Hello, I’m trying to get a specific index from my array list. I have tried multiple things but I always fail to achieve my goal. In my blueprint I calculate eight different vectors and make an array of them. Then I would like to calculate their distances to the player location and get the index of …

Ok two points You could make a variable set it to the max value that a float can be (call it something like CurMinDistance), do this outside the loop, then compare your distance, to this CurMinDistance, if it’s less (which is why we set it to the max value, so that it is forced to be greater than …

I’m sorry but I’m really struggling to get this done. Would you be so kind and show me how it’s done? I really want to make it with a For Each Loop and at the end I need the index of the one vector that gives the smallest distance. That vector with the smallest distance is going the be the next cent…

I think that I know what you want, here is what I did: [90335-get+closest+vector.png] I use a function, this bassicly just is vector a - vector b, but it is easier to remember for me. <a name="p-1563229-also-you-need-to-let-closestvector-have-a-high-default-value-and-set-it-to-high-again-if-you-want-to-re-use-thi-logic-you-actually-van-add-this-to-the-completed-part-of-your-for-each-loop-since-you-have-the-index-of-the-array-that-has-is-the-closest-but-it-depends-on-what-logic-it-is-used-for-1" class="anchor" href="#p-1563229-also-you-need-to-let-closestvector-have-a-high-default-value-and-set-it-to-high-again-if-you-want-to-re-use-thi-logic-you-actually-van-add-this-to-the-completed-part-of-your-for-each-loop-since-you-have-the-index-of-the-array-that-has-is-the-closest-but-it-depends-on-what-logic-it-is-used-for-1" aria-label="Heading link"> Also you need to let closestvector have a high default value and set it to high again if you want to re-use thi …

Here is one possible solution. [90361-vectordistance.jpg] .

This is perfect, thanks a lot! I see now why I couldn’t get it to work, also thanks for the detailed description! The array that feeds the for each loop will have to change after some time but that’ll be easy to achieve. Again thanks for your help!
