Array implementation in PS

Mindcraftmax59:  so I was saying that "inventory" is used for simple things
Rjbull_:  ohh
Mindcraftmax59:  once you want to get an inventory with UI, you have to use more complex stuff
Rjbull_:  so... if I want one like minecraft
Rjbull_:  like, boxes at the bottom
Mindcraftmax59:  that one has a fixed number of slots
Mindcraftmax59:  that means that you want an array
Mindcraftmax59:  As I said, there are no native arrays in PS
Mindcraftmax59:  so we have come up with an implementation to fake them
Mindcraftmax59:  (we = I and Arisilde)
Rjbull_:  how we do that?
Mindcraftmax59:  I've used it in "Randomness, the Game", that's why I was telling you about it
Mindcraftmax59:  to have arrays, you want to use "call page" very wisely
Mindcraftmax59:  you know that we can program functions thanks to "call page"?
Rjbull_:  ohh
Rjbull_:  so I can just copy it from your level?
Mindcraftmax59:  yes and no. Because it's only an example
Mindcraftmax59:  that's why I said there was no inventory there
Mindcraftmax59:  I can explain how it works
Mindcraftmax59:  so, first, you need to know how to code a function with "call page"
Mindcraftmax59:  basically, a function needs inputs, and returns outputs
Mindcraftmax59:  it might not need any input, or not return any output though
Mindcraftmax59:  and that's usually how most people use "call page"
Mindcraftmax59:  but we need to have inputs/outputs for the array
Mindcraftmax59:  so to make a function:
Mindcraftmax59:  WHEN DO input1 equals value; WHEN DO input2 equals value etc
Mindcraftmax59:  WHEN DO "call page" "name of function"
Mindcraftmax59:  and in the call page, you have your function
Mindcraftmax59:  to get outputs, you put WHEN DO "output1" "equals" "value"; etc
Mindcraftmax59:  at the end of the page (or before a "done executing" "call page" that is stopping the page calling)
Mindcraftmax59:  have you understood that part?
Mindcraftmax59:  so Rj?
Rjbull_:  yeh bro!
Rjbull_:  thank you so much!
Rjbull_:  keep going
Mindcraftmax59:  okay, so now for the array implementation
Mindcraftmax59:  it will need two types of functions
Mindcraftmax59:  one type of functions will set the values in the array
Mindcraftmax59:  the other type will get the values from the array
Mindcraftmax59:  and you'll have as many functions for both types, as there are slots in the array
Mindcraftmax59:  so the first type of functions will be "Set Array1" to "Set Arrayn" where n is the length of the array
Mindcraftmax59:  and the other functions will be "Get Array1", "Get Array2" ... "Get Arrayn"
Mindcraftmax59:  and remember that these function names are just the names of the pages
Mindcraftmax59:  in the page "Get Array1", there will be:
Mindcraftmax59:  WHEN "varA" "equals" "varA1"; WHEN DO "varB" "equals" "varB1" etc
Mindcraftmax59:  in page "Get Array2":
Mindcraftmax59:  WHEN "varA" "equals" "varA2"; WHEN DO "varB" "equals" "varB2" etc
Mindcraftmax59:  up to "Get Arrayn"
Mindcraftmax59:  so you can just code "Get Array1", and copy paste the page as many time as the length of the array
Mindcraftmax59:  and change "varA1", "varB1" etc. to "varAslot_number", "varBslot_number"
Mindcraftmax59:  when you call a page "Get Arrayslot_number", it will return the variables "varA", "varB" etc
Mindcraftmax59:  now, for "Set Array1":
Mindcraftmax59:  WHEN "varA1" "equals" "varA"; WHEN DO "varB1" "equals" "varB1" etc
Mindcraftmax59:  yes, it's kind of the opposite of the "Get Array1" code
Mindcraftmax59:  so I think you understand what is the code for "Set Array2" etc now
Mindcraftmax59:  so, before moving on to third part, actually using these functions like you would with a conventional array
Mindcraftmax59:  have you understood that part?
Rjbull_:  yeh bro
Rjbull_:  thanks so much ahah
Mindcraftmax59:  no questions so?
Mindcraftmax59:  do you start to get how it works?
Mindcraftmax59:  because I might stop here, if you really have understood what I'm doing with that code, you wouldn't even need that third part
Mindcraftmax59:  but I'm not going to do that ofc
Mindcraftmax59:  so since now, you can get
Mindcraftmax59:  "varA" "varB" etc (the returned values)
Mindcraftmax59:  you can put code using these variables after calling the pages "Get Arrayslot_number"!
Mindcraftmax59:  you only have one code for all the slots in the array
Mindcraftmax59:  but how to do that? With a "for each of" loop. And remember how I told you the names of the functions were "Set Arraynumber" and "Get Arraynumber"?
Mindcraftmax59:  you can do a "call page" "Set Array" "plus" "number" (same with "Get Array")
Mindcraftmax59:  and of course, you can use the current index of a for each of loop
Mindcraftmax59:  WHEN "for each of" "length of the array" DO
Mindcraftmax59:  (child*1) code for calculating the values of VarA, VarB etc
Mindcraftmax59:  (child*1) WHEN DO "call page" "Set Array" "plus" "current index"
Mindcraftmax59:  this code was for setting the array
Mindcraftmax59:  now for using it:
Mindcraftmax59:  WHEN "for each of" "length of the array" DO
Mindcraftmax59:  (child*1) WHEN DO "call page" "Get Array" "plus" "current index"
Mindcraftmax59:  (child*1) code using the values of VarA, VarB etc
Mindcraftmax59:  that's basically it!
Mindcraftmax59:  and now, you can look at my level "Randomness, the Game". And go in the logic cube "Polyhedron Brain" (if you don't see the names, go in the pause menu -> Options -> Controls -> Show Object Names On)
Mindcraftmax59:  it's an example of the use of this array implementation
Mindcraftmax59:  have you got questions?
Mindcraftmax59:  do you see how you would use it with the inventory?
Mindcraftmax59:  the only part missing from my explanations in order to make an inventory is what is in "(child*1) code for calculating the values of VarA, VarB etc" and "(child*1) code using the values of VarA, VarB etc"
