Use some values from other value list

jc4d — Tue, 25 Oct 2022 07:03:23 GMT

Hello,

I have one values{2} list containing some model types and a second values{2} containing all the possible dimensions among all the models.

Now, the thing is that depending on the selected model type it could use some of the values sets on the second list.

For example, I have 3 model type and the dimensions that all of them altogether could use are 6 different sizes. Now when I choose the first model type, only the first 3 sizes should be displayed in the parameters, if I choose a second model type, then that one will use only the last two sizes from the second list... I really hope all this makes sense.

I have setup a starting script, but not sure how to tell to each IF condition to display some values from the main size list.

VALUES{2} "model_type" 1,"ORIVENT 51", 2,"ORIVENT 21", 3,"ORIVENT 23" VALUES{2} "all_base_hgt" 1,"200", 2,"350", 3,"400", 4,"750", 5,"900", 6,"1100" !!! Problem, how to "call" some of the values from "all_base_hgt" to each IF condition IF model_type = 1 THEN VALUES{2} "base_hgt" 1,"400", 2,"750" ENDIF IF model_type = 2 THEN VALUES{2} "base_hgt" 1,"400", 2,"750", 3,"900" ENDIF IF model_type = 3 THEN VALUES{2} "base_hgt" 1,"400", 3,"900" ENDIF

You don't need the parameter 'all_base_hgt' as you are setting the parameter 'base_hgt', and that seems to be working just fine depending on the model you choose.

Thanks, yeah that's how I got it working in the beginning, but let's say that the value in the second values{2} list changes, I would have to go throught all the IF to update them, and I would like to have a more parametric way to deal with. Hope it makes sense.

Edited the code here with the right comments on what I'm going after:

VALUES{2} "model_type" 1,"ORIVENT 51", 2,"ORIVENT 21", 3,"ORIVENT 23" VALUES{2} "all_base_hgt" 1,"200", 2,"350", 3,"400", 4,"750", 5,"900", 6,"1100" IF model_type = 1 THEN !!!!Access here the index 1 and 3 from all_base_hgt ENDIF IF model_type = 2 THEN !!!!Access here the index 1,2 and 3 from all_base_hgt ENDIF IF model_type = 3 THEN !!!!Access here the index 5 and 6 from all_base_hgt ENDIF

I don't think you can pick and choose values from a value list to use in another value list.

Maybe you need to create an array to store the values and then populate the value lists from the array values?

Now I got lost 😅.

Is there any example out there in the wild that I can check?

This seems very round about... Why not just use VALUES instead that point at variables? Then have your use cases later point at those same variables, rather than trying to make the descriptor a variable, which is not nesessarily actually relevant later. In your current case base_hgt = 1 might actually be resulting in using a value of 1100 instead of 200. Usually you would be using VALUES{2} to provide a name of some options such as a type of joint type or skirting type.

v1 = 0.200 v2 = 0.350 v3 = 0.400 v4 = 0.750 v5 = 0.900 v6 = 1.100 IF model_type = 1 THEN VALUES "base_hgt" v3, v4 ENDIF IF model_type = 2 THEN VALUES "base_hgt" v3, v4, v5 ENDIF IF model_type = 3 THEN VALUES "base_hgt" v3, v5 ENDIF

That's great workaround, the idea behind using VALUES{2} is that the designers always change their mind on the therminology used in the parameters, so having control over the names on a centralized way has saved me huge amount of hours.

I will give it a spin to your solution to see how it adapts to my idea 👍.

What I ended up doing (not to my liking, keeping track of one change into so many places) is this:

I was trying to use the subroutine way, but couldn't wrap my head around 😂

If you use only dimensions, I think Lingwisyer suggestion to use simple value is the best. Because looking at your screenshots base_hgt has same int value that stands for different dimensions...

