How To Call ToString () methods from Lua?

HI,
I am trying to do something like this:

Debug.Log ("Object position: " .. self.go.transform.position);

to print the position of my gameobject, however it is trying to concatenate the actual Vector3 to "Object position: ", as opposed to the ToStringed version of the vector3.

Slua also can not seem to find the ToString methods if I try "Debug.Log ("Object position: " ... self.go.transform.position.ToString ()), or position:ToString().

The only way I am able to print the vector normally is Debug.Log (self.go.transform.position). print(self.go.transform.position) just prints the memory/table address as well, which is not desired.

Is there anyway to grab the ToString from a c# script/object member?

EDIT: Larger question: How do I access (or generate code for) the System namespace/functions from LuaJit so that I can use System.* classes?

当lua脚本有语法错误的时候，无法显示错误信息和行数

执行：

local a = －1

期望报错：

lua: test.lua:2: unexpected symbol near char(239)

实际报错：

attempt to concatenate a nil value

strict.lua check failed when debugging with DebugInterface。

We are using strict.lua to check if any global is used without declaration.

SLuaDebug.cs line 107 fails the check.

local function buildEnv()
        local localEnv = setmetatable({}, {__index=_G})
        local setVariable = _G  --local keyword should be added
...

BTW How about debugging lua with zeroBrane ？

conflict slua with UNetWeaver in Unity 5.2.x

I see this issue http://www.unityqa.com/?/article/5 and i was suffered same issue at post.

when i attempt to upgrade unity 5.2.2, if Assembly-CSharp.dll or Assembly-CSharp-fistpass.dll size is much big, this issue is occured. ( but information is lack and uncertain )

I think this issue is only caused by UNetWeaver. because this option is not possibly switched turn on-off in unity, in addition, UNetWeaver use too many reflection for making inner structure.

but our project need fast workaround solution, then choose below it.

commit list in our project.
- rename base folder structure -> thing-nacho@360fec6
then change generated code path ( Only UnityEngine codegen ) for reduce Assembly-CSharp.dll binary size.
- https://github.com/thing-nacho/slua/blob/305d749b4ac5521fd051ec33ed87056317ddb193/Assets/Slua/Editor/LuaCodeGen.cs#L152
Operating SLua in plugin folder make possible, change class accessor and treat misc problem

i don't hope to accept my solution.
this issue only suggestion for sharing necessity that Assembly-CSharp.dll binary size must be reduced.

thanks.

coroutine.resume crash unity

test.lua

local x = nil

main.lua

function main()
    local co
    co = coroutine.create(function()
        LuaTimer.Add(1000, function()
            coroutine.resume(co)
        end)

        coroutine.yield()

        dofile "test"
    end)
    coroutine.resume(co)
end

Need export UnityEvent with more than one argument

We have some UnityEvent with more than one argument.
As follows

    public class ListViewEvent : UnityEvent<int,string> {

    }

SLua seems to only support those with only one argument

    static public void reg(IntPtr l) {
        LuaUnityEvent_int_string.reg(l); // <-- compiler complains about this line
        getTypeTable(l,"UIWidgets.ListViewEvent");
        createTypeMetatable(l,constructor, typeof(UIWidgets.ListViewEvent),typeof(UnityEngine.Events.UnityEvent<System.Int32,System.String>));
    }

引用类型属性设置为null时候报参数错误bug.

C#
class RTSCamera{
public LuaFunction onMoveFinish;
}

lua
RTSCamera.onMoveFinish=nil

会报参数类型不匹配错误

你好您的slua是针对热更新的吗？ is your slua created specifically for the hot update?

