[Question] Lua and passing array as function argument

[TheAifam5]

Hi,
I have problem, how to pass array (from LUA) to C++ function?
And how to get array size and items?

LUA:

srututuArray({0xDA8208, 0x13A8, 0x4, 0x0018})

Just write simple wrapper over std::vector like built-in Qt wrappers.

You can use LuaRef to capture the Lua value, something like the following:

void srututuArray(LuaRef list)
{
    for (int i = 1, n = list.len(); i <= n; i++) {
        int item = list.get<int>(i);
        ...
    }
}

or you can use Lua::getList to convert LuaRef to std::vector (or other list containers):

void srututuArray(LuaRef ref)
{
    std::vector<int> list = Lua::getList<std::vector<int>>(ref);
    ...
}

This seems to be resolved, please open new issue if you have more questions.
