Gideros 2019.4 released

hgy29hgy29 Maintainer
OK, 2019.4 doesn't bring anything new, but improves 2019.2.1 in a way that makes it more stable.
In addition to various fixes, it comes with improved security (AES 256, anti-backup setting on android), and a way to report crashes to a server for HTML5 exports:


[gfx] add Particles:scaleParticles() API
[core] support aes 192 and 256
[android] Optionaly deny backups
[html5] Improve error handling
[plugins] Add virtualpad


[gfx] Fix particles allocation
[ios] Don't compile metal shaders in debug mode
[plugin/ogg] Ogg plugin wasn't fully compiled by default
[gfx/opengl] More error checking/safe guards

As usual you can get the latest version here:

    [core] support aes 192 and 256
    -what does that mean exactly and how do we use it?
  • hgy29hgy29 Maintainer
    This about AES encryption: https://wiki.giderosmobile.com/index.php/Cryptography.aesEncrypt
    It used to support AES 128 only (16 bytes keys), now 24 and 32 bytes keys are supported too.

  • in this version the TTfonts look a bit weird. It is like they do not adapt to each device's resolution. Is that a bug or it is supposed to be like that? And if it is supposed to be like that how should we use fonts for different device's screens and resolutions?
  • hgy29hgy29 Maintainer
    Hi @dreiko65, as far as know, nothing has changed recently in the way fonts resolution is handled. To which version are you comparing, and what do you see/what did you expect?
  • SinisterSoftSinisterSoft Maintainer
    I haven't noticed any difference in the fonts. @dreiko65 can you post a project somewhere that demonstrates what you mean?

    Is TTFontobject still have the optional filtering parameter, which is the 3rd parameter by defaulkt "false" ? (Anti-alise)

    Maybe need to set it to true and try again:
    local testFont = TTFont.new("fonts/tahoma.ttf", 20, true)
  • Hi everyone, it was my mistake after all. By mistake I loaded a file in which I had some older configurations for fonts. I feel a bit stupid now! Sorry people and thank you for your feedback!

    hello @kinrpg you can find a working example of the virtualpad here:


    Just copy the zip file and open it up in gideros studio.

    Please note that it is not using the newly added feature of gideros but it is using the virtualpad.lua class (included in the zip).

    Quick setup:
    - set up the gfx (included in the zip)
    - init virtualpad:
    -- tnt virtual pad
    local texturevpad = TexturePack.new("gfx/UI/TNTVirtualPad.txt", "gfx/UI/TNTVirtualPad.png", true)
    self.vPad = CTNTVirtualPad.new(self, texturevpad, PAD.STICK_SINGLE, PAD.BUTTONS_ONE, 100, 0)
    self.vPad:setScale(PAD.COMPO_LEFTPAD, 2.75)
    self.vPad:setScale(PAD.COMPO_BUTTON1, 3.5)
    - then the listeners
    self.vPad:addEventListener(PAD.LEFTPAD_EVENT, self.myhero.onVKeyDown, self.myhero)
    self.vPad:addEventListener(PAD.BUTTON1_EVENT, self.myhero.vshoot, self.myhero)
    - then handle the virtualpad event
    function Hero:onVKeyDown(event)
    	self.posx += self.vx * math.cos(event.data.angle)
    	self.posy += self.vy * math.sin(event.data.angle)
    Hope this helps!?

    Thanks for the tip. It's a great job. I asked for an example of the native resource because it is not yet in the documentation anymore to be able to know the native resource.
    Still thanks for the example and tip of the code.

    I'm going to download your recommendation and take the test.
