Virtual touch joystick 🕹

12" C64 tablet with a pencil. Awesome 😎.

BTW, I've started to work on VirtualC64 4.0 a couple of days ago. In v4.0, I want to port back a lot of stuff from vAmiga, so both emulator will eventually be closer together, both internally (code base) and externally (GUI).

nice !! That looks cool 🤤 🤤 🤤 🤤 ... is it fas enough ?

here I tried the brand new virtual joystick on desktop with the mouse ... flys ok

@jeromeetienne has a super cool feature called mouse emulation ... the joystick takes mouse events as touch events... yeah !!

should be ok for vC64web as it has only a handful of modifications in the core code to make it run with wasm ... I am looking forward to copy the new emulator core into vC64web when you are done with it... then afterwards it should be easy to do the vAmigaWeb right?

does the touch joystick work with the pencil ?

Hmm, it doesn't load any more on the iPad 🤭. It says "Emscripten - Downloading...", but doesn't finish. It loads well in Chrome or Safari.

[mithrendal]

I had this too 🥴. Go to ipados settings ... choose safari...

scroll down the last item “extended” ... then choose “website data” then type in the search field dirk and then delete the website data by swiping to left

This only deletes website files not the snapshots in the indexeddb nor the settings in localstorage.

I have to dig into the PWA thing again I think...

[dirkwhoffmann]

Deleting the cached data did the trick, it loads fine now 😎. But I wasn't successful with the game.

I wasn't able to load T64 files on the iPad. When I select a T64 file on the iPad (from the Documents folder like I did with the Roms), nothing happens. Typing "Run" has no effect, too.

CRTs work, but I wasn't able to move PacMan with the new joystick. When I use the pen in the left screen area, I get two white circles, but when I use the pen in the right area, I get red circles. In both cases, PacMan doesn't hear on my commands. Furthermore, using the pen causes the game to freeze from time to time 😲. And there is no sound on the iPad 🙁.

For enable sound you have to demute the ipad and touch into the emulator canvas. That enables sound. (We should have an overlay icon for it I guess ✌️)

The virtual joystick are effective two. When you touch with the finger in the left half of the screen then this gives the directions ... it shows it with white circles. When you touch the right side ... that tells vc64 the fire 🔥 press ... this is drawn with a red circle

As the two virtual joystick instances handle effectively multitouch the mouse has problems with it ... it seems to draw direction and fire at the same position and time.

For pacman game try the other port should work. When this does not work reset to blue c64 screen and put touch to port1 and move it ... it should print strange numbers 2221.... and so on, no?

Tape files is still an open issue. I did not connected it to the core yet.

Do you see freezes with fingers only too?

I have to fly another round FortApo...

I got the freezes too now. When enabling the touch joystick... 🙈

Strange the last 5 times or so it worked so well...

I got it ... it is an JavaScript exception

Look... half transparent

[mithrendal]

found it 😅

the first problem was a copy paste error 🙄 ... that made "port2 touch" selectable ... but it effectively did not create the virtual_joystick component... (only when you had before selected port1 and then directly switched to port2 then it was working)

found the second problem 😬... this was a null pointer exception and kind of interrupted/freezed the allmighty "draw_one_frame_into_SDL". The problem was that the drop down box selected the touch but the joystick was not created (due to first problem) hence it stopped

both are fixed and pushed to gh-pages ...

you see it that it is the new version when you straight go to select port2 to touch and when it then draws circles ... and does not freeze then it is the fixed version

is PacMan in port2 ?

this time again iOS did not update (well known issue on the net for iOS) ... but then I used the "manually update installation" button in the vc64web settings ... and it worked ... had not to clear the cache ... anyway .. we have to keep an eye on that one 🧐

[dirkwhoffmann]

PacMan works. Woohoo 🥳. Now I know what tablets are made for 😎.

For enable sound you have to demute the iPad

How do I demute the iPad? 🙄

[mithrendal]

what is it for an iPad ? Does it have a hardware mute switch like an iPhone ? Or software mute only ? Did you ramp up the volume ?

what about the pencil does it work now ? Maybe cool for GEOS 😁!

[mithrendal]

look we got a tiny favicon now ... do you see it ? Its very small...

other news ... I prepared a trap for bugs ... when an exception occurs it will be displayed as an alert .. with line number and source file name ... it is also appended to the live debug output even if that was disabled ... so enabling it should make one see all the trapped bugs ...👻 👻 👻
