Get position of the element of the array (SugarCube)

NotDrunk · October 2016

How to get position of the element of the array and put it in a variable when you press the button?

So, we have an array with objects inside. Just for example:

Here is the code to display this array (objects set previously, of course):

<<for $y = 0; $y < $moduleArray.length; $y++>>		
	<<for $x = 0; $x < $moduleArray[$y].length; $x++>>		
		
		
		<<set $moduleArray[$y][$x].xy = ($y + ',' + $x)>>	
	

		<<button "<<= $moduleArray[$y][$x].xy>>" >> 		
			
					
			<<set $currentPosition.xy = $moduleArray[$y][$x].xy>> <-This, of course, does not work. The question how to make so that worked.
		
					
			<<script>>		
		
			Dialog.setup("Module", "module");
                        Dialog.wiki(Story.get("modCreate").processText());
			Dialog.open(null, function() { Engine.show() } ); 
	
			<</script>>
			

		<</button>>
		
		

	<</for>>
	<<= "<br><br>">>
<</for>>

p.s. I apologize for my English

Since you're attempting to use two variables ($x, $y) whose values change within the body of the <<button>> macro, which is only executed much later when the player clicks upon it, you must capture the current values of the two variables as part of the <<button>> macro's invocation.

For example, something like the following should work:

<<for $y = 0; $y < $moduleArray.length; $y++>>
	<<for $x = 0; $x < $moduleArray[$y].length; $x++>>
		<<set $moduleArray[$y][$x].xy = $y + ',' + $x>>
		<<=
			  '<<button `$moduleArray[$y][$x].xy`>>'
			+ '<<set $currentPosition.xy = $moduleArray[' + $y + '][' + $x + '].xy>>'
			+ '<<script>>'
			+ 'Dialog.setup("Module", "module");'
			+ 'Dialog.wiki(Story.get("modCreate").processText());'
			+ 'Dialog.open(null, function() { Engine.show(); } );'
			+ '<</script>>'
			+ '<</button>>'
		>>
	<</for>>
	<br><br>
<</for>>

Additional notes:

Use a backtick expression (top of the linked document) to yield the value of the button's link text, rather than using a print macro.
You do not need to print your two <br> elements.

Thank you very much, it works. Previously I tried to do something similar, but apparently got confused in the quotes.

That can happen, unfortunately.

I'd like to be able to make capturing values easier one day.

Howdy, Stranger!
