HELP ME u.u

Post by Hacker » Thu Oct 18, 2012 3:22 pm

Hello :)

Hello :) I have some doubts about coolbasic ... Could you please help me?

I do not see much use of "arrays" and "classes" because I read the manual coolbasic but I speak Spanish :(. Could someone post a source code where
can explain this?

The other problem I have is that I try to create functions. But when I use the command "include" and try to compile I get an error that says "can't open include file ...." and I can not use functions :( help me please.

thank you very much for your help!

There are no classes in CB.

You declare an array with the keyword Dim. An array is always global.

Code: Select all

Dim array(10)
would make an array with 11 cells (0 to 10). The array type is Integer as default.

Code: Select all

Dim array(10) As String
would make a String array.

To make a function you use the syntax: Function fName(param1, param2, ...) [Function code here] End Function

Code: Select all

Function HelloWorld()
    Print "Hello World"
EndFunction
To return from a function you use the command "Return [returnValue]". You cannot use just "return", but must always return a value. Edit: but you don't actually need a return-command if you don't want to return a value. A function can return all basic data type values, so there are no specific return types for ints, floats etc.

A parameter for a function can be only a primitive data type. For example, you can't put an array as a parameter (this will most likely change in the upcoming coolbasic, at least I truly hope so). The same goes for returning a value.

To include a file you simply use the command 'Include "filepath"'. If the compiler complains, most likely the path is incorrect. With unsaved code the path root (for relative paths) is the Coolbasic-folder. For saved files and exes the root is where the source or exe is. The include command only includes a separate .cb-source file, and it's of course really useful, but not mandatory. You can write all your code to a single file if you want.

While there are no classes in cb, somewhat comparable are Types. Types are custom data structures and are always stored in linked lists. You can use types like this:

Code: Select all

//Create collection named "MyFirstType" containing 2 fields (or properties)
Type MyFirstType
    Field someNumber
    Field someString As String
End Type

//Create new instance of MyFirstType (note: variable_name.type_name notation is used to declare variable as a type member)
a.MyFirstType = New(MyFirstType)
//Accessing type fields via backslash (\)
a\someNumber = 5
a\someString = "Hello "

b.MyFirstType = New(MyFirstType)
b\someNumber = 9
b\someString = "World"

//Iterate over all type members:
For i.MyFirstType = Each MyFirstType
    //Calculate sum of all someNumbers
    counter = counter + i\someNumber
    //Output someString
    Write i\someString
Next i
Print "" //Start a new line
Print "Sum: " + i\someNumber

WaitKey
Types cannot contain functions (methods) and doesn't support typical oo-programming like inheritance. Members of one type are always contained in same list which can be iterated over For Each loop, or using First(Type), Last(Type), After(TypeMember) and Before(TypeMember) commands. Delete(TypeMember) deletes type member.

Hi Nattakiha, and welcome to CoolBasic Forums!

Could you elaborate on what you mean by "Want to contact this topic to do."? Your message is quite unclear.
