Just wondering why this code crashed my UE if i delete it it works fine but if i press play with this in my code it freezes

int32 i = 0;

    while (i < 2)

    {

        PrintLine(TEXT("%i"), i);

    }

    for (int32 Index = 0; Index < 2; Index++)

    {

        PrintLine(TEXT("%1"), Index);

    }

    int32 j = 0;

    do

    {

        PrintLine(TEXT("%1"), j);

        j++;

    } while (j < 2);

The first while loop never exits because i is always less than 2 so keeps spinning add i++; in that loop like you have with the do loop and it will exit once I gets to 2

ahhh yes thats is, it works fine now i also changes the %1’s i had to i%

All done it :slight_smile: also the classic l and 1 looking the same is another.

you can legitimately use while == true closed loops just need to be very careful and deliberate, its quite fun to write a simple class that opens a port to listen on in one process and keep that open with while true then you can connect to it with another process and send stuff between the 2.
