Why does it create same name twice instead of two different names in the lists?

Have I create my first Object Orient programming Basic? I just been learning from BlitzMax_OOP_Tutorial as I seem to get hang of it. |

-something wrong (IMHO)Boss = New Player Boss.id = 1 Boss.name = "David R" Boss.skill_level=77 Boss.id = 2 Boss.name = "Paul C" Boss.skill_level=17 here you're creating 1 object boss. then you assign a value to each field twice. it's the same doing a=2 a=4 -the player list can be embedded into the object here my solution (there's some code optimization to do but it works) Strict

| @HotShot2005, johnnyfreak is probably right but, unfortunately, there are so many oddities and errors in your code I am guessing you wrote it without really knowing why you were doing things. Is that right? If so, I would suggest you check out : Beginners Guide to Bmax and Learning Object-Oriented Programming in Blitzmax |

| I dont think I have fully learn Object-Oriented Programming in Blitzmax very well and I guess I have keep learning those both tutorial until I fully understand what is what. |

Local Boss:Player Boss = New Player Boss.id = 1 Boss.name = "David R" Boss.skill_level=77 Boss.id = 2 Boss.name = "Paul C" Boss.skill_level=17 This is like saying, Local apples:Int apples = 5 apples = 7 You do not have 2 seperate bosses, you have one boss. The last paragraph of code overwrites the original data. 'Put the address of this new Boss into variable Player NewBoss = New Player Don't know if this is a typo but you got Boss and Player the wrong way round in the description. |
