[QUOTE=MADmarine;19035474]I've been toying around with Ogre3D recently, I think things are turning out

quite nice at the moment.

Here's some freaky reptile men that I modelled hanging around the backlots of a city :P

The compass you see is just a little HUD test thingy, it basically always points north. In first person

I have it so that your head can be moved independently from the body, the green footsteps show where

your body is facing.

[QUOTE=Cathbadh;19083923]Another important milestone was reached today:
Motionblur post-process effects!
[img]http://img130.imageshack.us/img130/448/screenshotmb.jpg[/img]
The method isn't as accurate as multiple interpolated passes, but the post-process effect is a lot

cheaper and pretty convincing. The clip-space velocity of every point in the scene is recorded in a

frame buffer and that is referenced by the post-process filter to smear samples from the color buffer

around.

[editline]05:29PM[/editline]

glTexImage2D only works with the currently bound texture object. The framebuffer is a different thing,

but you can have texture objects attached to the framebuffer via attachment points. The entire reason

you use a framebuffer object is so you can do render-to-texture and not have to upload the image from

system memory to the graphics card. With an FBO, you render the scene directly into one or more

textures. That's how I do my post-process effects.[/QUOTE]

[QUOTE=Maurice;19217041]Been working on something for about 30 minutes before abandoning it: ASCII Hero

Basically reads a track from a txt and makes it scroll to the left, you have to hit the O's by pressing

the right frets and strumming. Like Guitar Hero.
Those lower case o's (You can barely recognize them) are hammer-ons, and they actually work.
If you miss a note, it also keeps going, while they disappear if you hit them.

I also programmed beatlines and flexible design in; but I couldn't find something easily recognizable.

[QUOTE=NovembrDobby;19219272]I've been implementing an idea I had for a little game in XNA.

[IMG]http://i46.tinypic.com/dylseo.png[/IMG]

The player has to move into the middle of the 'structures' to remove them one by one, whilst each shape

rotates and moves and stuff. It's hard to explain without a video but I can't really make one (on my

netbook :v: (which incidentally is all I've used to develop it so far)) so I'll just upload the game so

far instead.

[url=http://www.filefront.com/15222353/Rotion.zip][img]http://i46.tinypic.com/30mpmhj.gif[/img][/url]

Keys:
-F to toggle fullscreen (might be buggy with shape positions)
-Escape to quit
-C to clean (remove) dead structures
-P to skip level if stuff breaks (there are ~17 levels in this, you'll know when it's done because they

all turn red)
-D to toggle debug

Some points and ideas:
-There are a few bugs and stuff, no sound yet.
-I'll probably make levels timed
-It wasn't originally meant to be only circles in structures, I might add more shapes but I think it

works quite well at the moment/is easy to implement.
-I tried to make the camera zoom in on the player when he/she gets inside a structure, but that got all

messy and kept breaking.
-I might make bosses (massive structures) and some kind of vague combat system, where the player can get

rid of certain shapes on certain structures by shooting them.
-I'll add bonuses like slower shape movement etc.[/QUOTE]

[QUOTE=Robber;19253335]A basic version of my sonar battle game is playable now. You can shoot pings to find your opponent, rockets to kill him and use the noise bubble to see your surroundings and possibly your opponent too. It's possible to loose or win.

[QUOTE=Robert64;19259591]Just about finished my simple puzzle game. Altered the rules and graphics a bit

along the way.

[img]http://www.robertandsherman.co.uk/images/hexpuz2.png[/img]

[b]How to Play:[/b]

* Like minesweeper, try and work out where the mines are in the grid without clicking on them.

* When you click on a tile, it will give you two pieces of information:

- The colour of the tile tells you where the nearest mine is. A green tile is touching a mine, and a

blue one is 2 tiles away from a mine.

- The number(s) on the tile tell you how many mines are near it. The green number tells you how many

mines are in the neighbouring 6 tiles, and the blue number tells you how many mines are two tiles away

from it.

- If you mouse over a tile, you will see two rings of tiles lit up around it, blue and green. This helps

you see which tiles are next to the one you moused over, and which are two tiles away.

