What are the minimum requirements for a “for this sprite only” variable's value in the main sprite to be accessed and changed by clones?

The minimal requirement is a “for this sprite only” variable.

Here is an example, each clone has a health value from the “this sprite only” variable. As you click each one they can change the value of their health.

Here is a project I made during Getting Unstuck with teachers group. This uses an id system so each clone has a number, then each of the for this sprite only values are changed in the lists. Press space to see the list of values changing. All variables are “for this sprite only” the lists are "for all sprites'

Can you explain a little more about what you mean?

Like for some for-this-sprite-only variables, there is a different value for every clone and for the other ones the value is shared between clones and the main sprite.

The for all sprites (global) variables everyone in the project can see. For this sprite only (local) variables are only seen by that sprite or clones of that sprite who the variable was made for.

Not quite, though, there is a very neat work around. Hope you are good with lists.

It's a bit more complicated, but will get you the exact result you want.
First, create a new list for all sprites:


Next, create a new variable called “clone #” for this sprite only:


Then, when you create a clone, just set “clone #” to a certain value.
So, if you want to increase the value as you create clones (hope you get what this sentence means), just do something like this:


Now, let's say that you want to store a clone's x (1 data set) and y position (2 data sets), you would get their positions from the list like this (there's another easier way, but this one is the mathematical way):

(item ((which clone's datas you want to get::grey)*(number of data sets, in this case, 2::grey)) of [list v] :: list)// This is the FIRST step.
//The previous script gives you the first data from the entire data set that belongs to that clone.
(item (((which clone's datas you want to get::grey)*(number of data sets, in this case, 2::grey))+(a number between 1 and the number of data sets::grey)) of [list v] :: list)
//That was the last step, and you're done if you've followed everything correctly.

Hope this helps. Let me know if you have any questions, this is a little confusing.

Well I know about that, but sometimes every clone has a different value in “for this sprite only” and other times the main value from the main sprite can be accessed and modified by clones. I don't want to work-around it, I want to use the requirements for the main value to be accessed by clones.

I'm trying to make a project where it's only clones.
I have experience in using clones dynamically.

I'm confused

I am also confused. Maybe sharing the project so we can see what you are trying to accomplish can help with the confusion.

Use the block right under the reset timer block in sensing

([variable v] of [Sprite1 v])
