      GameDev.net and CRC Press have teamed up to bring a free ebook of content curated from top titles published by CRC Press. The freebook, Practices of Game Design & Indie Game Marketing, includes chapters from The Art of Game Design: A Book of Lenses, A Practical Guide to Indie Game Marketing, and An Architectural Approach to Level Design. The GameDev.net FreeBook is relevant to game designers, developers, and those interested in learning more about the challenges in game development. We know game development can be a tough discipline and business, so we picked several chapters from CRC Press titles that we thought would be of interest to you, the GameDev.net audience, in your journey to design, develop, and market your next game. The free ebook is available through CRC Press by clicking here. The Curated Books The Art of Game Design: A Book of Lenses, Second Edition, by Jesse Schell Presents 100+ sets of questions, or different lenses, for viewing a game’s design, encompassing diverse fields such as psychology, architecture, music, film, software engineering, theme park design, mathematics, anthropology, and more. Written by one of the world's top game designers, this book describes the deepest and most fundamental principles of game design, demonstrating how tactics used in board, card, and athletic games also work in video games. It provides practical instruction on creating world-class games that will be played again and again. View it here. A Practical Guide to Indie Game Marketing, by Joel Dreskin Marketing is an essential but too frequently overlooked or minimized component of the release plan for indie games. A Practical Guide to Indie Game Marketing provides you with the tools needed to build visibility and sell your indie games. With special focus on those developers with small budgets and limited staff and resources, this book is packed with tangible recommendations and techniques that you can put to use immediately. As a seasoned professional of the indie game arena, author Joel Dreskin gives you insight into practical, real-world experiences of marketing numerous successful games and also provides stories of the failures. View it here. An Architectural Approach to Level Design This is one of the first books to integrate architectural and spatial design theory with the field of level design. The book presents architectural techniques and theories for level designers to use in their own work. It connects architecture and level design in different ways that address the practical elements of how designers construct space and the experiential elements of how and why humans interact with this space. Throughout the text, readers learn skills for spatial layout, evoking emotion through gamespaces, and creating better levels through architectural theory. View it here.

  1. Thanks Andreas - I thought it might be something like the vptr - but assumed the lack any inheritance would nuke it :) I will try it later on today - I really hope it works - because having that anonymity saves me a fair bit of typing and fits with my reckless R&D code style :)
  2. Hi There   I'm trying to pass arrays from angelscript to C - and having a few problems   The problems being it doesn't work at all - doesn't fill the vec array - and probably will eventually crash - I can't really tell what is going - because the C code is compiled at run time and my shabby system has no really debugging at the moment.   here's my C code:   typedef struct { int maxElements; int numElements; unsigned char  data[1]; }  SArrayBuffer; typedef struct { int       refCount; _Bool      gcFlag; void*     objType; SArrayBuffer*     buffer; int       elementSize; int       subTypeId; } ASarray; void Init(void) { Debug("TCC init called"); //asRegisterGlobalFunction("float TestFunk(float)",TestFunk); //asRegisterGlobalFunction("vec3 vectest(vec3)",vectest); //asRegisterGlobalFunction("vec3 vecpointer(const vec3 &in)",vecpointer); asRegisterGlobalFunction("void vecfill(vec3[]@,int)",vecfill); } void vecfill(ASarray *a,int l) { vec3* v=(vec3*)a->buffer->data; for (int a=0;a<l;a++) { v[a].x=counter++; v[a].y=counter++; v[a].z=counter++; } }   here's my angelscript code array<vec3> TestArray(50); vecfill(TestArray,2); I am doing it this way because 1) I want to be able to pass arrays anonymously without having to define a specific class or struct 2) I'm using TCC so the C code is compile at runtime - it's actually called from angelscript: ExecuteTCC("./NewDir2/Test.c","Init"); I realise this is probably as dodgy as hell - but it's  not a commercial thing, pure R&D - so I just hope it is possible.     thanks!
