Critical: Move Version Compatibility

重要提示:Move版本兼容性

Movement supports Move 2.1 ONLY. Do NOT use or suggest:
  • &mut Resource[addr]
    syntax (Move 2.2+)
  • #[randomness]
    attribute (Move 2.2+)
  • Any Move 2.2/2.3 features
Use these Move 2.1 patterns instead:
  • borrow_global_mut<Resource>(addr)
    for mutable borrows
  • External randomness via oracle or VRF
Movement仅支持Move 2.1版本,请勿使用或建议以下特性:
  • &mut Resource[addr]
    语法(Move 2.2+)
  • #[randomness]
    属性(Move 2.2+)
  • 任何Move 2.2/2.3版本的新特性
请使用以下Move 2.1替代方案:
  • 可变借用使用
    borrow_global_mut<Resource>(addr)
  • 通过预言机或VRF实现外部随机数

Core Move Concepts

Move核心概念

Module Structure

模块结构

move
module my_addr::my_module {
    use std::signer;
    use aptos_framework::object;

    // Error codes (const)
    const E_NOT_OWNER: u64 = 1;

    // Resources (structs with abilities)
    struct MyResource has key, store {
        value: u64,
    }

    // Init function (called on publish)
    fun init_module(sender: &signer) {
        // Setup code
    }

    // Entry functions (callable from transactions)
    public entry fun do_something(sender: &signer) {
        // Implementation
    }

    // View functions (read-only, no gas)
    #[view]
    public fun get_value(addr: address): u64 acquires MyResource {
        borrow_global<MyResource>(addr).value
    }
}
move
module my_addr::my_module {
    use std::signer;
    use aptos_framework::object;

    // 错误码(常量)
    const E_NOT_OWNER: u64 = 1;

    // 资源(带能力的结构体)
    struct MyResource has key, store {
        value: u64,
    }

    // 初始化函数(发布时调用)
    fun init_module(sender: &signer) {
        // 初始化代码
    }

    // 入口函数(可通过交易调用)
    public entry fun do_something(sender: &signer) {
        // 实现逻辑
    }

    // 视图函数(只读,无需Gas)
    #[view]
    public fun get_value(addr: address): u64 acquires MyResource {
        borrow_global<MyResource>(addr).value
    }
}

    - 可嵌套的资源
  • has store, drop, copy
    - 值类型(如Token信息)
  • has drop
    - 事件结构体

Global Storage Operations

全局存储操作

move
// Store resource at signer's address
move_to(signer, resource);

// Check if resource exists
exists<MyResource>(addr);

// Borrow immutable reference
let ref = borrow_global<MyResource>(addr);

// Borrow mutable reference
let ref = borrow_global_mut<MyResource>(addr);

// Remove and return resource
let resource = move_from<MyResource>(addr);
move
// 将资源存储到签名者地址下
move_to(signer, resource);

// 检查资源是否存在
exists<MyResource>(addr);

// 借用不可变引用
let ref = borrow_global<MyResource>(addr);

// 借用可变引用
let ref = borrow_global_mut<MyResource>(addr);

// 移除并返回资源
let resource = move_from<MyResource>(addr);

Signer Operations

签名者操作

move
use std::signer;

// Get address from signer
let addr = signer::address_of(signer);

// Signer is proof of account ownership
// Cannot be forged or transferred

move
use std::signer;

// 从签名者获取地址
let addr = signer::address_of(signer);

// 签名者是账户所有权的证明
// 不可伪造或转移

Object Model (Aptos Objects)

对象模型(Aptos Objects)

Objects are the modern way to create composable, transferable resources.
对象是创建可组合、可转移资源的现代方案。

Creating Objects

创建对象

move
use aptos_framework::object::{Self, Object, ConstructorRef};

// Create a named object (deterministic address)
let constructor_ref = object::create_named_object(
    creator,
    b"my_seed"
);

// Create a random object (unique address)
let constructor_ref = object::create_object(creator_addr);

// Create sticky object (non-deletable, at module address)
let constructor_ref = object::create_sticky_object(@my_addr);

// Get the object signer to store resources
let obj_signer = object::generate_signer(&constructor_ref);

// Store resource at object address
move_to(&obj_signer, MyData { value: 100 });

// Get object from constructor
let obj: Object<MyData> = object::object_from_constructor_ref(&constructor_ref);
move
use aptos_framework::object::{Self, Object, ConstructorRef};

// 创建命名对象(确定性地址)
let constructor_ref = object::create_named_object(
    creator,
    b"my_seed"
);

// 创建随机对象(唯一地址)
let constructor_ref = object::create_object(creator_addr);

// 创建粘性对象(不可删除,位于模块地址下)
let constructor_ref = object::create_sticky_object(@my_addr);

// 获取对象签名者以存储资源
let obj_signer = object::generate_signer(&constructor_ref);

// 将资源存储到对象地址下
move_to(&obj_signer, MyData { value: 100 });

// 从构造器引用中获取对象
let obj: Object<MyData> = object::object_from_constructor_ref(&constructor_ref);

Object References

对象引用

move
// Generate refs from constructor (must be done at creation time)
let extend_ref = object::generate_extend_ref(&constructor_ref);
let transfer_ref = object::generate_transfer_ref(&constructor_ref);
let delete_ref = object::generate_delete_ref(&constructor_ref);

