Creating an inventory?

[Dr_Funfrock]

Hi

We have a game called Enchantment and we need an inventory system. How would we go about this? The reason we need it is that there will be shops around our world that sell simple items (sword, shield, potion, map etc).

I have heard that a good method of doing this would be to have movie clips for each item (there will be about 10 items to start with) that have a first frame that is blank. Then when you go into a shop and purchase an item it deducts the money and then tells the inventory something like this...

on(buy) gotoAndStop(_root.inventory.sword 2)

Then when you go to your inventory it shows that you now have it.

There are several problems with this I think though.

What i really would like is if someone has made an inventory before or knows how to do one, if they could post instructions on this thread. Its a complex subject I guess!

For a quick taster of the 3D game engine so far :-

Thanks in anticipation of your help!

I would rather use an array system to hold whatever the player buys like:

Items=new Array();

for ( i=1;i<=max_tems;i++){
items['i]=""; // init the array at the begging we have nothing

}

Items could be monney or potions, but if you have design like in Diablo ( belt or stash ) you need 2 array systems.

when ever you want to display what we have like pressing a key for example. just look in the array to see what Items we have. When you want to pick an item just modify the array.

when hitTest with item();

for (i=1;i<=max_items,i++){

if ( item['i] eq ""){ item[`i]=Picked_item;picked_item="";break;}
}
if ( picked_item ne ""}{msg="You cant pick it up";}


}

so

Might as well just add:

if (picked_item ne "") {
  msg = "You cant pick it up";
} else {
  msg = "You picked up "+item['i];
}

Hmmmmm in principle that sounds better BUT (yes there is always a but my friends!) I have no idea on how to add something like that. Is there any chance you could create a .fla documenting the basics of this for me to have a look at and see how it's done. Then I can think about adding it to my game.

These are the basics of what I would like to add.

1) Money - consisting of gold pieces
2) Potion to revive your health
3) Sword, you are given this at the start
4) Shield, to protect a bit against enemies
5) Map, of the world.
6) Bombs, to blast enemies
7) Acannian Orb, the aim of the game is to get this.

Cheers for helping......me hopes!

i would also like to see how you would make an invantory array. also, would there be a way to make a graphical interface with this, and make an engine that would search for an empty space in your inventory to put things in?
I'm confusing you i know.

Well i was trying to make like a grid with a set ammount of space bricks. then each item would have a size in bricks. then an engine would search your space(or always know),for an empty place and if there was one, then the item would be placed there, else, it would be ignored(or dropped).

i haven't an idea where to start with this.

It would seem like we have stumbled upon a very complex situation but one that if created, would give our games a totally new dimension.

Lets hope we can get somewhere with this thread!

Thanks to everyone who has /who is thinking of posting.

Dr FunFrock, i am working on an inventory for my game. I have it working so far (the graphical part). If you want to check it out, look at my game:

http://www21.brinkster.com/sli/link.html

Please ingore the graphics and everything as the game is in EXTREAM beta. But if you want to see it, there it is :P To pick up one of the red bottles, stand over it and hit the \ key. The white sliver on the left side of the screen opens the (cheesy and temporary) inventory panel. You can see the bottles in there. You cant use the bottles yet, but ill have that working soon.

Oh and ignore the dumb guy chasing you, he doesnt do anything yet, just runs after you :P

Enjoy

Humm?

An advanced menu / inventory for RPG’s sounds like a fun challenge to under take!

I will put some thought in to it over the weekend; I will let you know what I come up with on Monday!

Hey guys. Here is my idea for an inventory:
Say you have 10 places for the inventory, and 10 different items. In one movie clip, you have all the items on a seperate frame, with a stop action in the beginning.

heres some code (psuedo code, youll have to try it, i dont know if it works )

in the item:
on (enterframe) {
if (this.hittest(_root.hero)) {
_root.pickedup = true;
_root.whatpicked = 1; //or the number corresponding to this item
}
}

in the hero:
on(enterframe) {
if(_root.pickedup) {
for(item=0, item<10, item++) {
if (_root.item[item] == 0) {
_root.item[item] == _root.whatpicked; //update the array
_root.inventory[item].gotoandstop(item); //update the display
break;
}
}
}
}

I hope you can understand that. If you need to check for an item, just have a loop to check the array for the corresponding number.