我看LuaCodeGen里面，是用file.WriteLine()来写入.
这导致利用mac生成的Custom class和利用win生成的custom class由于换行符的不同而产生冲突。
这在跨平台svn协作的时候产生比较大的问题。
是否改成统一的endline比较好呢？
比如
file.WriteLine(fmt) == >file.Write(fmt); file.Write("\r\n");

UnityEngine导出文件放到Plugins后会引起扩展方法找不到的问题

例如对Sprite定义了一些扩展方法放到文件 SpriteExt.cs 中。

这个SpriteExt.cs是在Assembly-CSharp中的,而Lua_UnityEngine_Sprite是在Assembly-CSharp-firstpass中，引用不到SpriteExt.cs

Issues with variable args number

Overloaded methods with different args number and params used comparison number of args, instead of matchType or something else.
Reproduce example:
public void func6(string str, params object[] args) {}
public void func6(string str, int a, params object[] args) {}
Overloaded methods with params argument handled with matchType as plain array. As result, caused 'No matched override function to call' error.
Reproduce example:
public void func6(string str, params object[] args) {}
public void func6(int a, params object[] args) {}

Can not work at 4.5.3f3

Hi, I tried slua, but it seems doesn't work at Unity 4.5.3f3, because this version lack UnityEngine.UI, how can I get it work?

Slua.Class not work correctly.

Take a example, a snap of code in main.txt:

-- test inherite class
local mv = My2(1, 2, 3)
local mv_2 = My2(4, 5, 6)      -- I add for test.
mv:Normalize()
mv_2:Normalize()       -- I add for test.
print("mv norm:", mv.x, mv.y, mv.z)      -- I modified for test.
print("mv_2 norm:", mv_2.x, mv_2.y, mv_2.z)      -- I add for test.
mv:Set(10, 20, 30)      -- I modified for test.
mv_2:Set(40, 50, 60)      -- I add for test.
print("mv:", mv.x, mv.y, mv.z)      -- I add for test.
print("mv_2:", mv_2.x, mv_2.y, mv_2.z)      -- I add for test.

will output:

mv norm:    0.62469504755442    0.78086880944303    0.93704257133164
mv_2 norm:    0.62469504755442    0.78086880944303    0.93704257133164
mv:    40    50    60
mv_2:    40    50    60

You will find the value of vector is always replaced by the last instance of the class.
That's because the code classfunc in Helper.cs:

local getmetatable=getmetatable
local function Class(base,static,instance)

    local mt = getmetatable(base)

    local class=static or {}
    setmetatable(class, 
        {
            __call=function(...)
                local r = mt.__call(...)
                local ret = instance or {}
                ret.__base=r

                local ret = setmetatable(ret,{
                    __index=function(t,k)
                        return r[k]
                    end,

                    __newindex=function(t,k,v)
                        r[k]=v
                    end,
                })

                return ret
            end,
        }
    )
    return class
end
return Class

Once you used NewCls = Slua.Class(BaseCls, xxx, xxx), the ret is created and will not change any more, but when creating a new instance, the metatable of ret is set to the last instance of NewCls, and then being returned, but in this case, ret should never be modified anyway. So that's why it always output value of the last instance.

Got a SIGABRT while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries 
used by your application.

不支持 lua 5.2

Suggestions of DebugInterface

Can DebugInterface's debug addr and port be configurated？
Can DebugInterface be disable and enable at runtime?

A few words about the suggestions, We would like to have DebugInterface be complied with our releasing game (as the last solution to save our ass), but we don't want it be enabled every time, it would be enabled when needed only.
We have developed some games with cocos, we have developed a similar debugger like DebugInterface, here is how we handles:

Read debug addr and debug port from a config at persistentDataPath
If debug addr and port exist then starts the debugger.

Lua环境下无法判断已经销毁的对象是否为null

一个GameObject 被Destroy 后，由于LUA环境下 userdata ~= nil，即使对象销毁也无法知晓；

如果要自己导出函数判断的话不如加到slua库里吧

Request Filter for LuaCodeGen

Hi there
Can user filter out the unity classes or namespaces are not needed(eg, VR), when generating binding code.

关于第三方dll动态库链接的问题

比如我要编译一个 3rd.dll，它依赖的 libs = [lua51.lib]
其中lua51.lib是luajit项目编译出来的

因为slua在make的时候把lua51.dll改名为了slua.dll放到项目里，但这个改名似乎会导致3rd.dll找不到依赖。
试过几种方案：

把slua.dll名字改为lua51.dll,并对应修改dllimport的名字,则可以正常工作。
把lua51.lib重命名成slub.lib,再link出3rd.dll,依然无法工作。
直接修改msvcbuild.bat里的LJLIBNAME = slua.lib,进行编译，则可正常工作。

不知道关于这个问题,@pangweiwei 你怎么看？

C# Events and Delegates

Thank you for your response to my other posts.

