Why these tables are empty when I check them in console?

Code: Select all

> dump(vars)
  "{\
}"
> dump(mapvars)
  "{\
}"

Do I need to initialize (override) map event every time map is loaded or it could be done once at game initialization?

Former. You Scripts/Maps/*.lua (and map events lines) will be reloaded every time the map is reloaded.
You can opt to change event directly in *.evt file, but that's a bit harder than override event in map script.

Which event should I use to initialize map event: InternalBeforeLoadMap, BeforeLoadMap, BeforeLoadMapScripts, LoadMapScripts, LoadMap, AfterLoadMap?

Neither of them. Put it directly in map script main body.

Do I need to explicitly remove event I am planning to override? Would assigning a function to it just override what was there before?

Yes. No, it would call a function after an original event has been processed.

Why these [vars,mapvars] tables are empty when I check them in console?

Because you haven't put anything into them? (default behavior)

[tnevolin]

Thank you for response.

Neither of them. Put it directly in map script main body.

I don't understand what is map script main body? I have downloaded MME2.2 and Scripts\Maps directory is empty. Should I take one of the decompiled scripts *.lua and put it there? Should I put *.txt file there as well? Do I need to modify them both?

Or I should just create custom lua script where I programmatically delete and reassign the map event?

I guess one example would worth thousands of words if you have it somewhere on a net.

I tried to remove event before reassigning the new function to it. This also deleted event hint. I would like to preserve it. Is there a way?

You mean these are user defined variables those will be stored in saves? So I can introduce any kind of variable and persist it through saves/reloads? How these examples in MME help work then???

Code: Select all

Game.MapEvtLines:RemoveEvent(60)  -- remove original event
evt.map[60] = function()
   local i
   if evt.Cmp("MapVar0", 4) then
      evt.StatusText(5)         -- "Nothing here"
   else
      evt.Add("MapVar0", 1)


I didn't understand this sentence about vars variables type. Should I declare them somehow or just put as key values in this table? What is the purpose of evt.VarNum constant? Isn't it suppose to describe existing variables in this table? Are they used somewhere in original code? Can I use them too?

Sorry. A lot of stupid questions.

Code: Select all

Variables in vars table. They can be accessed from anywhere and are stored in savegames.

First link in my signature contains probably the biggest example of MMExtension usage.
Let's look at https://gitlab.com/templayer/mmmerge/-/ ... /oute3.lua (script for map "oute3" aka New Sorpigal)
Map events 15, 16 and 231 are overridden while events 140 and 232 are extended.

Do I need to explicitly remove event I am planning to override? Would assigning a function to it just override what was there before?

Yes. No, it would call a function after an original event has been processed.

Code: Select all

Game.MapEvtLines:RemoveEvent(100)
evt.hint[100] = "hint" -- could be something like evt.str[10]
evt.map[100] = function()...

Yes, they are user defined lua variables. MapVar0 is from Map.Vars array (from MM6 itself) rather than mapvars table (from MMExtension).

vars is typical lua table. So it has typical lua key-value elements which are again typical lua variables. vars is already defined in started game (it's not defined yet in, for example, party creation). So you can put something like `vars.mytable1 = {}` or `vars.newvar75 = 12` wherever you want.

What is the purpose of evt.VarNum constant? Isn't it suppose to describe existing variables in this table? Are they used somewhere in original code? Can I use them too?

MM6/7/8 have map (and global) events coded in *.evt files. Evt file contains encoded events in binary format. Evt commands (like evt.Cmp) have their number/id. Parameters of evt commands like evt.Cmp, evt.Add, evt.Set, evt.Subtract (like "ClassIs" etc.) also have their number/id. IIRC VarNum is for these parameters. You can use number instead of string parameter name in evt command (I used it for parameter that was decoded to `nil` by MMExtension)

Very good explanation. Thank you. I think I can code these events properly now.

So you are the author of Community merge. Cool work!
You mentioned base merge branch there but I could not locate it anywhere on the net or description for it. Is community branch a de-facto standard for most users now?

[tnevolin]

Anybody knows the text color scheme? I figured out it is 2 byte value. However, I failed to understand how bits are mapped to RGB.

I'd say I'm main code contributor now.
"Base Merge" is the term for Merge itself (as Rodril made it) to better distinguish with Community Merge. I can't tell about user preference but for everyone who thinks about creating its own mode on top of Merge I would strongly recommend Community Merge master branch.

GrayFace has written once:

MM supports coloring. Just add StrColor(R,G,B) at the beginning and StrColor(0,0,0) at the end of the string. Note that the color has to be computed inside the game, as it is dependant on whether it's in 16 or 15 bits mode. StrColor function is here: https://github.com/GrayFace/MMExtension ... ctions.lua

[tnevolin]

Great pointers. Thank you.

By the way, I have a mm6 mod that emphasizes skills over items. People constantly asking me whether it can be combined with merge mod. Since you are the big contributor there feel free to have a look at it and port any features into merge or ask me to help you with that.
I know that I can also build another one on top of a merge but I don't want to multiply mods. That's useless. People need to play them. I only have created mine because I could not find any similar one out there.
