LÖVE

Hi i am working on a project for school and need help with my collision i have it written but it give the error "attempt to index field '?' (a nil value). Have had a slight look at it and tried to research it but to no prevail, your help would be great

Welcome to the forum!
Your collision still isn't working, but I've fixed the error you've been getting. What you were doing was accessing the table by the player x and y. The problem was however, that your map table didn't include tiles for every single pixel on the screen, which it shouldn't. So to fix this you would get the tile that the players coordinates were on. So you would replace line 121 with: The 16 is because you have tiles with width and height of 16.
That'll fix your error.
Hope that helps.

P.S Also next time you should post requests for help in the Support and Development forum, not general.
