Topic: iGlobalStringStringSet/Get better then scripts linked together? (Read 1325 times)

I think the title says it all. Do I save performance by using iGlobalStringSet/Get instead of linking scripts together?

It's in this situation: I got a fps addon (homemade) and I'm working on a zombie addon. In the fps addon, a script reads the players location. The zombie addon needs to know the player location too. So I can either link the zombie script to the fps addons rigidbody sphere, or use iGlobalStringSet to magically send the location to the zombie script.

Another advance of using iGlobalStringSet, when I put some of the addons together, I don't need to link much to anything. Everything work by itself!

But let's get back to the question.

Thank you. Stupid of me. Should have seen it.
One more question, is there an easier way to send away a vector then creating 3 strings?
And how to send a quaternion?

Mike Hense · « **Reply #3 on:** August 25, 2011, 08:50:34 AM »

assemble the string on the sender side putting a space at the end of each element... send the vector over as a single string "0 0 0"... and parse the string on the receiver side for the spaces separating each element...

Okay, but how to take out all the elements of the string?

Mike Hense · « **Reply #5 on:** August 25, 2011, 11:56:56 AM »

here's a simple example...

Quote

Vector3 playerLoc;
string strX,strY,strZ;

int playerChar =OBJ_22;
int textObj =OBJ_44;

void Main(){

// get the player location a vector3
iObjectLocation(playerChar,playerLoc);

// get the component parts x.y.z
// and convert each to a string
iStringStr(strX,playerLoc.x,"%4.3f");
iStringStr(strY,playerLoc.x,"%4.3f");
iStringStr(strZ,playerLoc.x,"%4.3f");

// concat the strings into one big
// string, adding a * char as a separator
iObjectTextSet(textObj,strX + "*" + strY + "*" + strZ);

}

that's how you pack em in... you should be able to figure out how to get em out...

(more coming)

Thanks, but the problem is that I don't know how to get them out.

... do ya see the more coming at the end???

i understood your question... wait one...

I'm sorry. I'm childlike impatient.

And I love it!

Mike Hense · « **Reply #9 on:** August 25, 2011, 12:54:10 PM »

oh... heres the full logic (more or less)...

this should show how to do everything...

Code: [Select]

Vector3        playerLoc;
string         strX,strY,strZ, bigString, retString, retStrX, retStrY, retStrZ;
string         retBigString;

int            playerChar     =OBJ_22;
int            textObj        =OBJ_44;
int            textObj2       =OBJ_66;

int            firstSeparator, secondSeparator, end;

void Main(){
 
   //                  get the player location a vector3   
   iObjectLocation(playerChar,playerLoc);
    
   //                   get the component parts x.y.z
   //                   and make em into a string
   iStringStr(strX,playerLoc.x,"%4.3f");
   iStringStr(strY,playerLoc.y,"%4.3f");
   iStringStr(strZ,playerLoc.z,"%4.3f");

   //                   concat the strings into one big
   //                   string, adding a * char as a separator
   bigString=strX + "*" + strY + "*" + strZ ;  
   //                   store it in globalString space 11
   iGlobalStringSet(bigString+"#",10);  
   //                   show it on screen                
   iObjectTextSet(textObj,"");iObjectTextSet(textObj,bigString);


   //                   now to unpack em

   iGlobalStringGet(retString,10);

   //                   find first *
   firstSeparator=iStringFind(retString,"*",0,true);

   //                   find second *
   secondSeparator=iStringFind(retString,"*",firstSeparator+1,true);  
   //                   find last *
   end=iStringFind(retString,"#",0,true);

   //                   now we know where the vectors break up
   //                   so we can retrieve the 3 strings 
   iStringLeft(retStrX,retString,firstSeparator-1);
   iStringMid(retStrY,retString,firstSeparator+1,secondSeparator);
   iStringMid(retStrZ,retString,secondSeparator+1,end);


   retBigString=retStrX +"*" +  retStrY +"*" + retStrZ  ;
   iObjectTextSet(textObj2,""); iObjectTextSet(textObj2,retBigString);  
   
   //                   test a number
   OUT_88=iStringVal(retStrX);
    
}

good luck...

Thanks. But I think it's easier to just send all of the vector elements in their own string.
Do you know if costs extra performance every time you can another iGlobalStringSet/Get?

RobertooMolvadoo · « **Reply #11 on:** August 25, 2011, 12:59:17 PM »

And how to send a Quaternion?

well... that's your choice... i took the time to show you how to do it, now you say it's easier to do it string by string... now you ask about quaternions...

sorry Roberto... i'm not wasting any more time showing you a solution when you're only gonna turn around and say "Thanks. But I think it's easier to just send all of the quaternion elements over in their own string"...

do it the easy way if you want... (one whole string space for single element... what a waste... i mean, it's not like global string space is an unlimited resource)...

anyways... you'll find out...

good luck...

Basically the same way. Just use euler angles.

Also, it doesn't have to be a huge long complicated script. Once you understand it, then you can rewrite it in your own way. Make it as simple as you want.

I don't know if cramming info into one string will save on performance, because isn't it the same amount of information being stored either way?
