How does loop index work with a dictionary object key loop?

Hi,

I think in construct 2 I can do the "Loop index" check and it will properly return the loop index of a loop I set with the Dictionary Object/For Each loop per key action, but I can't get this to work in Construct 3.

I think this is due to the syntax change in C3.

C3 Seems to force additional syntax with parentheses and "..." which I assume is to be able to enter the name of a specific loop to text for that loop, but you cant name a Dictionary object for each key loop and when I delete the parentheses so there's no name it acts as though there's no syntax problem but the check fails... it does not successfully check the loop index.

Any ideas?

Thanks.

I'm not sure if the loopindex expression works with the Dictionary.ForEachKey condition.

Within a dictionary loop you can use Dictionary.CurrentKey and Dictionary.CurrentValue expression to access the current key/value pair for the the loop. If you want to nest loops then perhaps use local variables to hold the values of the parent loop.

The problem is I can retrieve the name of the key or the actual data in the key, BUT there's no way to get what loop index. :( This is the info I need.

Is the only solution really to make a value and manually increment it in the loop?

An index doesn't have much meaning in a dictionary. The order of the entries is not guaranteed so you can't get/set values at an index.

What are you using the index for? Might help come up with an alternative for you if we could know how you are using the dictionary.

I'm loading tile map data from a file into a dictionary object, so that I can load the data per dictionary key (as json) into each specific tile-map object (one per layer of scrolling)

So, if I could have kept track of the loop index of the fore each key loop that would have been very clean and simple.

The simplest solution is a variable to keep track of the loop index, which is a shame, but not the end of the world.

That won't work for my needs, BUT can you please explain the "(...)" that is forced at the end of LoopIdex in Construct 3? I can't find any documentation of it and it's completely crippling my progress. Is it for a name of a loop index? What about all the types of loops you can't name like the For Each loop for an object?

So in human English you're saying I can delete the "(...)" part and it should work if there is a loop currently looping? ;)

What do you mean by "0 or 1 parameter"? What parameter? Is there documentation? What goes there? The name of a loop or what? if so, what's the syntax?

loopindex only works for system loops like repeats and for loops.

The loopindex parameter lets you specify the name of a for loop.

loopindex does not work for Array "For each xy" and Dictionary "For each key". Each object has its own way of getting the current index by expression.

It worked this way in Construct 2 as well.

For your use case, an array seems more suitable.
