[etoys-dev] References in textual scripts

[Bert Freudenberg]

Huh? The reference pool is stored in the published project - why would we lose anything? The mechanism is there we just need to hook it up.

I typically make a textual script first, throw in tiles from all the objects I need to use, then switch to textual mode and start editing. Another way is to make a new throw-away script and drop some tile from the object you want to reference in, then switch it to textual mode. That will reveal its player's reference name.
