Gideros 2020.7 Released!

SinisterSoft · July 2020

@Hgy29 just made a great release of Gideros...

There is one addition that really need emphasising:
Gideros now has initial support for Lua Shaders! If you code your shaders in Lua then Gideros will automatically translate them to the export platforms native shader language - eg GLSL, HLSL or MTL.

There is an example project to show how easy it is to add effects using Lua.

Help with coding shaders: https://wiki.giderosmobile.com/index.php/Writing_Shaders
Lua specific: https://wiki.giderosmobile.com/index.php/Lua_Shaders

See the full list of changes below.

New features
[library] A library is provided to allow writing shaders in lua, in a platform independent way
[plugin/chroma] Add Chroma plugin by @SinisterSoft
[plugin/share] Add share plugin (Android/iOS)

Improvements
[core/layout] Allow anchoring by floating point amount
[core/layout] Layout now accept cellSpacing parameter
[core/input] Support F1-F12 keys (on QT)

[export/android] Migrate to androidX
[export/android] Update gradle and build tools
[plugin/lfs] Upgrade to 1.6.3, add unicode support for windows, report AHS flags for windows

Fixes
[core/text] Improve tab handling
[core/text] Use the previous separator length and not the current one when computing current line width
[core/text] Fix reporting of minimum size for empty textfields (for layout)
[core/layout] Support zero sized sprites
[core/sprite] hitTestPoint and related functions shouldn't return true if Sprite isn't on screen
[export/uwp] Fix shader uniforms initialization, reduce Win10 SDK minimum version
[export/html5] Support UrlLoader PUT with data
[export/android] Ignore exception on buffer based text input
[plugin/map] Replace deprecated call

I also added a plugin to control Razer Chroma devices - with this you can easily display colour effects and light up keys to specific colours during your game.

The example demo is in the plugin's folder.

The plugin is fully documented here: https://wiki.giderosmobile.com/index.php/Chroma

keszegh · July 2020

Lots of nice stuff, thanks

SinisterSoft · July 2020

The Chroma plugin btw is an example of how anyone (even I managed it

) can add an existing REST API as plugin so it can easily be used through all of the Gideros export platforms.

Thanks for this update

A while ago there was mention of the possibility of Gideros being able to export to iOS without having to open X-Code, just like it does currently for Android without having to open Android Studio. Is this feature still in development or has it been ditched?

MoKaLux · July 2020

thank you for this wonderful update, I need to play with lua shaders

PS: @hgy29 nice picture from your town in the demo

Not completely, but since you need Xcode to upload your app to your phone or to the App Store, it is much less useful than for Android

MobAmuse · July 2020

Nice work! + donated

vitalitymobile · July 2020

@hgy29 Maybe we can use some tools like fastlane.tools for that?
We still need Xcode but almost thing will be done automatically.
Something like this will automatically upload your file and screenshot, descriptions ... to apple:
https://docs.fastlane.tools/actions/upload_to_app_store/

antix · July 2020

@hgy29 darn. Oh well

rrraptor · July 2020

Any example?

Also

local tp = TexturePack.new({"img1.png", "img2.png", "img3.png"})

Crushes the player.

hgy29 · July 2020

@rraptor, quick exemple:

TestClass=Core.class(Object,nil,function(self) print("Destroyed") end)
local test=TestClass.new()
test=nil
collectgarbage()

And thanks for reporting TexturePack issue. I am surprised it crashes, but I will look into it ASAP (in two weeks or so).

TextField:setFont(font) does not work when current font is default font.

Ah, ok

Small suggestion, how about to extend Sprite:isVisible() (or create another method) to be able to get if it actually on screen (if parent (or parent of a parent) is hidden then it will return false)?

local root = Sprite.new()
local sub = {}
 
local prev = root
for i = 1, 4 do 
	local curr = Sprite.new()
	prev:addChild(curr)
	sub[i] = curr
	prev = curr
end
 
root:setVisible(false) --< hide everything
 
print(sub[3]:isVisible()) --> true

After the update, my game that used shaders broke down

The code is the same as in the examples of gideros, only for me it goes as a class:

picShyder = Core.class(Sprite)
 
function picShyder:init(pic,w,h)
 
 
 
local texture = Texture.new(pic)
 
 
local effect = Shader.new("vs","ps",1,
{
{name="g_MVPMatrix",type=Shader.CMATRIX,sys=Shader.SYS_WVP, vertex=true},
{name="g_Color",type=Shader.CFLOAT4,mult=1,sys=Shader.SYS_COLOR},
{name="lightPos",type=Shader.CFLOAT4,mult=1,vertex=false},
{name="g_Texture",type=Shader.CTEXTURE,mult=1,vertex=false}
},
{
{name="POSITION0",type=Shader.DFLOAT,mult=3,slot=0,offset=0},
{name="vColor",type=Shader.DUBYTE,mult=0,slot=1,offset=0},
{name="TEXCOORD0",type=Shader.DFLOAT,mult=2,slot=2,offset=0}
})
 
local mesh = Mesh.new()
--local w=256
--local h=256
 
mesh:setVertexArray(0, 0, w, 0, w, h, 0, h) -- розмір текстури на екрані
mesh:setTextureCoordinateArray(0, 0, w, 0, w, h, 0, h)  -- фактичний розмір текстури
mesh:setIndexArray(1, 2, 3, 1, 3, 4)
mesh:setTexture(texture)
mesh:setShader(effect)
 
self:addChild(mesh)
 
 
 
 
 
local function onEnterFrame(event)
	local x = w/2 * math.cos(event.time * 1.5) + w/2--- радіус * math.cos(event.time * швидкість) + центр
	local y = h/2 * math.sin(event.time * 1.3) + h/2
	effect:setConstant("lightPos", Shader.CFLOAT4, 1, x, y,0,0)
end
 
--effect:setConstant("lightPos", Shader.CFLOAT4, 1, 200, 250,0,0)
stage:addEventListener(Event.ENTER_FRAME, onEnterFrame)
 
end

Do you have any ideas why the code gives an error? In previous versions everything was fine.

ps.glsl is uploading.
vs.glsl is uploading.

Which Platform are you targeting ?

I just run gideros in the player with windows10

UWP doesn't support GLSL shaders - that's why one of the main reasons why Lua shaders have been added. That and the fact that Apple are also moving away from GLSL.

This is not a UWP project, this is a Gideros project.
Shaders from the example 'normalmap' run in the Gideros player, I use the same shaders but call them through the class ..

ps/ The game is released for android

this is probably not a new issue, but i noticed it now:
in html export when TextInputDialog.new() is called with an empty 3rd parameter (that is, no default text in input line) then the input line does not appear at all.

hgy29 · July 2020

@oleg,

You are using

Shader.new("vs","ps",1, ...

whereas in Gideros sample it is

Shader.new("vs","ps",0, ...

. Setting the flag to 1 tells Gideros to use the shader code as-is, without adding a few defines to account for differences between OpenGL (desktop) and OpenGL ES. Your shader is written for GLES, and won't run on desktop with the precision specifiers.

Yes, those icons are not really part of the project structure, so they are not 'consildated'

Thanks helped, I have no idea why I have 1 instead of 0.

bump!

@hgy29 may be the one who can correct this issue, i suspect. thanks

Yes, I can see that the current code would end up doing this! Offending line: https://github.com/gideros/gideros/blob/master/emscripten/gui-js.cpp#L198

keszegh · July 2020

@hgy29 , meanwhile if i put there "" instead of nothing, will that work?

hgy29 · July 2020

No, the code treats null or empty string the same way, unfortunately
