    in Announcements
    Hello,

    A new Gideros version is available, mainly focused on performance improvements in specific cases.

    Full change log:
    Improvements
    [gfx/sprite] new 'addChildrenAt' call to add several children to specific positions inside a sprite in one call (faster)
    [gfx/particles] addParticles is much more efficient with a lot of particles
    [export/html5] Change code to support WASM64 (not yet enabled)
    [layout] getLayoutContsraints, getLayoutParameters and getLayoutInfo now accept a mask of needed values in return for faster processing
    [styling] More color operations in styles

    Fixes
    [export/html5] Fix some existing files not replaced on export
    [plugin/tts] Use correct lua context in callbacks
    [Library] Fix 3D library shader

    Download it from here:

      Yes @MoKaLux, I didn't explain how to use those new functions.
      Sprite:addChildrenAt() takes a single argument, a table with keys indicating the position where to add a new child, and values the children themselves.
      Exemple:
       parentSprite:addChildrenAt({1=child1, 3=child3})

      Another example for Sprite:getLayoutParameters()
      -- Return a table containing only the computed cellSpacingY of the layout, instead of returning everything
local lp=sprite:getLayoutParameters(true,Sprite.LayoutKeys.cellSpacingY)

      I tried but got this instead :|
      local sprite = Sprite.new()
local pix = Pixel.new(0x0000ff, 1, 32, 32)
pix2 = pix:clone()
pix3 = pix:clone()
pix2:setColor(0xff0000)
pix3:setColor(0x00ff00)
-- position
pix:setPosition(1*32, 1*32)
pix2:setPosition(1.5*32, 1.5*32)
pix3:setPosition(2*32, 2*32)
-- order
sprite:addChild(pix)
-- Expected '}' (to close '{' at column 22), got '='
--parentSprite:addChildrenAt({1=child1, 3=child3}) -- not ok
--sprite:addChildrenAt( { 2=pix3, 3=pix2 } ) -- not ok
--sprite:addChildrenAt { 2=pix3, 3=pix2 } -- not ok
 
local pixs = {}
pixs[1] = pix3
pixs[3] = pix2
sprite:addChildrenAt( pixs ) -- OK
 
stage:addChild(sprite)

      Example for new 'brightness' operator in style tables:
      local stageStyle={
	baseColor=ColorValue(0.7,0.6,0,1)
}
 
local spriteStyle={
	__Parent=stageStyle, --Inherits from 'stageStyle'
	color1="=baseColor:brightness:1.1",
	color2="=baseColor:brightness:0.8",
}
for x=1,4 do
	for y=1,4 do
		local gradient=Pixel.new(0xFFFFFF,1,32,32)
		gradient:setPosition(x*32,y*32)
		gradient:setStyle(spriteStyle)
		gradient:setColor("color"..(1+((x+y)%2)))
		stage:addChild(gradient)
	end
end
 
stage:addEventListener(Event.MOUSE_DOWN,function() 
	stageStyle.baseColor=ColorValue(math.random(),math.random(),math.random(),1)
	stage:setStyle(stageStyle,true)
end)

      @MoKaLux,

      Sorry right syntax was probably:
       parentSprite:addChildrenAt({[1]=child1, [3]=child3})

      There was a little bug in the binaries, I have updated them a few minutes ago. If you already downloaded them, the new style functions weren't completely correct.

      Also, Sprite:addChildrenAt() can also be used like this:
      parent:addChildrenAt({ child1, child2, child3 })

      ok I added a couple of the new functions (plus some more) :p :
      - Sprite:setHiddenChildren
      - Sprite:isOnStage
      - Sprite:setStyle
      - Sprite:resolveStyle
      - Sprite:addChildrenAt

      Those are missing because I couldn't wrap my head around them :/ :
      - sprite:setWorldAlign
      - sprite:updateStyle (is this one actually really easy?)
      - sprite:spriteToLocalMatrix

      Viva Gideros!

      Sprite:setWorldAlign(boolean) instructs Gideros to align the Sprite position on a screen pixel. This is useful for Textfields since it makes the text look more sharp.
      Sprite:spriteToLocalMatrix(otherSprite) returns a Matrix that transforms a coordinate in otherSprite space into a coordinate in current sprite space.

