== Some basic LUA code to log digiline messages and steer a jumpdrive with a touchscreen ==
 +

<syntaxhighlight lang="lua">

--[[
 +
Basic Pandorabox tools
 +
 +
BUG:
 +
- When a numerical value is contained in event.msg the LUAc run will fail! Resolve by checking for type "table" before probing keys!
 +
- Current coordinates in LUAc doesn't reset when a jump was requested but not executed (e.g. obstructed, Refresh+Reset fixes the state)
 +
TODO:
 +
- Refreshing the touchscreen repaints the formspec fully. Make use of replacing GUI elements!
 +
- Add page for channels and other settings
 +
- Changing the radius does not adjust instant_jump distance (This may result in jump into itself)
 +
- Changing instant_jump distance too small is actually set to the smallest possible but late for the GUI to always show that
 +
- Unify usage of linebuffer
 +
- Hardcoded textarea name "display" (cut in logging to prevent logging itself inflating string size) prevents more than one such textarea per page

<syntaxhighlight lang="lua">

 +
Usage:
 +
- Mount the game controller (Rightclick it)
 +
- Set direction of travel (Look that way)
 +
- Increase jump distance (Hold the jump key and slightly move your mouse [or pushing the forward key])
 +
- Jump (Release the jump button)
 +
Setup:
 +
LUAc with this code attached to:
 +
- Jumpdrive (jumpdrive:engine), digiline channel "jumpdrive" (default)
 +
- Digilines Game Controller (digistuff:controller), digiline channel "gc"
 +
Optional (for feedback):
 +
- Digilines Noteblock (digistuff:noteblock), digiline channel "speaker"
 +

(See the settings to e.g. change the channels)

 +
Jump on ;)

Hiho Pandorabox o/


I love this place for the large variety of functional modifications like technic, mesecon, pipeworks, digiline and modifications extending those.

I also value the transparency of this server due to this wiki and its contents like the mod list.

The maintenance you pull off is awesome!


Thank you for this great place ;)

Some basic LUA code to log digiline messages and steer a jumpdrive with a touchscreen

--[[
Basic Pandorabox tools

BUG:
- When a numerical value is contained in event.msg the LUAc run will fail! Resolve by checking for type "table" before probing keys!
- Current coordinates in LUAc doesn't reset when a jump was requested but not executed (e.g. obstructed, Refresh+Reset fixes the state)
TODO:
- Refreshing the touchscreen repaints the formspec fully. Make use of replacing GUI elements!
- Add page for channels and other settings
- Changing the radius does not adjust instant_jump distance (This may result in jump into itself)
- Changing instant_jump distance too small is actually set to the smallest possible but late for the GUI to always show that
- Unify usage of linebuffer
- Hardcoded textarea name "display" (cut in logging to prevent logging itself inflating string size) prevents more than one such textarea per page

Game Controller steered Jumpdrive with Noteblock feedback

--[[
Usage:
- Mount the game controller (Rightclick it)
- Set direction of travel (Look that way)
- Increase jump distance (Hold the jump key and slightly move your mouse [or pushing the forward key])
- Jump (Release the jump button)
Setup:
LUAc with this code attached to:
- Jumpdrive (jumpdrive:engine), digiline channel "jumpdrive" (default)
- Digilines Game Controller (digistuff:controller), digiline channel "gc"
Optional (for feedback):
- Digilines Noteblock (digistuff:noteblock), digiline channel "speaker"

(See the settings to e.g. change the channels)

Jump on ;)
