love.event.wait freezing game window

[Neox Hopper]

I'm trying to make a walking animation using this script:

function love.update(dt)
if love.keyboard.isDown("d") then
x = x + (speed * dt)
love.event.wait(1)
potato = right
end

However, when I enter the "love.event.wait(1)" code, it freezes the game window for 1 second. Is there a way to "wait," and not freeze the game?

(Sorry for posting so many threads, I'm very new to Lua scripting and most (informative) forum posts are usually out-dated or don't work.)

This looks like a job for a timer library. Take a look at hump.timer.
https://github.com/vrld/hump (library)
https://hump.readthedocs.io/en/latest/timer.html (timer docs)

It's OK to post new threads, but this looks more appropriate for the Support forum rather than General.

Do I drag the "hump-master" folder into my game's folder (folder with main.lua)?

How do you properly install and use the timer library? (which folder do you drag it to, which .lua file do you drag it to, ect.)

[pgimeno]

You only need timer.lua anywhere within that folder. You can create a folder called 'hump', or you can create a folder called 'libs' or however you prefer to organize it.

Then you require it with e.g. local timer = require("hump.timer") (if you stored it in a folder called 'hump').

I put the "hump" folder (with the timer.lua file in it) in my games folder and entered this script into main.lua:

local Timer = require("hump.timer")
function love.keypressed(key)
if key == 'a' then
Timer.after(1, function() print("Hello, world!") end)
end
end

function love.update(dt)
Timer.update(dt)
end

-but no "Hello world!" text was showing up in the game window when I press the "a" key. Do you know how to fix this issue?

Is the text being printed to the console? Your function added to the timer is calling print which adds text to the console.

[pgimeno]

Yeah, note also that LÖVE erases the screen every frame, therefore even changing print() to love.graphics.print() will not work at all. What you can do is set a variable in the timer, and print it in love.draw, like this:

Code: Select all

local Timer = require("hump.timer")

local TextToPrint = ""  -- Print an empty string until TextToPrint is changed

function love.keypressed(key)
  if key == 'a' then
    Timer.after(1, function() TextToPrint = "Hello, world!" end)
  end
end

function love.update(dt)
  Timer.update(dt)
end

function love.draw()
  love.graphics.print(TextToPrint)
end

Is it possible to do the same thing but with images?

Yes.
