I'm making an action RPG in Love2d, and I moved all of my player code into a separate Lua script for the sake of organization - but now upon attempting to use player.load, I get this error:
Error
main.lua:22: attempt to index global 'player' (a boolean value)
Traceback
main.lua:22: in function 'load'
[C]: in function 'xpcall'
[C]: in function 'xpcall'
this is my main.lua script:
-- RPG PROJECT IN LOVE2D
-- debug mode
debug = true -- SET FALSE BEFORE SHIPPING
-- ROOM CHART:
-- 0 - Title
-- 1 - Overworld
-- 2 - Shop
-- 3 - Boss Room
Room = 0
-- PLAYER STATE CHART:
-- 0 - free
-- 1 - attacking
-- 3 - can't move
function love.load(dt)
player = require 'Scripts/player'
player.load()
sti = require 'Libraries/sti'
gameMap = sti('Maps/overworld.lua')
menuImg = love.graphics.newImage('Assets/Menu.png')
love.window.setMode(800, 600)
end
function love.draw(dt)
if Room == 0 then
love.graphics.draw(menuImg, 0, 0)
end
if Room == 1 then
gameMap:draw()
player.draw()
end
if debug == true then
love.graphics.print("Current FPS: "..tostring(love.timer.getFPS( )), 10, 10)
end
end
function love.update(dt)
if Room == 0 then
if love.keyboard.isDown('space') then
Room = 1
end
end
if Room == 1 then
player.Update(dt)
if love.keyboard.isDown('escape') then
Room = 0
end
end
if love.keyboard.isDown('t') then
debug = not debug
end
end
and this is my player.lua script:
-- PLAYER SCRIPT
player = {x = 50, y = 50, speed = 3, state = 0, img = nil}
function player.load()
playerRight = love.graphics.newImage('Assets/playerRight.png')
playerLeft = love.graphics.newImage('Assets/playerLeft.png')
playerUp = love.graphics.newImage('Assets/playerUp.png')
playerDown = love.graphics.newImage('Assets/playerDown.png')
player.img = playerDown
end
function GetInput()
if player.state == 0 or player.state == 1 then
if love.keyboard.isDown('w') then
player.y = player.y - player.speed
player.img = playerUp
elseif love.keyboard.isDown('s') then
player.y = player.y + player.speed
player.img = playerDown
end
if love.keyboard.isDown('a') then
player.x = player.x - player.speed
player.img = playerLeft
elseif love.keyboard.isDown('d') then
player.x = player.x + player.speed
player.img = playerRight
end
end
end
function player.update(dt)
GetInput()
end
function player.draw()
love.graphics.draw(player.img, player.x, player.y)
end
Any help would be much appreciated!
I have severall Hints for you
Unclear
It looks you write it under Linux but should it also run under Windows?
If so, use OS independent folder delimiter ( the dot ) in require()
.
Example
player = require 'Scripts.player'
In General: Dont use Slash / Backslash \ in require()
Tip: LÖVE uses LuaJIT with modified Lua 5.1 check the Windows OS is easy
(For deciding to use Slash or Backslash (not in/for require()
))
Clear
As @Luke100000 mentioned...
A Script for require has to return something.
If not than only a true wil be cached and a next require returns only true.
Therefore your player.lua content should be...
-- player.lua
local player = {x = 50, y = 50, speed = 3, state = 0, img = nil}
-- player.load() will be local
-- GetInput() wil be global
-- And the last line...
return(player)
