Socoder -> Blitz Max -> Wave's tutorial questions
Fri, 11 Jun 2010, 09:15
lijap	I am back with more nooby questions! I was reading wave's tutorial to get started in blitzmax and I got lost in the eachin loops and types, can anyone try to help my stubborn mind understand? All help is much appreciated. If you find any links that could be helpful please include them.

Mog	Link to said tutorials? As for EachIn / Types, it's a little tricky. Imagine a type as a collection of variables that go into a list (Linked List) that can be iterated through for whatever means. Say you have an enemy. Usually Enemies comprise of multiple variables that you would either: a) use a variable for each parameter - Enemy1health, Enemy2health, Enemy1Name... - Blah! It's a bad idea, since they're 'hard coded'. b) have a series of arrays for enemy parameter - EnemyHealth[ID], EnemyName[ID] Types are the best of both worlds. Like trying to make enemies above, it fits the bill for such an application because you can do this: Type TEnemy Field Health:Int Field Name:String End Type Enemy:TEnemy=New TEnemy Enemy.Health=100 Enemy.Name="Whatever" --v Notice how i called New TEnemy? That makes a new enemy object, with a collection of variables for you to use. If you call it again, you'll have another - which makes 2. But how do you recall this information? Through the usage of lists. EnemyList:TList=CreateList() Type TEnemy Field Health:Int Field Name:String End Type Enemy:TEnemy=New TEnemy Enemy.Health=100 Enemy.Name="Number One" ListAddLast Enemylist,Enemy Enemy:TEnemy=New TEnemy Enemy.Health=200 Enemy.Name="Numero Dos" ListAddLast Enemylist,Enemy --v This puts both objects into the list called 'Enemylist', which you can then iterate through using... EachIn! For Enemy:TEnemy=EachIn EnemyList Print Enemy.Name Next --v Since I added two objects above, it will print: Number One Numero Dos --v There's a few other nuances, but this is the usage of the two.

Mog	Yes, pretty much. Imagine a variable as a sheet of paper, while a type would be something of a book that you can create and delete on a whim. -=-=- I am Busy Mongoose - My Website Dev PC: AMD 8150-FX, 16gb Ram, GeForce GTX 680 2gb Current Project: Pyroxene
