Re: New project Prince of Persia (open source available)

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.

Re: New project Prince of Persia (open source available)

The fun never ends Smiley Happy

I decided to start adding support for mods (custom level sets, sprites and sounds) in my implementation, there are several mods created by the community:
Full List: http://www.popot.org/custom_levels.php?mod=0000042
Example of a mod I'm using for test: http://www.popot.org/custom_levels.php?mod=0000042

This way anyone could use a level editor like Apoplexy http://www.norbertdejonge.nl/apoplexy/ to expand the game.
This tool can generate standard XML files - http://www.popot.org/documentation.php? ... XML_Format - that are now supported by the game.

I also revamped the menu screens and added a new configuration screen to select the Mod and configure some Cheat Modes, checkout some screen shots:

Re: New project Prince of Persia (open source available)

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.

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)
