Hi. I would like to use EToys for a project but I'm having a hard time adding my own actions. I suspect that I am missing something obvious, and would appreciate any pointers you could offer. I've tried to RTFM, but I can't find the FM so I'm kind of stuck.
So... As a test case, I decided that I would make some simple methods to animate the opacity of a Morph. I also wanted to add an instance variable and manipulate it.
So I created a subclass of Morph and, on the class side, added:
additionsToViewerCategories
^ #( (#seg ( (slot grink 'grink is a nonsense variable' String
readWrite Player getGrink Player setGrink:) (command changeOpacityLevel: 'change the opacity level' Player) )))
and I created #getGrink, #setGrink:, and #changeOpacityLevel: on the new subclass of Morph.
When I instantiate the new object and open an etoys viewer, the "seg" category is there but it is empty.
In Etoys you are scripting Players, not Morphs. The Morphs are just a costume for a Player. You need to add those methods to class Player, and forward them to its costume.
