Computercraft Lua循环嵌套if场景goto跳转报'=' expected near 'continue'错误

报错根因 #

• 核心语法错误来自goto目标标签拼写不匹配：代码中跳转语句写为goto contine，比实际定义的::continue::标签少了字母u，Lua解析器无法识别为合法跳转指令，误以为你调用了不存在的continue关键字，因此抛出'=' expected near 'continue'错误。
• 额外存在的语法问题：代码末尾多余了end关键字，repeat...until结构不需要额外的end闭合；终止条件fe > 100和你预期的fe≥100停止逻辑不符；else分支二次读取用户输入后未做校验，存在传入非法值的风险。

修正后完整代码 #

motor = peripheral.wrap("right")
local fe = 0 -- 初始化fe变量避免首次循环判断报错

repeat 
    local RPM = motor.getSpeed()
    print("current rpm is ", RPM, "RPM. What RPM do you need?")
    local setrpm = tonumber(io.read())
    if type(setrpm) ~= "number" then
        print("Must be a number between -256 and 256")
        goto continue
    end
    -- 数值合法才执行设置和输出逻辑
    motor.setSpeed(setrpm)
    local currentRpm = motor.getSpeed()
    local su = currentRpm * 16
    fe = motor.getEnergyConsumption()
    print("You have set speed " , currentRpm, " RPM")
    print("Current stress cap is now ", su, "SU")
    print("Power Consumption is now ", fe, "FE/t")
::continue::
until(fe >= 100)