  3. I had a quick look at the exe - coz I'm so nosey and enjoy mystery .exe's it's a legit PE, I didn't check for any nasties but it's:   "Allegro Game Creator"   uses: OpenAL wxWidgets OpenGL some GCC stuff and a few more     probably doesn't load because it uses a few .dlls   libgcc_s_dw2-1.dll libgcj-13.dll   and it does have that function above in there:   int __thiscall sub_401838(void *this, int a2) {   int v2;

  4. Hi Andreas   >>However, BCB6 is more than 10 years old already. Any particular reason why you're still using it?   I know :) - I use BCB 6.00 for my really fast R&D work - the compiler is uber fast and the VCL component architecture is wicked and the portable install size is 30mb - for me it's the fastest way to do disposable native c++ R&D work. Quite tragically I have to totally ditch it soon tho - since the debugger doesn't work in x64 :(    Shabby
  5. Update to my problem   Investigating the problem further - it seems it's related to stl stringstream - it gets stuck in some sort of deallocation    so I commented out anything to do with stringstream - which is a lot of the stdstring extension - and I get no hang - yaay!! but I also no fully working string - booo!!   I really don't understand the under the hood stl code - it's all voodoo to me, looks like the stream code is used for int/float to string conversion so I can easily work around it.   I'm guessing that it's a Borland compiler/STL port issue - I actually tested this and is completely a STL port issue (with a standalone exe - no angelscript) - nothing to do with angelscript :)   and easy fix for any other crazy folk using BCB 6 - is to enable    # define _STLP_DEBUG_UNINITIALIZED 1   in STL's STL_USER_CONFIG.h    no more windows hang - yaaay :)
  6. Hi Andreas   Yes I tried that eariler, I changed the AS_USE_STRINGPOOL define, no joy tho :(   btw - thx for your awesome work Angelscript, my fav scripting lang by far!       Shabby
  7. Hi All I've got a problem with the Latest version of angelscript and borlands BCB 6.00 - I got it to compile (there were a few compile issues - but very easily fixed). It all worked fine - Building angelscript code exectuing e.t.c. - The problem happens when using the STDSTRING extension, using strings in script works fine and it compiles and runs - the problem is that my EXE hangs when exiting back to windows - I've tried to track down the issue - but no joy yet - anybody got any similar issues?   I've tried the following scenarios:   RegisterScriptArray(Angel,true); RegisterStdString(Angel);   Exe hangs when exiting back to window - even if my script code has no string usage   RegisterScriptArray(Angel,true); //RegisterStdString(Angel);   Exe is fine and exits back to windows properly   //RegisterScriptArray(Angel,true); RegisterStdString(Angel);   Exe hangs when exiting back to window - even if my script code has no string usage   I'm thinking it's some kind of STL Issue - but who knows?     here's the call stack from the hang ******************************** 005599F2 _STL::__node_alloc<1, 0>::_M_deallocate 00532B94 _STL::__node_alloc<1, 0>::_M_deallocate 004ABC13 TForm2::~TForm2 004AD53B TForm2::~TForm2 00534D54 _STL::__node_alloc<1, 0>::_M_deallocate 0053409C _STL::__node_alloc<1, 0>::_M_deallocate 00533FFF _STL::__node_alloc<1, 0>::_M_deallocate 005196C3 __init_exit_proc 00519712 __cleanup 005189D4 _exit 005198E8 __startup ******************************* many thanks   Shabby   p.s. anybody else trying to uses BCB 6.00 you have to change any of the macros that have a ; after them, bcb wont compile class with ; and no definitions.   from: protected: DECLARECRITICALSECTION(cs); to: protected: DECLARECRITICALSECTION(cs)   and some of the object pointers have to be explicitly cast before the compile will swallow them (forget which ones - easy fix tho).
