user objects with fields and methods

[ukuru.gejacoya]

hello!

is there a way to create your own objects, for example,

Code: Select all

scene.my.object = {a=0; b="foo"; twice=(x)=>{x*2}}

and then access its fields and methods like

Code: Select all

scene.my.object.a, scene.my.object.twice(100)

etc.?

there are global objects organized like that, math.* for example.

I tried the above definition, but then if I try to access scene.my.object.a,
it throws an error:

Code: Select all

Failed to evaluate: scene.my.object.a, Object scene.my.object cannot have children; it is not a class object

as far as I understand, a ClassObject can have children, but how do I declare my own ClassObject?

There is no way to create such object, but you could use some geom for that.
Foe example make invisible box with onSpawn = (e) => {scene.my.object1 = e.this} and use it in scripts as object, just don't forget to add _ symbol to variables names for saving with scene.

[ukuru.gejacoya]

got it! spasibo!

update: it's possible to use entity instead of e.this:

Code: Select all

onSpawn = (e) => {scene.my.object1 = entity}

but then all my _local variables get stuck in the global scope after onSpawn executes, if I close the scene they are still available through console. I really can't grok thyme...

step by step example:
1. file > new scene
2. check for _foo variable in global scope: _foo -> undefined
3. create a box
4. right click it > script menu > _foo="bar" //the _foo is added
5. recheck the global scope: console > _foo -> undefined
6. enter onSpawn into the box property window: (e)=>{scene.my.box = entity} //or (e)=>{scene.my.box = e.this}, no diff
7. save the scene
8. reload the saved one
9. console > _foo -> undefined //OK
10. overwrite the scene
11. reload the scene
12. console > _foo -> bar // what's just happened? it crawls into global scope upon overwriting the scene
13. new scene
14. console > _foo -> bar // still there.

this is beyond me.

It's even worse than what you had described. After going through those steps that you outlined, I shut down Algodoo and then reopened it, and created a new blank scene. I then checked the console for _foo and it still contained "bar"! I then loaded one of my older saved scenes, and checked the global scope again. _foo was still defined and contained "bar"! It seems that no matter what I do, _foo is always defined and contains "bar"! I would say that this bug is definitely FUBAR!

Well then - forget it)

[ukuru.gejacoya]

thanks for participation, guys!

Xray, it is indeed ... Up Beyond All Recognition now you have to edit the config.cfg to get rid of it!

Kilinich, ok, trying to forget - but it seemed like a really nice way to incorporate semi-oop techniques into Algodoo

I have tried:

Scene.my.example -> {v=1;z=45;c=564};
Scene.my.v= scene.my.example.v

It gives me an error too
I think readable could work but I haven't tried yet.
