Google play service plugin isn’t up to date. I think it needs 7.8 or lower. Use gaming plugin instead

SinisterSoft · July 2018

Make sure you have changed the number for all the plugins that need it - you may have missed one.

antix · July 2018

I've been using 9.2.0 for play services.. try that

I've tried 'Gaming' plugin instead (11.0.4), now player is exported and it works, thx!.

Guys why doesn't Profiler print my results? I've tried to follow code of @SinisterSoft in the article about Rad operator vs math.rad function.
In my console I just get:

Number of tests:	10000000

While I'm expecting something like that:

Number of tests: 10000000
keepInRange1 11.387515123518
keepInRange2 9.3995061483975
keepInRange3 9.056655447766

I've created empty project, all I have in my 'main.lua':

maxIterations@1000000
local randomSeed,random=Core.randomSeed,Core.random
randomSeed(1,1)
 
 
function keepInRange1()
	randomSeed(1,1); local tempStorage,tempNum=0,5
	for i=1,maxIterations do
		tempNum=random(0,-100,100)
		tempStorage=math.min(math.max(1, tempNum), 10)
	end
end
 
 
function keepInRange2()
	randomSeed(1,1); local tempStorage,tempNum=0,5
	for i=1,maxIterations do
		tempNum=random(0,-100,100)
		if tempNum < 1 then tempStorage=1
		elseif tempNum > 10 then tempStorage=10
		else tempStorage=tempNum end
	end
end
 
 
function keepInRange3()
	randomSeed(1,1); local tempStorage,tempNum=0,5
	for i=1,maxIterations do
		tempNum=random(0,-100,100)
		tempStorage=10><(1<>tempNum)
	end
end
 
Core.profilerReset()
Core.profilerStart()
for loop=1,10 do
	keepInRange1()
	keepInRange2()
	keepInRange3()
end
Core.profilerStop()
 
-- print the results of the profiler
result=Core.profilerReport()
print("Number of tests:",maxIterations*10)
 
for k,v in pairs(result) do
	local found=false
 
	for k2,v2 in pairs(v) do
		if found and k2=="time" then print(v1,v2) end
		if k2=="name" and string.sub(v2,1,4)=="test" then v1=v2 found=true end
	end
end

This is because in @Sinistersoft example, the functions under test were called 'testXXX', and he filtered out non matching functions when showing the results. change "test" to "keep" in the last inner loop test

SinisterSoft · July 2018

Yes, I perhaps should have explained that a bit more in the blog post.

If anyone else wants to write some blog posts to help others then please get in touch and I'll add access for you.

SinisterSoft · July 2018

@Apollo14 Can you post the results here, I'd be curious for the results.

P. S. It seems that we should avoid standard math library at all costs. It's almost 3x slower, although code may look cute, compared to other variants.

tempStorage=math.min(math.max(minRange, tempNum), maxRange)

Probably it would be good to add macro operators to replace slow math.sin/math.cos/math.sqrt? (or they can be replaced already?)

Also in some Lua tutorials it is said that localizing math library is helpful, but it didn't make significant difference in this case (neither localizing math. inside function or loop (keepInRange4,keepInRange5), nor localizing it in the beginning of a 'main.lua' file)

Number of tests:	10000000
keepInRange1	10.318172679762
keepInRange2	3.4653780657264
keepInRange3	3.3482103390496
keepInRange4	9.9247725611831
keepInRange5	10.399366280858

function keepInRange1()
	randomSeed(1,1); local tempStorage,tempNum=0,5
	for i=1,maxIterations do
		tempNum=random(0,-100,100)
		tempStorage=math.min(math.max(1, tempNum), 10)
	end
end
 
 
function keepInRange2()
	randomSeed(1,1); local tempStorage,tempNum=0,5
	for i=1,maxIterations do
		tempNum=random(0,-100,100)
		if tempNum < 1 then tempStorage=1
		elseif tempNum > 10 then tempStorage=10
		else tempStorage=tempNum end
	end
end
 
 
function keepInRange3()
	randomSeed(1,1); local tempStorage,tempNum=0,5
	for i=1,maxIterations do
		tempNum=random(0,-100,100)
		tempStorage=10><(1<>tempNum)
	end
end
 
