Get Spell Name without 2da

For my dispeling script I wanted to provide feedback to players as to wich spell was being targeted, and the first option was to use
wich shouldn't be used too heavily... sadly as offered it can only be used inside a loop for my needs, and spells.2da is almost 0.6mb size
My second option was to "cache" the 2da file and relevant info (Label, or spell name) inside the local data of an object, this would require heavy read / SetLocalString (839 times), but only once at module load
Result :
Then to remove the "_" characters you can use notepad++ and ctrl+f / replace tab "_" to " " (space)
Final result
string Get2DAString(string s2DA, string sColumn, int nRow)wich shouldn't be used too heavily... sadly as offered it can only be used inside a loop for my needs, and spells.2da is almost 0.6mb size
My second option was to "cache" the 2da file and relevant info (Label, or spell name) inside the local data of an object, this would require heavy read / SetLocalString (839 times), but only once at module load
void SetupSpellsNameByID()
{
object oHolder = GetObjectByTag("_SPELLS_ID_2DA_");
int i = 0; int n= 839;
for(i; i<=n; i++)
{
SetLocalString(oHolder, IntToString(i), Get2DAString("spells", "Label", i));
}
}
and this was still bad, so the last option, and best, was to log all spells inside a basic function, but to build that function with 839 lines was a daunting task, instead of going by hand I wrote a script that will generate the function itself, write it inside the Logs, and then I would just copy paste it to use inside the toolset.void LogBuildFunctionGetSpellName()
{
string s = "\n"+"string GetSpellName(int i)"+"\n";
s+= "{"+"\n";
s+= "string s;"+"\n";
s+= "switch(i)"+"\n";
s+= "{"+"\n";
int i = 0; int n= 839;
for(i; i<=n; i++)
{
s+= "case "+IntToString(i)+" : s = \""+Get2DAString("spells", "Label", i)+"\"; break;"+"\n";
}
s+= "}"+"\n"; // end switch
s+= "return s;"+"\n";
s+= "}"+"\n";// end whole function
WriteTimestampedLogEntry(s);
}
Result :
string GetSpellName(int i)
{
string s;
switch(i)
{
case 0 : s = "Acid_Fog"; break;
case 1 : s = "Aid"; break;
case 2 : s = "Animate_Dead"; break;
case 3 : s = "Barkskin"; break;
case 4 : s = "Bestow_Curse"; break;
case 5 : s = "Blade_Barrier"; break;
case 6 : s = "Bless"; break;
case 7 : s = "Bless_Weapon"; break;
case 8 : s = "Blindness_and_Deafness"; break;
case 9 : s = "Bulls_Strength"; break;
case 10 : s = "Burning_Hands"; break;
case 11 : s = "Call_Lightning"; break;
case 12 : s = "Calm_Emotions"; break;
case 13 : s = "Cats_Grace"; break;
...
case 833 : s = "PLAYER_TOOL_04"; break;
case 834 : s = "PLAYER_TOOL_05"; break;
case 835 : s = "PLAYER_TOOL_06"; break;
case 836 : s = "PLAYER_TOOL_07"; break;
case 837 : s = "PLAYER_TOOL_08"; break;
case 838 : s = "PLAYER_TOOL_09"; break;
case 839 : s = "PLAYER_TOOL_10"; break;
}
return s;
}
Then to remove the "_" characters you can use notepad++ and ctrl+f / replace tab "_" to " " (space)

(nwnlexcion : "Get2daString() now is cached the first time it is called, into the memory of the computer. Basically - you can now use this function in a loop with a lot less noticeable loss of speed!")
was tricked by the toolset's description :
// Gets a value from a 2DA file on the server and returns it as a string
// avoid using this function in loops
// - s2DA: the name of the 2da file, 16 chars max
// - sColumn: the name of the column in the 2da
// - nRow: the row in the 2da
// * returns an empty string if file, row, or column not found
thanks
This in turn makes your script caching slower, causing all your scripts to be slower. It is possible this optimization had a net negative result on the performance of your module.
This is a stretch, as these kinds of things are totally negligible in terms of perf, but illustrates the point of "premature optimization is the root of all evil". Always profile before (and after) optimizing.
