Can buffers have transparency? buffer1 = CreateBuffer(50,50, BUFFER_COLOR) SetBuffer(buffer1) SetColor(Vec4(1,0,0,.1)) DrawRect(0,0, 50, 50) SetBuffer(BackBuffer()) while AppTerminate()==0 doDrawImage(GetColorBuffer(buffer1), 400, 300, 50, 50) end The result is a fully red square.

I am pretty sure thats what I use. Is there an error?

I found a command SetViewport on Josh's scripted gui http://www.leadwerks.com/werkspace/files/file/27-scripted-gui/ what is the SetViewport command?

80/50 (80% of the results in 50% of the time) rule sucks. The last mile is tedious and laborious. I don't think many can have the satisfaction of knowing they got something to nice polished state. I am looking forward to seeing something that is developer friendly but has a buttery smooth asset pipeline. They tend to fight each other because of the price of abstraction. I don't think anything has gotten close to it yet. I would take great pride, and hopefully money, in accomplishing the feat.

Last week I wrote an emitter for doing easy events on objects. This week I wrote a library for handling deferred values. This is really nice for doing asynchronous programming. These 2 components are all that I really need to do async/evented programming. https://github.com/friesencr/lua_promise Promises are one of those things that are so elemental / simple they can be hard to grasp. Here is a small example of what I might use it for. function UsePotion() SelectPotion() :done(function(potion) NomNom(potion) end) end function SelectPotion() local p = Promise:new() gui = LoadPotionGui() gui:on('select_potion', function() p:resolve(gui.selected_potion) end) return p end Peace, Chris

:trollface:

is there a way to do a collision/hit test on an image that respects transparency?

Is the current working directory correct? I got that error because I was pushing all of my binaries to a separate folder. I made a bat file to launch the game ./bin/game.exe Lua uses a special variable to see where the loading paths are. http://lua-users.org/wiki/PackagePath That could give you insight.

I have abstracting a component of my gui library out for general consumption. https://github.com/friesencr/lua_emitter Fork and publish issues. OSS <3 It allows for simple event communication between objects. Check out the readme. If you want a similar experience as SendMessage but with a small decoupled object. Try emitter!!! I will be creating a promise system for lua which will allow for a really nice asynchronous story over the next week. A deferred value system is vastly superior to a system where the server takes callbacks. I find that dealing with certain problems using events and callbacks clearly states the problems and therefore simpler solutions. STATE MACHINE Y U NO EVENTS. Thanks, Chris

My current project compiles against 0x standard with MinGW.

I use the wiki alot. I have found some bugs with the api when using Lua. I would also be willing to fix problems when I find them. Being a beginner, I have found the wiki more useful than the documentation on the main site and still use it today. I also find it frustrating to find small reusable recipes for LE. The wiki might organically support this.

I have seen alot of people use cmake / scons. I have had the easiest time with projects that use premake. Which will generate projects for various architectures / compilers / ide. It also leverages lua. http://premake.sourc...ge.net/projects I am still very green with compilers and haven't bothered learning much past basic includes/linking.

Josh, you should ship with a Makefile <3 You would get at least 5 or so Chris points.

OO is kind of wierd. It uses prototypical inheritance through metatables. Classical inheritance is more obvious. Mixins an duct typing are kind of the preferred OO model in scripting languages any ways. I am a professional ruby developer. That is probably what makes me cranky. Ruby is such a joy to code in. I can't seem to get anything meaningful on one line. I miss good built in iterators. I havnt had to do much string manipulation yet but it looks really ugly. I am sitting at about 1500 lines of lua at the moment which would have been 600 lines of clear ruby. At least its not 5000 lines of c++. The things i have run into it so far. Arrays start at 1 cant return early w/o a hack really annoying to check false vs nil global variables by default no self asignment operators no ternary operators mixins + metatables break/continue is borked

I have been tempted by this for a while. http://moonscript.org/ https://github.com/leafo/moonscript It almost makes lua feel like a real language. http://snipplr.com/view/3750/awful-hack-to-perform-early-returns-in-lua/

I have tried using makedds.exe --help makedds.exe -h makedds.exe /? Are there any options to this thing? Thanks, Chris

I like the tutorial from cgmasters http://www.cgmasters.net/free-tutorials/polygon-hair-modeling/

If you are using lua and not using underscore you are probably doing it wrong. It is the only sane comprehensive set of utility functions I have found. Gives you alot of nice iterators, some OO facilities, some functional programming. If you have used other languages and miss nice things this gets you closer. http://mirven.github.com/underscore.lua/ Check it out. Hate lua less. I did have a problem with the module export. I manually aliased the '_' to Underscore require 'scripts/underscore' local _ = Underscore:new()

Kind of a different idea.

I cant wait to see what Matz is cooking up with mruby. https://github.com/mruby/mruby If you have tasted Ruby; Lua is just lame. You get used to lua not having real booleans, decent built in iterators, no built in mixin support, arrays starting a 1?? global variables by default. Lua does give you the benefit of not over thinking a problem. At least you can return multiple values from a single function... I use that all of the time Being said, I use lua for 85% of the code it seems and c++ for the rest. +1 for Lua/C++ with the hope of torching lua as soon as mruby is ready
