# 文本（TextUI）

## ⚙️ 如何更改 QBCore 的默认**文本**

> 本节将教你如何将 `QBCore` **默认文本** 替换为 `ak-lib` **文本**。
>
> 由于 `QBCore` 不同版本在函数结构上略有差异，本次示例基于 `QBCore` `1.3.0` 进行讲解。

***

### 🧭 步骤一：导航到函数文件

前往以下路径：

```
qb-core\client\drawtext.lua
```

***

### 🧩 步骤二：替换 QBcore 整个文本函数内容

```lua
local QB_CORE_TEXTUI_ID = "qb-core-default"

local function convertPosition(qbPosition)
    if not qbPosition or type(qbPosition) ~= 'string' then 
        return 'middle-left'
    end
    local positionMap = {
        ['left'] = 'middle-left',
        ['right'] = 'middle-right',
        ['top'] = 'top-center',
        ['bottom'] = 'bottom-center',
        ['center'] = 'middle-center'
    }
    if positionMap[qbPosition] then
        return positionMap[qbPosition]
    end
    return qbPosition
end

local function hideText()
    exports['ak-lib']:HideTextUI(QB_CORE_TEXTUI_ID)
end

local function drawText(text, position)
    if not text then return end
    local akPosition = convertPosition(position)
    exports['ak-lib']:TextUI({
        id = QB_CORE_TEXTUI_ID,
        message = text,
        position = akPosition,
        duration = 0,
    })
end

local function changeText(text, position)
    if not text then return end
    local akPosition = convertPosition(position)
    local isOpen, _ = exports['ak-lib']:IsTextUIOpen(QB_CORE_TEXTUI_ID)
    if isOpen then
        exports['ak-lib']:UpdateTextUI({
            id = QB_CORE_TEXTUI_ID,
            message = text,
            position = akPosition
        }, QB_CORE_TEXTUI_ID)
    else
        drawText(text, position)
    end
end

local function keyPressed()
    CreateThread(function()
        Wait(500)
        hideText()
    end)
end

RegisterNetEvent('qb-core:client:DrawText', function(text, position)
    drawText(text, position)
end)

RegisterNetEvent('qb-core:client:ChangeText', function(text, position)
    changeText(text, position)
end)

RegisterNetEvent('qb-core:client:HideText', function()
    hideText()
end)

RegisterNetEvent('qb-core:client:KeyPressed', function()
    keyPressed()
end)

exports('DrawText', drawText)
exports('ChangeText', changeText)
exports('HideText', hideText)
exports('KeyPressed', keyPressed)

```
