Ok well in my game I have created a class Critter, then a called
Critter* Mobs;
Mobs = new Critter[MAXMONSTERS]; // MAXMONSTERS = 5 for now

then I have where I fight some monster which the code always goes through
Mobs[I] to fight with but when I win im not sure how I remove that monster.
I tried Mobs[I].delete but gives me a error. some help would be great.

Critter* Mobs;
Mobs = new Critter[MAXMONSTERS];
// some function to attack
for(I = 0, I < MAXMONSTERS; ++I)

//then if Mobs[I].hps < 1 
cout << "u have killed the monster";
this is where I need to delete that mob

Use a standard container such as a vector rather than managing your own array.

I think I got it with a deconstructor command in class Critter called
~Critter().

so I was able to use Mobs[I].~Critter();

if this not how it should be done cause it creates leaks or what not please let me know thanks.

If you're deallocating memory in the deconstructor then there should be no memory leaks

so I was able to use Mobs[I].~Critter();

That won't remove the Critter from your array.

[morngrym]

im not sure, im just using the basic
Critter::~Critter() {}

ok it remove the critter from moving around my map. so where did it go when I called that?

or did it just cleared all the information in that Mobs[I]?

that would work too because I be needing to make another monster.

man its ARRAY.......
though dynamically allotted.........
its single element cant be OUT of SCOPE at a time.
.
so Mobs[I] wouldn't be deleted.......alone ,whenever out of scope........
for deletion inside ~Critter () { delete []Mobs; } //will delete whole Mobs..

and soln=
use shifting to bring Mobs[I] to Mobs[0]
store its addrs. in temp ptr and use Mobs++;
U r done......but now delete that using temp ptr...........
.
.
.
.
.by the way.....let me see ur game.........#interested....hope would be nice.......

Since the destructor is empty, that did nothing. You don't normally explicity call a destructor. The compiler generates a call to a destructor when an instance is deleted either via delete or when it goes out of scope.

so where did it go when I called that?

Nowhere. You didn't delete it.

or did it just cleared all the information in that Mobs[I]?

Again no. Your destructor did nothing.

well something has happened for me as when I called the destructor when I kill a Mob. I no longer see them. I have a map with 4 rooms(text based game) so when I goto room 1 and the Mobs room is the same then I see them. They can move around the rooms(works now without them getting lost), they can only move once every like 5 secs, if I attack them they cant move. I can attack them and kill them all(only 5). After I can move to all the 4 rooms and there is nothing in either.

so any ideas what happened to them?

did a little testing and it looks like the destructor has zero'd all the info in that Mob.
