pascal and learning 3d

[Ñuño Martínez]

Not sure if it's solved but I want to make a comment about record alignment. In the engine I wrote and used in the 2nd. PGD Challenge I didn't use records to store data that is used with OpenGL; I use vectors (ARRAY) instead. For example, to store xyz points I used something like:

CONST
  COOR_X = 0;
  COOR_Y = 1;
  COOR_Z = 2;
TYPE
  Vector3D = ARRAY [0..2] OF glFloat;

To access to each axis I use the CONST (i.e. Point[COOR_X], etc). This way I can use the "v" functions without alignment problems.

yeah it works alright now

I have a bunch of classes now, should I worry about writing destructors for them or memory will be freed autimatically when app terminates?

when it comes to classes whatever you create you must destroy. you should get heap trace up and running if you don't already. check the output file often to check mem leaks as you go along. also make sure to free up any opengl stuff in your destructors.

[laggyluk]

ok, thanks. list of leaks is so long that it doesn't fit on the screen

I built my frame work using a custom linked list design. all things are connected so I worry little about mem leaks. I worked on it for over a year before I started checking for leaks and I wasn't really surprised that I had none. so much more is possible with such a design.

Are you saying that you add all ingame classes into a single TList with which you free all of them in the end? It would be ince if you can give us more information on this approach or even show us some code examples of this.
