  • Hello everyone

    There is an array (in the screenshot). The elements are constantly changing. I need to remove rows with value 0.

    When I run a loop and remove by Y index. Elements deletes incorrectly. When removed, the array is shifted. I tried different ways but they all didn't work.

    It's no problem to remove 1 element but it doesn't work in a loop.

  • It's a little tricky but what I do for this is have the loop inside a function and stop the loop if the matching value is found and then run the function again.

  • Try Construct 3

  • You scared me :) I thought there was an easy way that I didn't think of.

  • Well it's kinda easy, try it out :) it should fix the skipping issue

  • You have to loop over the array backwards. 

    Var i=0
Var count= Array.width

Repeat count times
— set i to count-loopindex-1
— array.at(i) == 0
— — remove array at index i

    Or you can 

    Var i=0
Every tick
— set i to 0

While
i<array.width
— array.at(i) == 0
— — remove index i
— — subtract 1 from I
— add 1 to i

  • Thanks for the advice, I figured it out. This works with pauses in the loop and with the array backwards(although there were difficulties).

    I had quite a lot of experience in PHP programming, there were no problems with arrays :)
