Gideros 2023.9 Released

hgy29 · September 2023

This new Gideros released is focused on memory consumption. A lot of work has been done to allow dealing with a lot of sprites without taking too much memory. A typical Sprite used to take 2kB of RAM, they are now 30% lighter. It is something, but not enough if you want to draw millions of sprites, so a new feature has been introduced: Ghosts

Ghosts are kind of lightweight Sprites: you tell Gideros to render the same real Sprite with slight variations. Not everything is possible, but it currently supports changing the layout position (gridx/gridy in layout constraints), the color of a pixel, the text and color of a textfield. More will be added in the future. The idea is that those ghosts only take a hundred of bytes of memory, since they share the rest of the settings with the original real Sprite. With this system, Gideros can now render a table of several millions of cells at a fraction of the memory cost of full Sprites.

Another new feature: you can now create sounds directly from a lua array, simplifying the use of sounds in Gideros pure code demos, and allowing lua generated sound streams.

For the full list of additions and changes, see below:
New features

[core] Add math.fft() and math.ifft()
[gfx] Implement Sprite ghosts (Sprite,Pixel,TextField)
[audio] Allow to create sounds from raw waveform data
[export/linux] Support fullscreen and Screen API

Improvements

[layout] Reduce memory usage
[layout] Add a fixed grid layout parameter telling Gideros to ignore children size requirements
[gfx] Deactivate clipping when 3D transform is detected
[gfx] Significantly reduce sprite memory usage
[gfx/textfield] Faster recoloring in most cases
[gfx/pixel] Reduce memory usage
[gfx/movieclip] Make native tween functions available to lua
[audio] Allow streaming a wave file
[studio] Add icons for Apple and Linux exports
[export/uwp] Use UWP Storage API to access files outside sandbox

Fixes

[library/3d] fix missing alpha value for fbx (json) models
[gfx/layout] Avoid setting invalid bounds on sprites (if computations are still ongoing)

is the midi plugin supported by the linux export? and the qt-based linux export?

hgy29 · September 2023

@keszegh, neither of them I believe, but I’ll check

vitalitymobile · September 2023

That's awesome! Thank you so much! There are so many exciting upgrades in this new version!

that's what i assumed by not having seen it in the plugin folders of the exports. could it be added perhaps? thanks

also, wacom pen pressure support should work in linux-qt i guess (am i right?), what about the other linux export?

keszegh · September 2023

about ghosts, i assumed that particles have a similar purpose, what is the advantage of ghosts?

hgy29 · September 2023

Advantage of ghosts is that they can be a whole sprite tree, and any kind of Sprite.

About Linux Wacom support, we use glfw library to talk to X server, which doesn’t handle touch at all.

EDIT: There are plans to add touch support to GLFW, but can't tell if/when that'll be done: https://github.com/glfw/glfw/pull/1736
In the end, it would be great to remove the need for GLFW and deal with X server directly, but that's probably a lot of work and learning

is there a chance to support wacom on one of the exports sometime in the future?

You are asking too much I am afraid, even in touch become supported some time in the future, wacom is yet another subject

thanks, i will stick to that as of now. i hope adding midi support will work though.

It builds fine at least: https://github.com/gideros/gideros/commit/f4919e602b5c0be83ab949a15dabdda1546287b3
Do you want me to send it to you for testing ?

instead of touch i've found stuff about supporting wintab in glfw, which would be also good for wacom.
see e.g., https://github.com/glfw/glfw/issues/403
but it is not clear to me if there is a working solution or not.

sure, i'd be happy to test.

hgy29 · September 2023

Here it is, merge it with your existing All plugins/luamidi folder

MoKaLux · September 2023

Thank you for this new release

Ghost question: is it automatically applied?

I tried this code with no luck

local pixel = Pixel.new(0x0, 1, 128, 128)
pixel:setPosition(128*2, 128*2)
--pixel:applyGhost()
local gpixel = pixel:applyGhost()
stage:addChild(gpixel)

hgy29 · September 2023

I’ll try to come with an example of ghost use in a few days

MoKaLux · September 2023

~~And I will do the wiki please~~

DONE in the Sprite class (I only copied hgy29 text and sample code below

). Plus added fft ifft to Math.

hgy29 · September 2023

A quick demo of ghosts:

--Layouts are computed from stage, configure a single sub cell, taking all space
stage:setLayoutParameters({rowWeights={1},columnWeights={1}})
 
--Make a grid of 24 rows, 8 columns with cells of 40x20 units
local rn,cn=24,8
local grid=Pixel.new()
local rh,cw={},{}
for i=1,rn do rh[#rh+1]=20 end
for i=1,cn do cw[#cw+1]=40 end
grid:setLayoutParameters({rowHeights=rh,columnWidths=cw})
grid:setLayoutConstraints({fill=1})
stage:addChild(grid)
 
-- Create cell template
cell=Pixel.new()
cell:setLayoutConstraints({fill=1})
local ic=Pixel.new(0,1,10,10)
ic:setPosition(5,5)
cell:addChild(ic)
local tf=TextField.new(nil,"",{ flags=FontBase.TLF_REF_TOP|FontBase.TLF_VCENTER|FontBase.TLF_CENTER, w=20, h=10})
tf:setPosition(20,5)
cell:addChild(tf)
 