* If you want to remember where you worked out a mine is, right click on it to flag it. While flagged,

you can't accidentally blow it up.

* If you find that you mistakenly flagged a tile, just right click on it again to de-flag it.

* If you click on a mine, you lose 50 points.

* The game ends when the mines are all located.

What happens there is that the zombie "explores" the map and therefore does not know the perfect path

immediately. It tends to hug the wall because its vision radius is 1 right now - I plan on making it 3

maybe 4, that way it won't hug the wall the entire time. You can also see that the zombie will notice a

portal and use it effectively.[/QUOTE]

[quote=nullsquared]And if a specific version of the feature you wrote crashes? How do you debug that? [/quote]
What on earth are you talking about? You start debugging the current codebase that's crashing, fix it and commit. Optionally, if you're working in a team and might need to work on some unrelated portion of the code, you might want to make a branch to work on so that you can switch to the current master with no problem.

Regarding the revision numbers vs. hashes, it's not that much of an issue - the distributed nature of Git comes with the limitation that there is no possibility to have a linear revision number. However, you don't need to enter the full hashes, but only small portions of them to find the revision you want.

Ok this time I am doing the "Drunken Ant".

Basically, you set a pixel in the middle of a grid.

Then you randomly generate a coordinate in the outer rim of said grid, the coordinates has to have a certain distance to the middle. Then you randomly let the coordinates "wander" around the grid. When they get to far away, you get a new pairir of coordinates.

When they reach any point in the grid where ne of the neigbours already IS a set pixel, they stay there and set the current pixel.
Here is the result:

[QUOTE=Eleventeen;19589758]What is a good way to turn OpenGL context width/height and some pixel offsets + pixel width/height into a quad, assuming I don't want anything off the screen due to 2D rendering?

So far, I have this non-working piece of cra

    for(unsigned int i = 0; i < artList.size(); i++)
    {
        SCursesArtOpenGL* artGL = artList[i];
        
        // Need to do some funky maths to make is so the coordinates start
        // at top-left, not the center and to make it so 1 unit is one pixel.
        
        float x = artGL->startPosX / screenWidth;
        float y = artGL->startPosY / screenHeight;
        
        float w = artGL->width / screenWidth;
        float h = artGL->height / screenHeight;
        
        glBindTexture(GL_TEXTURE_2D, artGL->texture);
        
        glBegin(GL_QUADS);
        glTexCoord2f(0.0f, 0.0f);
        glVertex3f(x, y, 0.0f);
        glTexCoord2f(1.0f, 0.0f);
        glVertex3f(x + w, y, 0.0f);
        glTexCoord2f(1.0f, 1.0f);
        glVertex3f(x + w, y + h, 0.0f);
        glTexCoord2f(0.0f, 1.0f);
        glVertex3f(x, y + h, 0.0f);
        glEnd();
    }

    struct SCursesArtOpenGL
    {
        ICursesArt* art;
        GLuint texture;
        
        int startPosX;
        int startPosY;
        
        int width;
        int height;
    };

videoLayer->attachArt(CRectI(CVector2DI(32, 32), CVector2DI(128, 256)), art);

The x,y,w,h floats all turn to 0.[/QUOTE]
I'm a little confused as to what you are asking. Are you trying to draw in opengl with units of pixel size? And the origin in one of the corners of the screen or something?
If so, then it's time to work with matrices.

//Get the current viewport dimensions
int v_dim [4];
glGetIntegerv(GL_VIEWPORT, v_dim);
//The last 2 values in v_dim hold the viewport width and height respectively

//Set up the projection matrix so that a unit in world coordinates corresponds to a pixel's dimension
glMatrixMode(GL_PROJECTION);
glLoadIdentity();
glOrtho(0,v_dim[3], 0,v_dim[4], -1, 1); //Origin in the lower-left corner of the screen
glMatrixMode(GL_MODELVIEW);
glLoadIdentity();

//Draw the scene here

I want to set it so 1 unit in OpenGL is a pixel and it starts at top-let. Sorry, I'm not good at maths.
