Define new keys with mod?

[mrf]

Howdy,

Is it possible to define a new key mapping using a mod? A specific example: I would like to add a self-destruct key to the game. When the key is pressed, my character dies immediately. I don't want this functionality attached to any thing in the world and I do want it globally available to all players. I would also like a key mapping that reduces health each time it is pressed. (This could be a preferred alternative to the instantaneous self-destruct key.)

Not generally. There's exactly one key which isn't used by the engine and typically isn't used by tools/mods. It's the "use/aux1" key, usually mapped to 'E' on the keyboard. You'd also have to poll for whether the key is currently depressed or not, because there are no events delivered.

OK, well that's sort of a relief. I've added 9 new keys to the game already, defining 10 different speeds. Those were easy since they were just extensions to the forward key. Adding the self-destruct key has been difficult and the whole time I've been experimenting I've had this nagging feeling I should be using a mod for it but I never saw anything in the modding API that made it look possible.
Then this afternoon I was hoping I could use a mod for it since that would have to be easier than what I'm doing.

I remember reading some discussions about custom mappable keys... (but cannot remember where)

Something already asked here: https://github.com/minetest/minetest/issues/560

Just asking...
Why not just register a new chat command to do this for you. Set it with a priv so it can be granted.
If you really need it bound to a single key there are many apps out there for key bindings (are they still called macros?). Mayhaps I am not understanding what you are trying to accomplish.