I was wondering if SLua supported subscribing to C# events? I can see why this might be difficult/impossible, but wanted to see if you had any solution?

I knwo you mentioned to use delegates directly, but I'm not sure if you mean your Lua delegates or C# delegates? If c# do you mean anonymous delegate? How do I access the += and -= operators to register/deregister my Lua listener? A simple example would be awesome.

Thanks!

Lua3rdDLL.open(L) takes about 1.3 sec but doing nothing

I notice in file LuaSvr.cs function doinit(), calls to Lua3rdDLL.open(L) take about 1.3 sec but doing nothing and GC alloc goes up to 37mb
Seems the code as follows cause the problem.

var csfunctions = assembly.GetExportedTypes()
                    .SelectMany(x => x.GetMethods())
                        .Where(y => y.GetCustomAttributes(typeof(LualibRegAttribute),false).Any())
                        .ToList();

Any Idea ? Thanks !

Unity打包版本Mono内存泄漏问题（无论是windows版本还是设备版本）

现象：在Editor中运行正常，ObjectCache中的垃圾都会被回收掉，但是打包后运行版本ObjectCache中的已经被Destroy的UnityEngine.Object不会被垃圾回收，导致Mono用到的内存会越来越高。
截图1：

多次点击GC后，截图2：

可以看到，正常的object已经被gc，但是为null的UnityObject未被释放。

原因：Unity Editor中跟正常运行的打包版本，UnityEngine.Object处理不同，在UnityEditor中，当一个UnityObject被释放后，调用 GetHashCode()方法还是可以取到正确的值（释放的不是很彻底），但是打包版本调用此方法时，返回的是0

解决方法：ObjectCache修改objMap的Dictionary比较器

        public class ObjEqualityComparer : IEqualityComparer<object>
        {
            public bool Equals(object x, object y)
            {

                return ReferenceEquals(x, y);
            }

            public int GetHashCode(object obj)
            {
                return RuntimeHelpers.GetHashCode(obj);
            }
        }

        Dictionary<object, int> objMap = new Dictionary<object, int>(new ObjEqualityComparer());

这个bug我们找了整整2天，测试代码无法上传，自己修改Dictionary<object, int> objMap为public，写个监控即可。

LuaSvr.init线程池与Resources.LoadSync冲突问题

Unity 4.6.4

如果在LuaSvr.init之前，使用了Resources.LoadAsync函数，会导致init里的线程池执行到一半没有继续，然后导致Editor卡住，内存不停的增加，最后崩溃。

Resources.LoadAsync(uixxxxx)

后面再进行

LuaSvr.init(null, ()=>{
     onFinishInit();
});

经排查，发现线程池执行的函数doBind执行到一定情况，然后就没执行到最后100%

可能两个情况：

doBind中某函数大量alloc，导致Editor崩溃(从任务管理器中可知内存在不停递增)
线程池执行的doBind被停掉了

LuaSvr cannot add custom native lib registration before call it's `main` function

I compile a custom native lua lib A into slua plugin.
When I use LuaSvr("xxx"), it call the file's "main" function to start, but inside the function there's code depends on the lib A. I need to register the A lib after luastate created and before the main function execution. But there's no way to achieve this with LuaSvr right now. I think it could provide an option whether to call the main function in the LuaSrv contructor.

Also I could workaround by manually create LuaState and do the bind stuff LuaSrv does to insert my custom register code, or leave 'main' function empty and call another real main later. But I don't think it's a good design.

Please take a consider about that.

[help]OSX built slua bundle doesn't work properly on Unity5.0

course LuaDLL.luaL_newstate() return null. the prebuilt slua.bundle from git works right.

my slua.bundle xcode project compile slua.c and link with just built libluajit_x86.a and libluajit_x86_64.a to generate the universal bundle. is there any specific build settings need to apply?

