多个If表达式出现MAXSCRIPT错误

Question

我已经开始学习Maxscript了，现在我遇到了困难，如果是单个对象并且如果它超过1，则让标签将对象的数量显示为字符串。

但我总是犯错误。。。知道吗？

group "Current Selection:" 
(
label lbl_01 "Nothing Selected"
)

---------------------------------------------------------------------------------------------------------------//电流选择功能

fn letmeknow obj= 
(       
    local contador = (selection.count as string)
    if selection.count != 0 then  
    (
        lbl_01.text = ("Name: " + obj.name) 
    )
    else 
    (
        lbl_01.text = "Nothing Selected" 
    )
    if selection.count >= 2 do (lbl_01.text = ("Objects: " + contador))
)   

Answer 1

问题似乎不在您提供的代码范围内，如果看不到代码的其余部分，很难判断。无论如何，这里有一个使用case表达式而不是多个if的工作示例：

rollout test "Test"
(
    group "Current Selection:" 
    (
        label lbl_01 "Nothing Selected"
    )
    button btnTest "Test"
    fn getSelectionString = 
    (
        case selection.count of
        (
            0 : "Nothing Selected"
            1 : "Name: " + selection[1].name
            default : "Objects: " + selection.count as string
        )
    )
    on btnTest pressed do
        lbl_01.text = getSelectionString()
)
createDialog test