--Create ghosts
local ghosts={}
for i=1,rn do 
	for j=1,cn do
		ghosts[#ghosts+1]={ model=cell, -- Specify ghost model
			gridx=j-1, gridy=i-1, -- Place this ghost in the grid
			color=math.random(0xFFFFFF), -- A random color for this cell
			children={
				{ color=math.random(0xFFFFFF), }, -- First child is the icon (ic), set a random color
				{ text=math.random(10) }, -- Second child is the textfield, set a random number
			}
		}
	end
end
 
--Apply ghosts
grid:setGhosts(ghosts)

I've made a quick update to this release, now it will be 2023.9.1 with:
- Improved particles: 32bit indices and new Particles:getNumParticles() call
- Ghosts now support a 'transform' parameter, which will be a 'Matrix' object
- MacOS fixes
- Linux luamidi plugin
- And more various fixes

I seem to have an issue with composite fonts

local ttfont1path = "fonts/JetBrainsMono-Regular.ttf"
local of5 = TTFont.new(ttfont1path, 24, "", true, 3) -- outlined
local nf5 = TTFont.new(ttfont1path, 24, "", true, 1) -- normal
cf5= CompositeFont.new{
	{ font=of5, color=0x0, x=1, y=2 }, -- outline
--	{ font=nf5, color=0xffffff }, -- DOESN'T WORK IN GIDEROS 2023.9+
	{ font=nf5, }, -- BUT THIS WORK!
}

It seems CF doesn't treat children color, alpha, x and y, correctly, or is it supposed to be like this?!

Thank you

EDIT: nevermind I found the issue, now alpha is not optional anymore, if you pass a color then you must pass its alpha as well. Issue solved

What are you expecting ?

MoKaLux · September 2023

thank you hgy29, please see my EDIT above. This works now:

-- fonts
local ttfont1path = "fonts/JetBrainsMono-Regular.ttf"
--
local ttfo5 = TTFont.new(ttfont1path, 24, "", true, 8) -- outline
local ttf5 = TTFont.new(ttfont1path, 24, "", true, 1) -- normal
cf5= CompositeFont.new{
	{ font=ttfo5, color=0x0, alpha=1, x=-1, y=-1 }, -- outline
	{ font=ttf5, color=0xff0000, alpha=1 }, -- normal
--	{ font=ttf5, }, -- normal
}

I post my edit here as well

hgy29 · September 2023

Oh, I see, I’ll make alpha optional then

don't worry hgy29, I updated the wiki

MoKaLux · September 2023

I have a question regarding keycode please

Would it be possible and easy to have all the NUMPAD keys available?
NUM_DOT, NUM_ENTER, NUM_PLUS, NUM_MINUS, ...

Second question: would it be possible and easy to have MODIFIERS work with the NUMPAD keys (like in Gideros Studio)?
ALT CTRL SHIFT + NUM_0, NUM_1, NUM_2, ...

I have tried the following code but it is not working for me:

	self:addEventListener(Event.KEY_DOWN, function(e)
		local modifier = application:getKeyboardModifiers()
		local modif = (modifier & KeyCode.MODIFIER_SHIFT) > 0
		--
		if e.keyCode == KeyCode.SPACE then self.isplaying = not self.isplaying
		-- ...
		elseif e.keyCode == KeyCode.NUM_1 then self:modelFRONT()
		elseif e.keyCode == KeyCode.NUM_3 then self:modelRIGHT()
--		elseif (modif and e.keyCode == KeyCode.NUM_1) then self:modelBACK()
--		elseif (modif and e.keyCode == KeyCode.NUM_3) then self:modelLEFT()
		elseif e.keyCode == KeyCode.NUM_4 then self:modelBACK()
		elseif e.keyCode == KeyCode.NUM_6 then self:modelLEFT()
		-- ...
		end
	end)

Thank you

PS: regarding below answer by hgy29, that is awesome, thank you very much captain

hgy29 · September 2023

@MoKaLux: https://github.com/gideros/gideros/commit/cfd0cb03080c7734b11d0a320ae9fe20b2988071

Modifiers should already work with numpad keys, except they weren't defined. By the ways you should use 'e.modifiers' instead of getKeyboardModifiers()

MoKaLux · September 2023

I compiled with the changes and it is working, thank you hgy29

Some sample code:

function TheStage:myKeysPressed()
	self:addEventListener(Event.KEY_DOWN, function(e)
		-- ...
		elseif (e.modifiers == KeyCode.MODIFIER_CTRL and e.keyCode == KeyCode.NUM1) then self:modelBACK()
		elseif (e.modifiers == KeyCode.MODIFIER_CTRL and e.keyCode == KeyCode.NUM3) then self:modelLEFT()
		elseif e.keyCode == KeyCode.NUM1 then self:modelFRONT()
		elseif e.keyCode == KeyCode.NUM3 then self:modelRIGHT()
		-- ...
		end
--		print(e.keyCode, e.realCode, e.modifiers)
	end)
end

PS: warning, wiki updated with those changes for the next Gideros https://wiki.gideros.rocks/index.php/KeyCode_Constants

zeroexu · September 2023

Hello!

I downloaded this version on Windows and I wanted to export for Android but it doesn't write the package name in the exported Android manifest.

Is that a bug?

MoKaLux · September 2023

@zeroexu are you exporting to apk, aab or android studio please?
