Request - Current Story Height

MuriloNoleto — Wed, 31 Aug 2016 12:08:07 GMT

Hello everyone,

I have been doing tests in 2D script about REQUEST options, when I write this text:

n = REQUEST ("Story_info", expr, nStories,index1, name, elev, height)

text2 0,0, height

In 2D preview, the value "height" shows the height of Ground Floor. In this case, I want that it shows the height the current floor (if some project has many stories).

In versions before AC 20 the GLOB_CSTORY_HEIGHT variable was a solution.

What do you suggest?

Thanks in advance.

GLOB_CSTORY_HEIGHT should still be fine if used in the 2D script.
Just don't use it in the Parameter (or Master) script.

Thanks Barry!

Now, if we bring this example to Parameters script.

n = REQUEST ("Story_info", expr, nStories,index1, name, elev, height)

parameters cstory_height = height

When I go to Parameters List, the value of cstory_height parameter (that I have created) is always of the ground floor one.

Is there a simple way to replace the info about the Current Story?

From the GDL manual is says ...

If expr is a numerical expression, it means a story index: only the number of stories and the information on the specified story is returned.

So if you have 'expr' and a number (say 0) then you will get info only for the storey starting at story 0.
Not sure how this works in the USA version as there is no 0 story.

If you set it to 1 then you will get info for story 1.

I think your problem will be you can't REQUEST the story because that can only be done in the 2D script - where you then can't save parameters.
You can't REQUST the current story in the parameter script because this can no longer be done.

If you set 'expr' as a string then you can get all info for all storey as an array.

Again from the manual ...

DIM t[]
n = REQUEST ("STORY_INFO", "", nr, t)
FOR i = 1 TO nr
nr = STR ("%.0m", t [4 * (i - 1) + 1])
name = t [4 * (i - 1) + 2]
elevation = STR ("%m", t [4 * (i - 1) + 3])
height = STR ("%m", t [4 * (i - 1) + 4])
TEXT2 0, -i, nr + "," + name + "," + elevation + "," + height
NEXT i

REQUEST Story_Info will work in 2D and parameter scripts.

I just don't know a way that you can find the current story in the parameter script so you can save a parameter with the height for that story.

I got it!!!!

The solution of my case was to use the "Story_Info" request (as you told me) and creating parameters (with arrays) using the request extracted data.
After that I called the "Home_story" request in order to get the proper "index" of current story.

With a combination of this parameters I could find the current height.

With GLOB_CSTORY_HEIGHT things were pretty much easier. Now the road is more winding.

Thanks Barry for help.

im a little late to this but the elevator object is where i learned how to do all of that with the stories. I use it in so many objects.
