quick way to create a temporary value and then destroy it - values limit in MMF

As some of you already know fusion has a limitation in the number of value variables you can attach to an object.
And I find this limitation is creating an issue for me right now- as I need to a temporary value for each object type that is being counted with a loop. It adds to it on a loop cycle when counting. Then the result is being moved to another variable and the temporary value is no longer needed.

Is there a way in fusion to use a temporary value that is not attached to any object? Use it and then forget about it?
The number of object types I have in the game is more than the number of values that can be attached to an object. And I am storing the object count in an ini file anyways.
Its the temporary value that bothers me.

The loop cycle object counting doesnt work when trying to create it and add to it when in the ini object for some reason.

Help guys :)

Sure. Simply use a counter for each value you need to temporarily store. You can use another counter to store the fixed id of the current object in the loop, to easily tell which object the stored values belong to.

I dont undertsand :D
Example?

When the loop runs, it needs to write to many temporary values. More than the number you can have attached to an object.

I might be able to do this my storing these temporary values in an external ini file instead - the same where I store data about the objects that are being scanned

Can you give a concrete and simple example of what you're trying to do? What is stored, when is it stored and when is it used again?

That's wrong. Since one of the last builds you have unlimited number of Alterable Value for each object. You can simply access them via their index number at runtime.
But at edit time in the Frame Editor you just can set the Alterable Values from A - Z.

I didnt know about that! :D

is there an example file?

I got it to work by using an the ini object, but this new information is definitely going to be handy !
Are there any plans of making these accessible in the editor?

You can access unlimited Alterable Values:

• Condition: Object > Alterable Values > Compare to one of the alterable values > Use expression (enter or calculate the index)
• Action: Object > Alterable Values > Set > Use expression (enter or calculate the index)
• Expression: Object > Values > Alterable value by index

Very simple. Isn't too hard to find? :o

I don't think that will happen in Fusion 2.5. Hopefully in Fusion 3 and without the fixed order of the variables in the Frame Editor.
But it's planed to include also unlimited Alterable Strings in one of the next builds.

that is great news! Thank you :)

since writing to and reading from an ini file is slower (as Snail pointed out in another thread), I might have to move my ini temporary value creation back to the object i was using before, but instead use the value ID to point to the value. A bit silly of me to write to an ini file during a loop that scans many objetcs. So this new feature/removal of a limitation in fusion that you pointed out is going to be handy in this case!

That said I am really looking forward to Fusion 3, which will hopefully take care of some of the pet peeves in this version :)

The fix order being one of them. Same applies for the locking of ids everywhere I think.
Changing order/deleting or adding frames changes their IDs. Same for layers. Animation sequences, etc. Its all a bit locked down right now

Btw the index is 0-based, right?

Yes. After you clicked "Use expression" there is a notice in the upper right corner of this window.

One last question:

Would the ability to enter an expression for the value name allow me to operate on multiple values at the same time (with one line of code)? What syntax can I use to do that?
is it possible at all?

For example if I want to set all the values of an object to 0 with one tickbox of code.
Or if I want to add +1 to all the values of an object?

Thanks in advance!

ok another question: Can I refer to a value of an object by its name (string value) instead of it's id in the expression of the value?

No. You have to start one Fast Loop for example 1000 times. On loop you set the Alterable Value from the Fast Loop index to your desired value. So you're setting 1000 values instantly. There is no need for an example file. It's straightforward, you can figure it out, just play around.

No.

I see that is clever. Use the loopindex number to point to the value id :D
I kind of overlooked that. This new feature in fusion is really impressive.

Thank you btw, it saved me a huge number of lines

Yes, it's very useful. I'm not sure if it's mentioned in the help file or else where.
But if someone new comes to Fusion 2.5 it looks like there are only 26 Alterable Values.
Unlimited Alterable Values looks at the moment like an insider knowledge.
