I solve this problem in GDScript by call resize to remove banner from view before show Reward or Interstitial. And after banner ad loaded check to show banner if either Interstitial or Reward not showing.
func _on_admob_ad_loaded():
if interstitialShowing || rewardShowing:
yield(get_tree().create_timer(5.0), "timeout")
_on_admob_ad_loaded()
else:
showBanner()

UIKit view modifications should be made only on the main thread. NSThread's isMainThread can be used to determine if the current thread is the main. If the current thread is not the main, the modifications can be delegated to it via Dispatch dispatch_async
or dispatch_sync_f
, using dispatch_get_main_queue
as the queue.

I was getting this problem too when returning from a RewardAd. I used the code from the examples provided in this repo and the crash seemed to be occurring on the label text update i.e. get_node("CanvasLayer/LblRewarded").set_text("Reward: " + currency + ", " + str(amount))

I wasn't sure how to do any of that within Godot, but the closest thing I could find that seemed in the right ballpark was the call_deferred
method. I wrapped the label text update code (above) in a call_deferred
method and it seems to have fixed it, though I'm not entirely sure why.
Is there a better way to fix this within Godot? I don't understand how we would modify a Godot app using Apple's libraries (unless there are "hooks" to them within the Godot API?).
from godot-admob.
Something like this should work.
#include <Foundation/Foundation.h>
#include <dispatch/dispatch.h>
if (![NSThread isMainThread]) {
dispatch_async(dispatch_get_main_queue(), ^{
[interstitial loadRequest:request];
});
}
else {
[interstitial loadRequest:request];
}

@Shin-NiL Yep, it all works fine when I remove the banner ad. I tested exiting the video early, and allowing it play all the way through to get the reward. Both were fine.
from godot-admob.
This problem isn't just related to reward video. I get exactly the same crash (Multiple locks on web thread not allowed) on Interstitial when used with banner ads even if I switch banner ad off before displaying.
from godot-admob.
@Shin-NiL I try it with different threads but result is same. Maybe we need to try this scenario in native iOS app.
from godot-admob.
@Shin-NiL I taken this crash on production environment for my game and I had to remove interstitial ads. There is no difference between simulator or real devices.
from godot-admob.
@wombatwingdings, resize() call from GodotAdMob class. In code when banner resize it remove from view and load request again.
Here is my GDScript to show rewarded video:
func showRewardVideo():
if admob:
rewardShowing = true
bannerShowing = false
admob.resize()
admob.showRewardedVideo()
from godot-admob.
I not yet try hideBanner(). Because hideBanner is only hidden image of ads but view still remaining. Other solution is implement all ads in ViewController of engine, but it is not following with engine workflow.
from godot-admob.
Doesn't seem like the issue has been solved. I've recreated the same issue with what @yamshing changed.
from godot-admob.
found the answer here
You have to comment this line, I did this in the AdmobIntersertitial.mm and in AdmobRewarded.mm then you have to recompile again for the iOS
Now you can close the add without getting the banner, I have it running on Xcode 11 and Godot 3.1.1
Perhaps it would be better to remove that line from the module and tell the devs to manually call a banner after an Interstitial instead of calling it automatically
from godot-admob.
Which versions of Google Mobile Ads SDK, Xcode and iOS are you using?
Unfortunately I don't have any Apple hardware, so I'm afraid I can't help much here. I hope somebody from the community can help us to maintain this module for iOS.
from godot-admob.
The same thing happens in the iOS simulator.
I saw the source for you, but I am not an iOS developer, so I can not tell you exactly what the problem is.
Compared to the admob sample code, it looks like no problem. But the error still occurs.

