From 7e00678df69df968ccf235d46190702bdc59e9ad Mon Sep 17 00:00:00 2001 From: cheapie Date: Sat, 2 May 2020 23:58:34 -0500 Subject: Add digilines game controller This node allows players to have their keypresses forwarded to a LuaC, instead of moving the player around. This is intended to be used for making LuaC-based games. --- README | 10 ++ controller.lua | 238 ++++++++++++++++++++++++++++++++ init.lua | 1 + textures/digistuff_controller_sides.png | Bin 0 -> 1942 bytes textures/digistuff_controller_top.png | Bin 0 -> 2056 bytes 5 files changed, 249 insertions(+) create mode 100644 controller.lua create mode 100644 textures/digistuff_controller_sides.png create mode 100644 textures/digistuff_controller_top.png diff --git a/README b/README index d04d661..37baa7f 100644 --- a/README +++ b/README @@ -80,3 +80,13 @@ To write a card, send a command in the following format: After sending the write command, swipe the card to be written and the reader will send back the following message: {event = "write"} Both blank and previously written cards can be written to.
