Okay , It's not to be rude , but you need to do some tutorials
So , re-cap ...
You see the paddle ? , place it where you want it to snap
Then , click on it 1 time ... You'll see that a lot of stuff appeared on the left ...
The position tab , you see it ? at your left , It should be two numbers separated by a , ... The first value ... Write it down
Now ... the last action you added as a screenshot , The "on any touch ended" , Click on it and change "Touch.X" by the value we wrote down earlier ...
That's it !
Cheers...
