Quick questions about Gideros&Lua

keszegh

sounds like a good solution to me

Guys how can we get user's country? For example if he is from Australia, or from UK, etc.

SinisterSoft

Not sure, but you can get the language: osLanguage=application:getLanguage()

antix

Maybe there is a way to get it using gps?

SinisterSoft said:

what is the difference between 'application:getLocale()' and 'application:getLanguage()'?
update: uh, I got it: while getLanguage provides us just "en" string, getLocale provides a little more detailed string "en_US","en_AU",etc.
it looks like getLanguage is pretty much obsolete, isn't it?

I'm testing tnt animation, it's awesome.
Why in my case self:addChild(self.anim) doesn't work? (self.anim isn't shown when I run player)

function bonusCoin:init() self.anim = CTNTAnimator.new(animLoader) self.anim:setAnimation("COIN_ROTATE") self.anim:setLoop(true) self.anim:setSpeed(150) self.anim:addToParent(self) --it works --it doesn't: self:addChild(self.anim)

hi,
is there a way to achieve negative blend mode with setBlendMode function?
that is, i want that an object has inverse color of what lies below it (like the crosshair cursor set by application:set("cursor","cross") behaves).

keszegh

let me up my question about how to achieve negative blend mode.

SinisterSoft

You can have a source and destination setting so not sure:

@hgy29 may know...

@SinisterSoft , i've looked into those but i do not really understand what they mean. i tried some random combinations without success.

SinisterSoft

Same here!

oleg

local topTex = Texture.new("d4.png",true) local btmTex = Texture.new("d3.png",true)   lh @ 10 -- label height   local w = (application:getDeviceWidth() - lh) / 11 local h = (application:getDeviceHeight() - lh) / 11 local s = math.min(w, h)   for x = 1, 11 do for y = 1, 11 do local top = Pixel.new(topTex, s, s) local btm = Pixel.new(btmTex, s, s) stage:addChild(btm) btm:addChild(top) btm:setBlendMode(x, y) btm:setPosition(lh + s * (x-1), lh + s * (y-1)) end end   local t = {} for k,v in pairs(Sprite) do if tonumber(v) == v then t[v] = k end end   for n = 1, 11 do local label = TextField.new(nil, t[n], "|") label:setX(lh + (n-1) * s + 2) label:setY(1) label:setClip(0, 0, s - 2, lh) stage:addChild(label) local line = Pixel.new(0x666666, 1, 1, lh + 11*s) line:setX(lh + n * s) stage:addChild(line) end   for n = 1, 11 do local label = TextField.new(nil, t[n], "|") label:setY(lh + (n-0) * s - 2) label:setX(1) label:setRotation(-90) label:setClip(0, 0, s - 2, lh) stage:addChild(label) local line = Pixel.new(0x666666, 1, lh + 11*s, 1) line:setY(lh + n * s) stage:addChild(line) end

@oleg, thanks, so do you know if there is a combination which does what i need?

oleg

все залежить від того який ефект ти бажаєш, якщо ти хочеш ефект "перекриття" -як в фотошопі, то це приблизно так:

keszegh

thanks, i will check this out soon.

keszegh

@oleg,
setBlendMode(Sprite.ONE_MINUS_SRC_COLOR,Sprite.ONE_MINUS_DST_COLOR)
did not do the job for me.
(it looked like that this is what you suggested, or wasn't it?)

oleg

@keszegh

Run a snipet with your own pictures


local topTex = Texture.new("d4.png",true)
local btmTex = Texture.new("d3.png",true)

and choose the effect you like


***

I suggested:
sprite:setBlendMode(11, 4)

keszegh

well sprite:setBlendMode(11, 4) did not work as a want.
the 'masking' sprite should be white btw?

keszegh

a white masking image and setBlendMode(6, 1) on it does the job, thanks for assistance.

Guys, if admob ad wasn't received by user and we call 'showAd', it will just do nothing or app will crash? Is it safe to call it without checking triggers?
(I see nothing happens on Gideros Player, but I'm not sure if it's still safe after apk compilation)

There are admob ad formats like "Native Advanced"&"Native Advanced Video". Can we call them?
(they're not mentioned in Gideros documentation)

oleg

зараз в адмоб є лише 3 вида оголошень

"Native Advanced"&"Native Advanced Video" - адмоб вже не підтримує

Guys, what is "GSFXR" plugin?
I see that it plays '.sfx' files instead of regular wav/mp3.
Are .sfx files better than wav/mp3? Do we ever need them?

local sfx1 = Sound.new("testfx1.sfx") sfx1:play()

SinisterSoft

Use this tool to create the files:

It makes great 'retro' style sound fx - You will see the sound file is tiny!

Guys, how would you make a round progress bar? Is there a clever simple solution?

hgy29

It is rather easy, use Path2D to draw two 180° arcs for the progress background, another Path2D on top to draw the progress itself (again two arcs of 180°*(progress ratio)), then a textfield covering the whole circle with vertical and horizontal centering enabled for the percentage.

keszegh

is there any way to check if a sprite on a given position is on top of the stage hierarchy? (i'd call it a hitTestPointReally)

hgy29

I think the last parameter of hitTestPoint is what you are after: hitTestPoint(x,y,true)

oleg

del

keszegh

thanks @hgy29 , for me it seems that if there is another sprite above the sprite then hittespoint is still triggered. the 'true' setting only checks mask/clip according to the reference, not 'real visibility'.
