Is there a reason for this to happen? Same story as my other post regarding duplicate stock scripts. In the map C&C_Hourglass.mix I have found that on LoadLevel the preset Nod_Turret_MP has a NULL WeaponClass pointer in their weapon list.

EDIT:
It appears that it concerns 2 different turrets with IDs:
1500244 and 1500245 they both have one NULL weapon in their weapon list.

EDIT #2:
The same turrets do appear to have their correct weapon aswell:
Weapon_Turret_Cannon

I assume its for like in single player when you don't have any guns. They probably just leave the option to switch to the null weapon there so they don't have to add some hacky way to add a null weapon for empty hands/no weapon if no weapon gets selected. Or maybe your just seeing the end pointer of the list?

Then why is it called Nod_Turret_MP?
MP = Multiplayer.
Also you could just do Commands->Select_Weapon(obj, NULL); whichs deselects your weapon even if you have one. So there must be some logic for that.

EDIT:
Also there's a function called Deselect in WeaponBagClass.

And those functions might just switch to the NULL weapon is all I'm saying.

Either that or your just seeing the end of the list IE:
Weapon1->next = Weapon2
Weapon2->next = NULL

Yeah it could be indeed for deselecting but It's not the end of the list. I'm using a for loop starting with index 0 and going until WeaponBagClass::Get_Count(). Then every iteration I use WeaponBagClass::Peek_Weapon(int index) which is simply return WeaponList[ index ];

As I recall index zero of the weapon bag is always a null "no weapon" weapon... jonwil could confirm that though.

Which would make sense, far easier to have a slot for no weapon then hacking in a special "no weapon" state into all the weapon functions.

Well how I would do it is to have the WeaponIndex variable be -1. That saves 4 bytes of memory so you don't have to store the NULL pointer in the weapon list Very Happy

However, if they stored them in an array instead of a linked list -1 could cause some pretty serious issues Razz

Arrays in c++ allows you to do some really bad things lol.

Or you could just do a quick check if it's -1 before accessing the array

Well if your using an array to be fast why throw some of those gains with an index check each time ;p

Not to mention you can walk right off the end of an array in c++ as well and even start changing adjacent memory.
