为什么我的 Lua 脚本无法在 Roblox Studio 中运行

Question

我一次又一次地尝试让这段代码正常工作。

-- Sample assembly code with labels

local assemblyCode = [[

    LOAD R1, 10

    STORE R1, 20

    ADD R1, 30

    SUBTRACT R2, 40

    JUMP_IF_ZERO R1, LOOP

    HALT

LOOP:

    ADD R2, R3

    JUMP LOOP

]]

-- Mapping of assembly mnemonics to opcodes

local opcodeMappings = {

    ["NOOP"] = 0,

    ["LOAD"] = 1,

    ["STORE"] = 2,

    ["ADD"] = 3,

    ["SUBTRACT"] = 4,

    ["JUMP"] = 5,

    ["JUMP_IF_ZERO"] = 6,

    ["COMPARE"] = 7,

    ["MULTIPLY"] = 8,

    ["DIVIDE"] = 9,

    ["LOGICAL_AND"] = 10,

    ["LOGICAL_OR"] = 11,

    ["SHIFT_LEFT"] = 12,

    ["SHIFT_RIGHT"] = 13,

    ["HALT"] = 14,

    ["MOV"] = 15,

}

-- Mapping of register mnemonics to register numbers

local registerMappings = {

    ["R1"] = 0,

    ["R2"] = 1,

    ["R3"] = 2,

}

-- Process and assemble the code

function assemble(assemblyCode)

    local assembledCode = {}

    local labelTable = {}

    for line in assemblyCode:gmatch("[^\r\n]+") do

        local parts = {}

        for part in line:gmatch("%S+") do

            table.insert(parts, part)

        end

        if #parts > 0 then

            local mnemonic = parts[1]:upper()

            if mnemonic:sub(-1) == ":" then

                local label = mnemonic:sub(1, -2)

                labelTable[label] = #assembledCode + 1

            else

                local opcode = opcodeMappings[mnemonic]

                if opcode then

                    local instruction = opcode * 32

                    if opcode == 0 then

                        -- NOOP

                    elseif opcode >= 1 and opcode <= 15 then

                        if opcode == 15 then

                            -- MOV

                            local srcRegister = registerMappings[parts[2]:upper()]

                            local destRegister = registerMappings[parts[3]:upper()]

                            if not srcRegister or not destRegister then

                                error("Invalid register in MOV instruction.")

                            end

                            instruction = instruction + (srcRegister * 4) + destRegister

                        else

                            local register = registerMappings[parts[2]:upper()]

                            local operand = tonumber(parts[3])

                            if not register or not operand then

                                error("Invalid register or operand.")

                            end

                            instruction = instruction + (register * 32) + operand

                        end

                    else

                        error("Invalid opcode: " .. mnemonic)

                    end

                    table.insert(assembledCode, instruction)

                else

                    error("Unknown mnemonic: " .. mnemonic)

                end

            end

        end

    end

    -- Replace label references

    for i, instruction in ipairs(assembledCode) do

        if type(instruction) == "string" then

            local label = instruction

            local labelAddr = labelTable[label]

            if not labelAddr then

                error("Label not found: " .. label)

            end

            assembledCode[i] = labelAddr

        end

    end

    return assembledCode

end

-- Assemble the code

local assembledCode = assemble(assemblyCode)

-- Display the assembled machine code

for _, instruction in ipairs(assembledCode) do

    if type(instruction) == "number" then

        print(string.format("0x%04X", instruction))

    else

        print(instruction .. ":")

    end

end

我尝试让 ChatGPT 修复它，但它不起作用。它的目的是将翻译后的指令打印到控制台（将在其他地方使用它），但它不断出现我实现为 Workspace.Script:77: Invalid register or operand 的寄存器错误。我正在使用提供的示例代码运行它，欢迎任何帮助。

我是用Lua而不是Luau写的，最后我不得不重写整个事情
