I want to use

http://modelling4all.nsms.ox.ac.uk/Resources/Composer/en/MB.2/INITIALISE-ATTRIBUTE.html

to set multiple attributes e.g. like is happening here:

http://modelling4all.nsms.ox.ac.uk/Resources/Composer/en/MB.2/SET-WORLD-SIZE.html

but i don't understand the syntax.

i made a start here:

https://weblearn.ox.ac.uk/access/content/user/14894/SET-ATTRIBUTES

but can't see how to change the last line

Hi.

One way to do this all in one micro-behaviour is to edit to be

substitute-text-area-for the-power-s0 85 
substitute-text-area-for the-power-s3 5
substitute-text-area-for the-power-s4 3 
substitute-text-area-for the-power-s5 2
set my-power-s0 the-power-s0
set my-power-s3 the-power-s3


set my-power-s4 the-power-s4
set my-power-s5 the-power-s5
But perhaps a better way to do this is to copy INITIALISE-ATTRIBUTE 4 times. It is more modular (perhaps someone will want to add S1 or S2).


Best,
-ken


P.S. There is a trick to using substitute-text-area-for  -- the first argument should be the string that is replaced by a text box. So


substitute-text-area-for my-power-s0 85
or
substitute-text-area-for power-s0 85
would substitute the box for the first argument to SET rather than the desired secoond arg.

I changed the micro-behaviour as suggested but the behaviour composer
throws errors:
https://weblearn.ox.ac.uk/access/content/user/14894/SET-ATTRIBUTES

Could not find the-power-s0 in substitute-text-area-for the-power-s0
85 substitute-text-area-for the-power-s3 5 substitute-text-area-for
the-power-s4 3 substitute-text-area-for the-power-s5 2
Could not find my-power-s0 in substitute-text-area-for the-power-s3 5
substitute-text-area-for the-power-s4 3 substitute-text-area-for the-
power-s5 2

i tried changing the code to say my-power instead of the-power but
this brings the same error.

i prefer to set multiple attributes in one micro-behaviour simple to
keep the number of MBs smaller and make editing them all easier e.g.
need to click few times to change all attributes.

It seems that something inside of the Behaviour Composer is sensitive to improper HTML. I took your file and cleaned up some of the HTML and it works fine. Here it is.

Best,

<EM>I set a range of configurable attributes.</EM>

<P>
<EM>Here we can initialise attributes relating to an agent e.g. a power-consuming&nbsp;device such as a com&nbsp;</EM>
