形状 条形积木

The Set () to () 积木 is a 变量类积木 and a 条形积木. The block will set the specified 变量 to the given value: a 字串 or number. In Scratch 1.2.1 and earlier, only numbers could be entered.

Prior to Scratch 1.3, this block did not have a drop-down input listing the variables and instead there was an instance of it for each variable.

播放音效 [SpaceRipple v]
變數 [x v] 設為 [0]

  • Setting a value for a math formula
