Game closes as soon as it starts.

[Branch Greenwood]

Hello, I have a problem with the game I am currently trying to make. More specifically I have a chunk of code that appears to cause a crash at startup. More specifically this chunk which is inside of love.update.

Code: Select all

--set apple
	if apple.spawned == false then
		--is apple.x on player?
		local x = 0
		while x == 0 do
			apple.x = love.math.random(0, (wWidth - apple.size))
			if (apple.x + apple.size) < player.x or apple.x > (player.x + player.size) then
				x = 1
			end
		end
		
		--is apple.y on player?
		local y = 0
		while y == 0 do 
			apple.y = love.math.random(0, (wHeight - apple.size))
			if (apple.y + apple.size) < player.y or apple.y > (player.y + player.size) then
			y = 1
			end
		end
		--apple has spawned
		apple.spawned = true
	end

What I want to do is choose a random coordinate for x and check if set position is on the player, if it is not then repeat the same for y and set the apple once things check out fine. I have sent the code to a friend of mine who has successfully executed it and played, I however could not. I tried running it using the 32-bit and 64-bit engines (love 0.9.1) to no avail. If it's of any relevance I'm running all of this on my Win7 x64 Virtual Machine on VirtualBox. I have attached the .love if you wish to check it out. Help will be greatly appreciated.

This is my first time posting on theses forums so my apologies if I haven't added something necessary for you to assist me, simply tell me and I will do my best to fill you in on the missing details.

Thanks in advance.

Hi and welcome to our forum.

I got this error message, when I ran the code:

Code: Select all

Error: Syntax error: main.lua:53: 'then' expected near '�'

The reason is that before the "<" there is an invisible character, that looks like a " " but it isn't. To make it run, remove this invisible character and replace it by a space.

Don't worry. You provided all necessary information.

If next time the love game immediately closes on start up, try running it from a console. That way you get an error message as text output.

Thanks a lot for the help. How do I run my game from a console?

Sorry, I don't know how to run from console in Windows, because I'm on linux. Hopefully somebody else can help out here.

On Windows, you have to put a file called [wiki]conf.lua[/wiki] in the same folder as main.lua, setting the "console" property to true. On other OSes, you should call "love path/to/game/folder (or .love file)" in a terminal.
