thx，that’s true

https://love2d.org/wiki/love.graphics.setMode -> Removed in LÖVE 0.9.0; Moved to the love.window module as love.window.setMode. https://love2d.org/wiki/love.window.setMode Interestingly, your link to the physics tutorial on the wiki shows love.windows.setMode being used, and that should work. Edit:...

Welcome to the forums! We will be able to help you more if you post the line of code in which the error has happened, or maybe the entire code, even if you copied it. My only guess is that you replaced "window" with "graphics", or you are using an outdated version of love2d. thx...

wiki page:Tutorial:Physics
I read this tutorial and copy the whole code,
but it doesnt work and warn:Error main.lua:33:attempt to call field'setMode'(a nil value)
help me~ better in chinese~
