  • So basically, at the start of the layout, I have an event that lists the names of .dat files in a folder to a listbox, then I have an subevent that happens immediately afterwards:

    ListBox: 494 For each line

    ListBoxSet line ListBox 0 .CurrentIndex data to GetToken(ListBox 1 .LineText(ListBox 2 .CurrentIndex),1, ".")[/code:7y7v5245]

    Basically this should strip every line from the ".dat" at the end of it, but for some reason, it doesn't seem to work. It works if I change "Set line data" to "Add line", so the "For each line" is most certainly run, but it doesn't seem to edit the line data for some reason. Later, when I try to do this (still a subevent to "Start of layout"):

    ListBox: 494 For each line
System: 0 ListBox 0 .LineText(ListBox 1 .CurrentIndex) Equal to global('language')

    SystemSet global variable 'languageindex' to ListBox 0 .CurrentIndex

    ListBoxSelect line ListBox 0 .CurrentIndex[/code:7y7v5245]

    It doesn't seem to work either. I basically want to look for a line that is equivalent to the global string 'language' and set a global value called 'languageindex' to the line number of it, yet it doesn't change the value of 'languageindex' at all. Neither of these events do not work even if I put them as independent events instead of subevents.

    Any help?

    EDIT: Okay, so apparently LineData != LineText. I managed to partially fix it by changing it to LineData, but then it wasn't working when I tried to read the LineData later on. Now, the real question is: Why the heck can you not alter the actual line text?

  • I don't think many people have played around with the application side of Construct, apart from maybe me. Even I haven't really done all that much with it apart from creating some very basic data storage fields, mainly as a proof of concept.

    Unfortunately, I don't think I even used the listbox object at any stage... so I'm afraid I won't be much help, sorry.

    Maybe one of the dev's can shed some light on this?

  • Set line data associates data with a line. So if you had a list of names you could set an e-mail to go with each line which wasn't visible, for example. It won't change the item name.

    As the copy as text is a bit dodgy, it'd help if for the second issue you uploaded a .cap file. But there is a FindLine expression; you don't need to do a for each loop and check the text.

  • Rich, what I basically wanted to do was turn a list with this:

    english.dat

    finnish.dat

    Into this:

    english

    finnish

    I figured out that LineData is separate thing from LineText, but now my question mainly is that why can't I alter the actual LineText, only LineData?

    Construct in general is missing quite a lot of things in regard of creating applications (and using application rendering), but those really belong to a separate topic, and this particular problem was about doing a multilingual game. In any case, I managed to get around this by adding my edited lines to another ListBox, but in the future it'd be nice not to have to do this.

    There is no API function to replace the text of a line. What you should do is add them how you want them. There is a 'For each file' condition of the File object, for example. You could use this and strip the '.dat' out before you add the file.
