Miscellaneous Bug

[kylewatson98]

I have 156 lines of code in the buggy class alone, one bug, but I have not got a clue why Also I think my code is inefficient/resource intensive I don't know how you guys can help me.
Here is the code for the buggy class:

Code: Select all

menu = {}
menu.__index = menu
function menu.create()
	local mnu = {}
	setmetatable(mnu,menu)
	mnu.open = true
	mnu.font30 = love.graphics.newImageFont("font/font30.png", " abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789.,!?-+/():;%&`'*#=[]\"")
	mnu.mute = love.graphics.newImage("font/mute.png")
	mnu.n_mute = love.graphics.newQuad(0, 0, 12, 18, 18, 18)
	mnu.alpha = {0, 0, 0}
	mnu.starttype = "Start"
	mnu.menutype = "Dodge Ballz"
	mnu.bg_song = love.audio.newSource("sound/primetime.mp3", "stream")
	mnu.bg_song:setLooping(true)
	mnu.bg_song:setVolume(0.25)
	mnu.bg_song:play()
	mnu.select = love.audio.newSource("sound/select.wav", "static")
	mnu.end_s = love.audio.newSource("sound/end.wav", "static")
	mnu.sndTime = 0
	mnu.mute = love.graphics.newImage("font/mute.png")
	mnu.n_mute = love.graphics.newQuad(0, 0, 11, 18, 18, 18)
	mnu.vol_width = 400
	return mnu
end

function menu:draw()
	--Set background rectangles
	love.graphics.setColor(224, 27, 150, 100)
	love.graphics.rectangle("fill", 0, 0, width, height)
	love.graphics.setColor(255, 255, 255, self.alpha[1])
	love.graphics.rectangle("fill", 0, height/2 - 95, width, 43)
	love.graphics.setColor(255, 255, 255, self.alpha[2])
	love.graphics.rectangle("fill", 0, height/2 -45, width, 43)

	love.graphics.printf("Volume", 0, height/2, width, "center")
end

function menu:update(dt)

	end
end

function menu:vol_change(x, y)
	if x > width/2 - 200 and x < width/2 and y > height/2 + 5 and y < height/2 + 48 then
		self.vol_width = ((width/2 - x) * -1) + 200
		self.bg_song:resume()

		end
		love.audio.setVolume(self.vol_width/400)
	elseif x > width/2 and x < width/2 + 200 and y > height/2 + 5 and y < height/2 + 48 then
		self.vol_width = (x - width/2) + 200
		love.audio.setVolume(self.vol_width/400)
	end
end

And this is the bug: "Syntax error: class/menu.lua: 51: function arguments expected near 'elseif' "
Much thanks in advance, Kyle.

Code: Select all

function menu:update(dt)
   if self:checkHov(height/2 - 95, 1, dt) then
      self:play_b -- you've forgotten something!
   elseif self:checkHov(height/2 - 45, 2, dt) then
      love.event.quit()
   elseif self:checkHov(height/2 + 5, 3, dt) then
      self:vol_change(love.mouse.getX(), love.mouse.getY())
   end
end

Maybe you didn't realise, but in lua you must always use parenthesis to call a function, even if it has no arguments.

Yeah, just slightly drunk at the moment and it was 'bugging' me But yeah, thanks a bunch c:
