I'm very sorry if this question has been answered many times , but is it possible have and Procedure inside a structure

Example :

Code: Select all

SmallStruct\SayHello("Hello")

Thanks in Advance

No, I don't think that's possible. Search the forum for OOP to get some ideas on how to do object oriented things in PB.

Thanks Karbon,

After doing a search on the forums I found that a BIG discussion had taken place about OOP back in June.

The reason for this question is because I am currently trying to design and develop a small 2d game engine to help me to prevent writing the same non-specific game code over and over again.

I thought that maybe having my procedure attached to my structure would make my engine seem a little bit more organized.

Such as :

Code: Select all

2DEngine\Intit2DFunctions()
2DEngine\DrawAllSprites()

Yeah, even having classes in structures would be quite helpfull. But there will be no OOP in this version of the basic dialect, is there?

Yes their is

Search for the Clock example ... on the forum. It creates a class.

As you will have seen in that big discussion, something like this should work, even though it's a bit more awkward.

Code: Select all

Structure foo
    my_proc.l
EndStructure

Procedure bleh()
    Debug "hell, world"
EndProcedure

DefType.foo bar
bar\my_proc = @bleh()
CallFunctionFast(bar\my_proc)

Newcoder,

The interface function introduced in version 3.8 does the job for you.

Interfaces are used by Microsoft's COM standard for creating Components that can be accessed by any language.

With version 3.8 we can do the same in Purebasic, though it is still early days.

It's still awkward, and I haven't got a good example yet.

Take a look at this post for my work in progress:

I hope to have a tutorial prepared soon.