If you do want to use values{2} I'd try to use "integer variables" instead of actual integer numbers.

for example:

Master script:

base200=200

base400=400

...and so on it doesn't have to be only 1,2,3,...

tbh redundant if basically difference is only dimensions (can skip it)

parameter script:

values{2} "base_hgt" base200, "200", base400, "400",...

or straight if skipped master

values{2} "base_hgt" 200, "200", 400, "400"

in that case chance of mistake is lower. plus you always can make nice conditions (because "base_hgt" has integer type), kinda

if base_hgt = 400 then _code_

just be careful when use that variable base_hgt for modelling (because of picking actual values 200, 400, not straight forward 1,2,3 you can use it there too) not forget to multiply by 0.001

For values lists based on another value list you can do some sneaky stuff!

values{2} "modeltype", 1, "Model 1", 2, "Model 2" dict cs cs.sizes[1].s[1] = 100 cs.sizes[1].s[2] = 200 cs.sizes[2].s[1] = 150 cs.sizes[2].s[2] = 300 cs.sizes[2].s[3] = 450 values "sizes" cs.sizes[modeltype].s

A small breakdown of whats happening in this brilliant hack (brilliant because it's working due a nice language feature, the DICT, that founds its way into GDL):

We declare the models and assign a number to them with values{2}, which we will then use as an index for the first level of the dict which happens to be an array. Luckily for us you can stuff an array inside the array (here called just "s"). So you'd put all the applicable sizes into "s".

A last "values" command and you're good to go. Achieving a lot in a few elegant lines of code.

@runxelwow, great solution, thank you for your time and knowledge 👍.

I'm having a braint fart here (I'm jumping between Python(some blender stuff) and GDL). sorry for that.

Now that we have the values displayed in the parameters, how to tell to e.g. a brick object to change their ZZYZX accordingly?

Thank you for the tips, will check it out.

Re: Use some values from other value list

jc4d — Wed, 26 Oct 2022 07:08:46 GMT

Ok, brain fart time is over, on the Master Script:

ZZYZX = base_hgt*0.001

Thanks to @A_ Smith for the 0.001 tip.

I hope this question is relevant to the same topic, otherwise mods can move it.

Let's say that the designers don't want to see any numeric value in the parameter list, instead they want to see a text (string) and that string is associated to a dimension in the dictionary.

Is there a way to do it?

This is a mockup idea (I know it doesn't run)

dict cs cs.sizes[1].s[1] = "low model" cs.sizes[1].s[2] = "High model" cs.sizes[2].s[1] = "Mid size model" cs.sizes[2].s[2] = "Other custom strgin"

The "Low model" has a associated dimension of 100, "High model" a dimension of 200, "Mid size model" 150 and "Other custom string" 450.

It is in this type of situation in which you would use VALUES{2} as you are displaying descriptors rather than actual values. Using a similar method to Lucas you could use the result from this to pull the relevant values from an array if your options are based on the same basic shapes. Am unsure what will happen if your VALUES{2} does not step by 1, but if that is not a requirement, you might be able to skip a step?

Idk how to use dict. I assume it's more accurate.

though if problem is only in variables naming you can do sometimes like this

Re: Use some values from other value list

runxel — Thu, 27 Oct 2022 09:20:26 GMT

Another take on the case with very easy adjustments:

values{2} "modeltype", 1, "Model 1", 2, "Model 2" dict cs cs.sizes[1].s[1] = 100 cs.sizes[1].t[1] = "Short" cs.sizes[1].s[2] = 200 cs.sizes[1].t[2] = "Tall" cs.sizes[2].s[1] = 150 cs.sizes[2].t[1] = "Grande" cs.sizes[2].s[2] = 300 cs.sizes[2].t[2] = "Venti" cs.sizes[2].s[3] = 450 cs.sizes[2].t[3] = "Just normal coffee pls" values{2} "sizes", cs.sizes[modeltype].s, cs.sizes[modeltype].t

Since the user never sees the index numbers from modeltype there never should be a case where they are not consecutive. But if they are: As long they are integers and bigger than zero it should be fine. Archicad would fill the missing gaps between in the array.
