If you had zipped the contents of the folder "basics", then you could rename that to .love, but anyway.

I can't reproduce your error, it all works fine.

But nothing happens when I press the B key or let go of it, and there's no message when I exit the game, even though I pasted the functions for them into the main.lua. Is it just that I have a retarded operating system?

Code: Select all

function love.keypressed(key)
   if key == 'b' then
      text = "The B key was pressed."

Where's the value of text?
Also, you put love.draw as the second function. It should be the last.

Well it didn't bring up values in the wiki's callback function tutorial. So sorry to be wasting people's time by the way, I just don't know where else to look for help.

Is it possible to get the width and height of a quad? quad:getWidth() and quad:getHeight() don't seem to exist.

[wiki]Quad:getViewport[/wiki] gets the viewport's top-left position and width and height.

[Jasoco]

Oh awesome! So obvious. Somehow it didn't click when I looked through the list of functions. I guess I didn't associate a viewport with dimensions. But it makes so much sense. Thanks!

I've generated a canvas (canvas1) and need to duplicate it into a new canvas (canvas2) so I can manipulate canvas2 without changing canvas1. Would it be more efficient to simply draw 2 canvases from the start and draw to both at the same time, or is there an efficient way to copy a canvas into a new canvas?

If I have to just create 2 canvases from the start, is drawing to both using multicanvas significantly faster, or just syntactically nicer?

[s-ol]

This is just guessing really, but I would suppose that drawing using multicanvas is the fastest as the whole pipeline only runs once (except for the fragment shader ?).

Instead of drawing the scene twice you can also just draw one Canvas onto the other to copy it.

I am trying to run ndk-build on the love-android-sdl2 repo.
I am using windows, and when run "ndk-build", it shows the message: "The system cannot find the path specified."
I am following the wiki: https://bitbucket.org/MartinFelis/love- ... _-_Windows

Thank you. and sorry for the silly question
