Strange Array Generation Problem

Development Programming & Scripting Blueprint

Hello Guys,

I’m making a chess game with reference to this tutorial, but I’m stuck in the meterial setting of the chess piece.

Upper blue prints’ result is below.

As you see, I automatically created objects using arrays. And set first 30 objects’ meterial to black.
But result is very weird.

So I checked every objects’ array number, and that’s more strange.

I can’t understand everything…
Where’s 0,1,2,3,7?
Why there’re 5 of 63s?
55~59 before 4?
What the heck?

I tried to solve this couple of days but i didn’t make it.

Blueprint file attached.

Can you show the full BP?

Blueprint files usually cannot be opened if shared like this (.uasset), if they depend on a specific parent class or linked assets (in this case the static meshes), copy an paste your graph/s to websites like blueprintue.com.

In this case I was able to open your file, but some parts are missing, so it’s kinda pointless:

The logic you are using looks pretty confusing to me, did you fill a 64 values array one by one? At this point you could have just used an array of structs with the mesh and the color and avoid all these nodes.

Personal curiosity: What do “==63” and “>30” stand for?
