arrays issue: objects lose data

Monkey Forums/Monkey Programming/arrays issue: objects lose data

Raul	(Posted 2013) [#1]

hello all,

recently I restarted learning Monkey and I have a small issue:

this is my code:

For Local x:Int = 0 To numberOfHo - 1
     myHo[numberOfHo] = New cHO
     myHo[x].fName = "object " + x
Next 	           	           	
           	      
For Local x:Int = 0 To numberOfHo - 1										
     Print myHo[x].fName
     Print x
Next

I assumed myHO[0] will have the name="object 0"; myHO[1] will have the name "object 1" and so on..

the problem is that all the myHO have name = "object 49" (numberOfHo = 50)

at every loop all the objects change the name to the last one.. :|

where is my mistake?

numberOfHo is fixed -- you're declaring myHo [numberOfHo] over and over -- use myHo [x].

myHo[numberOfHo] = New cHO
''shouldbe
myHo[x] = New cHO

remember that "x" in your For-Next loop is the iterator value, whereas numberOfHo remains constant.

yes there is a mistake, but the issue is still present:
here it is the new code, i removed numberOfHo to be sure..

For Local x:Int = 0 To 10
	myHo[x] = New cHO
	myHo[x].fName = "obiect " + x
Next 	           	           	
           	      
For Local x:Int = 0 To 10									
     Print x
     Print myHo[x].fName				
Next

BUT I STILL GET same name name for all the objects...

I cant belive this.

Here is the code:

For Local x:Int = 0 To 10
	myHo[x] = New cHO
	myHo[x].fName = "obiect " + x
	Print "New X: " + myHo[x].fName
	If x > 0 Print "Precedend X: " + myHo[x - 1].fName	
Next

and here is the result:

Your code in the first of the two previous posts should work too.

One issue I have sometimes seen is that when you are testing in HTML5 the browser sometimes reloads the old program if MServer is still running. Maybe that happened. If I fix a bug and the fix seems to do nothing, that's the first thing I check!

tested with XNA, same result.

also i tried this:

   myHo[0] = New cHO()
   myHo[1] = New cHO()
           	
   myHo[0].fName = "nume 0"
   myHo[1].fName = "nume 1"
           	
   For Local x:Int = 0 To 1
        Print myHo[x].fName				
   Next

prints me:
nume 1
nume 1

How do you declare your array ?
Something like global myHo:cHO[11] ?

Raul	(Posted 2013) [#9]

i am inside my Scene class:

Field myHo:cHO[] = New cHO[100]

i think you have fName as Global when it should be a field.

what does your class look like.

Raul	(Posted 2013) [#11]

yes! that was it..

now it is ok. noob me :|
