Digital Spaghetti posted:A little update on my game development adventure. Welcome to the cult  We are all Guido's children Pygame is an awesome little library, and its drat easy to bully around. If you want a really basic 3D engine to play around with Panda3D is dead easy. Its very basic, and I wouldn't expect to be able to create anything remotely professional, but its a good little learning tool and its dead easy. Its a shame it doesn't seem so maintained however.

Been playing with PyODE, the python wrappers for the ODE physics engine. Plays real nice with PyGame. http://pyode.sourceforge.net/tutorials/tutorial2.html Added a bunch of nodes and motors and poo poo to the tutorial, and just watch it flail around. Neat as hell. Putting extreme values into things makes some pretty loopy 'physics'.

Re NeHe, I taught myself GL based on his stuff, and it was fine. Although in fairness I already had a pretty spot on knowledge of trig and matrix. Some of it is garbage however, and I'm fairly convinced his explanation of portalling was plain wrong, although the code was roughly right.

Cinema4D is pretty loving easy to use, but its bit of a wallet hit. The import/export stuff gets a bit loving wierd though. Just model it up, hit "bake object" and select single texture and normal maps and your good as gold. The Bodypaint texture/uv paint stuff is loving awesome. Still getting my head around the animation subsystem though. Theres a few mild incompatibilities that are enough to be more than a little agravating. The thing with 3D though, is you need a *lot* of it. e: Also, heres some free money for anyone that wants to tackle it: Theres a lot of money to be made in decent middleware I suspect. A good locomotion system that can actually model walking/stumbling and generally animating a skeleton in a sane way without requiring baked in mocap animations would sell to indy devs like wildfire. Likewise with a good face talking + emotional face mesh deformation system. If you can get it to work with models from evolver, indy devs will loving love the poo poo out of you, especially if you have a relatively cheap version for Unity. Hell, add in A* pathing, and maybe even a decent behavior tree system, and you basically have a drop in AI system for indy 3D games.

mewse posted:i liked the vid where they're like "our walking man can't fall over!!!" and they hit him with like a billion impacts that would knock a real person on their rear end while robot man's legs float merrily along defying gravity I was looking at some papers last night with my mathematician flatmate, and he summarized the problem well. "The papers on the topic combine biomechanics, computer science, physics, and a hard math problem with no guarantees your algorithm will finish if you want to model it right (I think he was refering to finding optimum IK solutions or something?). Its ugly as hell! To the best i can figure it, if you wanted to do a convincing legs simulation, you'd do something like using your front foot, shift your center of gravity to some value of something past your leading foot, effectively sending you off balance forward then you pick a position in front of you to put your back foot, and quickly swing your leg forward to land there. The positon should provide enough momentum that your center of balance flips forward until its back out of balance but with the axes reversed. repeat. So its basically controlled falling and managing the momentum of the center of balance position as to not fall over hilariously in a qwop type manner. Harder said than done however, since your solving multiple problems, that fight each other in a dynamic sytem , some involving IK equasions that might not have a clean solution anyway. (afak There are P-time IK algorithms, but aparently they are not optimal.) All of which has to be done in a manner that does not resemble some sort of hilarious spaz legged chicken monster (constraints!) MEANWHILE the top half of your body is doing all sorts of top-half poo poo like flapping around being a video-game gangster. Then just to gently caress it all up, theres hills, turning ,getting thumped and having to adjust feet position to try and counter it, jumping, etc etc etc. Its not very easy to make it look convincing, but I'd argue one could make a good sum of cash undercutting the gently caress out of the big-name solutions, if it looked good, because animating skeletons from mocap is a giant loving pain in the arse. duck monster fucked around with this message at 12:32 on Jan 5, 2012 |

