[WIP] Time Travel (name subject to change) [time_travel]

[slemon]

Ah yes but for Time Travelling nodes isn't necessary all this work... Minetest has a built-in function:
"minetest.rollback_revert_actions_by" so we can back on time... I already tested but I don't implemented yet because I need a efficient way to save the player position...
also it's possible backup the "map.sqlite" file "manually" (reading bytes and writing on other file... and then switch them)
But thanks for your suggestion!

Well if you are going to use rollback, you won't to be able to play in different times simultaneously (in multiplayer)

[iangp]

hmmmm probably...
I was thinking in play in only one world line (of multiples) at a determined point in time, and not multiple players in multiple points in time at once.
There's a little issue with that: Players can talk with any other players in a different "time" on chat XD
my priority is follow the logical (also some limitations) of the anime Steins; Gate...
Perhaps, I can incorporate other theories of time traveling further that could use your suggestion...
You make me curious about how would be a game like that hehe different times simultaneously...

[slemon]

different times simultaneously...

It might also be possible to add multiple time lines and play them at the same time. HAHAHAHA

[iangp]

UPDATE:
Bug when pausing the video was fixed now
I've implemented a 4 Bytes hash /(*o*)/
just a simple one but it worked pretty well...
Theres "no way" (yet) to pause the sound at a determined point...

Thank you for report,
can you give me more informations?
That happens on the first run?
Because here on my Notebook still working...
Did you get the latest version?

EDIT: Try erase these files from your world folder (they are created by my mod and they can be outdated):
world_line.txt
timetravel_phone_database.txt
timetravel_video_galery.txt
Note that any message that you have sent previously (w that mod) will be erased.
EDIT2: I have emulated that problem deleting only when I delete the *database*.txt...
Now I'm working in a fix...
EDIT3: I know what is going on here,
It's because on_join function goes first than the load the database (That are wrong hihi)

[iangp]

@mahmutelmas06 I think that is now fixed... thank you again for report the bug!

[mahmutelmas06]

Nice to see that you have released fix but still i have the error.
I have created a new world.
I have activated only your mod.
When i start the game after loading nodeboxes game crashes before begin.
I use the latest build by stfan5

[iangp]

I also... but i already make it work
so please try redownload now...

Is the mod working now?

[mahmutelmas06]

Now it starts well.
I didnt try all functions but game starts.

[iangp]

:D good!
Thanks a lot again...
Well try open the main screen of the phone...
And if you get some blank things in the video galery it's just because I don't upload these textures because aren't my *property and I just used for tests...

[mahmutelmas06]

I dont know if this is a bug but when i rightclick to micravawe...

and kicks me out of the game

[Rui]

[DELETED]

[iangp]

@mahmutelmas06 as Rui said this is "normal" hehehehe I'm working to do something better...
When you are kicked out, the numbers on display changes, I've search how to update these numbers... I think I should see the code of signs (the mod, not the default) that shows characters and change them in-game, without this "ugly hack"
@rui
OH This shows a reconnect option!!!! LOL I missed that.

Thank you both.

[iangp]

UPD8:
I saw the code of "signs[2]" and applied the same... I use partially nodeboxes and partially entities.
The result: Now we can update the display on real time...
I'm really excited for start to code the time travel...but first things first...

You could make every object dropped into the microwave green, just execute their settexturemod to colorize it green and maybe add a mask (idk what mask does exactly)
https://github.com/minetest/minetest/bl ... .txt#L2573
https://github.com/minetest/minetest/bl ... i.txt#L352

[iangp]

I was searching for it and nothing returned yet...
[and that "settexturemod(mod)", what is this "mod" in the argument?]
It's a nice idea... but when I pick up the item, probably, I will get the original item, with the original color again...
and I wanna eat gelnanas also XD !

Off: interests: a green base64 image

[Hybrid Dog]

https://github.com/HybridDog/nuke/blob/ ... #L538-L542
the nuke mod uses settexturemod

Maybe could also copy parts (no on_step, on_punch, etc.) of the entity's definition (and the changed properties of the object) and give them to a dummy entity.

A green base64 image:

Mod is modifier (a filter), now I understand, thanks.

I'm thinking on another idea (a fork of yours):
The microwave drop the gel-thing (with the color changed as you have suggested) and I change the item that are returned when you punch this item:
A dummy gelatinous item (Something like that: You see the gelatinous item with your original form but when you touch it the item turns into slime)

------------------------------
xsel -o cool, a new command for me, it's get what is selected !
base64 -d (decode) > (a pipe) img.png (output file)
I used the built-in support on the web browser XD your way it's more cool
The result looks like a slime :D

[Hybrid Dog]

btw: ppm images can be written by hand, e.g.

Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.

Code: Select all

P3
1
1
255
1 255 1

This is a fairly green 1x1 picture.
If you simulate compressing (to make them green) ppm images, you could change red to red%64, green to 192+green%64 and blue to blue%64, the rest (P3, resx, resy and colour_count) is kept.
