Inventory... HELP!!!

[scottyboy123]

I have got everything else in my RPG working except this. How can I get a good inventory system? I need it so when you collide with an object (eg sword) a corresponding object (eg inv_sword) is added to your inventory. The inventory is in a different room, so something will probable have to be stored in an array so it can create all the objects when you go into the inventory room. I need it to create an object in the inventory room because I want to be able to click on it and make a menu pop up. (IsmAvatar, I've tried your examples but they're not quite what I need) So, can anyone help?

hm, have a persistant object called inven. If you colide with, say a sword, its adds it to inven. Depeding on how you are displaying your items, here how you can do it.

if you are doing it like this:

item[0,0]="Blah"
item[0,1]=amount
item[1,0]="Blah"
item[1,1]=amount
then when you collide, you shoud use this:

for (t=0;t<=1;t+=1){
if item[t,0]=0{
item[t,0]="Sword"
item[t,1]=1
exit;}
else
{if item[t,0]="Sword"{
item[t,1]+=1
exit;}
}

If you already have set ares for item, like this:

sword=amount
potion=amount
rune=amount

then just use the +=1 when you collde with it.


for the making an object, this is tricky!
if you are using the first method, use this:

you have to add some new arrays, so it looks like this:

item[0,0]="Blah"
item[0,1]=amount
item[0,2]=10
item[0,3]=10

item[1,0]="Blah"
item[1,1]=amount
item[1,2]=20
item[1,3]=20

the new arrays are positionings.

put this in the creation event of the inventory rooom.

for (t=0;t<=1;t+=1){
if [t,0]="Sword"{
create_instance(item[t,2],item[t,3],potion}}

then, in the potion object, make a menu when you click it. there is a good show_menu function you can use, look in the manual for more help.

Hope this helps

You Obviously haven't looked around these forums yet. I have 2 useful inventory examples on my site, along with a tutorial on loops and arrays for those of you who can't understand the inventory examples.
For my site to see the inventory examples, look in my sig

Thanks megamushroom. Do you know how I can set it so certain objects are stackable (and stack when you put them in the inventory, obviously) and some aren't?

[megamushroom]

how do you mean stack? as in add up? didnt i already say how to do that? look at isms tutorials anyway, they are good to learn off.

[IsmAvatar]

I only have 1 tutorial. The other things are Scripts and Examples

[scottyboy123]

I meant that only some items can be stacked. But don't worry, I'll just add another array (item[t,2]) and check to see if it equals true. If not, the item won't stack.
