以下是您提供的代码的中文翻译，保留了源代码：

function custom_is_in_casino()
    local ped = PlayerPedId() -- 获取玩家角色的ID
    local casino_coords = vec3(0.0, 0.0, 0.0) -- 赌场的位置
    local dist = #(casino_coords - GetEntityCoords(ped)) -- 计算赌场与玩家之间的距离

    if dist < 10.0 then -- 如果距离小于10.0
        return true -- 玩家在赌场内
    else
        return false -- 玩家不在赌场内
    end
end

在这个代码中，`custom_is_in_casino` 函数用于判断玩家是否在赌场内。代码应该放在 `Client.lua` 中，因为它涉及到玩家的客户端信息和位置。
