We’re still on summer “break”, but there has been a few evenings time to work on some TODO items, lately especially on the TextEdit implementation. It’s still far from complete (the basic, single-style TextEdit – Styled TextEdit is another undertaking on its own!), but there has been some progress that has already some visible effects.
For example, one of the games we’ve been testing emulation with, Scarab of RA, relies EXTREMELY lot on TextEdit, including quest log, inventory (which includes selecting items with text selection highlight included), help/hint, about, and score dialogs. Some of these work in very interesting ways, for example quest log and inventory assemble text by concatenating text from individual segments – for example, “16 ounces of food” line in inventory is assembled one by one from strings “16”, ” “, “ounce”, “s”, ” of food”, and carriage return. The game also appears to use the internal line start offsets to intercept clicks in inventory, highlighting individual lines using text selection by itself.
The game is already approaching playable state, but there are still a few issues – most notably, recalibration of line start offsets does not update last line offsets correctly when removing, causing removed lines to sometimes leave “trashed” text at end of text edit boxes. Here’s some screenshots of how it looks like now:
Additionally, a few other games (Lemmings, Simcity) can now proceed past copy protection screens, as we can finally use the VERY hacky TEKey implementation to enter correct answers to the protection questions (SimCity also required a bunch of new selectors to be added to the FP68K SANE dispatcher):
EDIT: Here’s a video of first 15 minutes of Mac Lemmings gameplay:
There is also some effect on productivity apps:
As the “message” window in HyperCard 1.x is now able to accept commands, we can use “set userlevel to 5” command to actually modify the included stacks! Still a lot of things broken there, but yet a lot new functionality unlocked… We haven’t though had time to play with them, but it should soon be much more usable!
EDIT: After minor tweaking with SDL TextInput API, MacPascal can also now accept text input, compile and run Pascal code:
In general, TextEdit still has a lot of important features unfinished or to be implemented:
- No caret display yet (teCaret in TEDoText)
- TEClick not yet implemented, thus using mouse for selecting text does not work yet
- TEKey is VERY hacky, needs for example arrow key control, backspace support, etc
- Dialog Manager keyboard input does not yet handle default items/clipboard commands etc
- The keyboard driver is still passing key events through scancodes without real mapping to actual MacRoman characters, preventing modifiers/host operating system keyboard layout from having effect
- Line start recalibration has still sometimes issue when removing lines from middle of text
- Selections have still some visual glitches, especially when typing text in dialogs
- Styled TextEdit support still completely missing…for now
- Probably other things too which I can’t remember…
And now back to the summer break…
