: (([x 座標 v] \( [角色2 v] \)) - (10)) y: (([y 座標 v] \( [角色2 v] \)) - (10)) end
- Waiting for a different sprite to reach a certain costume
等待直到 <([造型編號 v] \( [角色2 v] \)) = (target)>
- Checking volume to adjust a sprite's own volume accordingly
音量設為 ([音量 v] \( [角色2 v] \)) %
