Gideros 2019.12 released

hgy29 · December 2019

Gideros 2019.12 is finally here.

I know some of you have been waiting for it, but it turned out changes have been heavier than expected. We decided to make one more step forward in 3D land with this version, to further explore what Gideros could do: this time Gideros adds support for geometry instancing (on Mesh) and Shadow Mapping (by enabling render targets to capture depth layer) for all platforms, that is OpenGL/GLES (v3 is required for those features), UWP/DX11 and Metal.
Two more demos/exemples have been added to cover these additions.

A few more minor additions, yet useful:
- Path2D:setFillColor now accepts gradients, in the way way Pixel:setColor does.
- Pixel now accepts TextureRegion

See the full list of changes below.

New features

[Core] Allow instanced rendering on Meshes
[plugin] Add fastnoise plugin by @MultiPain

Improvements

[core] Add accuracy and source to geolocation events
[core] Report magnetic X,Y,Z values in Geolocation heading event
[core/gfx] Use GL ES 3/ WebGL 2 is available
[core/Path2D] Allow gradients in setFillColor
[ui/examples] Rework 3D exemples, remove cubemap as it doesn't work anymore
[examples] Add 3D animation
[examples] Add instancing demo
[ios/metal] General improvements and support instancing+depth textures
[html5] Update to emscripten upstream, switch to WASM compltely as a consequence

Fixes

[studio] Fix dependency graph being lost
[studio] Fix newly linked directories leading to file I/O issues
[core/fonts] Fix text layouts positionning, add more options
[uwp] run open url on UI thread
[android] Allow reads from http connections
[android] Possible fix for OpenSl crash (#450, #480)
[android] Only comment out uses-sdk for AAB
[ios/metal] Don't clear error log before displaying
[ios/metal] inline shaders functions shall not be called main: use vmain and fmain instead

As usual, you can get the latest version here:

"[core] Add accuracy and source to geolocation events "

~~@hgy29 -What does it mean?~~

I figured it out myself

keszegh · December 2019

and it's smaller than the previous release, if we continue this way at some point it will be 50mb...
great release, thanks for all who have contributed and put it together.

keszegh · December 2019

is there some additional tutorial/manual for mesh instancing besides the example project?

UPDATE: i'm in particular interested if i can use it in 2d somehow to speed up drawing plethora of meshes.

UPDATE2: the example throws an error:

3dbase/3dshapes.lua:32: attempt to call field 'setSpriteMode' (a nil value)
stack traceback:
3dbase/3dshapes.lua:32: in function 'updateMode'
main.lua:10: in main chunk

UPDATE3: let me post here @hgy29 's solution for this problem:
"If the examples throw an error, it probably means that there are some files from previous gideros version left in InstallDir/Library folder. Remove them all and reinstall "

@hgy29 Why does it give me nil value?

hgy29 · December 2019

No idea, I didn’t test it.

hgy29 · December 2019

Code is here: https://github.com/gideros/gideros/blob/3b03e868b4955b4973fddd9e069c78839cbf2123/luabinding/geolocationbinder.cpp#L165

Is your android player up to date ?

Everything works, it was necessary to update the player

keszegh · December 2019

thanks, @hgy29 , now the example works. it's too complicated for me to see from it if i can use it for 2d purposes though.

PaulH · December 2019

Can't wait to try it out! Thanks!

rrraptor · December 2019

Thank you for your support!)

Btw, I thought that noise plugin will appear on the wiki page, so It can be edited. But it doesnt. So, it should be added manually?

SinisterSoft · December 2019

I've started it here, not too sure on how all the docs are working right now (not been fully following), but at least it's a start... Can someone who knows the plugin/knows the latest way the docs work finish it off?

https://wiki.giderosmobile.com/index.php/FastNoise

MoKaLux · December 2019

I will do it (insha'Allah). Thank you @SinisterSoft for starting it I wasn't sure how to begin. I need to read the doc and test it before so give me some time please.

I am using the latest gideros release and it looks GIGANTIC.

@all thank you very much for this great release.

rrraptor · December 2019

@SinisterSoft can I edit by myself?

SinisterSoft · December 2019

@MoKaLux Thanks.

@rrraptor Have you got a login to the wiki? If not then pm me with an email address and I'll create a login for you (so you have edit abilities).

