[Mod] Teleporter Mod [1.07] [teleporter]

Hi, announcing the teleporter mod. The mod is on github.

The teleporter mod adds teleporter pads to minetest. The pads allow players to teleport around a minetest world in a controllable manner.

mt1.gameboom.net port 30000 makes extensive use of teleporters: it has a teleportation network. Check it out if you want to see these in action. (Go to 0,0,0 if you are near the spawn.)

Version 1.07
Version 1.06

Creating a teleporter pad
A teleporter pad can be crafted using the following recipe:
Image
The recipe uses copper ingots and a gold block from moreores, a power plant from mesecons, and a glass block. If you don't have moreores and mesecons, this recipe works too:
Image
Once a teleporter pad has been made, it can be placed and configured much like a wall sign.

Configuring a teleporter pad
To configure a teleporter pad, right click on the pad and then enter destination coordinates. You can enter a description after the coordinates as well. The coordinates are entered as text in the following format: X,Y,Z,Description. X,Y,Z are the coordinates of the destination.
Image

Using a teleporter pad
In order to use a teleporter, just step on it. If it is properly configured and enabled, you will teleport to the destination.

Configuration options
The teleporter mod has a few options that can be used to restrict the use of teleporters. These options are specified as settings (variables) in config.lua. The options are as follows:

  • teleport_perms_to_build
    When true, a player has to have the teleport permission to build a teleporter. When false, anyone can build a new teleporter.
  • teleport_perms_to_configure
    When true, a player has to have the teleport permission to configure a teleporter. Players can still build teleporters without this, however the teleporter will be locked to the default location.
  • teleport_requires_pairing
    When true, a teleporter can only be configured to teleport to a location near an existing teleporter. This prevents players from pointing teleporters in to unexplored terrain.
  • teleport_pairing_check_radius
    Specifies the size of the volume to scan when looking for a paired teleporter. Do not set this to a large value; the number of nodes scanned increases by a power of 3.
  • teleport_default_coordinates
    Allows for the default coordinates for new a teleporter to be specified. This is useful when players can build new teleporters, but can't configure them.

Can you release a version that doesn't require the privs stuff? I need to test something, but the code here is too long :P

Try to stick to 16x16 textures. :P
Also, use vanilla items in the recipes... not everyone wants to install mesecons and moreores to have this mod.

Ok Calinou, 16x16 texture and default item recipe added.

I don't get how you go about teleporting someone when they are standing on the teleporter pad - what is your ''secret''? (lol)

Nothing secret or hidden in the mod. Take a look at the source code; the code that accomplishes this is neatly contained within the abm. (minetest.register_abm( ... ). Try going through it line-by-line, and understanding what each line does. Remember that the teleporter coordinates are stored in the node metadata.

I have already done that, but I will try again later...

Version 1.07 released. Contains only minor updates: config options were moved in to config.lua.

I fixed up your teleporter a little bit. Things I changed:

added teleporter to creative inventory
allowing destination of default x,y,z
disabled redundant owner message for server
mod tells player where the destination and teleporter are at
mod keeps player off of destination telepad, fixing a very bad glitch

Download the whole thing or replace teleporter/init.lua with this code:

Configuration options
The teleporter mod has a few options that can be used to restrict the use of teleporters. These options are specified as settings (variables) in config.lua. The options are as follows


do you need to configure anything to actually just use the teleporters?

Can you modify it adding name for coordinates? Such as here http://minetest.net/forum/viewtopic.php?id=2321
It's more simple to remember a name than three numbers...

I have a strange bug with this mod. Sometimes after a teleport I see myself at the same place, but the real coordinates are changed. When I try to go somewhere, I die because in my real (not seen) position I have already teleported and go to a wall or lava.

It can be crafted with mese blocks if you use the latest minetest_game.

What is the center block in the second recipe? The other blocks I have been able to identify as wood and glass. The middle one I am not sure of. Of course, I do use texture packs a lot so that's probably why I cannot identify it...

Help would be appreciated! Thanks.

It should be mese. I think the texture in the game changed for a little while back when I wrote the mod.

Thanks for your quick response! Yes, it was Mese. I built the teleporter pad with no problem, but then ran into a problem when I went to set the coordinates. I rightclicked on it, and a grey box showed up, but there was no text entry box. Then it kicked me out of the world and back to the main menu.

Here is what debug.txt says about the incident:
14:11:55: ERROR[main]: ServerError: /home/byron/.minetest/mods/teleporter/init.lua:159: bad argument #1 to 'match' (string expected, got nil)

I tried it a few more times, and each time the same thing happened. What do I have to do to fix this?

It sounds like something has changed in minetest and the teleporter mod needs to updated. It has been a few years since I've played minetest. I'll look in to it more and update the mod it this evening.

Thank you, I would really appreciate it. This mod sounds really interesting and it would be great if we could get it to work with the latest Minetest. :-)
