How exactly does the love functions work? [more questions]

[Buddy4point0]

As long as I've been programming in lua, I've always had to do something like this:

Code: Select all

function blah
blah blah blah
end

function blah
blah blah blah
end

while true do
function
function
draw everything to screen
end

Does love automatically loop the draw function?
What other functions does love automatically loop?

Can someone explain basically how the format of love goes?

It is overridable even.

Basically, LÖVE loads the main.lua, then calls love.run.

love.run, by default, calls love.load when the window has been initialized, then starts a loop where it calls love.update, handles events, clears the screen, calls love.draw, and then presents the drawn stuff.

The loop is terminated if the "q" event is pushed by love.event.push.

Thanks! That's exactly what I needed to know.

Now more questions:

• Can you load things and set variables outside of the love.load function?
• Is it possible to get the color of one pixel on the screen in love? If so what's the function?
• Can you draw images to another image (for screen effects) for can you only draw images to the screen?

Yes.

Is it possible to get the color of one pixel on the screen in love? If so what's the function?

No. You can however get the colour of a pixel from an ImageData.

Can you draw images to another image (for screen effects) for can you only draw images to the screen?

ImageData:Paste might be what you're looking for.

With one more step inbetween you can: http://love2d.org/wiki/love.graphics.newScreenshot

Thanks again, and sorry for making you guys send me links from the wiki. I looked on there but I was having trouble finding everything that I need.

Wow, I didn't know about the [wiki] tag! That's incredibly useful!

You mean there's a wiki tag? Awesome. Let's try it: love.
EDIT: Yay it works!

But it doesn't work if there's a : in the title, which was how I saw it existed:

ImageData:Paste might be what you're looking for.
