Sensitize gdl object to story level

[Bhtsz_pyd]

Hello, I'm new to Gdl.
I have an object in my hand. I want to make a gdl object where I can choose which floor level this object will be at. However, I could not write a suitable code for this. There is the feature I want in the elevator object, but the gdl codes were too complicated for me. Which command should I use for this?

Thank you.

Hello @Bhtsz_pyd ,

You would need to REQUEST the STORY_INFO global variable. It holds info on all stories including the names, elevations and heights.

n = REQUEST("STORY_INFO", expr, nStories,
            index1, name1, elev1, height1 [,
            index2, name2, ...])

Thank you MF BIM for your reply.
Obviously I tried that, but that's where your problem starts. What I want to do is to create a parameter that I can choose between. Ground Floor Plan, 1st Floor Plan, 2nd Floor Plan and link the position of the object to that floor. With the code you mentioned, I can get data such as story name or story height. I can also write it to the screen with the Text2 command. However, I cannot create a parameter that I can choose between them. Is there a sample video you can suggest about this? Creating a parameter similar to the “car position” parameter in the elevator object.

Hi,

the additional code you need is:

n = REQUEST ("Story", "", index, story_name)
Returns in the index and story_name variables the index and the name of the current story.
n = REQUEST ("Home_story", "", index, story_name)
Returns in the index and story_name variables the index and the name of the home story.

you cannot physically move the object to a different story using the GDL code, but you can move where it appears in floor plan, and 3d Position using the code...

i.e.

n_current = REQUEST ("Story", "", index_current, story_name_current)

n_home = REQUEST ("Home_story", "", index_home, story_name_home)

nn_current = REQUEST ("STORY_INFO", index_current, total_stories, Index_Of_current, Name_Of_current, Elevation_Of_Current, Height_of_Current)

nn_home = REQUEST ("STORY_INFO", index_home, total_stories, Index_Of_Home, Name_Of_Home, Elevation_Of_Home, Height_of_Home)

nn_Ground = REQUEST ("STORY_INFO",0, total_stories, Index_Of_Ground, Name_Of_Ground, Elevation_Of_Ground, Height_of_Ground)

nn_First= REQUEST ("STORY_INFO",1, total_stories, Index_Of_First, Name_Of_First, Elevation_Of_First, Height_of_First)

nn_Second = REQUEST ("STORY_INFO",2, total_stories, Index_Of_Second, Name_Of_Second, Elevation_Of_Second, Height_of_Second)

and then you have the ability to calculate position/display based on designated story.

you can then have a parameter that has the story you wish to display

show_on_story

i.e.

values "show_on_story" "Ground Floor Plan", "First Floor Plan", "Second Floor Plan"

!2D Script

n_current = REQUEST ("Story", "", index_current, story_name_current)

if show_on_story = "Ground Floor Plan" and index_current = 0 then

    !Show 2d content for ground floor option here

endif

if show_on_story = "First Floor Plan", and index_current = 1 then

    !Show 2d content for First floor option here

endif

if show_on_story = "Second Floor Plan", and index_current= 2 then

    !Show 2d content for Second floor option here

endif

@Bhtsz_pyd,

If you want to move the car then I would do it like this :

- Have an CarElevation parameter (length type)

- Have a CarPosition parameter (integer type)

- Request the story names and elevations after you requested the story info) and use VALUES{2} to display them as a drop down menu

- After selecting the CarPosition, calculate the sum of the elevations up to the chosen story

- Give that value to the CarElevation parameter to move the car

If you're new to GDL, you may need to go there to get some of the basics : https://gdl.graphisoft.com/gdl-basics

@MF BIM @AllanP 

Thank you both very much for your response. However, I think I asked my question wrong. The question I am looking for an answer to is to create an infinite loop “values{2}”
i.e.
values{2} “stryname” , 1 , Ground Floor Plan,
2, First Floor Plan,
3, Second Floor Plan

I can write this manually, but depending on the size of the project, sometimes it can be a 10-storey project, sometimes a 20-storey project. Every time I add a new floor to the project, I want that stories to be added to the parameter automatically.

You could PUT all of the values into a parameter through a loop using nStories from your Request. From there you can use GET to insert it into your VALUES{2}.

n = REQUEST ("Story_info", "", nr, ss)

FOR i = 1 TO nr
!nr = STR ("%.0m", ss [4 * (i - 1) + 1])
!name = ss [4 * (i - 1) + 2]
!elevation = STR ("%m", ss [4 * (i - 1) + 3])
!height = STR ("%m", ss [4 * (i - 1) + 4])
