Graphics / Re: How would you do player animations?

« on: January 06, 2014, 06:57:49 am »

I looked at the way Unity does things, and it looks like they have an encapsulation of Animation, and then you can add different animations based on the "state" you're in for walking forwards and backwards and any other actions. Thanks for helping!

Well, right now my entities all have their own "animations" stored, but they're all individual objects, so I have like 16 Animation objects because I need one for each direction/action. The code is messy, and I'm just wondering if anyone has completed a game or has come close that could show me how they did it.

Graphics / How would you do player animations?

« on: January 06, 2014, 04:54:49 am »

I make games in C++ and SFML with OpenGL from GLEW. I have SFML for input and windows, and all of my rendering is done from normal OpenGL. Currently, when I use animations, I have an Animation class that holds all of the frames for each animation, and how long each frame should be displayed (two int std::vectors, one for ticks and one for frames), but the problem is when I have to add new animations to my entities or dealing with multiple animations at once.

During initialization, I create animations for my characters, (which I want to change to data-driven, but not a huge priority right now) and I store the animation to my current character and any enemies that start out. The problem is, I have like 12 different animations that have to be stored(in each direction: walk, idle, run, hurt, attack), and if I want to spawn new entities, I have to either store a copy of each animation for each entity type (which I want to eventually be randomly different), or I have to load them each time. It just seems.. difficult to keep track of so many. All the animation tutorials I find online are the very basics about changing your texture coordinates for the next frame, but nothing too in-depth.

for future reference, make sure you either post where we can find dependencies, or include them in the download file. It's a real turn-off when you find out you need to go out of your way to play something.

well, I rebuilt using the source from the 2.1 downloads page (instead of github), and now my linker errors have changed, and instead of 42 errors, I have 41. They all have to do with sfml-window-s.lib, and the last ones all had to do with glew..

Did this change happen before or after the 2.1 release? Could I just bypass it by remaking the actual 2.1 release instead of from github?

so, I downloaded SFML 2.1 to build with CMake so I can change the static libraries to not use the standard libraries, but when I do, I get 42 linker errors. I followed the tutorial as closely as possible, but I either missed something, or I'm derping somewhere.

I'm assuming I'm missing something small, but I have SFML_STATIC, I'm using /MT, I built SFML Statically (I only have the '-s.lib's), and I built with the SFML_USE_STD_LIBS flag set to false so I can link statically, but apparently I can't. Does anything jump out at you? I also use glew from their website so I can use Vertex Buffer Objects for rendering with OpenGL.

Nevermind. Turns out I forgot to remove the window.display() function from the main thread loop and it was crashing in a different area. That was an awkward bug combination. My apologies.

I'm using a multi-threaded program to use one for rendering and the other for things with the CPU.. but after I create the second thread and start the context in it for the window, I'm unable to do anything with the TCP socket without it crashing. Is that it, or am I doing something wrong?

Graphics / [SOLVED]Vertex Buffer Object error

« on: February 18, 2013, 12:06:44 am »

so.. I have NO idea why this is throwing an exception, but it's crashing my game whenever I call glDrawArrays. I set everything up correctly, and I've even copied-pasted code from tutorials that show people how to use VBOs, and it goes up to the glDrawArrays, and then crashes. I'm using sf::Renderwindow, and I get the error 0xC0000005: Access violation reading location 0x00000000.

Not for the RC code base, since that's already quite outdated, but I maintain Unofficial Nightly Builds.
Note: If you talk about SFML 2 RC you're referring to the code base at the time the release candidate got published.

I downloaded it and tried using the STATIC_STD libs you built, and the errors with the Runtime went away. I don't quite know why mine weren't building. But, thanks for the builds!

General / Any idea on why I can't use /MT?

« on: February 08, 2013, 04:19:41 am »

I built SFML 2.0 RC with CMake with a tutorial I found online, and I know it works, because I've used it before (with /MD setting), and it worked fine. I want to use the /MT flag with SFML, and I found out through the forums I need to rebuild it, so I installed CMake and did everything I had to with VS2012 command prompt, and it built fine. I made sure I used the "SFML_USE_STATIC_STD_LIBS=TRUE", but it still gives me the errors in studio when I try to compile it with link errors like
 

sfml-window-s.lib(Window.cpp.obj) : error LNK2038: mismatch detected for 'RuntimeLibrary': value 'MD_DynamicRelease' doesn't match value 'MT_StaticRelease' in Source.obj

I'm so frustrated, because I've spent hours trying to fix this, and I have gotten no progress at all. Can you tell me what I need to fix to get this to work?
I'm using the settings -G "NMake Makefiles" -D CMAKE_BUILD_TYPE=Release -D BUILD_SHARED_LIBS=FALSE -D SFML_USE_STATIC_STD_LIBS=TRUE
Would someone by any chance already have pre-built sfml 2.0 RC with these specs?

I'm not too worried about it, but its definitely an inconvenience because I have no clue how much CPU my loop takes when my rendering is taking all of it.
