Löve Frames - A GUI Library

[Rishavs]

The buttons are getting rendered but the click event is not firing.

[LaggyNewbie]

I have a game that does some deserializing of data using a serialize.lua library found on the forums.

With a os.clock() taken before and after running 1 deserialize() operation, the time is about .001 seconds.

Just by adding:

require("libs.loveframes")

and not even adding the update or draw events required by loveframes, the same deserialize() function process jumps to taking .7 seconds to complete.

Any idea why just including a require to loveframes makes my deserialize() operation increase by a couple orders of magnitude?

Can you post a .love of your project?

Love Frames performs several tasks when you require it, and I haven't really taken the time to optimize any of them.

I think I figured out the problem. There were global variable names being shared by both libraries (specifically the utf8.lua file) but not throwing any errors. I ended up changing the serialize library to Tserial.lua which doesn't appear to have any naming conflicts with the love frame library

I have the same problem as Rishavs - the .OnClick callback for buttons does not work.

Here's my code (relevant parts on top):

Code: Select all

function love.load()
	require("lib.Frames")
	
	button_circles = loveframes.Create("button")
	button_circles:SetWidth(200)
	button_circles:SetText("Toggle Lines")
	button_circles.x = 20
	button_circles.y = 20
	
	circles = false
		
	button_circles.OnClick = function ()
		circles = not circles
		button_circles:SetText("test")
	end

	love.window.setMode(1280, 800)
	math.randomseed(os.time())
	math.random(); math.random(); math.random()
	
	planet = {}
	t = 0
	
	--planets
	planet.number = math.random(10)
	sun = {}
	sun.radius = math.random(30, 50)
	sun.x = 1280/2
	sun.y = 800/2
	
	for i = 1, planet.number do
		planet[i] = {}
		planet[i].radius = math.random(5, sun.radius * 0.5)
		if i == 1 then
			planet[i].distance = math.random(sun.radius + planet[i].radius + 20, i*100)
		else
			planet[i].distance = math.random(planet[i - 1].distance + planet[i].radius + 20, i*75)
		end
		
		planet[i].T = math.pow(planet[i].distance, 3/2) * 10
		planet[i].t = t + math.random(100000)
		
		planet[i].x = sun.x + planet[i].distance*math.sin(2*math.pi/planet[i].T)
		planet[i].y = sun.y + planet[i].distance*math.cos(2*math.pi/planet[i].T)
	end
	
	
	
end

function love.update()	
	for i = 1, planet.number do
		planet[i].t = planet[i].t + 1
		planet[i].x = sun.x + planet[i].distance*math.sin(2*math.pi*planet[i].t/planet[i].T)
		planet[i].y = sun.y + planet[i].distance*math.cos(2*math.pi*planet[i].t/planet[i].T)
	end
	
	loveframes.update()
end

function love.draw()
	love.graphics.circle("fill", sun.x, sun.y, sun.radius)
	for i = 1, planet.number do
		love.graphics.circle("fill", planet[i].x, planet[i].y, planet[i].radius)
		if circles then
			love.graphics.circle("line", sun.x, sun.y, planet[i].distance)
		end
	end
	loveframes.draw()
end

It works flawlessly if I use .OnMouseEnter instead. It also works flawlessly in another older project, where I have _exactly_ the same syntax (and the libs were copied over from there).

I'll attach the .love

You need to add the mousepressed and mousereleased callbacks:

Code: Select all

function love.mousepressed(x, y, button)

	loveframes.mousepressed(x, y, button)
	
end

function love.mousereleased(x, y, button)

	loveframes.mousereleased(x, y, button)
	
end

Many thanks. Much appreciated. Me fail.

edit: While I'm at it, I have another question.
If I create slider and set it's default value, how do I get the slider to actually be at the corresponding point for that value? It's always stuck to the very left (horizontal slider) for me.

is it possible to rename love frames when requiring it?

Love Frames is returned when you require it, so something like this should work:

Code: Select all

gui = require("path.to.loveframes")

I'm trying to retrieve the name of an object using GetHoverObject, but having iterated through the table it returns, the names I gave the objects do not exist. Closest I get is "instance of class loveframes_object_imagebutton" or similar. I'm trying to retrieve the name to match it against a table value (the objects name). See "obj[x]"

Code: Select all

if loveframes.util.GetHoverObject() then
  obj = loveframes.util.GetHoverObject()
  for k, v in ipairs(tbl) do
    if obj[x] == v then
      ...
    end
  end
end