I have encountered similar problem, on Android it works fine, but on iOS after terminating Interstitial Ad the application exits. Unfortunately I am not an iOS developer too and I don't own Mac or any iOS device, so debugging iOS apps is pretty hard for me.
Version Info:
Godot 3.0.6
XCode 10.1 (10B61)
Admob SDK 7.36
iPhone 6 (iOS 11.4)
from godot-admob.
Yeah, we need help from any iOS developer from the community to figure out a solution :(
I'll update the README with this "Known Issue".
from godot-admob.
I wrapped the label text update code (above) in a call_deferred method and it seems to have fixed it, though I'm not entirely sure why.
Thank you @gvdb, this is interesting information. Can you guys (@zettyfactory , @vinchi9 , @rolandoislas) try this workaround? If it really works, we can try fix the code.

I tested it a little more this morning, and it still appears to be happening. Seems to be an intermittent issue. By luck I must've had a few instances where it didn't crash last night.
Will investigate more.
from godot-admob.
I can't find any way to fix this within the Godot application.
Do the changes suggested by @rolandoislas need to be implemented in the code of this repo itself?
I've attempted to make changes to AdmobRewarded.mm
using these links as guidance, but my knowledge of the Apple code base is even worse than my knowledge of Godot. I've tried something like this:
if (Thread.isMainThread) { obj->call_deferred("_on_rewarded", [reward.type UTF8String], reward.amount.doubleValue); } else { dispatch_async(dispatch_get_main_queue(), ^{obj->call_deferred("_on_rewarded", [reward.type UTF8String], reward.amount.doubleValue);}); } }
But when I try to recompile the Godot engine source, I get errors I'm not sure how to fix, such as the undeclared identifier Thread
. Trying to figure out how I instantiate a variable for the "current thread" so I can query whether it's the "main thread".
Will keep trying and update if I make any progress.
edit: By the way @Shin-NiL, I have an iPhone 6 running iOS 12 that I can test this on if needed.
from godot-admob.
I think the loading of the ad needs to be done on the main thread. For example, this line. I do not have hardware on hand to test at the moment, but I will in a week.

If you can give an example of the code that I would need to add to that line to get it to run on the main thread, I'm happy to test that on my iPhone now.
from godot-admob.
I've applied the changes suggested by @rolandoislas on this branch https://github.com/Shin-NiL/godot-admob/tree/issue_53
Can any of you with access to Mac & iOS test it? I can't even know if it's compiling :(
from godot-admob.
Ok so I changed the loading code for banner ads and reward ads like so:
if (![NSThread isMainThread]) {
dispatch_async(dispatch_get_main_queue(), ^{
[bannerView loadRequest:request];
});
}
else {
[bannerView loadRequest:request];
}
if(!isReal) {
if (![NSThread isMainThread]) {
dispatch_async(dispatch_get_main_queue(), ^{
[[GADRewardBasedVideoAd sharedInstance] loadRequest:[GADRequest request]
withAdUnitID:@"ca-app-pub-3940256099942544/1712485313"];
});
}
else {
[[GADRewardBasedVideoAd sharedInstance] loadRequest:[GADRequest request]
withAdUnitID:@"ca-app-pub-3940256099942544/1712485313"];
}
}
else {
if (![NSThread isMainThread]) {
dispatch_async(dispatch_get_main_queue(), ^{
[[GADRewardBasedVideoAd sharedInstance] loadRequest:[GADRequest request] withAdUnitID:rewardedId];
});
}
else {
[[GADRewardBasedVideoAd sharedInstance] loadRequest:[GADRequest request] withAdUnitID:rewardedId];
}
}
Then I followed the steps for installing the admob module (i.e. recompiling Godot source etc.). It compiled no problems. The game I've built has a banner ad and a reward ad in it, however the web lock crash still occurs when exiting the reward ad.
edit: I also tried having the "main thread" stuff on the Rewarded ad only, and had the banner loaded as it did previously, and the crash still occurs.
from godot-admob.
@gvdb Well, it's basically what I did. Can you tell me if you don't use banner the app still crash?
Maybe we need to instance the ads on the main thread, not only the loading.
from godot-admob.
@gvdb could you try my new commit https://github.com/Shin-NiL/godot-admob/tree/issue_53? I'm trying to putting everything on the main thread (similar to what happens in the Android code). The code is very ugly, but first we need to know if it works.