Gordon Cole posted:I'm sure it makes perfect sense if you know the language, I've just never seen anything like it before. Forth is like if someone invented the most simplest , powerful and logically coherent verbal language ever, but it was so different to the way normal humans spoke that if you heard it, it sounded like TV white noise. Forth in a sentence: Everything is stacks, you put things on a stack then you do something to the stack and put the result on the stack. Thats it, forth explained. I should also add, that its ridiculously meta-programming-ish. Out of the box it doesn't even understand variables, you need to teach it the concept of variables, usually with a line of code. But then you can add all sorts of constructs to it like Object oritentation and it becomes more and more powerful and expressive as it goes on. And you name it, you can implement the fucker in forth.Te end result is that its the ultimate toaster-coding language, it can be assembly-language close to the metal, but you can implement some serioualy high leve l constructs in it. I remember in the 90s being utterly mystified why Unix was implemented in C rather than forth. I guess lisp guys wondered the same (although unlike lisp, forth can be extremely fast, not that it really matters with modern lisp compiler design, but it sure did used to matter!) The details are a bit more complex, but like lisp its all about taking a loving simple concept and using that concept to expand into something rich and powerful. Also Forth is one of the simplest languages on the planet to write a compiler for, because its such an inherently simple language. My first forth compiler was about 10 pages of qbasic, that compiled it to Z80 code, sometime in the 90s. Someone who is not me should do a 'Lets teach ourselves forth" thread. Its a language that when the penny drops as to how to "think" in forth, it'll cause you to look at the way you think about code in a totally new way, and your hair will blow back just a little bit. "Its like Everything is reverse polish now, like out there is the true world, and in here is the dream". Forth won't let you gently caress a giant blue chick though. duck monster fucked around with this message at 12:20 on Jan 9, 2012 |

loving unity. I've been coding away at an OcTree boxely voxely type thing , mainly because it seems like an interesting thing to do, and I decided to use Boo because it looks a bit like python, and python is cool yeah. gently caress! Boo is Mostly like python except it really loving isn't, its sort of C# with crazy rear end syntactic sugar and duck typing usually but not always. The probelem is, boo is just poorly documented. The boo language has very poor documentation, and theres even less about how to use it in Unity, although I've pretty much been able to infer that part from reading the C#. I spent half a day banging my head on the wall trying to figure out how to pass arrays to a loving function. Something so god drat basic , but yet its not documented anywhere. Turns out its just def blah (something as (type)): right cool. Next cab off the rank. Appending to an array. *digs through manual* Oh  This loving thing.

Its not well documented, but little in unity is!. But you definately can. My first one just created instances of cubes. Obviously thats not the final solution, so from there I've been building a big mesh out of it. If I wanted to do something serious with voxels, unity would not be my first choice (although I guess you could probably do something fun using the low level GL interface in unity, but..... meh. I'd like to avoid dotnet/mono exposure where possible).

God help us all if Autodesk ever manages to aquire something like the UDK or whatever, because it'd handball autodesk way too much industry control.

Boo is potentially a really neat language, but its undocumented nature makes it an exercise in fruturation. Your probably better off taking the plunge and working out C#.

So I decided to do a double whammy and re-teach myself C++ (I've gotten really loving rusty!) and learn the cocos2dx framework while I'm at it. So the logical choice is to use the new 3.0 branch. Holy poo poo what a learning curve. The C++ i can cope with, to a degree. I used to do C++ a couple of decades ago and slowly the old info is re-revealing itself, although the language has changed a bit now (Did you know C++ apparently has gained an iiterator version of for loops? Neat) seemingly for the better. The hard part is they've changed the loving API beyond recognition from 2.0 meaning *ALL* the tutorials don't work, and all those blogposts dont work. And its not just that they've renamed most of the functions (Apparently they are pulling away a bit from the ObjC by dropping the prefix pseudo-namespaces and using proper C++ namespacing. I guess thats a good thing) they are straight up changing how things work. The upside is those changes are mostly to use the standard library , which is forcing me to learn the standard library all over again. Thats also te downside.  Learning is hard when your an old man. With all that said, Cocos2dx loving owns bones.
