How can I check if the condition is positive or negative

[zeido]

Hello friends, I created an ad display bot on BAS, but I want to add a condition to this program. Let the ad continue when the ad appears, and the thread should be terminated when the ad does not appear. Since the ad does not have a specific text, I cannot receive it and provide the condition, how can I do it?

@zeido To test for existence, you must first identify the characteristics of the ad, ANYTHING.
If you don't identify the ad, you can't work with it.