I build the luajit using following script:

cd luajit
make clean
make CC="gcc -m32" BUILDMODE=static
cp src/libluajit.a ../osx/libluajit_x86.a

make clean
make CC="gcc" BUILDMODE=static
cp src/libluajit.a ../osx/libluajit_x86_64.a

another hint is I found my slua.bundle(nearly 1M) much bigger than prebuilt one from git(397k)

editor切出run状态的时候，OnDestroy里若调用lua代码会导致editor crash

c#:

Class A :MonoBehaviour{
    public Delegate delegate

    void OnDestroy(){
        delegate()
    }
}

lua:

local a = gameobject:GetComponent(A)
a.delegate = {'+=',function(){

}}

以上这种情况，Editor停止Run状态的时候会调用OnDestroy,然后有几率导致Editor Crash.

slua应该避免unity crash

很多情况下，预设修改后，点apply并不会立即保存到硬盘上，而是unity3d退出的时候才存盘。当unity3d crash的时候，预设修改就不会存盘而直接丢失。

所以建议slua应该避免unity crash.

参数为Vector3[]时候类型匹配不上

EG：C#
class Helper{
//重载方法中有数组
public static void move(GameObject obj,Vector3[] paths,float t){}
//有重载方法
public static void move(GameObject obj,Vector pos,float t){}
}
上面的函数会调用不了
lua
local paths={}
table.insert(paths,Vector3(0.1,1,0))
table.insert(paths,Vector3(1.1,1,2.3))
Helper. move(go,paths,1)

报错 No matched override function to call

Pass binary string from c# to lua

c# code:

    byte[] bytes = {0,0,0,0};
    string str = System.Text.Encoding.UTF8.GetString(bytes);
    callback(str);

lua code:

    callback = {'+=',function ( str )
        print(string.len(str))
    end}

The length of str received in lua is 0.

I have googled it and got an answer:
http://stackoverflow.com/questions/3722060/passing-a-c-sharp-byte-array-to-luainterface

Finally traced it down to a the call to ::lua_pushstring() in lapi.c. It called strlen() on the char* passed in. Since my first byte of data was 0, it returned 0. There is an alternate call, lua_pushlstring, that accepts the size of the string as an argument. Changing to call this function fixed the issue.

Is there a way to handle exception from doString()?

I coded something like this:

Lua = new LuaSvr();
Lua.init(null, LoadLuaComplete, false);
try
{
Lua.luaState.doString("someUncaughtException()", "chunkName");
}
catch (Exception e)
{
Debug.Log(e.message);
}

But it cannot caught an error in lua. What should I do?

lua string include zero bytes cannot pass to function receive byte[] parameter

in C#

void foo(byte[]) {
}

// binding code is
MyType self=(MyType)checkSelf(l);
System.Byte[] a1;
checkType(l,2,out a1);
self.foo(a1);

it doesn't work because no string to byte[] conversion allowed directly.

so I have to write my own MonoPInvoke function like:

[MonoPInvokeCallbackAttribute(typeof(LuaCSFunction))]
static public int foo(IntPtr l) {
    MyType self=(MyType)LuaObject.checkSelf(l);
    int bytesLen;
    IntPtr ptr = LuaDLL.lua_tolstring(l, 2, out bytesLen);
    byte[] bytes = new byte[bytesLen];
    for (int i = 0; i < bytesLen; ++i) {
        bytes[i] = (byte)Marshal.ReadByte(ptr, i);
    }
    self.foo(bytes);
}

If the engine can include this kind of conversion code, it will be better.

I think maybe I should fork slua and send some pull request :)

Current Version (.81) Produces Runtime Errors on Unity 5.0.2

Pretty much every example scene (circle, Delegate) produces either a runtime exception or Lua exception when run in Unity 5.0.2. Havent tested in Unity 4, but I imagine it would be the same.

Subscribe to C# Events in Lua

Thank you for your response to my other posts.

I was wondering if SLua supported subscribing to C# events? I can see why this might be difficult/impossible, but wanted to see if you had any solution?

Thanks

3rdDLL and custom export same Type lead to compile error

Nested Classes

Hi,
We were experimenting with using Nested classes and noticed that Slua does not seem to be compatible. Specifically, when we use the [CustomLuaClass] attribute on a nested class, these classes are appended to their container class with a "+", which causes compilation to fail.

