parse int to stylelength

Example of my code: visualElement.style.top = int * buttonVisualElement.style.height;

The error I'm receiving is: Operator '*' cannot be applied to operands of type 'int' and 'StyleLength'

I'm trying to move a visual element by changing its top value.
The value should be the product of button index position * button height.

 

Perhaps int isn't the name of a variable?

 

Because the height property of a style is of type StyleLength. This is a struct which has a value field which is of type Length. Length is also a struct which again has a value field which actually is a float value. So I guess you want to set this float value. Since top is also a property of type StyleLength and that's a struct, you probably want to use the constructor of StyleLength which has an overload that just takes a float. So try something like

Code (CSharp):

1. visualElement.style.top = new StyleLength(int * buttonVisualElement.style.height.value.value)

Keep in mind that those structs are there for a reason. The keyword may constrol how or if the value is used at al. Likewise the Length struct has a unit setting to indicate of the actual float value is a pixel value or a percentage value.

It's difficult to tell what's your exact usecase. However you may just read a bit more in the documentation

 

This is my actual code "m_ActiveTabIndicator.style.top = bindex * clicker.style.height;" for better understanding I wrote it like that.

 

CSharp]visualElement.style.top = new StyleLength(int * buttonVisualElement.style.height.value.value)

This had No error but the desired result is not there. Nothing was happening.

I tried this "m_ActiveTabIndicator.style.left = bindex * 100;" & it is working but I don't want to hardcode the value.

bindex is still an int, I tried a value of 100 in the place of Quering height. it doesn't make sense to me how it is working. Is there any other workaround?

 

So, the answer is

Code (CSharp):

1. m_ActiveTabIndicator.style.left = bindex * int.Parse(clicker.resolvedStyle.width.ToString());

 

Or perhaps finding another way to cast float to int?

So i'm having the same issue. I'm trying to make a tab adjust its height depending on the amount of buttons it has.
I've tried that already:

Code (CSharp):

1. btnPannel.style.height = uiButtons.Count * int.Parse(btnPannel.resolvedStyle.width.ToString());

But it didn't work, so i've tried to print btnPannel.resolvedStyle.width.ToString(), but it says "NaN" (Not a Number).
Any clue as to why?

 

don't you find this at least a little bit silly? and ugly? and useless?
I know this wasn't your idea, I can see the original post, but imagine if I was to convert this message of mine into Alien NeoJapanese, then translate it back. you might still understand it, but at what cost? in other words don't unnecessarily convert values to strings for no apparent reason.

now, why don't you try

Debug.Log(btnPannel.resolvedStyle.width)

and see what you'll get?
then try

Debug.Log(btnPannel.resolvedStyle.width.value)

and then

Debug.Log(btnPannel.resolvedStyle.width.value.value)

we already know the structure of these elements, and we know that they hold a float (number) down the line, so why don't you test these assumptions and see what's going on? once you've done this, come back with the results and we can troubleshoot this together.

edit:
btw if a system tells you something's a NaN (not a number), it really means it, and it has to be true, at least according to some specification on what is classified as number and what is not.