function keepInRange4()
	randomSeed(1,1); local tempStorage,tempNum=0,5
	local mathMin,mathMax=math.min,math.max
	for i=1,maxIterations do
		tempNum=random(0,-100,100)
		tempStorage=mathMin(mathMax(1, tempNum), 10)
	end
end
 
function keepInRange5()
	randomSeed(1,1); local tempStorage,tempNum=0,5
	for i=1,maxIterations do
		local mathMin,mathMax=math.min,math.max
		tempNum=random(0,-100,100)
		tempStorage=mathMin(mathMax(1, tempNum), 10)
	end
end

@Apollo14 I need an email address to add you to blogger, you can pm me it if you want.

SinisterSoft · July 2018

I also updated my code - for some reason I used random number generator 1, when they actually start from 0. There isn't a selection yet so I don't think it matters. I re-ran and had the same results.

guys, help find the cause of the error
in the previous version of gideros there is no such error

Gideros 2018.6.2 there is no mistake

Gideros 2018.6.3 -error ads plugin

hgy29 · August 2018

~~Seems like your AdsAdmob.java file is corrupted around line 432.~~ Just checked, it is fine here with 2018.6.3

EDIT: Looking closer at the error log you have, you are using an outdated version of admob libs

oleg · August 2018

@hgy29 "EDIT: Looking closer at the error log you have, you are using an outdated version of admob libs"

admob libs are not updated with gideros?

how to update them?

hgy29 · August 2018

Specify a higher 'google service' version in the plugin's settings. @SinisterSoft will know better than me.

I have a version 11.0.4 to the greater is not updated

@SinisterSoft
How did you upgrade to 12.0.1?

crutch...

totebo · August 2018

I use Google Play Services 12.0.1 with Admob on Android. I had to alter the Admob plugin slightly for it to work. See this (resolved) issue:

https://github.com/gideros/gideros/issues/394

I guess this will go out in the next Gideros version.

@SinisterSoft @hgy29 does Luasocket work for html5 exported apps? (if we need to connect to NoobHub server)

hgy29 · August 2018

yes and no, it works in that the plugin is available, but you can't do UDP nor TCP in html5, so UDP is just not supported and TCP maps to websocket with luasocket. Basically forget luasocket for HTML5 except if you know your server is websocket capable.

So instead of TCP-based Noobhub server we'll need some websocket-based server?
(like this one? https://github.com/lance-gg/lance )

Or there's built-in functionality in Facebook API for basic PVP multiplayer?

Apollo14 · August 2018

or probably this server is suitable?
https://github.com/gamestdio/colyseus
(it already supports html5 Defold and Construct)

hgy29 · August 2018

Seems to be suitable, yes

how did you upgrade your libraries to 12.0.1 ??

my android studio updates only to 11.0.4

totebo · August 2018

Oh really? I upgraded it like normal, with the built in upgrade tool, to the latest release.

I updated everything yesterday and I have a version 11.0.4 - maximum

Has the LuaSocket plugn changed recently? I had NoobHub working with a login/chat system and it worked just fine with TCP/IP.

I'm testing NoobHub, everything works fine.
(I've connected to @Overtorment 's test VPS, didn't setup my own server yet)

@oleg Sorry I didn't reply earlier, I've been on holiday for a few days.

Google changed the location where the files for google play were grabbed from. You may have an old version of the gradle build file, look at this:

C:\Program Files (x86)\Gideros\Templates\AndroidStudio\Android Template\app

You will see a build.gradle file, edit it (it's a text file) and it should have this section:

repositories {
	maven {
		url "<a href="https://maven.google.com" rel="nofollow">https://maven.google.com</a>"
	}
   flatDir {
       dirs 'libs'
   }
}

That says where the new repository is that google wants (in order to find 12.0.1, etc).

If you don't have that then try downloading and installing 2018.6.3 again as I remember for a few hours there was a version available without that fix (it also showed as 2018.6.3).

Be careful as there is also a build.gradle file in C:\Program Files (x86)\Gideros\Templates\AndroidStudio\Android Template so don't change that one.
