Sure. With a loop, input button, variable play and maybe show picture it can simply be done.
Give me a minute...
EDIT : There are two mostly used type of mashing button QTE.
- The simple type is to satisfy the mashing quota. ex : Reach 10 tap in 2 second. Fail if times run out.
- The struggle type is to struggle for certain duration. ex : Keep tapping button for 10 second. Fail if you stop for 0.5 second.
This one is the basic event for the simple type.
Note that I put script
Input.isTriggered('ok') as the condition to avoid player holding the button.
* Including animated pic may involve the use of second page event.
* Including the use of bar may involve the use of plugin.
