Strange issue with compilation and iOS Simulator

[acavestro]

Hi,
I'm trying to learn HaxeFlixel with the fabulous tutorial on HF website. It compiles without problems on Flash, Windows, Mac and Android.

The first time I tried to compile it for iOS with lime test ios - simulator, I got a strange error message that said something like "Can't find asset/ directory". I googled a bit and I find out a fix that could probably work. I edit my AssetPaths.hx from:

 @:build(flixel.system.FlxAssets.buildFileReferences("assets", true))

to

#if ios
    @:build(flixel.system.FlxAssets.buildFileReferences("../assets", true))
#else
    @:build(flixel.system.FlxAssets.buildFileReferences("assets", true))
#end

I tried again and this time the compilation was successful but when iOS Simulator started and I clicked on "Play", app crashed with this message:

Assets.hx:547: [openfl.Assets] There is no String asset with an ID of      "../assets/assets/data/level_001.oel"

I googled another bit but this time I didn't find a solution.

• XCode 5.1.1 with iOS Simulator 7.1 (with command line tools)
• haxelib and all the packages are update
• lime update ios and xcode compilation failed

Thanks in advance

You don't technically need the AssetPaths macro, it's just for convenience - the string path to the asset will do just fine.

I'm not sure why "assets" as a parameter is causing an error. Is this issue exclusive to the iOS simulator?

Thanks for you answer :)

Well, I've restored AssetPaths to original version and I've tried to compile with "lime test ios": it can't find asset directory again. This is the full log:

macbook:project user$ lime test ios

Unfortunately, I haven't an Apple Developer Certificate, so, even if the compilation succeeds, I won't be able to sign the app, test it in a phone and verify it doesn't crash at runtime.

[modjke]

Aaaaaand it's time for a dirty hax (pun intended).
This trouble has to be settled with Context.resolvePath, but there some crazy stuff going while targeting ios, so where is no other way than using workaround.
Here it is, replace original FlxAssets.hx with it.
https://gist.github.com/modjke/263de43baf224e83056e

[Gama11]

The only change there is this?

#if ios
    directory = "../" + directory;
#end

What about mac builds?

[acavestro]

Well, actually that FlxAssets.hx works! Thanks, you save my life 👍

Mac builds work, I've just tried.

[modjke]

@Gama11
mac builds are fine for me, no issues related to invalid assets paths.
Changes are
#if ios
directory = "../" + directory;
#end

and line 67
kind: FieldType.FVar(macro:String, macro $v{
#if ios
fileRef.value.substr(directory.length)
#else
fileRef.value
#end
}),


[Gama11]

@acavestro Cool, I'm gonna commit these fixes then. Can't test this myself unfortunately.

@modjke Any idea why these are necessary? Especially the substr()-thing seems weird.

[Gama11]

[modjke]

@Gama11
The thing is, it's a dirty way of fixing it, i'm sure there are better fixes for that case.
Typically, you just need Context.reslovePath for any path that get processed within macro,
but for this particular case Context.resolvePath('assets') returns ../../../../assets/ and this screws up
things even more.
So long story short, firstly i add ../ to make a valid path, and then remove first part of path to make valid references in a bundle.
I will try to do it in a less 'hacky' way, when it's done i'll update my gist and post an update here.

[Gama11]

Wondering if @jgranick has any insight on why this is necessary for iOS builds.

[modjke]

@Gama11 @acavestro
Here ya go, gist updated with a less hacky workaround that deals with
current directory issue on ios build.
https://gist.github.com/modjke/263de43baf224e83056e
Also, i highly recommend sticking with the lastest version.

[Gama11]

@modjke Is there any need to conditionalize the Context.resolvePath()-call?

[modjke]

@Gama11 yes, i'm not sure why, but for any other build target Context.resolvePath() returns an invalid path and resulting AssetPaths remains empty.

[Gama11]

Hm, ok... Wanna open a pull request with the improved verison?

[modjke]

@Gama11 Sure, why not, give me a minute or two, i'm kinda new to github :)

[modjke]

@Gama11 i did it #1294
