boipushy (Input handling)

[adnzzzzZ]

Maybe you're still calling input:update()? In the new version you shouldn't call it because it's implicit. So if you call it will happen twice (your call and the implicit one)

Thank you! That was the problem.

Is it just me or this library's pressed/released functions stopped working in this new LOVE update?
I'm trying to fix it, but not so lucky so far.

I updated this library with a new function: pressRepeat. This function allows you to trigger events on an interval if a key is held down, instead of it doing it every frame. So this:

Code: Select all

function love.load()
    input:bind('mouse1', 'some_action')
end

function love.update(dt)
    if input:pressRepeat('some_action', 0.5) then print(love.math.random()) end
end

Will print a random number to the console every 0.5 seconds from when left click is held down. You can see more about the library here:

Neat little library, I like it.

A note about gamepad handling, love makes use of the SDL_GameControllerDB, however the version they ship with is only updated whenever a new version of love comes out. Normally this isn't a problem, but it you want to be as up-to-date as possible (or allow players to manually update it), use something to this effect:

Code: Select all

pcall(love.joystick.loadGamepadMappings, 'gamecontrollerdb.txt')

We don't actually ship with that database. SDL has an internal list it uses, and that database is someone else's (useful) list of extra devices that aren't necessarily in SDL's list.

I updated this with better explanations on the page and also a new function called sequence. The sequence function allows you to check for sequences of buttons pressed within an interval of each other. For instance:

Code: Select all

function love.update(dt)
  if input:sequence('right', 0.5, 'right') then
    -- dash right
  end
end

In the example above the sequence function will return true when the 'right' action is pressed twice, and the second key press happened within 0.5s of the first. This is useful for simple things like dashing, but also for more complex sequences like combos. This function must be started and finished with an action, and between each action there should be the interval limit.

I am playing with boipushy and when i try delay, interval or sequence features events are called immediatly

is there something i missed to enable those features?

i wrote it like in documentation:

Code: Select all

if game.playerController.input:down('f', 100) then
	print('f')
end

Code: Select all

if game.playerController.input:sequence('a', 0.5, 'a') then
        print('sequence a')
end

this print in my console "f" every update , same for sequence it print "sequence a" even if pressed a one time

Hello, for some reason this is failing for me:

Code: Select all

function love.update(dt)
    --[...] some irrelevant code before this
    if input:pressed('walk_left') and character.deltaX > 0 then 
        character.deltaX = 0 
        print("stop left")
    end
    if input:pressed('walk_right') and character.deltaX < 0 then 
        character.deltaX = 0 
        print("stop right")
    end
    if input:down('walk_left') then 
        character.deltaX = character.deltaX - 30 * dt 
    end
    if input:down('walk_right') then 
        character.deltaX = character.deltaX + 30 * dt 
    end
    character.x, character.y = world:move(character, character.x + character.deltaX * dt, character.y + character.deltaY * dt) --I'm using bump
end

I added the prints for debug purposes, I get the "stop right" every frame when holding 'walk_left'. I'm not sure if my code is at fault here. If I hold walk_left or walk_right without pressing the opposite direction it works fine.

Edit: figured it out, I had my own definition of love.keyreleased in main.lua.
