Gideros 2020.11 released

hgy29 · November 2020

It has been available for download for a few days now, for testers, but hadn't been formally announced yet. Let's fix this.

Gideros 2020.11 improves text edition support functions and text layout, by properly handling a few corner cases, making it better at providing editable text fields. Actual edition code still needs to be written in lua, but gideros helps with text layout and caret positionnng.

Major work has been done in 3D field too: Gideros 2020.11 now comes with reactphysics 0.8 plugin (nice improvemnts over the previous version such as 'trigger' shapes and ability to resize collision shapes after creation, and an overall cleaner design). 3D Library support function have been switched to use lua shaders, and now use a better shadow rendering technique. Lua shaders have been improved to handle some forms of tail calls and more code sequences, as well as geometry instancing.

Once you master them, lua shaders are a killer feature of Gideros, and I'll start a new thread soon with some examples of lua shaders for you to use or modify.

Last thing worth noting: UWP export now requires DX10 feature level, instead of 9.3. I am confident most graphic cards do support DX10 today, and requiring DX10 allows to use shadow techniques in HLSL.

Full list of changes:
Improvements

[studio] Masquerade merged lua file names to mimic what is done on export
[core/font] Add missing getDescender() call
[core/path] get distance and auto segmentation in getPathPoints()
[gfx/backend] Expose projection matrix to shaders
[export/android] Provision for adding extra build targets to gradle call
[uwp] Request DX10 feature level
[plugin/imgui] Update
[plugin/rp3d] Update to 0.8.0 version
[library] Improve lua shader library
[library] 3D library now use lua shader for easier maintainability

Fixes

[core/font] Fix inconsistency on layout of empty lines
[core/text] fix getTextPositionFromPoint and interwork with layout
[core/text] More fixes regarding text point<>offset translation
[core/text] Fixed more issue regarding text layout (word-break, etc)
[core/pixel] fix setTextureMatrix()
[core/math] Fix minor lua stack issue
[gfx/metal] Fix setClip()
[uwp] Fix HTTP header managemenet (was growing request after request)

+10 for Lua Shaders, amazing work!

I got an error in android player:

main.lua:6: module 'ImGui' not found:
	no field package.preload['ImGui']

hgy29 · November 2020

@rraptor, is it your own custom player with imgui enabled ? I don't think imgui is a 'default' plugin yet

Ah, so I need to build a player for that, ok.

SinisterSoft · November 2020

I think that when imgui becomes one of the default plugins then a collection of all your demos for it within the demos folder would be great.

rrraptor · November 2020

There was a suggestion from me: http://forum.giderosmobile.com/discussion/comment/63432/#Comment_63432

So, here is my implementation: https://github.com/MultiPain/gideros/commit/94989c4640537918b1c4d8f2e38b4ba5de8bbc45
Syntax is

Sprite:isVisible([check_parents = false])

Another small suggestion is to add

MovieClip:isPlaying()

@rraptor, submit a pull request to gideros through github, I'll merge them ASAP

rrraptor · November 2020

Done.

Warning, it seems that Gideros doesn't work at all on macOS Big Sur (Updated my mac today). It also means that all Gideros apps previously made for Mac won't work either. It seems that upgrading to Qt 5.15 fixes this issue.

rrraptor · November 2020

@hgy29 I just realized that I forgot to add "MovieClip:isPlaying()" to loader functions list

Added another pull request

Yep:( Facing this issue too. Can't proceed my work now(

hgy29 · November 2020

I uploaded a 2011.1 version which support MacOS Big Sur, and includes a few fixes about Metal and additions by @rrraptor

I think I found a bug with alertdialog and html:

	if application:getDeviceInfo() == "Web" then
		local alertDialog = AlertDialog.new("html", "Not available for web, please download the app.", "OK")
		alertDialog:show()
	else ...
end

The first time you click the button that works ok. The second time you click it you have these error messages:

Uncaught DOMException: Node.removeChild: The node to be removed is not a child of this node gideros-wasm.js:337
button_handler https://v6p9d9t4.ssl.hwcdn.net/html/3076697/gideros-wasm.js:337
Uncaught DOMException: Node.removeChild: The node to be removed is not a child of this node gideros-wasm.js:337

onerror https://v6p9d9t4.ssl.hwcdn.net/html/3076697/gidloader.js:359

And the gideros-wasm.js lines:

var buttons = document.createElement("div");
 buttons.className = "gid_dialog_buttons";
 dialog.appendChild(buttons);
 var button_handler = function() {
  if (callback) {
   callback(gid, parseInt(this.getAttribute("id").replace("index_", "")), this.value, input ? input.value : null);
  }
  document.body.removeChild(container);
 };

gideros v2020.11.1 (I assume it's the same with v2020.12 as it was more focused on mac fixes).

There was a topic somewhere about "Core.class()" objects and their names. Is it still in TODO list?) Because right now obj:isInstanceOf(classname) is kinda useless if you class is not inherited from any other built in class.

It can't be done without API change at Gideros side, because Core.class takes a table as its argument, not a string, and hence doesn't know the name of your custom classes.
but Core.class() could be changed to accept string as its first arg too.

And all existing projects will break?

Or add a simple type check, if first arg is string then assign a name to this class?

Yes, a type check, but actually it is a new argument that is needed, we need to supply the name of the new class, not the one of the base class. I would make it the first optional argument

You can see the bug in action: https://mokalux.itch.io/spritesheet-animation-viewer
When you click for example button SPEED, it works the first time but crashes the app if you click the button again!
Shall I open a GH issue? It's not high priority though.

rrraptor · December 2020

Is there a way to debug macro functions?) Or see the result of applied macro?
