I have an object in my game which is a piece of driftwood.

I want the player to be able to refer to it as 'wood' or 'driftwood'.

I thought naming it 'driftwood' and giving it the alias 'wood' would do this. However this seems to mean that the game will only recognize 'wood'.

Go to the 'Object' tab for the item and you can add other names there.

the 'alt' (for alternative names) text box in the GUI/Editor following XanMag's guidance. You can add as many as you want, separate via the semicolon character.

You can also do the same with Verbs, using the semicolon to add more names in, as well as within a Command's 'pattern' text box

Thanks!
