file writing (more of general lua I know)

[Pendrokar]

I am working on a building template widget. And I will need a database file where templates would be put.

It would look like this -

Code: Select all

gamename - ba
uniticon - <setuniticon>
templatename - <mytemplate>
new <unitdefid>, <unitname>, <facing>, <posx>, <posz>
new <unitdefid>, <unitname>, <facing>, <posx>, <posz>
new <unitdefid>, <unitname>, <facing>, <posx>, <posz>
...
<another template>
<another template>
...
--|

"--|" ends templates adding to the particular game

I try to save/add templates with file: like this

I dont really know if that works haven't tested because I don't have Spring at work. But the question is about overwriting lines. Because there can be the option to change template name so I have to modify the file where I need to overwrite a line but not when adding a template.

Or can someone point out a easier way? such as adding a LUA file which has arrays added? Though writing to files would still be needed.

look around, iirc spring already handles writing to files, check widgethandler for configuration dumping.

lua tables will be easiest, since you're just an include away from having the data parsed and ready to use.

Here is an example, writes out a Lua file to save, and loads and runs this Lua file to load. This Lua file then calls some functions which set up the data structure I wanted to save. (AddWaypoint and AddConnection, in this case.)

This is an example of how the data file may look.

Thanks! Will look into it...

Thanks man for making this Widget that I previously suggested.

Hmm

Code: Select all

  local fname = "craig_maps/" .. Game.mapName .. ".lua"
  local f,err = io.open(fname, "w")

When I try this I always get the error no matter if I create the directory and the file?

Code: Select all

       local game = Game.modShortName
       local fname = "building-templates/" .. game .. ".lua"
       local f,err = io.open(fname, "w")

only widgets can use the io-lib (gadgets still have read access via vfs)

Another example, using table.save: http://spring1944.svn.sourceforge.net/v ... iew=markup

I always get the error

Which error?

Cool, didn't even know there was a table.save

I always get the error

Which error?

Cannot find directory or file.

This worked...

Although I thought the starting directory is already LuaUI\Widgets\!

Thanks!
