I want the background to be a flyover of a sauer map and the sauer logo in the corner and the loading bar at the bottom. Is this possible?

Does anyone Know? I know i would have to edit the source...

If you ask questions like that just forget about it! Don't even touch the source!! Go 10 feet away from your computer at all time!!! From all computers!!!!

To be serious for a moment (what is not so easy in this case) you may think about your question again.

I'm sure its not so hard to implement this feature for somebody who knows the source. But its not possible for somebody who don't even try to read the source.
Or did you read the source and don't make progress at some point? Then there may some help around here.

I did read through the source but i cant seem to find the part where the loding screen is generated.

Work backward.
Take what you see, and try and find that in the source.
Example: The logo image. Find where it's referenced in the source.

For a fly-by of a map, you could have a series of invisible "platform" entities all moving the same speed and direction, thus making a "box" for the player. Not sure how to do this in the loading screen, but you could edit the part of the source that determines initial game mode and map to make it sp (so the platforms will work) on your fly-by map. Or you could find a way to stop player movement, then you would only need one platform. I think you could turn on 2d-gui and I think there might be a command in CVS that makes the menu load automatically on start.

#6: Logo Image

by cubeunkown on 05/29/2008 10:14

I found out where the logo image is and changed the background colour of the loading screen to black and i moved the logo but now the lgoo has disappered:

CODE:

int x = (w-1024)/2, y = 128;
settexture("data/sauer_logo_512_256a.png");
glBegin(GL_QUADS);
glTexCoord2f(0, 1); glVertex2i(x, y);
glTexCoord2f(0, 2); glVertex2i(x+512, y);
glTexCoord2f(0, 3); glVertex2i(x+512, y+256);
glTexCoord2f(0, 4); glVertex2i(x, y+256);
glEnd();
SDL_GL_SwapBuffers();

Uh, as this got anything to do with it?

int x = (w- 1024)/2, y = 128; ? shouldint it be

int x = (w- 512)/2, y = 256; ?

It looks like you need to learn a bit more about OpenGL - there are plenty of tutorials and books out there on the web... e.g. http://www.glprogramming.com/red/

I know i would need to move the logo as all i want is a background now. I have changed the background colour to black using glClearColour(blah) but i have lost my image by moving the cords could anyone help me with this?

I concur with #8, you obviously have little to no experience with OpenGL.

Unfortunately, it would take too long to walk you through it, and many of us are too busy or preoccupied with our own stuff to do so. We're a smallish community with an even smaller amount of coders, so really, we're not equipped to handle this kind of thing.

I'd suggest http://www.gamedev.net/ for tutorials, etc. Failing that, I suppose you could pay (or bribe/barter) someone to teach you/walk you through it/write it for you.

Would it be possible to restore the old file and take its coords ?

Did you try to change coordinates only by 0.5 or 1.0 units ?

uh i changed them all to 0 thinking it would be in top left.

Right, i managed to get the cords back, and move it but the image is too stretched. and its in the middle again. here is the snippet:

int x = (w-512)/2, y = 124;
settexture("data/sauer_logo_512_256a.png");
glBegin(GL_QUADS);
glTexCoord2f(0, 0); glVertex2i(x, y);
glTexCoord2f(1, 0); glVertex2i(x+512, y);
glTexCoord2f(1, 1); glVertex2i(x+512, y+256);
glTexCoord2f(0, 1); glVertex2i(x, y+256);
glEnd();
SDL_GL_SwapBuffers();

The texture is being drawn by picking four points on the screen and putting the texture in the square formed by those points.
If you don't keep the aspect ratio (width divided by height) the same, you'll stretch the image.
To move it and keep the aspect ratio, just set the top-left point to (0,0) and the rest of the points 0+width and/org 0+height as necessary.

Note that on a computer screen, the top-left corner is (0,0) and x and y increase as you move toward the bottom-right.

Okay, here. Both these articles provide a pretty concise explanation of drawing textures..
