When the Player touch the obstacle I want the Player to flash (appear then disappear a few times) itself (maybe for 2 sec) before appearing as opaque. I want to this animation to indicate the collision and the lost of Player’s life.
There is a custom function for blinking. Go to project manager/Functions and behaviors and click on “search for new extensions”. Then search for Blink and download it.
Then after the download go to the players behaviours and add the Blink behavior. Then go from there…
Hope I helped. (ps. You need a internet connection to download extensions)