Generate code under System namespace

Hi,

In the OnAddCustomClass I added the following:
list.Add(typeof(System.IO.Directory));

But the code generated has a lot of compilation errors. The same happens to a lot of other classes under System as well.

A workaround is to write some custom wrapper class calling into those system classes, but a working native support would awesome.

Stolen code

I wrote uLua, and you use stolen code. I have proof, and if you don't remove this project I will use legal means to have it removed.

When you purchased uLua it did not give permission for you to reuse code owned by me and PNG for your own releases. This is your only warning.

iOS ARM64 luajit (lua5.1)下LuaDLL.lua_pushinteger的bug

(32位平台不受影响；lua5.3不受影响)

unity3d的c#重现代码:

l.luaState.doString("print(a)"); // expect: nil, result: nil
LuaDLL.lua_pushinteger(l.luaState.L, -1);
LuaDLL.lua_setglobal(l.luaState.L, "a");
l.luaState.doString("print(a)"); // expect: -1, result: 4294967295

LuaDLL.lua_getglobal(l.luaState.L, "a");
Debug.Log(LuaDLL.lua_tonumber(l.luaState.L, -1)); // expect: -1, reulst: 4294967295
LuaDLL.lua_pop(l.luaState.L, 1);

原因:

因为在arm64下，编译的lua库ptrdiff_t实际等于：int64_t，(PInvokeFunc)lua_pushinteger强转后，函数定义不一致，导致 lua_pushinteger接受第二个参数错误。

临时解决方案

修改LuaDLL.cs文件中：
public static extern void lua_pushinteger(IntPtr luaState, int i);
为
public static extern void lua_pushinteger(IntPtr luaState, Int64 i);

分析参考

lua5.1文档中：

typedef ptrdiff_t lua_Integer;
void lua_pushinteger (lua_State *L, lua_Integer n);

LuaDLL.cs中对于lua5.1:

public static extern void lua_pushinteger(IntPtr luaState, int i);

转换为il2cpp:

// System.Void LuaInterface.LuaDLL::lua_pushinteger(System.IntPtr,System.Int32)
extern "C" {void CDECL lua_pushinteger(intptr_t, int32_t);}
extern "C" void LuaDLL_lua_pushinteger_m4400 (Object_t * __this /* static, unused */, IntPtr_t ___luaState, int32_t ___i, const MethodInfo* method)
{
    typedef void (CDECL *PInvokeFunc) (intptr_t, int32_t);
    static PInvokeFunc _il2cpp_pinvoke_func;
    if (!_il2cpp_pinvoke_func)
    {
        _il2cpp_pinvoke_func = (PInvokeFunc)lua_pushinteger;

        if (_il2cpp_pinvoke_func == NULL)
        {
            il2cpp_codegen_raise_exception((Il2CppCodeGenException*)il2cpp_codegen_get_not_supported_exception("Unable to find method for p/invoke: 'lua_pushinteger'"));
        }
    }

    // Marshaling of parameter '___luaState' to native representation

    // Marshaling of parameter '___i' to native representation

    // Native function invocation
    _il2cpp_pinvoke_func(reinterpret_cast<intptr_t>((___luaState).___m_value_0), ___i);

    // Marshaling cleanup of parameter '___luaState' native representation

    // Marshaling cleanup of parameter '___i' native representation

}

c语言重现例子：

#include <stdio.h>
#include <stdint.h>
void test1(int64_t i)
{
    printf("%lld\n", i); // result: 4294967295
}

int main()
{
    typedef void (*PInvokeFunc) (int32_t);

    static PInvokeFunc _il2cpp_pinvoke_func;
    if (!_il2cpp_pinvoke_func)
    {
        _il2cpp_pinvoke_func = (PInvokeFunc)test1;
    }

    int32_t i = -1;
    _il2cpp_pinvoke_func(i);
    return 0;
}

Stack is left inflated by missing pop in LuaObject_basetype.cs checkType(IntPtr l, int p, out Type t)

I was encountering an issue where the stack size (top) was increased after a binding called checkType. This confused a checkParams call later on because checkParams thought it had more inputs than it actually had (because top was increased).

