acting on multiple active named active1, active2, activeX - HOW??????

[cfullerNY]

i believe i have the correct logic for what i want to do, but i just don't know how to implement in mmf2.

seems like it might be similar to "pointer" in C? i need to both retrieve value from memory AND point to address space of that memory

i would be very appreciative for any help you can provide, forum.

i have 10 items and 10 beds

A) saving:
if item[X] collides bed[X]
and
bed[X] is empty (alterable value A of bed[X]=0)
then
set the item[X] in bed[X] (save the "X" of item[X] to bed[X] alterable value A)

if bed[X] is not empty (if bed[X] alt val A=0), don't do anything to bed[X] alt val A

B) loading:
at start of frame, check bed[1] through bed[10] to see if it has value 0 or >0
if 0, do nothing
if >0, move item[X] to bed[X]

i know how to do this conceptually but in practice i'm having trouble implementing in mmf

i want to use fastloop and counter

so i have counter named "loopcounter" set to 1 and loop named "loading"
i run loop "loading" 10 times
on loop "loading", check bed[1]=1, if bed[1]=1, then place item[1] at bed[1]
on loop "loading", check bed[1]=2, if bed[1]=2, then place item[2] at bed[1]
...
on loop "loading", check bed[10]=10, if bed[10]=10, then place item[10] at bed[10]
on loop "loading", add to loopcounter +1

my issue is that i don't know how to interface with MMF so that I can use expression editor to write "bed[X]". i only know how to address one object i.e. bed1, bed2, bed3. it becomes many lines very quickly :P

other related problem:

i'm using numbers array and numbers counter... this one makes absolutely no sense to me. very frustrating.

thank you for your help, forum.

You can use the Spread Value action to give each active object a unique value starting at the value you want. You can then use the ForEach obejct to loop through and save each one. You will also want to save how many you saved. Then you can later load it again by crating the correct number of objects and using spread value, then using ForEach to loop through them again. The spread value should, in both cases, be used as the ID to differentiate different saved objects in the INI.

As for pointers, the closes MMF2 has to that is that every object has a Fixed Value, but you should not use this for identifying them across saves because they can change unpredictably.

but isn't 'spread' only for multiple duplicate active obj? i have 10 active object named item1, item2, item3, etc. i have 10 active object named bed1, bed2, bed3, etc.

each active is unique and is placed in a unique XY position in the frame. they are not the same object.

let me ask you a new question please, LB:

if i just make one bed active, named bed, and place it 10 times in 10 different places, and then i run spread ID, will it spread ID in the same pattern each time?
so lets imagine grid of beds, 2 row and 5 column
start of frame, spread ID to alt val A of bed
will top left bed always be (0 or 1 i don't know how index starts)? or will it be random?

i must learn ForEach today.

Spread value is guaranteed to give the oldest objects the highest values and the newest objects the lowest values, and the values will always be the same if you never create or destroy between spreading. You can always, after spreading from 1, set the object's Alterable Value to NObjects-Alterable Value to get the oldest object at 0 and the newest object at NObjects-1

On my website I have a Node Example that shows exactly what LB was saying.

i believe i understand what to do now. thank you very much for your help, i now understand spread.

and it is beautiful! I LOVE MMF!!!!!

Another thing you might want to look at is "Qualifiers". These are properties which can be assigned to groups of different objects and can allow you to work with them as a whole.
