[Feedback] There are something still miss in lesson 1

[vuongkkk]

First: Reference variable
Since i'm a coder, i still remember when i learn about variable: i must learn what is reference var and what is storage var.

globals
integer a
integer b
endglobals
function SetBValue takes integer i returns nothing
     set a=i
     set b=a
     set i=i+1
endfunction

In some program languages, a is storage var, b is reference var.
And if the storage var (a) changes, the reference var (b) changes too.
However, in jass, both a and b is storage var! Then rewrite a with the other integer does not change b

And what about i?
Simple test:

function TestSetValue takes nothing returns nothing
    local integer test=1
    call SetBValue(test)
    call BJDebug(I2S(test))
endfunction

The integer displays it's 1.
So the basic law here is:
- JASS have no reference variable.
Althought it's very simple, we still need to know that! Because it's basic and it has utmost influence!

Second: How to convert a variable to another type?
Like Nes said, there are native types and non-native types

the list of primitives would include
boolean
integer
real
code
handle
string

I2R	I2S	R2I	R2S	S2I	S2R
2 -> 2.0	3 -> "3"	2.8 -> 2	2.1 -> "2.100"	"3.12345" -> 3	"5.123456" -> 5.123

And something is more interesting:

function TestEvaluate takes nothing returns nothing
    local integer test=SetBValue
    call BJDebug(I2S(test))
    set test=abcfunc
    call BJDebug(I2S(test))
endfunction

Result is:
1
0

And advance knowledge with the types extends native type:
Ex:
native function GetHandleId takes handle h returns integer
can use like this
call GetHandleId(TriggerUnit)

vuongkk, I wrote that map, lol... not mag

The only thing mag did was put it up in a post

You start getting into conversions and what not in week #2

Retrieving values in functions is too much for week #1.

In week #1, what's important is understanding variables, understanding memory, and understanding how to call functions as well as the difference between functions and natives.

It's way*** too early to be introducing the topics you mentioned for week #1

 

[vuongkkk]

Ahh, because the title : Variable .... =.=!
Make sure don't miss even the smallest thing...
I'm observer, good work, you guys

 

[Nestharus]

But the title isn't variable, that was mag's blunder calling it variables, lol


the variables portion of the map only introduce variables


also, I don't think that references and values ever need to be covered, heh

values are introduced very well at the start, and you also start to get a feeling for pointers, which become much more important later on when you start doing structs ^)^

lol, it was actually wrote in one book that total newb who never worked with programming before would think that if I set b to a, b will change when I change a.
You doesnt sound like a newb, you aound like a experienced programmer
Jass is too simple and there are no pointers or references in Jass afaik
nes, tho I think conversations could be included in week 1 because its week between each of them
its like in our school, for every little thing(1D arrays and 2D arrays split to two weeks) we have 2 hours, but we only have 2 of them in one week which is sad

 

[Nestharus]

in week #3, that stuff should be pretty apparent : )

week #3 = creating functions

heck, even in week #2, that should become pretty apparent

 

[vuongkkk]

Actually, if i don't test, i will misunderstand in case variable i.
At least, add the First: Reference variable like advance in any week which you think it's suitable.
I subscribed jass class and i'm going to follow you to the end
