    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.
