How to refer to object data ingame

Hello,
I wanted to know if its possible to refer to any object data ingame,
like from any spell the 'data1' field, or something like that.

I need to read only, because I want to get the description.

No.

EDIT: there are a couple things you can get like abilities effect fields or something but you cannot get any tooltips, cooldowns, etc..

There was an slk thing, can you explain what that does?

As far as I know, it can't be done apart from some spell art fields like projectile art (which more spellmakers should utilize) etc.

But I can load slks in vJASS, can't I?

I think Reinventing the Craft is doing some in-depth R+D into this subject, with things like Dynamic Tooltips.

I'll post a jasshelper extention in a bit that I'm that autoloads fields you want from object data into a struct, so you can refer to it ingame.

Sounds awesome.
It will also work for no-widgetized maps ?

Yes because it loads the data when you save the map

That is EXACTLY what I meant. Hah, seems like I know more as you, Fledermaus xD
