Run a different file *solved*

[TeeJayz]

In main.lua, how do you run a different .lua file? I need this for a menu screen because I cannot undraw images. I dont think I need to post any code, so any answers?

To load a different file you have to put require "filename" (IMPORTANT: Make sure you put the file NAME, but not the extension. So require "menu" not require "menu.lua".)
Now none of your code is going to be run, unless you call those functions inside of the main love. functions. Here's an example.

This is what your menu.lua could look like

Code: Select all

function menu_load()

--Menu loading stuff

end
function menu_draw()

-- Menu drawing stuff

end
function menu_update(dt)

-- Menu updating stuff

end

And now here is what your main.lua could look like

Code: Select all

require "menu"

function love.load()

menu_load()

-- Other loading stuff
end

function love.draw()

menu_draw()

-- Other drawing stuff
end

function love.update(dt)

menu_update(dt)

-- Other updating stuff
end

And that's all it takes to run stuff from other files.
One more little thing to note. When you have a parameter that you want to use inside one of your functions (For example, dt in menu_update) you must have that parameter written when you call it. So like this

Code: Select all

function menu_update(dt)
--Dt stuff
end

That is fine as long as you call it like this

Code: Select all

function love.update(dt) -- You need to have dt in this as well
menu_update(dt) --See the dt
end

I cannot undraw images

You don't need to.

Every frame, the screen is cleared. Every frame, love.update() and love.draw() are run. Use if statements and for loops and so on to decide what should be drawn.

I dont know how to go forward 1 frame.

It happens automatically. You don't need to worry about that.
