[Mod] Mesecons (= redstone) [GitHub] [minetest-mod-mesecons]

[Jeija]

I will upload a video of a giant self-building bridge soon. It has 3 floors: One for cars, one for trains and one for pedestrians. Just have to wait for my classmate to render the vid. It is possible using this mod and the nyanland mod.

[IPushButton2653]

I'm making a room that the floor dissappears when you walk on it

[Jeija]

That should not be too difficult. Just use an object detector and a Mesecon network under the removestone floor.
Btw, I love this idea, Basto:

object detectors on top of sings should only activate if player, which name is on the sign, is near to the detector

[IPushButton2653]

If I can make it work, it will be awesome

[sfan5]

Just commited Wall Buttons!

[Jeija]

Amazing!! Good job!

[sfan5]

Just fixed the Rotating-Switch-Bug! :)
It was param1 not param2.

[Jordach]

@Jordach: That sounds really interesting. If you like I would be willing to help with that. I've always wanted to try my hand at something more than an adder :).

yup I'm learning from mc vids.

[Jeija]

NIce sfan5, thx for fixing. I once tried param1 myself, but it didn't work back then :( Maybe I made a small mistake or so. NIce to know that btw.
I guess, sfan5, you should make different mesecon rules for buttons. Just put them in the get_rules function (I will maybe add a add_rules function when I have more time). Just look at the mesecon torch code for this.

Ok, I'll make a different Mesecon-Rule for buttons.

[hijera]

what's about and/or/not/xor blocks? It's possible to make logical structures using invertor, but it become so bulky then

[Jeija]

Some changes on github, check them out.
e.g. object detectors above signs indicate the player name on the sign and new mesecon button rules. Also splitted files (I'll continue doing that, so commiting will be easier)
@Sfan5: How do I delete the README~ file? I have no idea...

@hijera: These blocks would be possible, but I can't do them myself (simply don't have time). If you or someone else wants to do that, just commit it.

"git rm README~" should work

[Jeija]

didnt work. gonna retry tomorow and post the error if still not working

[sfan5]

My Commits disappeared. I can't see them under Commits! :O

[Baŝto]

Jeija: Am I allowed to use your code for a mod/fix?

I'll try to rebuild corefunctions from scratch.
My targets for this project:

• flipflops and oscillator should be impossible (instead special nodes for that: blinky plant and a d-flipflop consisting of 3 blocks)
• electricity flows from input to output
• circuit without abm

I'll use inputs/outputs and 'virtual' input/outputs (forks, inverters ...)
Every 'input'-node knows all 'output'-nodes, which state is dependant on that node. (maximum of 6)
Every node know the flow-directions of each side: comes/goes/none.
the calculation of the flowdirection could take a while, have to use accumulators to avoid oscillators.
(only finds the next 'input' the rest of the circuit is not important)
The flow of electricity needs only the 'i/o'-nodes ... the rest is just 'decoration'.

In big circuits it'll never happen that the whole circuit must be recalculated!

And I would call the inverters esem-blocks (mese reversed)


… and don't wait for that, could take a while.

[Temperest]

For the adder: Make sure that the whole machine is in a close radius, like 30 blocks away. Unfortunately, if mesecon circuits are farer away, minetest doesn't simulate them.
@Temperest: Looks awesome! I can add you to git if you give me your name... Else, just post it here.

Is there anything that can be done about the 30 block limitation? I ran into this too when I put a flashing light on top of a tall tower.

Oh, my username at GitHub is Uberi.

And, as promised, the updated code:

Still could not get timers to work :/. This version does without it. Remember not to connect plugs to inverters directly, or MineTest may crash.

Will look into it.

[Jeija]

@Sfan5: I guess that happened because i had to --force the upload (I forgot to pull and didn't want to push). Well, I'm just new to git...
@Basto: yep, just use it
@Temperest: I added you on git, please commit your code.

If any code can make the server crash, please disable it using a setting variable please!
(Like it already is with Temperest's awesome commit. It says TEMPEREST_ENABLE=0 in init.lua)
Please also use Tabs for syntax and not spaces if possible.

Is there anything that can be done about the 30 block limitation? I ran into this too when I put a flashing light on top of a tall tower.

Any c++ dev know this?

That not the Sense of Git

[Jeija]

I know and I found out later, but as I said I just don't know much about it. In fact, your code is in the patch, I just cloned to another directory. I hope this won't happen again.
I added you, Basto.

[sfan5]

Made a Wiki Page with all Blocks:
https://github.com/Jeija/minetest-mod-mesecons/wiki/Blocks

[sfan5]

I'm working on an API to add Lightstone.
Current State:

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

mesecon:lightstone_add(name, base_item, texture_off, texture_on)

This Function creates the Block, the Crafting Recipe and the Functionatility of the Block
Example:
mesecon:lightstone_add("red", "craft default:clay_brick 1", "jeija_lightstone_red_off.png", "jeija_lightstone_red_on.png")
Crafting Recipe will be:

The Orange Fields represent BaseItem, in the Example Cooked Clay

Nice!

Btw: Pistons shouldn't push air

Help Pls! :)

I really like to use this mod but i can't install it... :( I tried to copy it to the specified folder but i cant see any changes in the game. I tried with Linux version (installed) and windows version as well. What could be the problem? I using the latest version of minetest..
Thx

[Calinou]

First of all you will have to download the latest 0.4 snapshot, or use the git if you know how to:
https://github.com/downloads/celeron55/minetest/minetest-0.4.dev-20120106-1-win32.zip
The git version provides no binaries for both Windows and Linux, you will have to compile it yourself (check the downloads page)

Then you will have to install the mods:
On Linux, if you are compiling without run_in_place parameter: /home/"username"/.minetest/ - then create a folder named "usermods" there, then drop the "jeija" folder inside.
On Linux, if you are compiling with run_in_place parameter: /home/"username"/"minetest's-installation-folder"/ - then create a folder named "usermods" there, then drop the "jeija" folder inside.

Note: you cannot play on 0.3 servers with a 0.4 client.

[sycam]

i like mods to be in zip because my minetest dosen't like tar

[sapier]

i don't think minetest likes zip either ... but I could be wrong I didn't test this. I think you'll have to extract both.

sorry i recently found out that tar is a Linux file ind i'm using windows 7
