Yeah, that might be a better choice. Get a life, don't waste your time doing useless autistic things on your calculator. Get to know people, talk to girls, drink, smoke pot, stay intelligent, etc. Go enjoy life.

Sure. I totally agree. Please read my post ( http://ourl.ca/12034/227840 ) and tell me which tutorial is the original one, then I'll mention it.

And I did not "removed a couple of brackets and changed function names". I used the tutorial author's code to create mine. Isn't it the purpose of a tutorial ?
Also, I'm not a great coder, and I've never done a 3D engine (even if it's only a raycaster) before that. So I have to train, and that's a training. It's absolutely not a finished program, it's a trial of an engine for a possible game.

You are right, I should have given credits to the author. But what you say is a little excessive, don't you think so ?

I shouldn't have to explain you this, but it's about material (or electronic, in this case) property, not about some tutorials which you read. I'm sorry if you do not understand that, but it should be very clear and obvious. What I can see is that your code resembles very closely to that of Vandevenne, because you blatantly copied big portions of code from him. There's nothing more to it. It should also be quite obvious that a honest gesture of an educated and respectful man would be at the very least to thank him for that, not go along and pretend you made it. The purpose of a tutorial is to be a tutorial, to teach and to show (or something along those lines). It doesn't matter if you took the code from a tutorial, from a book or from a donkey's ass, all that matters is that you took vast chunks of it from someone else. That you're not a very good coder and that it's not a finished program has absolutely nothing to do with this, it doesn't give you any special privileges. I suppose it all comes down to education and good manners, two fundamental things that many people lack.

You don't actually know if Chockosta used his code or not, so I wouldn't go and accuse him, a PM asking him about this would be more appropriate. However, if this is true, then Chockosta, you should give him credit.

Alright.

Vandevenne's code:
double cameraX = 2 * x / double(w) - 1; //x-coordinate in camera space
double rayPosX = posX;
double rayPosY = posY;
double rayDirX = dirX + planeX * cameraX;
double rayDirY = dirY + planeY * cameraX;Chokosta's code:
cameraX=(x*2/w)-1
rayPosX=camera[1]
rayPosY=camera[2]
rayDirX=dirX+planeX*cameraX
rayDirY=dirY+planeY*cameraX

Vandevenne's code:
int mapX = int(rayPosX);
int mapY = int(rayPosY);
double deltaDistX = sqrt(1 + (rayDirY * rayDirY) / (rayDirX * rayDirX));
double deltaDistY = sqrt(1 + (rayDirX * rayDirX) / (rayDirY * rayDirY));Chokosta's code:
mapX=math.floor(rayPosX)
mapY=math.floor(rayPosY)
deltaDistX=racine(1+(rayDirY*rayDirY)/(rayDirX*rayDirX))
deltaDistY=racine(1+(rayDirX*rayDirX)/(rayDirY*rayDirY))

Vandevenne's code:
if (rayDirX < 0) {
        stepX = -1;
        sideDistX = (rayPosX - mapX) * deltaDistX;
} else {
        stepX = 1;
        sideDistX = (mapX + 1.0 - rayPosX) * deltaDistX;
}
if (rayDirY < 0) {
        stepY = -1;
        sideDistY = (rayPosY - mapY) * deltaDistY;
} else {
        stepY = 1;
        sideDistY = (mapY + 1.0 - rayPosY) * deltaDistY;
}Chokosta's code:
if rayDirX<0 then
stepX=-1
sideDistX=(rayPosX-mapX)*deltaDistX
else
stepX = 1;
sideDistX = (mapX+1-rayPosX)*deltaDistX
end
if rayDirY<0 then
stepY=-1;
sideDistY=(rayPosY-mapY)*deltaDistY
else
stepY=1;
sideDistY=(mapY+1-rayPosY)*deltaDistY
end

Vandevenne's code:
while (hit == 0) {
        if (sideDistX < sideDistY) {
          sideDistX += deltaDistX;
          mapX += stepX;
          side = 0;
        } else {
          sideDistY += deltaDistY;
          mapY += stepY;
          side = 1;
        }

        if (worldMap[mapX][mapY] > 0)
                hit = 1;
}Chokosta's code:
while hit==0 do
if sideDistX<sideDistY then
sideDistX=sideDistX+deltaDistX
mapX=mapX+stepX
side=0
else
sideDistY=sideDistY+deltaDistY
mapY=mapY+stepY
side=1
end

if map[mapX][mapY]>0 then
hit=1
end
end

Vandevenne's code:
if (side == 0)
      perpWallDist = fabs((mapX - rayPosX + (1 - stepX) / 2) / rayDirX);
else
      perpWallDist = fabs((mapY - rayPosY + (1 - stepY) / 2) / rayDirY);Chokosta's code:
if side==0 then
perpWallDist=math.abs((mapX-rayPosX+(1-stepX)/2)/rayDirX)
else
perpWallDist=math.abs((mapY-rayPosY+(1-stepY)/2)/rayDirY)
end

---

Vandevenne's code:
int lineHeight = abs(int(h / perpWallDist));
int drawStart = -lineHeight / 2 + h / 2;
if(drawStart < 0)
       drawStart = 0;
int drawEnd = lineHeight / 2 + h / 2;
if(drawEnd >= h)
       drawEnd = h - 1;Chokosta's code:
hauteurLigne=math.abs(math.floor(h/perpWallDist))
drawStart=math.floor(-hauteurLigne/2+h/2)
drawEnd=math.floor(hauteurLigne/2+h/2)
if drawStart<0 then
drawStart=0
end
if drawEnd>=h then
drawEnd=h-1
end

Do you want more?

Hayleia I don't know what Wolfenstein has to do with all this, you clearly did not read either the content in the link nor my last message.