      Sprite:updateStyle() performs what need to be done when the style table of a Sprite has changed. It is called automatically by Gideros or when application:applyStyles() is called.
      It can be overriden by your own classes if needed, so it is lua visible so that you can call it in such cases.

      Gideros does set 'compileSdkVersion' in the build.gradle if it was able to find it. I will investigate further.

      I found what's the problem.
      In export project you must fill Android SDK version (optional) too.

      When I export to html and run it in firefox / mac I get splash screen and spinning gideros icon. I get the following error: Loading failed for the with source “localhost:8888/gideros-wasm.js”. That file not exported. It doesn't work with previous version either so it is not a new problem.

      OK - Found a workaround that works. It happens when you check the enable PWA and compressed files. If you uncheck both of them it works. I haven't narrowed it down to specific checkbox as the cause but it one of those 2.

      We should remove compression mode anyhow. Most web servers do perform gzip compression on the fly and some android devices tinker with the .png that holds compressed data.

      hello gideros people, hope you are doing well :)

      I just found this folder C:\Program Files\Gideros\Players\WinRT which has many version of giderosgame.Windows_XXX_Test:
      - giderosgame.Windows_2025.3.0.0_Test -> 54.1Mb
      - giderosgame.Windows_2025.7.0.0_Test -> 38.9Mb
      - giderosgame.Windows_2025.9.0.0_Test -> 36.5Mb
      - giderosgame.Windows_2025.10.0.0_Test -> 39.2Mb

      I think those are created when compiling Gideros from source so this won't make Gideros.exe smaller but could save some space on one's HD 😛

      Hope all you guys are doing great 🙋‍♂️
      I am experiencing some little bugs in Gideros Studio 🤔: while coding, the studio is doing its stuff for word highlighting as usual.

      I realize now that when you want to do a right click with the mouse and the highlighting is not done yet then the mouse click won't register!

      I thought I had a virus at first but realized that was only happening while I was on Gideros, I am safe 🙂.

      That's it! Viva Gideros!

      I am trying RenderDoc on my win32 exported gideros app but it complains:
      "OpenGL. Context not created via CreateContextAttribs. Capturing disabled. Only OpenGL 3.2+ contexts are supported"

      As per google this means:
      The message "OpenGL. Context not created via CreateContextAttribs. Capturing disabled. Only OpenGL 3.2+ contexts are supported" means that your application is creating an older, legacy OpenGL context (typically version 2.1 or earlier). RenderDoc requires an OpenGL 3.2 or later core profile context for capturing and debugging

      The question is: does Gideros really use OpenGL version 2.1 or earlier on win32 exported apps? 🤔

      I don't like https://www.gideros.rocks/ first paragraph and english not being my mothertongue, so I asked ai 🤷‍♂️
      please rephrase this sentence: "Gideros is free and open sourced and provides the cross-platform technology to create amazing games. In a couple of hours, you’ll find yourself building and running your next great game."

      Here are a few ways to rephrase the sentence, depending on the tone you want:

      **Professional & Concise**
      > "Gideros is a free, open-source engine that offers cross-platform tools for game development. You can start creating and running impressive games in just a few hours."

      **Enthusiastic & Marketing-Focused**
      > "Harness the power of Gideros to build amazing games across all platforms. This free, open-source software is so intuitive that you’ll be developing your next big hit in a matter of hours."

      **Casual & Friendly**
      > "Gideros is free and open-source, making it easy to build awesome games for any platform. You'll be surprised how quickly you can get your next game up and running—often in just a couple of hours!"

      **Short & Punchy**
      > "Create amazing cross-platform games fast with Gideros. It’s free, open-source, and gets you building and running your next project in only a few hours."

      **Action-Oriented**
      > "Start building your next great game today with Gideros. This free, open-source technology provides the cross-platform tools you need to go from concept to a running game in just a couple of hours."

      Seems like many other tools behave the same: for instance https://forum.juce.com/t/creating-an-opengl-3-2-context-easy-fix-included/48872
      Gideros doesn't use CreateContextAttribs, but it definitely could. According to other sources (https://community.khronos.org/t/wglcreatecontextattribsarb-not-needed-anymore/70936), it seems that not using it doesn't mean we don't get a 3.2 context.

      I will patch Gideros code to use it anyway.
