save variable between different levels?

[zzzornbringer]

hi, i've been working on a little project which is inspired by the game void bastards.

 

my current problem is that i basically want to have some sort of currency that i collect throughout a level and back at my hub level i want to spend this.

 

but i don't know how to write a value into a variable that is then also saved and can be accessed after that level is complete, if that is even possible.

 

i tried having like a global script in my wad file that i access through the #include command. this works with regular scripts which is useful, but not so much for global variables, so it seems.

 

any suggestions greatly appreciated.

When you talk about global scripts, do you mean ACS? I will assume so.

 

My advice would be to use a library and properly scoped world or global variables.

thanks. the scope thing actually works. using the world scope and it works just fine.

 

i was trying to have a custom item/ammo type as band-aid, but couldn't find a way yet to read how much of that item is in my inventory.

 

ultimately a custom item type might be the better solution, because it can be displayed as ammo type on the hud. i think i've done this in the past.

 

the variable things works though, so, i'll see what i can do with that.

just an fyi, i have found a better solution for my problem. although it's certainly nice to know how to save variables between levels.

 

i have simply created a new item via decorate. i check this item via the CheckInventory function. https://zdoom.org/wiki/CheckInventory

 

for testing purposes i use these items as sort of a currency to unlock a door. if used successfully, ie with the correct amount, i take away that amount via the TakeInventory function. https://zdoom.org/wiki/TakeInventory

 

this way i don't have to count the item pickups vie global variables. both would work i guess, but this is much easier and less error prone.
