Hi
In this case you might need to use "Get Mouse Button' Action
use a variable in Store Result.
Then use 'Bool Test' Action.
Place the Variable that you stored from above in the Bool Variable.
On 'IS True' place your 'Tap' event
Also turn on Every Frame.
You might also want to use a 'Finished event' on the tween.
If you want that the tween gets interrupted, then you should ignore the above and do this :
On State 2 add the action 'Get Mouse Button Up' and place an event on it, to go back to state 1
if the tween is moving something and it needs to go back to the initiative position,
Then instead of going back to state 1 directly, place a new state in between and use "Set Position" to place back to the previous position.
