1. Place a mese block
2. Add a bobblock next to it
3. Let the bob block, then the mese block, get a mesecons signal

How far do the lasers go?

[12Me21]

Cool, there should be a laser detector

[rubenwardy]

Nice!

[lonely]

It can't load and run bobblocks, even if i rename it!

[rubenwardy]

Cool, there should be a laser detector

What should it do?

Enable a mesecons wire.

You can use minetest.get_modpath(modname) to check to see if mesecons is installed.

thanks


New version:
— vertical lasers added
— textures rotated
— more colours (except white, actually this isn't a colour) added

yes, and there should be mirrors, too

bobblocks has depends, too

I won't add mirrors without reflections and they aren't possible yet. Maybe I'll add a laser detector.

All a mirror would need to do is when a laser beam hits it, send another laser beam at a 90 degree angle.

Great ! Looking forward to the laser detector, if possible, make entities (especially players) don't let the laser go through them, but that may be hard
By the way you should add mesecons to depends in your post since it now needs mesecons power.

I could do it but it would cause big lags and it wouldn't work in the right time.

good idea.

Only checking for players wouldn't be that laggy on small servers or singleplayer if you use a globalstep.
EDIT: maybe update the laser with an abm so when you dig in front of it you don't have to restart the mesecons signal

1. Place a mese block
2. Add a bobblock (red or yellow) next to it
3. Let the mese block get mesecons energy

At first my laser was flammable (yes, the tree burned down):


The wool was flammable so you'll not see this again:



The nodebox looks like the shot particles of wz2100:



I changed this texture later to 1xh:



This is not my bug! It's from bobblocks!:


I didn't know that there are 2 caves...:



Here 2 lasers are crossing:





Vertical lasers added:

+100 on a scale of 1 to 10

Nice mod.

[Inocudom]

The laser detector will make both this mod and mesecons more fun to play with.

[Aqua]

Epic mod! Keep up the great work with your mods!
+1

[arsdragonfly]

Can you add mirrors to change its route?

[aron1263]

I cant open it it says" failed to load and run \minetest-0.4.7\bin\..\mods\laser_master\init.lua

If it isn't a modpack you'll need to rename it. In this case from laser_master to laser.

A check is looking in the init.lua, for example:
minetest.register_node("laser:detector", {

[Bas080]

+1 This is really cool. For long distances i will use the lasers instead of mesecons.
+1 And they look pretty as decoration.
+1 When i'm far from home i just have to look for lasers pointing up.

Why can't lasers cross path? I understand that that would mean much more nodes as you have to make a crossed laser section for every color crossing with another color. Why not make it work with the similar colored lasers? Or you could make a very bright shining light node and place that in the laser intersections and let the lasers continue.

Anyways, +3, i like this mod!

[Bas080]

Actually you can only see the lasers because of the fog in minetest...

I don't understand.

Some less wanted features:

• Lasers should continue when node that interrupted the laser is removed.
• If interrupting node is a bobblock it removes the similar color laser completely!
• And what if you have two different colors lasers pointing towards each other?

I am trying to fix some of these unwanted features

i tried renaming it laser but it says there is a error

It's possible you didn't enable the (most up to date) dependencies:
- Jeija's mesecons: https://forum.minetest.net/viewtopic.php?pid=4785#p4785
- RabbiBob's bobblocks: https://forum.minetest.net/viewtopic.php?id=1274

Else you"ll need to paste the ERROR here in a post to help you.

Exit minetest. Delete the debug.txt file. Start minetest, start the game with lasers in it. End the game and exit minetest. Open debug.txt. Copy the all the ERROR lines and paste them here.

[Hybrid Dog]

New version:
— voxel manipulation is used → faster
— minetest.after is used, too → the signal is sent before the laser is shown
— nodes are allowed to define functions which get executed if a laser touches them or disappears next to them
— adding mirrors should be possible now

[Krock]

Good work!
Gonna download this mod.

[Inocudom]

Very good to see you still working on this mod.

Hello,

I'm novice to minetest. I have tested your mods but i have this error.
"G:\Minetest\minetest-0.4.9\bin\..\mods\laser\init.lua:186: attempt to call method 'get_param2_data' (a nil value)"

1. Place a mese block
2. Add a bobblock next to it
3. Let the bob block, then the mese block, get mesecons energy

Can you explain part 3, what's " mesecons energy " ? I can't find it in mesecon objects , what's it's name exactly. I have put a switch and when i put it on, i have this error.

This is a screenshot of my structure .

With "mesecons energy" I mean just a mesecons signal.
I think if the error message appears, the laser would be created.
It looks like this mod requires the newest minetest (0.4.9-dev).
I think here you can download the newest version for windows and for linux you can get it here (ubuntu/mint) and here (Arch linux)
Sorry, I didn't knew that and didn't look for it and so I didn't mention it yet.

[balthazariv]

Hello,

My minetest version is 0.4.9 for windows.
I'm novice in minetest and you have many mesecon objects. I'm not sure for switch for mesecon signal.
My structure with 1 ) "mese block", 2 ) "bobblock" and 3) switch for mesecon signal is correct or no ?

Thanks

here's an example of a structure which should create a "laser"

to use this mod you need minetest 0.4.9-dev, I think.
