oops i hit a bug, i wonder if i can upload a video? the kid fell off the ledge where the first spikes are (I suck at this game, but great at finding bugs!)
he’s stuck in an endless loop falling over and over…
Update: played for a while longer and that didn’t happen again. Didn’t get out of level 1 though…

I saw that happening once but was never able to reproduce again, will investigate it.

Thanks for you time testing it :slightly_smiling_face:

I started the Shadow development and committed a couple of bug fixes.

Please if you downloaded the code, let me know your impressions, and ideas.

Happened to me the first time I played, in the default mode, Couldn’t reproduce again though.

Yeah this is a tricky bug, it happens both with the prince and the guards, I will spend some time next weekend to try to force it.

65

Might just be something that happens the first time the app is run, reproduced by accident after re-installing the channel:

Here is a video of it with debug turned on, hope this helps.

edit: figured out how to repro it successfully multiple times: video with debug on.

Great Joel, it helps a lot, thanks!

I’m in Vegas for a quick vacation, if I don’t get rich winning a poker tournament I will take a look on Sunday.

67

i feel i have seen this happen in the original game, stuck in such a fall/die sequence?
so it might not be a bug in the translation but rather a “very faithful” port?

68

I fixed the “endless fall” issue, it was a wall bump happening in the exact moment of the “land”, that was moving the character into the wall.
I submitted the fix to GitHub, will be available on the Private Channel with the next beta release (v0.10)

Beta Release “The Shadow” (v0.10)

This is the second Beta release of the game, the main changes are:

  • All Shadow appearances were implemented;

  • It’s now possible to finish Level 3. The button to open room 2 was too far to reach the gate in time with the Roku control limitations;

  • A checkpoint is now in Level 3 Room 2, so if the kid dies after that point, he will revive there;

  • The Skeleton skills were too high, adjusted to the same of the original DOS game;

  • Added a visual indicator (white border) to the Shift mode, it helps a lot to avoid running into an abyss;

  • Bug fixes.

Those are very welcome and positive fixes/changes :slightly_smiling_face:

I released a new version last week and forgot to inform here!

I initially had the impression that to implement the “Flip Screen” effect would require a huge refactoring, doing it on the sprites level, but I figured out that I could just make the roCompositor to draw to a bitmap, flip it and then paint to the roScreen. That slows down the animation so I had to accelerate when the flip mode is on.

I already fixed several other bugs after this release, probably on next weekend I will release v0.12 as a “Feature Complete” RC.

Enjoy!

Beta Release “Flip Potion” (v0.11)

Release Notes

This is the third Beta release of the game, the main changes are:

  • The flip screen potion effect (Level 9) is implemented;

  • Fixes on special events for the Skeleton, Mouse and Shadow;

  • Fixes related to issues when the room has multiple slicers side by side;

  • Several other Bug fixes.

Check the full Changelog: https://github.com/lvcabral/Prince-of-P … angelog.md

While trying to test for audio problems Komag complains about, i ran into a quirk of PoP on a RokuTV.

After showing a “Warning: Your Roku device doesn’t support accelerated graphics, this game will not perform well.” dialog, the opening screen / credits don’t fill the screen but show in the upper left corner, maybe sized 2/3 (e.g. as if a 720p image was shown on 1080p screen w/no stretch). When starting a game later, things are back to normal - i.e. full screen/centered. Any idea why is that?

Never saw this before, will try on my Roku HD. It’s clear that for some reason the screen is not changing to the 854x480 mode.

I had no idea such resolution is possible even.
I’ll take a guess behavior differs between the OpenGL and non-OGL (24xx, 25xx, 27xx, Express 37xx, Roku TV 5xxx) players.

You can see different roScreen resolutions here:

I could reproduce it on my sister’s Roku 2 (old generation), will create a fix for it. I also noticed some issues with the music, that I can’t reproduce in my low end Roku HD.
The OpenGL devices are really the best alternative for games.

Oh yes, OGL for the win!
I suspect the schism is between the OGL and DirectFB camps of players. Roku has a common abstraction (roScreen/r2d2) on top of both of these but as it can be expected, sometimes it “leaks”.

Btw, i suggest avoid using player names: “Roku 2” name have been (ab)used for at least 3 way different hardwares - 30xx/31xx, 2720 and 4210. I’ll take a stab hers being a 2720 (no OGL)
