I've been looking up tutorials on the mouselook for glut and also tutorials for collision dectection. IT's all hard to understand. I feel that i need to get these two thing's out of the way before it goes full steam ahead. Just really frustrating.

The problem's with other engines, its it would take too much time to understand them. They are complex, i'm just wanting something very simple.

If anyone has code that using glulookat or glrotate and translate going.
Doing mouse look, rotate around, strafing pls let me know.

A brief history:

-Here we are!
-Oops we got hacked!

-Oops, we got hacked Embarassed
-Tutorial writer leaves
-Oops we got hacked!
-Oops, we got hacked again!
-Dammit, more hacking!
-*crickets for two years*

However, you may find this usefull.

*lol* at Vampyres nice little analysis of the 'short history of gametutorials.com'.

Banshee, instead of going through all the trouble of doing it with those basic opengl functions, most of us took the more flexible way of implementing a camera class, featuring at least:
1. Yaw, Pitch and Roll (fix yaw axis for 'freelook-style' mouse)
2. MoveRelative (relative to current orientation, perfect for strafing and moving forward/backward)

Then every frame you let that camera class spit out a ViewMatrix which you can then toss into OpenGL using glLoadMatrixF.

Yes, that is a lot of work, but no-one ever said programming a fps was easy if you don't want to use 3rd party stuff Smile

You are welcome to have a look at my code if you want, but it's Delphi, and you will have to realize that a Matrix, Quaternion AND camera class are involved. Probably just as complicated as the 3d engine stuff you peeked at before.

Just for the record: what exactly do you mean by getting "hacked"? Their stuff was free and I see no reason to hack such a site... Question

I've given up so many times.

if anywants to have look at the engine all 792 lines

Setting the camera to opengl:
Code:

PROCEDURE       TCamera.SetView(pRotate, pTranslate : Boolean);

BEGIN
  if pRotate Then Begin
    glRotatef(rx,1,0,0);
    glRotatef(ry,0,1,0);
  end;
  if pTranslate Then Begin
    glTranslatef(-PosX,-PosY,-PosZ);
  End;
END;


Rotating the camera by mouse (deltax/deltay are the difference between current and last mouse coordinates)
Code:

                   ry := ry + DeltaX / 5;
                   rx := rx + DeltaY / 5;
                   if rx >90   then rx:=rx - abs(deltaY) / 5;
                   if rx <-90  then rx:=rx + abs(deltaY) / 5;
                   if ry <0    then ry:=ry + 360;
                   if ry >360  then ry:=ry - 360;



Applying movement keys to camera variables:


Code:

  FUNCTION        TCamera.MakeLookVector(pX : single) : TVector; //Sub-Routine
  BEGIN
    Result[0] := Sin((ry+pX)*Pi/180);
    Result[1] := -Sin((rx)*Pi/180);
    Result[2] := -Cos((ry+pX)*Pi/180);
  END;

PROCEDURE       TCamera.Move(pV : Single; Speed : single);

VAR V   : TVector;

BEGIN
  V := MakeLookVector(pV); 
  PosX := PosX + V[0] * Speed;
  PosY := PosY+ V[1] * Speed;
  PosZ := PosZ + V[2] * Speed;
END;


Comments to the last code:
pV is the angle of which you want to move the camera. if pv is 0, you'll move straight forward, if its -90, you'll move left, 90=right and 180 = backwards.

It's Delphi code, but i hope, it helps you.

And don't give up Wink
Some wise men said, your first engine will never be finished. But it will surely help you to learn programming 3d applications.

I had often checked that site for updates in the past. They were always posting about being down because they were hacked, and their files got virus infections and all kinds of soap opera drama.

glutMotionFunc (mouse);

I believe this function is useless fo ar 3d shooter, i think it can't reset to the middle of screen.
I'm going to need another function to get the mouse going on this.
