Ok. 4.14 version have 4 interstitial ad nodes many many thanks to epic staff i love unreal.
There is not any documentation about using those nodes.
I decided to write someting about using them.
Only works with android.
Perhaps it helps someone.
First at the begin of the play use load interstitial ad node. Than control it with is interstitial ad node. İf true everything is nice. İf false try again 0.2 second later.
This will load the ad to background and it will be ready for using.
After that at the end of the play or where you want to show ad, use is interstitial ad available. if it is true use show interstitial ad node.
For the last thing go to project settings, under the android tab give an extra permission “com.android.vending.BILLING” and enter your admob ad unit id.
Thanks again to epic staff
And thats all.
i hope it helps.