  8. Hey Andreas    Yeah I thought there would be some sort of declaration I was missing, I just couldn't find it in the doc.   Just got my vec2,vec3 and vec4 classes 100% matched to GLSL and my own native classes - let the uber quick prototyping begin :)   Just wanted to say - thanks for all your awesome work on Angelscript - it's like a dream come true - soo soo soo easy to bind to native c++ it's the script system I've been after for ages - but only just found it now :)     Shabby
  9. Heh - in answer to my own question - and a few posts down   gScriptEngine->SetEngineProperty(asEP_ALLOW_UNSAFE_REFERENCES, true);   allows the ref to work - sweet!
  10. Hi All   I've just discovered angelscript and totally love it - having used lua,squirrel e.t.c. it's just awesome - everything I've need in a script lang - typed fast and easy to convert to native code.   I've currently got a problem with my vec3 class - I'm using global functions instead of member functions so I can directly match GLSL - this is so I can easily convert code from native c++ to GLSL and to script if needed.   I'm trying to register a global func:     r = gScriptEngine->RegisterGlobalFunction("vec3 normalize( vec3 &v1)", asFUNCTION(normalize), asCALL_CDECL);     but I get error -10 and "Failed in call to function 'RegisterGlobalFunction' with 'vec3 normalize( vec3 &v1)' (Code: -10)"   and I just can't figure out the issue, apologies in advance if it's silly problem - I've looked at all the various vector3 classes out there and search the net for answers - but no joy yet :(   thanks   Shabby
  11. Hey That's cool I actually did that on my first pass, a very similar mechanism of just a Func pointer and some timing, my only issue with that is, I have to write multiple callbacks. I'm using frames because it's guaranteed to run at 60fps - else I would be using parametric seconds as the timer. If I was working with a big team - I would engineer it so it's super awesome and all that, My main thing is that I'm designing this game and writing it at the same time, and I'm finding that having to switch from engineer to design whilst I'm coding really kills the creativity, hence I was looking for a super slick way of doing it. It sounds bonkers that - having to write a small function could do that - but that really does happen with me! void BigEyes(u32 FrameTime) { switch (FrameTime) { case 0: TweakMorphFromFile("EyesBig.txt",0.2); break; case 50:TweakMorphFromFile("EyesMassive.txt",0.2);break; case 100:TweakMorphFromFile("EyesNormal.txt",0.2);break; } } void BlinkEyes(u32 FrameTime) { switch (FrameTime) { case 0: TweakMorphFromFile("EyesBlink.txt",0.6); break; case 10:TweakMorphFromFile("EyesNormal.txt",0.4);break; } } void MainLoop() { if (rr<0.01 && rr>=0.005) AddSequence(BlinkEyes,0,11); if (rr<0.005) AddSequencer(BigEyes,0,101); UpdateSequences();}
  12. That sounds interesting, I envisage that to work something like this: (assuming the string pool compare works) void TriggerSys(char* TriggerName,u32 FrameTime) { switch (TriggerName) { case "BigEyes" : { switch (FrameTime) { case 0: MorphToBigEyes(0.1); break case 40: MorphToSmallEyes(0.1); break case 80: MorphToNormalEyes(0.1); break } break; } case "BoomSound": { PlayWav("Boom.wav"); break; } } } void TriggerHandler() {...} MainLoop() { if (thisthing) { AddTrigger("BigEyes",0,81); // Trigger BigEyes in o frames time for 81 frames duration AddTrigger("BoomSound",100,1); // Trigger BoomSound in 100 frames time for 1 frame } TriggerHandler(); } is that what your talking about?
  13. HI I'm trying to come up with a way to sequence code easily and without using a million classes. I want to be able to execute code x frames in the future for y frame duration - something like this: if (HitSomething) { Seq(10,20,PlaySound,"CrashHit.wav"); // Call fun Playsound("CrashHit.wav") in 10 frames time for 20 frames Seq(10,50,StarFlare,10,20,1.5,4); // Call func StarFlare(10,20,1.5,5) in 10 frames time for 50 frames } This is great because it can handle any function, and the code is localised. I can do this - but it's alot of work to get the Variadic stuff working across different platform - requires some hardcore asm to calc the Param stack Size and setup the epilog code e.t.c. wondering if there are any neat tricks to get something similar.