getBannerWidth and height should not be in the main thread, reverted. Could you try again, please?
from godot-admob.
Ok, it compiles now, but the crash still occurs.
from godot-admob.
It's really sad :(
from godot-admob.
Are there any changes?
from godot-admob.
@cagdasc nope, seems like there is not so much iOS devs using Godot :(
from godot-admob.
@cagdasc unfortunately nothing we've tried has worked so far ;(
Edit: maybe this is a thing.
from godot-admob.
Please, can someone test this branch? I've changed how the module gets the rootController.
from godot-admob.
@Shin-NiL I have tested your branch. Rebuilt the export templates, but unfortunately, no difference:
Sorry, but thanks for trying!
EDIT: Oh, wait. I'm on wrong branch. Let me retest...
EDIT2: Built and re-testested. Definitely got rootController = [AppDelegate getViewController];
in source. Unfortunately, the above crash still stands :-(
from godot-admob.
Thank you very much for testing @wombatwingdings
I did more changes on that branch, could you, or another person following this topic, please make a new test?
from godot-admob.
@Shin-NiL , glad to be able to help in some small way.
I'm afraid new version crashes in the same place too.
from godot-admob.
Thanks again @wombatwingdings!
It's really weird, because a friend of mine have told me it worked fine but on simulator and using godot 2.1.5. Anyways, I'll merge these changes to master, as it seems to not broke anything.

@kynora for the first time it makes sense. So the conflict seems to be with the banner on screen. Did you try only hideBanner() instead of resize()?
from godot-admob.
Could you guys please test the latest commit from our friend @yamshing? It should finally fix this issue.
from godot-admob.
@Dridia1 Could you test with delay bigger than 0 at
https://github.com/kloder-games/godot-admob/blob/master/admob/ios/src/AdmobRewarded.mm#L83
? If it does nothing tell me more about your environnement ( ios version etc... simulator or real device ?)
from godot-admob.
@yamshing I were using the interstitial ad, so I changed the following line instead:
This works perfect, and I'm running iOS 12.4 on an iPhone X
from godot-admob.
@Dridia1 thanks for your test. I will change the delay and commit the change
from godot-admob.
you should also wrap your bannerEnable method with a
dispatch_async(dispatch_get_main_queue(), ^{
// enable banner
});
so the ui gets updated on the main thread.
from godot-admob.
@canvasbushi thank you for your suggestion I will test this
from godot-admob.
Someone can test?
I tested on #124 , and its working fine!
Ps: I tested on version 3.1.2, the version 3.2.1 i doesnt test yet
from godot-admob.
This issue is fixed on 3.1.2, if someone is still facing this issue, please comment here
from godot-admob.
On 2.1 I continue to get this error. In fact, I have stripped everything from the module except the bare minimum of code required by Google to implement a rewarded ad and still receive the error. The issue must be in the engine itself. I have also tried with both Google Ads Frameworks versions 7.41 and 7.60. Same result.
Edit:
I spoke too soon. Updating to the latest SDK, 7.60 seems to correct the issue. You must alter the link flags to link against the new dependencies required by the SDK. The provided frameworks are XCFramework packages, which are not directly supported by the -framework flag as far as I could tell. I had to add the ios-armv7_arm64 directories under each .xcframework to the link path. I don't know of a better way. If this is the best way, then the link flags in config.py will need to be configured per architecture to include the appropriate subdirectory under the .xcframework directories. This is something I can work on. I expect this will solve #135 also.
from godot-admob.
Godot 3 should now have this issue fixed, as a patch has been merged. The fix has also been picked into the 2.1.7 branch, though at this time it hasn't been officially released. I manually applied the fixes to my own Godot fork.
from godot-admob.
Hey @pchasco , yes, on Godot 3 this issue is fixed, i dont know if 2.1.X still happens.
2.1.X version is still in working by Godot contributors?
