Hi,
Are you able to show an ad properly already?
If you are not, the actions are available on the
EcosystemWARNING: do not follow the Unit doc when it says you need to download a package from the asset store, Unity 5.3 comes with Unity ads as is, so you don't need anything extra from Unity for ads to work if you are on 5.3
-- use "UnityAdsInitialize" at the beginning of your scene ( use the GameId from the Unity setup on the Cloud inspector)
-- use "UnityAdsShowAd" when you want to show an ad
-- the other "UnityAdsXXX" are for more granular control over ads, and not mandatory for the minimum setup.
If you are already setup, then it's a question of using the action "UnityAdsShowAd" properly, and using the 3 different event you can get when showing an ad:
-- Skipped
-- Success
-- Failed
obviously, you only want to reward your user if this action fires the "Success" event.
Does that make sense?
Let me know if you need more clarification.
Bye,
Jean