Yes, I admit it is a bit complex to use currently since the only api that was added is to enable it on Mesh. If you call Mesh:setInstanceCount() to specify a number of instance, the GPU will draw your mesh that number of times instead of just once. This isn’t very useful unless you make a shader that is aware of it and can change vertices positions for each instance.

The example I wrote shows it works, now if we can find specific common use cases we can integrate them into gideros core code.

Thankyou for enabling Pixels to use TextureRegions from TexturePacks, very handy

@hgy29
I found an error in the formula instead of '-y' should be replaced by 'y'

I checked it

	scrX=(minX-maxX)*-1
	scrY=(minY-maxY)*-1
 
 
end
content()

local arr2=Bitmap.new(Texture.new("compass-pointer.png"))
	arr2:setAnchorPoint(0.5,0.5)
	arr2:setPosition(centrX,centrY)

	 magneticHeading = (math.atan2(fx, fy) + math.pi) * (180 / math.pi);
 
	arr2:setRotation(magneticHeading)
end
 
geolocation:addEventListener(Event.HEADING_UPDATE, onHeadingUpdate)
geolocation:startUpdatingHeading(magneticHeading)

Just installed newest version and went to run the 3D Collision example...

3dbase/3dshapes.lua:32: attempt to call field 'setSpriteMode' (a nil value)
stack traceback:
3dbase/3dshapes.lua:32: in function 'updateMode'
main.lua:17: in main chunk

There does not appear to be a setSpriteMode() function inside lightning.lua

EDIT: It appears that 3D-Anim example also suffers from the same issue.

EDIT2: And 3D-Instacing example for the hatrick fail

MoKaLux · December 2019

@antix I don't understand your post. Do you mean the examples you mentioned don't work for you?
If so try this:

I am on windows and before installing the new gideros I manually uninstalled the old one. I had no issue running the examples. For example the 3DAnim example:

antix · December 2019

@MoKaLux I'll give that a try.

Yep that worked. Strange how the installer didn't a) overwrite existing files or b) remove fully the previous installation.

hgy29 · December 2019

I think the issue is that the installer do overwrite previous files, but somehow doesn’t seem to remove anything. I wonder if it runs the uninstaller before installing actually...

SinisterSoft · December 2019

Maybe somewhere in the installer config is a list of folders to empty? if so, that folder may not be on the list.

MobAmuse · December 2019

Nice update! Donation inbound shortly

Thank you for keeping Gideros alive and kicking.

MobAmuse · December 2019

I get this on the new 3D Animation demo when running on Gideros Player that comes with 2019.12...

3dbase/3dshapes.lua:32: attempt to call field 'setSpriteMode' (a nil value)
stack traceback:
3dbase/3dshapes.lua:32: in function 'updateMode'
main.lua:23: in main chunk

MobAmuse · December 2019

Same on the other 3D Instancing demo too pretty much...

3dbase/3dshapes.lua:32: attempt to call field 'setSpriteMode' (a nil value)
stack traceback:
3dbase/3dshapes.lua:32: in function 'updateMode'
main.lua:10: in main chunk

MobAmuse · December 2019

Ah sorry I see others had the problem above also. Will fiddle.

MobAmuse · December 2019

All good now after removing old version and doing fresh install.

MoKaLux · December 2019

I need some help please. Can you still export to html?
I have been trying to export a project to html5 with no luck .
Then I tried a project which I could export to html5 using previous gideros version, and it failed with the new version!?
By failing I mean that it compiles fine but doesn't run on the browsers (firefox, edge, ie11). It is stuck in an infinite loop.
I am on windows 10 and I have these plugins: ads, bump, gaming.
Some debug messages are:

HTML1300: Navigation occurred.
index.html (1,1)
Loading plugin:EP_Mp3.wasm
Instanciating plugin:EP_Mp3.wasm
still waiting on run dependencies:
dependency: gidPlugins
(end of list)
still waiting on run dependencies:
dependency: gidPlugins
(end of list)...

I can compile to windows and android fine.

edit: I use TILED files:
tiled.lua (exclude from execution)
tiled.tmx (don't package)
tiled.tsx (don't package)
edit2: I tried a sample example (fading stars) to html5, doesn't work.
Maybe something is broken

hgy29 · December 2019

For me it works, but it is damn slow. There seem to be an issue with 2019.12 html export.
