I try to visualize it and learn by mx2 codes.
And found this text about a array with struct

 
<div class=”post-text”>

struct

An array of values v encoded by a struct (value type) looks like this in memory:

vvvv

class

An array of values v encoded by a class (reference type) look like this:

pppp

..v..v…v.v..

where p are the this pointers, or references, which point to the actual values v on the heap. The dots indicate other objects that may be interspersed on the heap. In the case of reference types you need to reference v via the corresponding p, in the case of value types you can get the value directly via its offset in the array.

</div>

I don’t see it yet haha, I know the point about a reference and non reference.

So a struct don’t cost memory because it will reset after a loop, and will use only memory when it is used by me inside a loop ?

While a Class Field is used from the beginning till the end of the program.

 

Look at this not working example

Normally I want to keep a postion X and Y and update this every loop.
Is it better/faster to keep it in a struct.

 

Monkey

Class MojoTest Extends Window Field posX:Float ' it cost memory now Method OnRender( canvas:Canvas ) Override App.RequestRender() ' posX is still using memory ' lot of code here Local blaX:Float ' decl. is using memory Local inst:=New TheStruct ' (decl.) only at this point a struct is using memory inst.posX=MOUSEX() blaX=MOUSEX() ' only at this point a Local is using memory (same as struct) posX=MOUSEX() ' reference to the memory and update the value End Struct TheStruct Field posX:Float End End

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26

Class MojoTest Extends Window   Field posX:Float ' it cost memory now   Method OnRender( canvas:Canvas ) Override   App.RequestRender()   ' posX is still using memory ' lot of code here   Local blaX:Float ' decl. is using memory   Local inst:=New TheStruct ' (decl.) only at this point a struct is using memory inst.posX=MOUSEX() blaX=MOUSEX() ' only at this point a Local is using memory (same as struct)   posX=MOUSEX() ' reference to the memory and update the value   End     Struct TheStruct Field posX:Float End End

Can I say, A Struct acts just a Local but you can store Fields inside them.
It is only using memory when you declare them, and it is resetting after a loop.

If you want to use a variable in multiple classes then maybe you can make a global struct.
And maybe the struct will use memory if a function is using the global struct, but mostly not.

[gcmartijnParticipant]

Would be cool if someone explain the need about structs.
When do you need them and are the a lot faster then a class ?

With my background using C# and python,monkey1,javascript,nodejs I never needed them.

http://monkey2.monkey-x.com/language-reference/

To declare a struct:

Struct Identifier

Monkey

[crayon-5cb9e31dda02d771909902 inline="true" ] ...Struct members...

1	[crayon-5cb9e31dda02d771909902 inline="true" ]    ...Struct members...

[/crayon]

End

A struct can contain consts, globals, fields, methods, functions and other user defined types.

Structs are similar to classes, but differ in several important ways:

• A struct is a ‘value type’, whereas a class is a ‘reference type’. This means that when you assign a struct to a variable, pass a struct to a function or return a struct from a function, the entire struct is copied in the process.     —– what does this mean ?
• Stucts are statically typed, whereas classes are dynamically typed.
• Struct methods cannot be virtual.
• A struct cannot extend anything.

Feng shui

@amon

I total agree with you except I do need a little more then just program.
For example that correct nice font in the editor, or that background color and syntax color.

These things make it (for me) more fun to program.

But at the root level, its the idea of making (program) that thing you want.
(using a good documentation / forum with feedback)

[gcmartijnParticipant]

Example please, is it slow Device proof ?

I want to try something new, a fresh start using mx2.

But as you can see I had some trouble with getting the most important thing oke, fps.

is the way mx2 handle a render/update setframerate the same ?

[gcmartijnParticipant]

I hope that someone create (maybe mark) a good tutorial about

deltatime / framerate / oprender / update in MX2

A year ago I was using this for Monkey1 but I don’t know what now the best use is using MX2

https://github.com/Regal-Internet-Brothers/deltatime

Some tests using deltatime with huge ‘strange’ things

[gcmartijnParticipant]

I’m new at using git, and now i’m wondering what will happen with the modified files by AdamStrange.

Is he using the latest ted source using pull , and can he / access to upload/overwrite the official Ted source ?

Or will this be a source at his git only, so there are now two versions about ted ?
This would be weird because Mark is the ‘boss’ about Ted and can make fast changes.
When he make a change , then the other ted is not oke anymore.

Or will this live as a fork within the official source ?

[gcmartijnParticipant]

yep working

[gcmartijnParticipant]

* coming

I forget to say

.tree-leaf .tree-leaf-text {
/* margin-left: 8px; */
/* line-height: 2em; */
}

so its only:
.tree-leaf .tree-expando.expanded {}
.tree-leaf .tree-leaf-text {}
.tree-leaf .tree-expando {
color: #9B4DCA;
cursor: pointer;
float: left;
}

[gcmartijnParticipant]

Ah I see now, I had many files inside a directory and din’t see that there was already a monkey2 (very old one)

now its working oke.

I see that TED2 is not alive anymore in this release, you can’t do everything once

Done.

 

no still the same problem.

I thought everyone uses a release, found here:

https://github.com/blitz-research/monkey2/releases

 

Going to download this now

https://github.com/blitz-research/monkey2/archive/master.zip

maybe its better to delete that release version to keep only one download link.

[gcmartijnParticipant]

Its readable and fresh keep it for now