Within the LuaTypes.LUA_TTABLE switch case, if the __type rawget pushes a nil value on to the stack, then the else case immediately does another rawget for __fullname without ever popping the nil value from __type off the stack. Now, both the values for __type and __fullname are on the stack, and the pop at the end of the else case only pops the __fullname value, but does not pop the nil value from __type.

I believe a fix is to add another pop at the beginning of the else case, right before pushing the __fullname string.

Error in checkType() when managed Vector3[] value is passed from luastate to managed function

https://github.com/pangweiwei/slua/blob/master/Assets/Slua/Script/LuaObject_overload.cs#L56-L68

I attempt to pass Managed Vector3[] object as parameter from luastate to c sharp function.
but, an error is occurred.

following example code.

in C#
[SLua.StaticExport] static public void Path(Transform target, Vector3[] path, float duration, string pathType, string ease, bool orientToPath = true) {
luascript
Path(params.root.transform, GetPath(params), params.event:GetValue('m_movingTime'), 'CatmullRom', 'Linear', params.event:GetValue('m_orientToPath'))

return type of GetPath is Managed Vector3[] object.

my workaround solution : https://gist.github.com/Salada/7c82fab23cf4d6e8cbf1

I wish you resolve this problem in your way, if you want.

thanks.

why can't some UnityEngine's struct without explicit constructor construct in Lua

like Physics.RaycastHit

I should've use local a = Physics.RaycastHit(), it's a struct, without explicit constructor though, it's allowed to construct obviously in C#.
but the binding code is like:

static public int constructor(IntPtr l) {
        LuaDLL.luaL_error(l,"New object failed.");
        return 0;
    }

It doesn't make sense

windows 64bit Lua 5.3, unity crash when using table after calling a coroutine.

Build lua5.3 64bit tested in unity5, unity4.6.4(32bit), add macro LUA_5_3 in script,
modify last line of "resumefunc" in LuaState.cs from "return unpack(ret)" to "return table.unpack(ret)".
Then test main.unity, the editor will crash with error:
---------------mono.dll caused an Access Violation (0xc0000005)
---------------in module mono.dll at 0033:ed8d331a.

I test the code, and found that the crash caused by visiting a table after using coroutine, the short example to produce the issue:
local c = coroutine.create(function()
Yield(WaitForSeconds(2)) --<--------------- works fine if this line is commented
end)
coroutine.resume(c) --<--------------- works fine if this line is commented
local x=UnityEngine.GameObject("OoOo")
print(x) --<---------------- you will get a crash

Debug in mono, found:
internal static int print(IntPtr L)
{
int n = LuaDLL.lua_gettop(L); --<---------------------------- crashed after calling this
...

BTW, I build the slua.dll with vc2013, Is there anything wrong if i setup a project and build dll with vc2013 ?
Did not find the reason yet...

LuaState close does not actually close (as described by its own comments), plus another bug when re-enabling closing

I've been intentionally closing my LuaState objects for awhile, believing that was closing the LuaVMs. I was very confused by why my Unity editor sometimes would fail to allocate new pointers in my native extensions. I eventually discovered the comments in LuaState:

                // be careful, if you close lua vm, make sure you don't use lua state again,
                // comment this line as default for avoid unexpected crash.
                // LuaDLL.lua_close(L);
                // L = IntPtr.Zero;

This was very surprising to me. While it's nice that the comments are there describing why you commented those lines out, there's nothing leading users of Slua to those comments. Either way, not closing the lua VM because of an "unexpected crash" is simply hiding other issue with the user's code if those crashes occur. Indeed, once I added the lua_close back, I did not start to experience other issues, but those issues were real and needed to be fixed.

In fact, one of the issues I discovered by re-adding lua_close was a rare (but very annoying) bug with Slua. In ObjectCache.del, the lua state is correctly removed from the multiState map, BUT oldl and oldoc are not cleared out (set to IntPtr.Zero / null). I believe this leads to a rare condition, where if a lua state is destroyed, and then another is created, the second lua state may have the exact same pointer address as the previous. Because it has the same address as before, the cache incorrectly pulls up the dead cache from oldoc.

Similarly, when a LuaState is closed, it should be removed from LuaState.statemap, and LuaState.oldptr and LuaState.oldstate should be cleared out. This doesn't appear to be happening on master, either.
