I try to put a global variable inside a IF function, the program not read it...but if i put outside the IF, it show sth...What is going on..

+ Code Snippet

DIM STARTPOINT(10)
DIM ENDPOINT(10)

STARTPOINT(1)= 2
   IF STARTPOINT(I)=2
      `POSITION OBJECT 1, RND(WIDTH#)-WIDTH#/2, 10,(RND(40)+DEPTH#/2+25)
   ENDPOINT(1)=4
ENDIF
PRINT "",STARTPOINT(1)
PRINT "",ENDPOINT(1)

WAIT KEY

Thanks for your helps...

Uhm... your snippet reads STARTPOINT(I) (capital i); I'm pretty sure that you want to put a 1 (one) there instead (if I is not declared as a variable somewhere earlier in your code, it will be regarded as having the default value of zero, hence returning STARTPOINT(0) which haven't been set and thus, that too will have a value of zero).

-> Oh, come on...

Just gotta add, while the scope is global if it's at the top of the program... (or should be), it doesn't work like that. I've run into issues myself so make sure to add "global". Also the syntax is very specific, it compiles 2 ways and only 1 way actually makes it global.

That is this way:

+ Code Snippet

global var as integer

or basically global _variablename_ as _type_

global var = N works but I have found that not to actually globalize the variable before.

Just a quirk I thought I'd add, since the topic is relevant enough

I just tried sth on my code...feel weird on it...Hope any of u can help me prove it..

when i try to code as below..what i noticed is the endpoint(1)=0.
But when i delete the "....."(dot) which locate at line "REM GO TO ......." the answer will become normal back..

Is that same on ur computer??

+ Code Snippet

DIM STARTPOINT(10)
DIM ENDPOINT(10)

   SYNC
   STARTPOINT(1)= 2
   REM --- TESTING AREA ---
   REM AT EXIT 2
   IF STARTPOINT(1)=1
      ENDPOINT(1)=1
      Y=1
   ENDIF
   IF STARTPOINT(1)=2
      `POSITION OBJECT I, RND(WIDTH#)-WIDTH#/2, 10,(RND(40)+DEPTH#/2+25)
      REM GO TO .......
      ENDPOINT(1)=2
      Y=2
   ENDIF

   PRINT "",STARTPOINT(1)
   PRINT "",ENDPOINT(1)
   PRINT "",Y

WAIT KEY

Thanks...

try Print STR$( STARTPOINT(1) ) To convert that to a string. Quotes won't be needed if you do that.

I'm unsure what you're printing exactly with that code.

So try:

+ Code Snippet

DIM STARTPOINT(10)
DIM ENDPOINT(10)

   SYNC
   STARTPOINT(1)= 2
   REM --- TESTING AREA ---
   REM AT EXIT 2
   IF STARTPOINT(1)=1
      ENDPOINT(1)=1
      Y=1
   ENDIF
   IF STARTPOINT(1)=2
      `POSITION OBJECT I, RND(WIDTH#)-WIDTH#/2, 10,(RND(40)+DEPTH#/2+25)
      REM GO TO .......
      ENDPOINT(1)=2
      Y=2
   ENDIF

   PRINT STR$(STARTPOINT(1))
   PRINT STR$(ENDPOINT(1))
   PRINT STR$(Y)
WAIT KEY

Or better yet...
since it doesn't look like you're assigning, rather just checking something... you don't need the if statements initially.

ENDPPOINT(1) = STARTPOINT(1)
Y = STARTPOINT(1)

Should take care of all possible assignments for startpoint(1).

Use FOR to assign all 10, just a suggestion.

Hmmm, I haven't used DarkAI... but I did go through some of the example programs. I don't see any waypoints, I believe you use those to go around obstacles.

Also check your Print "STARTPOINT(1): " function. PRINT is for the String type, so change the second half to + STR$(Value)

+ Code Snippet

PRINT "STARTPOINT(1): " + STR$(STARTPOINT(1))
or STR(value), forgot if it needs the $ to do it.

Also, if you "are" having a problem with DarkAI, congratulations! You can ask that question in the DarkAI section and get more help. I'm lost as to what now, but you do have the PRINT function right, that helps you debug many programs... especially 3d

I'm lost otherwise. You'll have to describe what you're trying to do, the comments only tell tiny pieces of what you're trying to do.

@feiting shadow,

Yes the $ is necessary on STR$. >_>

Other than the arrays, I see no globals defined anywhere, so I'm a little lost on what you're all talking about. And why is your entire code capitalized? 'Tis a bit hard on the thee old eyes.

Basically the problem is my entities cant reach the location tat i denote on my image.tat's somewhere near the two outlet there.but my entities only able reach the boundary of the main area,they cant go further to reach the two outlet(bus bay)
Sorry to let u feel unconvinent for ur eyes.
I belive is the problem of the boundary not the ai.
Thanks for all your kindly helps.

By the way,the startpoint(1) is a global variable.i state as dim startpoint(entities),dim endpoint(entities).oh ya..endpoint() is a global variable too,but endpointF is a function.
I just wan to print where the entities'll start and where they'll go to.
