loop blocks around some point.

I trying to create code that will be checking all blocks around some location - only on this same Y axis.

EQ: I must found nearest yellow block from that diamond-block, but i don't know where are yellow blocks: (any of that 3 near center)


I can checking larger, and larger area every time... but that isn't fast - checking this same blocks multiple time.

 

Try rewording your post, I don't understand what you want.
Do you want a method that generates spirals?

 

not generate, only loop.
Just find that nearest yellow block :<

So i must checking that blocks until I find one of yellow-blocks (I don't know location of any yellow-block)

But how?
Checking areas like 3x3, then 5x5, 7x7 will be too slow - it will be checking this same blocks many times.


So how to do that faster?

anyone?
