simple loop issue

[Kingdom Ablaze]

so what i wanna do is eliminate the nil values. but my problem is im not sure how to handle two nil values in a row. here is what i have

 

for i in 1...array

    if array[i] == nil

       i +=1

    end

    #do the rest of the method, the error would be here because the second nil value made it through.

end

 

i know this is so simple but its driving me crazy

replace the "i += 1" with "next" (i.e. skip this iteration if array == nil)
the 'for' loop will increment i, so you don't need to inside the loop

that totally fixed all my problems, took me 2 hours to trace problem back to that stupid line, thank you so much brew, thats why you are one of my heros

Eh... couldn't you just use ary.compact! ??? AFAIK you just need that single line of code to perform such a common task.

well to be honest it wasn't an array, just wanted to simple down the problem

Well, let's say it's a hash, it'd be done like this...

some_hash.delete_if {|k,v| v.nil?}
#=> all key-value pairs that weren't deleted

Just check if RGSS includes that method.
