Gideros 2022.5

hgy29

Gideros 2022.5 is available, with a bit of headroom for hot fixes

Two major additions this time:
Sprite cloning: Now Sprite can be cloned instead of having to recreate and re-customize them from lua. This is a big performance improvement if you need several similar Sprite on screen, in particular if those sprites are complex or compound. Imagine you need to create 100 cells in a board game, with a complex stacking such as a background, a foreground, and possible icons over the top of each cell. Previously you had to create and customize 300 or 400 sprites to achieve that, now you can just make one, clone it 100 times, and just customize the delat between each cell.
This won't speed up rendering, but will save time preparing the scene.

3D particles: Particles sprite gets a 'z' coordinate to support 3D, but that's not all. Enabling 3D mode tells Gideros to make sure that the particles are drawn always facing the camera, and further enabling auto sorting tells Gideros to sort particles back to front to correctly process alpha. Whats more, and this applies to 2D partciles as well, decay can now be separated into x,y and z coefficients, particles now handle acceleration, and you can assign multiple textures to your particles for use with a custom shader.

This new Gideros version also comes with bug fixes and various improvements from the community. Thanks to everyone who contributed.

May I add:
- new Color Picker in the toolbar (highlight a hex color in your code and click the button = magik)
- wrap/unwrap lines in the toolbar too
- new append toolbar to menu in preferences

Thanks for your hard work people

Indeed @MoKaLux, I forgot those nice additions by @hito9, thanks to you both.

hey guys there is no gtween.png in C:\Program Files\Gideros\Resources\start\images
https://github.com/gideros/gideros/blob/1c4583c4e024d8b4925e65cc7b31b39676aa69a9/ui/Resources/start/examples.xml#L45

I took an image from gtween example if you want to put it there

It seems something has changed for TextField.new(...)
TextField.new(font,text,sample,layout)
Now, if you give sample a value this will crash your app! Tested with Gideros 2022.5.1
Example that makes Gideros 2022.5.1 crash:

local text = TextField.new(nil, "hello", "hello") stage:addChild(text)

cf: https://github.com/gideros/gideros/blob/5292e2d5884bd67dd3216090d58bc1d39eb39dba/luabinding/textfieldbinder.cpp#L51

Is this the new way to go?
TextField.new(font,text,layout)
(will update the wiki as soon as somebody confirm )

It was a bug, fixed in https://github.com/gideros/gideros/commit/fb3ea5dc684136361acb990d5fef3ad71ec2c276

Destructors does not work anymore?

local function destructor(...) print("destructor call", ...) end   local Foo = Core.class() local Bar = Core.class(Foo, nil, destructor)   bar = Bar.new()   Timer.delayedCall(1000, function() print("deleted?") bar = nil collectgarbage() end)

It seems so. I digged a bit and it is due to the switch to luau, which removed __gc metamethod and restrict the use of destructors to native code. I will try to patch luau to make destructors available again in some form.

Well, its not realy usefull I think, so maybe we can remove it aswell?)

Btw, found another bug. You cant remove event listener with "removeEventListener" function.
"removeAllListeners" works fine.

local TestScene = Core.class(Sprite)   function TestScene:init() self.timer = 0 self:addEventListener("enterFrame", self.update, self) end   function TestScene:update(e) self.timer += e.deltaTime if (self.timer > 0.1) then print("Update") self.timer = 0 end end   function TestScene:removeListener() self:removeEventListener("enterFrame", self.update) end   local scene = TestScene.new()   Timer.delayedCall(1000, function() print("!!! Remove !!!") scene:removeListener() end)

Outputs:
