[FIXED] Yet Again: Fails to index field "?"

[B-Man99]

I started a new project yesterday, this one I'm hoping to make into a full-feature game, unlike quick things I've been working on in the past year to get me used to Love2d, etc. I've isolated the loadLevel function, because if I remove the line in love.load() that calls loadLevel(), the game starts without any errors. Most bugs I am able to think about a little (or a lot) and fix, but this particular error is harder for me. Love2d fails to index a nil field, but I cannot seem to figure out what that field is. Can anyone please explain how to fix this error, or give me any advice? Thank you, it would really help!

Well, thankfully the error gives us a location, main.lua:157, so I look at that and see 3 table index operations that could cause this, namely grid[x], grid[x][y] and leveldata. So, I added the following code (before 157):

Code: Select all

print(grid[x])
print(grid[x][y])
print(leveldata[i])

That showed me the error was in the second of the two lines, and the result of the print indeed showed grid[x] is nil.

Thanks, I would have done that except that my console opens up but doesn't print anything. I saw a similar problem on these forums but with no solution. Thank you for helping. Now I just need to figure out why grid[x] is nil. I'll update this post if I figure out why, but I could still use advice until then. Thanks, bartbes (I'd give you karma, but now there's no karma)

Update: bla bla bla

Edit: FIXED. THANK YOU FOR YOUR HELP
