Hello again.
How i can delete chink from code : chunk = love.filesystem.load ( name )?
My game spends more RAM and i want delete graphics with RAM after exit from locations.
Example:
I have 2 locations:
I entered in 1 location and i load graphics and code for this location. -> i left 1 location and i want delete source for 1 location and load source for 2 location.
How i can get it?
Sorry for my english

You can simply unset the variable(s) that holds the graphic and the garbage collector will pick it up. Just make sure you get rid of all the references if there are multiple.
Code: Select all
img = love.graphics.newImage( 'someImage.png' )
if level == 2 then
img = nil -- this will remove the image from memory
end

Good.
Can i delete all table in one moment?
table = {
img 1 = love.graphics.newImage( 'someImage1.png' )
img 2 = love.graphics.newImage( 'someImage2.png' )
}
Can i make it through "for"?
And this:
dosn't work

You can remove the entire table by just setting the table to nil (but again, make sure you've removed all references to it)
(Also it's a very bad idea to make a variable called table, because table is a default variable with a bunch of functions and you'll probably destroy some libraries. But I'm assuming this is just an example.)
What isn't working about img = nil ?

I delete all tables from 2 location and run again this and i take error what can't read table, but when i entered in location 2 i use require ( file ) where i keep all tables.
Maybe i need use love.filesystem.load instead of require?

When you do
then the varaible "table" does not exist anymore. Try
instead. This should replace the original table by an empty table.

Yes, i now.
But my code "require (file)" itself contains again it tables.
Nope. Again error.