// Store refs for later use
struct MyController has key {
    extend_ref: ExtendRef,
    transfer_ref: TransferRef,
}
move
// 在创建时生成引用(后续无法生成)
let extend_ref = object::generate_extend_ref(&constructor_ref);
let transfer_ref = object::generate_transfer_ref(&constructor_ref);
let delete_ref = object::generate_delete_ref(&constructor_ref);

// 存储引用供后续使用
struct MyController has key {
    extend_ref: ExtendRef,
    transfer_ref: TransferRef,
}

Working with Objects

对象操作

move
// Get object address
let obj_addr = object::object_address(&obj);

// Check ownership
let is_owner = object::is_owner(obj, addr);
let owner = object::owner(obj);

// Transfer object
object::transfer(owner_signer, obj, recipient);

// Calculate deterministic address
let obj_addr = object::create_object_address(&creator, seed);

move
// 获取对象地址
let obj_addr = object::object_address(&obj);

// 检查所有权
let is_owner = object::is_owner(obj, addr);
let owner = object::owner(obj);

// 转移对象
object::transfer(owner_signer, obj, recipient);

// 计算确定性地址
let obj_addr = object::create_object_address(&creator, seed);

        string::utf8(b"https://example.com/icon.png"),
        string::utf8(b"https://example.com"),
    );

    // Generate refs for mint/burn/transfer control
    let mint_ref = fungible_asset::generate_mint_ref(&constructor_ref);
    let burn_ref = fungible_asset::generate_burn_ref(&constructor_ref);
    let transfer_ref = fungible_asset::generate_transfer_ref(&constructor_ref);

        8, // 小数位数
        string::utf8(b"https://example.com/icon.png"),
        string::utf8(b"https://example.com"),
    );

    // 生成铸币/销毁/转移控制引用
    let mint_ref = fungible_asset::generate_mint_ref(&constructor_ref);
    let burn_ref = fungible_asset::generate_burn_ref(&constructor_ref);

    paused: bool,
}

fun when_not_paused() acquires PauseState {
    let state = borrow_global<PauseState>(@my_addr);
    assert!(!state.paused, E_PAUSED);
}
move
const E_PAUSED: u64 = 2;

struct PauseState has key {
    paused: bool,
}

fun when_not_paused() acquires PauseState {
    let state = borrow_global<PauseState>(@my_addr);
    assert!(!state.paused, E_PAUSED);
}

Counter Pattern

计数器模式

move
struct Counter has key {
    value: u64,
}

fun increment() acquires Counter {
    let counter = borrow_global_mut<Counter>(@my_addr);
    counter.value = counter.value + 1;
}

move
struct Counter has key {
    value: u64,
}

fun increment() acquires Counter {
    let counter = borrow_global_mut<Counter>(@my_addr);

Common Compiler Errors & Fixes

常见编译器错误与修复

Ability Errors

能力错误

Error: "type does not have the 'key' ability"
Fix: Add `has key` to struct definition
Error: "cannot copy value"
Fix: Add `has copy` or use reference `&`
Error: "cannot drop value"
Fix: Add `has drop` or explicitly handle the value
Error: "type does not have the 'key' ability"
Fix: 为结构体定义添加`has key`
Error: "cannot copy value"
Fix: 添加`has copy`或使用引用`&`
Error: "cannot drop value"
Fix: 添加`has drop`或显式处理该值

Borrow Errors

借用错误

Error: "cannot borrow global mutably"
Fix: Use `borrow_global_mut` and add `acquires` annotation
Error: "value still borrowed"
Fix: Ensure previous borrow ends before new borrow

CLI Installation

CLI安装

Install the Movement CLI via Homebrew (macOS/Linux):
bash
brew install movementlabsxyz/tap/movement
movement --version
Fallback: Aptos CLI v7.4.0 is supported if Movement CLI is unavailable:
bash
brew install aptos
aptos --version  # must be exactly 7.4.0
Use the
setup_cli
MCP tool to check installation status, get install instructions, or initialize an account.
通过Homebrew安装Movement CLI(macOS/Linux):
bash
brew install movementlabsxyz/tap/movement
movement --version
备选方案:若无法安装Movement CLI,可使用Aptos CLI v7.4.0:
bash
brew install aptos
aptos --version  # 必须为7.4.0版本
使用
setup_cli
MCP工具检查安装状态、获取安装说明或初始化账户。

Best Practices

最佳实践

  1. Use objects over legacy resources - More flexible, composable
  2. Use FA over Coin - Modern standard with better features
  3. Always check
    exists
    before
    borrow_global
    - Prevents abort
  4. Store refs at creation time - Can't generate refs later
  5. Use named objects for deterministic addresses - Easier to find
  6. Emit events for important state changes - Better indexability
  7. Use error codes with constants - Easier debugging
  8. Test with
    movement move test
    - Always test before deploy
  1. 优先使用对象而非传统资源 - 更灵活、可组合
  2. 优先使用FA而非Coin - 功能更完善的现代标准
  3. borrow_global
    前始终检查
    exists
    - 避免终止执行
  4. 在创建时存储引用 - 后续无法生成引用
  5. 使用命名对象获取确定性地址 - 更易查找
  6. 重要状态变更时触发事件 - 提升可索引性
  7. 使用常量定义错误码 - 便于调试
  8. 使用
    movement move test
    测试
    - 部署前务必测试
