Nested IF in a SET Function - what am I doing wrong?

CharlieGirl · 14 Jul 2010, 02:46

Hi everyone. I'm pretty new to SketchUp so I apologize in advance if this is a dumb or repeat question. I did search pretty much all day and have not found the answer yet, so I'm hoping someone can help me. Here is what I am doing. I have created a dynamic component that is a wall with various types and colors of cladding. I have created my "swatch" of colors/textures and I have attached it to my wall. I bundled the wall and swatch as a component. I have a user input drop-down at the parent level which asks the user if they want siding, brick veneer, stone veneer, or stucco. Each response has a value, 1-4. At the "Wall" child level I have an "onClick" Behavior that should allow the user to click through the various looks and shades for each of the cladding types based on their answer from the drop-down. To do this, I used the SET function but then nested IF statements within. It is going to the correct part of the SET function, but instead of cycling through the types of materials, it is trying to find a material with the name of the entire set. Here is a small example of what I am doing and how SU is responding: SET("Material",(IF(AG Wall!Ext_Cladding=1,("Siding_Light","Siding_Color_Med","Siding_Tan_Med","Siding_Dark"),IF(AG Wall!Ext_Cladding=2,("Brick_Light","Brick_Tan_Medium","Brick_Medium","Brick_Dark"),IF(AG Wall!Ext_Cladding=3,("sketch-stone_Light","Stone_Med","dark-sketch-stone"),("Stucco_Light","Stucco_Med","Stucco_Dark")))))) When, for instance, my user selects "Stucco", this is resolved to "4" but the "Material" Behavior displays Stucco_Light","Stucco_Med","Stucco_Dark just like that, without the beginning and ending double-quotes. So I know it is getting to the correct place, but why doesn't it read the list as a list and click through the options? I appreciate any help!

220 people so far have read this, but no one has replied. Does anyone have ANY ideas about this? I really appreciate any help with it. Are there Google SketchUp programmers that watch this forum? Do I need to contact Google directly? Help!

I read the original post once and thought it was too complex try and debug in a short amount of time. But I know its frustrating not getting help. So lets look at this. Do you have the component, or a test component you could upload here for us to look at?

And to recap, what basic idea you want to have happen. The user chooses a material from a list and it gets applied to the component? Is it more than that?

I agree with Chris.
The question is too complex.
Supply a skp and some simple step-sheet explanations of what you expect the user to do and what should happen and what is happening - forget too much 'coding' initially...
Then we can help you...

Thank you very much. I have attached my wall dynamic component.

What I am trying to make happen is this:

The user selects a siding type in the Component Options dialog box, brick, stucco, etc.
The user interacts with the component by clicking on the wall and the wall cycles through the appropriate swatches to display the siding type as either light, medium, or dark.

I have the swatches attached to the component and it works when I cycle through only one type, but when I nest my If statement, it stops working.

I really appreciate you taking another look at this!

ok, so the user can select one a few different types of materials from a drop down menu. Then by clicking ont he component, the component should switch between light, medium and dark variations of the material.

That should be do-able. I'll see if I can look through the component when I get a chance. Thanks for posting it,

ok, assuming I understood the problem at hand, I went ahead and made a DC that does what you want. The user can choose one of 4 colors from a list. Then upon OnClick'ing on the component, it changes between dark, medium, and light of that color. I'll attach the DC and you can check it out. Or if I get a chance, I'll look yours over and see if I can spot the error.

Yes, you understand the desire perfectly. Thank you so much for your help! I'll look at what you created and compare it to mine to find the error. I really appreciate the time you have spent to help me out. I'll report back what I find (I'm sure I screwed something up!).

CharlieGirl · 11 Aug 2010, 15:28

Thank you! Your example code showed me that I should separate the material selection from the on-click function - I was trying to do too much at one time. I now have the nested IF for the material selection and the SET function is changing the color shade. That, plus for some reason it seems that I need to have a space between the front and back quote marks and the material names, seems to have fixed the issue. I really appreciate you revisiting my problem for me. Thank you again.

Oh good, glad you were able to look through my code and find the help you needed. I find that reading other people's DC code is often tedious...so I'm glad you were able to see what you needed.
