Description : This code snippet I made allows you to switch between data easily. GREAT for beginners who get sick of using Dims ( ) or many Global variables!

Code :

Code: BlitzBasic

1. Type player
2.  
3.         Field name$
4.         Field age
5.         Field sex$
6.  
7. End Type
8.  
9. info.player = Initiate_Type ( )
10.  
11. ; Create a new pointer variable of type player
12. info.player = MyFunction( info.player, "Bill", 36, "Male" )
13.  
14.         Locate 0, 0
15.  
16.                 Print info
17. ame$ + " - " + infoage
18.                 Print
19.                 Print "Sex: "+infosex$
20.  
21.                 Print
22.  
23.                 Print "Press any key..."
24.  
25.         WaitKey
26.  
27.         Cls
28.  
29. info.player = MyFunction( info.player, "Rachel", 21, "Female" )
30.  
31.         Locate 0, 0
32.  
33.                 Print info
34. ame$ + " - " + infoage
35.                 Print
36.                 Print "Sex: "+infosex$
37.                
38.                 Print
39.                
40.                 Print "Press any key to quit..."
41.  
42.         WaitKey
43.  
44.         Cls
45.  
46. End
47.  
48. ; store the returned pointer in it.
49. ; Note that the 'player' and 'player' pointer variables now both point to the same ~
50. ; custom type object.
51.  
52. Function MyFunction.player( info.player, name$, age%, sex$ )
53.  
54.         info
55. ame$ = name$
56.         infoage% = age%
57.         infosex$ = sex$
58.  
59.         Return info
60.  
61. End Function
62.  
63. Function Initiate_Type.player ( )
64.  
65.         info.player = New player ; Create a new 'player' custom type object.
66.        
67.         Return info
68.  
69. End Function

 Thanks for this tutorial.I think it may have finally made the use of pointers stick in my brain. It had previously escaped me for some reason.I'll try this method from now on.

 Glad you could find some use with it! Pointers always got to me too. They still do! But they're MUCH easier now thanks to a little research & this function!

 I'll really need to study this one more closely, looks like may help to wrap my head round it.

 Wow! I'm so glad to see this helping alot of people! I hope you can make use of it all!

 hey Guy.What would make this easier to understand would be the use of a non similar type name.Instead of using player.player use player.infoThat might clear it up even more by using something that reads exactly as to what is going on in there.
