Using "Player" from load.lua crashes the mod on game start

I made the following simplistic load hook:
Code: Select all
local KeyBind = require "engine.KeyBind"
local Player = require "mod.class.Player"
class:bindHook("ToME:run", function(self, data)
KeyBind:load("toggle-player-ai")
game.key:addBinds {
TOGGLE_PLAYER_AI = function()
game.log("#GOLD#Player AI Toggle requested!")
game.log("#GOLD#Player AI is: %s", Player:ai_active and "#LIGHT_GREEN#enabled" or "#LIGHT_RED#disabled")
Player:player_ai_start()
end
}
end)
If I don't comment out the "require Player" line, the mod crashes between character selection and loading the first level. It gets to 100% and then just doesn't start the game. I have otherwise tested the mod and I can get the keybind to toggle a local boolean, but I'd like to have access to the Player class so I can activate a sort of "autoexplore"-like function.
The Player:ai_active boolean and the Player:player_ai_start() functions are things I added in a superload. Is that confusing the load order and trying to parse functions that don't exist yet? How can I work around that?
I can post the superload/mod/class/Player.lua too if that's relevant.

If you look in the te4_log.txt file in the same directory as your executable, you should see a detailed crash reason at the end. If none shows up/the log is incomplete, try loading ToME with the --flush-stdout argument.

Probably an error in your superload.

I found this error:
Code: Select all
Lua Error: /mod/class/Actor.lua:258: table index is nil
At [C]:-1 __newindex
At /mod/class/Actor.lua:258 init
At /mod/class/Player.lua:84 init
At /engine/class.lua:104 new
At /mod/class/Game.lua:192 newGame
At /mod/class/Game.lua:136 runReal
At /mod/class/Game.lua:93 run
At /engine/Module.lua:990 instanciate
At /engine/utils.lua:2197 showMainMenu
At /engine/init.lua:162
At [C]:-1 dofile
At /loader/init.lua:204
I then tried to add a require for Actor, which added this error (without resolving the above one):
Code: Select all
Lua Error: /mod/class/Game.lua:2206: attempt to index field 'player' (a nil value)
At [C]:-1 __index
At /mod/class/Game.lua:2206
Any idea what's going wrong?

At a guess, your require Player line in load.lua is causing Player to initialise too early.
Try moving it into the function where you need it.

Thanks! I was trying to treat "require" like "include" from C, never would have thought of putting it in a function. Now it's actually running and giving me errors when I try to run the function (function is nil), which I assume is because I didn't define it right.
It tells me that the player_ai_start function is nil, so I need to figure out how to define/call it properly. I tried calling it with Player:player_ai_start() and Player.player_ai_start() to no avail. I tried defining the function as function _M:player_ai_start() and function player_ai_start() without effect.
Disclaimer: I've never used Lua before, so help with the basic syntax may be required.
EDIT: I now know that the colon is for function declaration and it adds a self argument, so I should really be calling things with dot. This hasn't solved my problem, but it has made me less dumb.

It was an even stupider error. I forgot to add
to my init.lua file.
Issue is now resolved.
