Prince Of Persia.net written in C#

[David]

So could you install MonoDevelop and MonoGame?
At what part are you stuck?
Did you try to compile your game?

[polipo]

yes, i have installed a virtual machine with Ubuntu 10.04.4
after i have installed monodevelop 4.0 and added the Monogame template

Now i could compile it!!!!!

On my virtual machine the PoP.net it's very slow, but i think is a problem on my virtual machine

If you try look on my official repository you can found the linux project and the compiled version!

PS
remenber the linux project NOT CONTAINS the Content file it can be BUILD only by windows..

[David]

Right.
Currently I don't have access to a Linux computer, so I can't test it now.

[polipo]

If someone can test on real linux environment
can send me some feedback ? thanks

[Norbert]

Is compilation under Linux really necessary?
I wrote on August 2nd:

polipo, can you provide a download link for just the program, without the ClickOnce or classic MSI setup?

It was my understanding that Mono should be able to run the program that also runs on Windows.
Then again, maybe .NET isn't portable enough, since it was never meant to work on Linux.

[polipo]

Dear Norber,
i know your idea about .NET but you are wrong.
Mono can compile in varius platform win, linux, android, ios ecc , .NET is portable!

Monogame project haven't realeased yet the possibilty to compile the "Content Project"
actually is the only Linux limitation about porting a monogame prj on Linux environment.

>> "Is compilation under Linux really necessary?" No, if someone already compiled it.

I have already compiled for linux Ubuntu Lucid and Windows, follow this step:
1) https://princeofpersia.codeplex.com/

2) Go in Download and look OTHER Release you can found the binary Windows or Linux

Yes, I can run that under Linux.
Unfortunately, in-game, it only has one frame every 9 (or so) seconds, so it's too slow to play the game.

[polipo]

Thanks Norbert,
i will check as soon, wait from me some news.

[salvadorc17]

Yes, I can run that under Linux.
Unfortunately, in-game, it only has one frame every 9 (or so) seconds, so it's too slow to play the game.

That hapenned to me too, what i should have to do to make project run faster is to change the monogame to xna, but that will not work with linux...

[Norbert]

xna, but that will not work with linux...

Are you sure?
Several games at http://en.wikipedia.org/wiki/Microsoft_ ... at_use_XNA are available for Linux.
(Like Bastion and Fez, I own both on Steam.)
Although maybe those games only use XNA under Windows, I dunno.

[polipo]

Hi to all
First question:

"..change monogame to xna..." for windows is possible BUT is not a solution, with the recent monogame 3.2 it runs perfectly on Windows.
if there are some slow frame on win, please send me some test to do (windows version ecc ecc)
i will investigate if is a PoP engine problem or monogame engine problem.
(remenber XNA is abandoned project from Microsoft ;-()

"...slow frame rate on linux.." it's a mistery i havent a "real" linux machine and effectively is slow, i can have time to install a real
ubuntu for test it.

My test on Android with monogame it runs perfectly the only problem is a slow LOADING content files.

Question :
Have Someone tested PoP.net on WINE / Linux?

Bye

[David]

I could start the game on Linux (with Mono).

I don't have the problem that Norbert has, but there are other problems:

- If I start PrinceOfPersia.exe from the file manager, the game closes itself when I press a key to start level 1.
This does not happen if I start it from the command line.

- Loading level 1 takes 15 seconds.
- When the loading ends, I get some errors on the console: (repeated 5 times)

Code: Select all

ERROR:Content.Load<dContentRes>System.Collections.Generic.KeyNotFoundException: The given key was not present in the dictionary.
  at System.Collections.Generic.Dictionary`2[System.String,System.Object].get_Item (System.String key) [0x00000] in <filename unknown>:0 
  at PrinceOfPersia.Sequence.Initialize (Microsoft.Xna.Framework.Content.ContentManager Content) [0x00000] in <filename unknown>:0 CONFIG_sprite_kidKid_166

But level 1 starts despite those errors.
- There is some unreadable black text at the top of the screen.
According to your screenshots they should be white.
- The game's window is bigger than the room.
Sometimes both right and down, sometimes only down.

- The game crashes when the kid lands after a standing jump.
I get this error: (it is written twice on the console)

Code: Select all

- Safe step does works only with the left shift key.
- The cheats don't work if the kid died.
So I can't restart the level.
- The ". = give sword to kid" does not seem to work at all.
It works, but I have to press numpad 5 to draw the sword.
- The kid attacks with the sword only if I press left or right together with shift.
- I can't hurt the guard.
- Can't put the sword away.
- If I press numpad 2/4/6/8 too long, their actions are done twice.
It's possible to move into a wall room, but I can't move out from there. Then the only thing I can do is to restart the level.
- Can't climb up to a different room.
- Can't drink potions.
- Potions have white bubbles.
- The kid does not die if he falls into spikes.
- Can't pick up the sword.
- Can't climb up to a gate that is currently closing.
If kid is already at the gate, he falls down.
- Gates close even if kid is standing on their open button.
- Close buttons are replaced with open buttons.
- The level ends when kid touches the exit door.
- Guards can walk on air. (See the first guard on level 2.)
- Top half of big pillars is replaced with floor.
- Can't step to edge, kid steps *off* the edge instead.
- All guards are blue.
- Gates that should be initially open are closed. (See level 2.)
- Level 3: at the bottom of the first room there are wall pieces.
In the same room, kid appears *in front of* some pillars.
This also happens in the room with the exit door.
- There are no chompers or skeletons.
- Can't go near closed gates from left. (See level 4.)
- Doortops and arches are replaced with floors.
- Loose floors don't press buttons.
- Guards can't press buttons.

Although maybe those games only use XNA under Windows, I dunno.

I think those exceptions was converted to different platform using monogame or something else, but xna is made for windows, and xbox 360...

So many bugs David have found, i think some of them are just little mistake, but also hope custom events will added, " like a potion opens the door"
