Hi,
is it possible to attach a script to an ingestible which triggers when the ingestible is consumed?

Yes.

....was there...more to the question?

Yup, how can i do this exactly? When i attach the script to the ingestible i have use an On[Something], but which one triggers on consume?

None of them. You need to put a scripted Base Effect on the ingestible.

Damn, exactly that is what i dont want to do since i can not get the objectID to which the Base Effect is attached to use it later. *sigh* So i need to write a add[Something] script for each ingestible which is adding something to the players inventory instead of one script for all. :swear:

Use this for reference:

A single effect for each item is what i currently use allready, but i was looking for a possibility to use one effect for all items but it seems that its not possible at the moment.
