XLua Version 1.5

XLua has already been available as a beta extension for well over a year, but is now considered mature. It is a stable and feature-rich replacement for the previous Lua Object and Lua+ Object.

In addition to features present in the other Lua objects, XLua includes:
- Current Lua version 5.1.4 plus patches
- JIT-based VM for faster exececution
- Improved error reporting
- Support for both Lua and Lua+ calling conventions
- Support for multiple independent Lua states
- Support for global Lua states
- Support for 3rd party libraries*
- Support for multiple embedded scripts
- Syntax-highlighted script editor
- Support for manipulating selection lists
- Well documented

* Any existing Lua C Module can be recompiled for use with XLua. In addition, several 1st party C Modules were written specifically for XLua and are included with its distribution:

- MMF Interface (mmfi.dll): Directly access and manipulate other objects on the frame. Also provides access to some other MMF state.
- XLuaGL (opengl.dll): Derived from LuaGL, provides API for most of OpenGL 2.0, used in conjunction with any of the OpenGL objects.
- Array (array.dll): Provides multi-dimensional, fixed-size, non-garbage-collected storage for numerical data.

XLua Version 1.5.1

This update fixes a bug in coroutine support, which would cause MMF functions returning values to a coroutine to return nil instead. This bug was a partial regression from earlier builds.

XLua Version 1.5.2

This update fixes a minor bug where the internal editor would not appear correctly under certain circumstances.

This is a cool object. Does it work with exporters like iOS, Android, and HTML5?

[Darkhog]

Very nice object and easy to understand too. Three things though:

1. Example ext_mmfi doesn't work (nil error on line 86 in Demon AI that despite my best tries I couldn't fix)
2. Help button in the extenson's properties doesn't launch the help file (xlua.chm)
3. I feel like calling functions could be simplified. Instead of pushing parameters, why not just treat function call as "lua line"?

The latter needs a bit of explanation as I feel I wasn't clear enough. So instead of thing like this:

- Push integer parameter Global Value A
- Push string parameter Global String A
- Begin table
- Push integer parameter Global Value B
- Push integer parameter Global Value C
- Push integer parameter Global Value D
- Push string parameter Global String B
- End table
- call function "somefun"

you'd just do it like that:

- Call function "somefun("+Str$(Global Value A)+","""+Global String A+""",{"+Str$(Global Value B)+","+Str$(Global Value C)+","+Str$(Global Value D)+","""+Global String B+"""})"

1. This is due to the "mmf.newObjectClass()" function being broken in F2.5. I'm working on an updated version of the extension to correct this and a few other F2.5 specific issues, but it may be a while before I have time to finish and release it.
You can still use the mmf.newObject() function to manually a build a table containing the objects you need, however the collision detection functions will still be broken (class.testBackdrop and similar)

3. You can use the "Call with X parameters" action to achieve this; I'm unsure if you can pass a table though. If it doesn't work you might try implementing some sort of serializer in mmf and then de-serializing the table in the Lua script.

[Darkhog]

Call with X parameters, according to XLua docs is using Lua+ syntax, which is pipe (|) separated list of parameters. I want something that only has one action parameter which specifies function name and parameters in the same way you'd call the function directly from Lua code.
