General discussions / SDL vs. SFML

« on: June 11, 2011, 01:04:52 am »

is IRRLICHT some sort of wrapper for the APIs?

btw I want to teach pure OpenGL, and I posted this topic, because I want to focus on OpenGL not creating a window and messing around with it. this is one of SFML's great advantages.

Try using Qt. Setting up an openGL window is a snap.

this should answer a lot of your questions

General discussions / Platform Tutorial or Source code?

if you are merely interested in the logic required to create a game take a look at this flixel tutorial.

Of course this is on flixel which is a 2d game library so you will have to implement a more robust sprite, state management, and collisions among other things if you plan to use SFML.

If you want something simple as practice try emulating arkanoid, tetris, or something like that.

Window / Changing gamma, brightness and contrast

You should be able to make a contrast filter via shaders as well.

General / Where Did you learn OpenGL?

There are some good beginning openGL books out there.

General discussions / How works complicated 2D animations

« on: December 03, 2010, 03:38:42 pm »

another option if you're more comfortable with 3D is to animate it in 3D then render a series of orthogonal frames.

I'm not familiar with this option, could you elaborate or maybe post a link ?

do you use 3dsMax? If not it's pretty much the same for any 3d modeling program.

basically you make an animation, then render from a non-perspective viewport. In your render settings, set it to render to a sequence of images rather than a movie file.

After that you can take that sequnce of images and make a spritesheet.

Here's a classic example.

Ok That's what I was going for, it will be much easy for the animations.
I use blender, I have the version 4 of 3dsmax but it's getting old and cost way to much to buy the last one
Blender is great, and with the beta version you can really find yourself more easily of you come from 3dsmax

yeah I do need to learn blender. I worked as a 3d artist for many years so I'm trained in 3dsmax. Definitely too expensive to afford on my own though

Graphics / Most efficient way to draw a picture pixel by pixel?

« on: November 25, 2010, 02:08:20 am »

Really? awesome.

I've been meaning to check out boost. I'll take a look into it this weekend. From a quick look I see a lot of useful classes there

ok thanks, I do use them when I know I'll be resizing often but I wasn't sure if I should use them in situations like this.

Thanks for the info, I'll make sure I do that in the future

I was using the debugger, I just wasn't using the debugger enough

Turns out the error was due to a method called right after populating the array, seems the array logic was fine.

One question regarding std::vector. You would recommend using it even when I know I won't be resizing the array?

hey I've been trying to get this to work and I've been getting "std::bad_alloc at memory location" errors at runtime when populating the array.

I tried pasting sam's code that outputted the funky array since it at least compiles but I still get the same error on my end.

Here is the my original code (setting up the array in a constructor).

Code: [Select]


ScreenArray::ScreenArray( int width, int height )
{
int arrayLength = width * height;
colorArray = new sf::Uint8[arrayLength * 4];


for (int pos = 1; pos < arrayLength; pos++)
{
colorArray[(pos*4)-1] = 255;
colorArray[(pos*4)-2] = 255;
colorArray[(pos*4)-3] = 255;
colorArray[(pos*4)-4] = 255;

}

}}

I'll toss my hat in that ring. Thanks!

Thanks to SFML, I'm no longer using XNA
