Could one of you more experienced programmers shed some light on a very dim path? HOW EXACTLY DO WE SET AND RESET AND DO WHATEVER... with the new flags? Quote: LC In C, C++, or Lite-C, a flag is set at runtime by OR-ing the flags parameter with the flag (material.flags \|= TANGENT;); it is reset by AND-ing the flags parameter with the inverse flag (material.flags &= ~TANGENT;); and it is read by AND-ing the flags parameter with the flag and comparing the result with zero. LC Entities have more than 32 flags and thus need several flag parameters in lite-C. The other parameters are flags2, eflags, emask, and smask. The parameter a flag belongs to is given in its Type field. OH... that makes things much clearer... NOT!

Code: void main() { cout << "I am MrCode,"; cout << "hear me roar!"; system("PAUSE"); }

This is purely a wrong way to toggle a bit flag. All other bits of other flags would be reset if done this way. A Flag is a variable whose every bit is pointing to a flag. So you have to alter only the bit of the flag you are interested in. & and \| operators are necessary for this kind of operation. These preserve the other bits of the flag while altering the requested bits of the flag. My Specialities Limited.

If you use them, you don't need to write the slightly unhandy flag-code everywhere (it is better to read and better to understand. Code: #define set(obj,flag) obj.flags \|= (flag) #define reset(obj,flag) obj.flags &= ~(flag) #define toggle(obj,flag) obj.flags ^= (flag) #define is(obj,flag) (obj.flags & (flag)) In addition, flags can be combined like you wish, e.g. Code: set(my, VISIBLE \| TRANSLUCENT \| FAT \| LOCAL); or my.flags \|= (VISIBLE \| TRANSLUCENT \| FAT \| LOCAL); all available flags are listed in "atypes.h". This way you can define your own flags as well! But don't try to exceed the memoryspace of the variable which receives the flag(s) (a variable can store as much flags as bits it has). I hope this helps.
