 Posted: Thu Mar 29, 2007 23:36 Post subject: Saving and Spawning Persistent Placeables |
 |
|
What I'm trying to do is save many placeables' locations into the database and then when the module loads, all of the saved placeables are spawned at each of the locations.
Can someone explain how to do this? I tried using GetPersistentLocation but it needs me to designate an object to be spawned, which should be in the database as well.
I'm sort of clueless about these NWNX functions but I have done a bit of scripting using the normal functions so I can learn quickly.
Any help is appreciated! |

This isn't something you really need the database for, unless you plan to change the locations. Could you elaborate a little more on what you are doing and why?

| I am creating a system that allows players to create their own placeables within the game world. I have a good chunk of it done but I can't figure out how to store the placeables they create persistently and then load them after a server restart. |

Hi, i can solve your problem.
Well, there is 1 thing you need to do. Create conditions to be able to create GetFirst/NextAreaInModule() function. There is two way to do it: 1) give to every area waypoint with certain tag you will then checking
2) I created these functions for letoscript, if you have letoscript in your PW i can post it to you.
Algoritm:
Player create placeable - you store on area location of placeable and resref.
In module load you get all areas by getfirst and next and then you can retrieve variables stored on area. Then you can create it.

Could you post the GetFirst/Next for letoscript please? Virusman is working on that for his events fumctions, but it'd be nice to have in the meantime.
Thanks,

Note: This is nwscripted function.
I posted it as soon I will at home.
If GetFirstArea is used first, I retrieve arealist from module.ifo and then for each area (there is resref) open .are and retrieve tag which i store to "stringlist" ("tag|tag|"). First and next function then retrieve tag from this stringlist.
Well, I now know why I didn't post it to nwvault. I shall have to translate and rework stringlist function becose I give it other name and it returns from stringlist struct.Int,.String,.Float ...

And tip:
I think is best way in OnModuleLoad event SignalEvent for each area - custom defined event for this reason, I call it OnRestart. But you should have Moneo for add all areas customdefined event.

Yes, I have the letoscript plugin, and would love to have the functions you created if you don't mind posting! 
Thanks for the help! |

No I help you willingly I like that people using my stuff (that's why I've got nwn PW).
I add my List function too, becose GetFirst/NextAreaInModule needs it. I hope you'll find it useful too!
few functions and constants from my include, name it anyhow
| Code: | #include "leto_include"
const int VARIABLE_TYPE_VARIANT = 0;
const int VARIABLE_TYPE_INT = 1;
const int VARIABLE_TYPE_FLOAT = 2;
const int VARIABLE_TYPE_STRING = 3;
const string MODULE_FILE_NAME = "GwainTharr.mod"; //don't forget to REPLACE this
struct list
{
int Int;
float Float;
string String;
string Variant;
};
//This function returns first area in module, i recommend to use it firstly at
//OnModuleLoad to initialize area string list from letoscript
//Note: Make sure you set up MODULE_FILE_NAME constant!
//Needs letoscript
object GetFirstAreaInModule();
//This function returns next area in module
//Note: Make sure you set up MODULE_FILE_NAME constant!
//Needs letoscript
object GetNextAreaInModule();
//This function will create list which is string of this formate: "3hi|3hello|"
//Also return a stringlist string you can input to ListGetFirst/NextVariable
//Note you always have got same delimiter
//nType - VARIABLE_TYPE_*
//sValue - value of your variable in string formate (so you must use IntToString etc.)
string ListCreate(int nType, string sValue, string sDelimiter="|");
//This function adds to already existing list new variable of chosen type
//Note you using same delimiter which is used in existing list
//sList - return of ListCreate
//nType - VARIABLE_TYPE_*
//sValue - value of your variable in string formate (so you must use IntToString etc.)
string ListAddVariable(string sList, int nType, string sValue, string sDelimiter="|");
//This function returns list structure from first value in inputed list.
//You should know which type of variable is there stored
//Note that if you use other type then VARIABLE_TYPE_VARIANT if add in front of
//value that indicate type, so if you have list like "hello|world|" only, use
//Variant for correct values!
//For not so skilled users use this syntax to get values:
//struct list l = ListGetFirstVariable(sList);
//string v = l.Variant;
//int n = l.Int;
//float f = l.Float;
//string s = l.String;
struct list ListGetFirstVariable(string sList, string sDelimiter="|");

WOW! Thank you so much!
However it seems that I'm missing leto_constants. I tried finding the leto download again but was unable to. Can you post leto_constants as well here? Please and thanks! |

Thanks for posting all of this but I'm still not quite sure what to do. I think you said I should store variables on the areas when the placeable is created but how do I set persistent variables on the area itself?
Sorry, this isn't making a whole lot of sense for me.  |

Well player somehow create a placeable and you want to store it. You must have nwnx_odbc plugin which contain SetPersistent functions. So then after player created placeable you store resref of placeable and position via SetPersistentString - resref and SetPersistentFloat - x,y,z position and facing on location where the PC is. e.g. SetPersistentString(GetArea(oPC),"PLACEABLE_1",resref); and so on
And then restart occur and getfirst/nextarea will needed. You get area and retrieve all variables by GetPersistent functions. From this variables you can re-create your placeable.
If you still don't understand, I can write you whole code, it isn't difficult script.

I hate to ask it, but would you mind writing it? I'm sorry but I think once I see it I'll understand how it works better.
I was trying to store the resref and location on a waypoint and then load it once the PC enters an area but I couldn't figure out a way.
Anyhoo, if you're willing to that'd be amazing. You'll be going in the credits so don't worry! |

Yes, no problem but you must wait a minute so I can tune it .
