Is there a TouchUp check?
Monkey Forums/Monkey Programming/Is there a TouchUp check?

| I did a search for TouchUp but didn't find what I need. I see there is a TouchDown and TouchHit. How can I determine when a TouchUp has occured? |

| I guess you could record whether touch(n) was down on any update and then record a TouchUp on the first update when it is no longer down. Same as drag-release, which I think has been discussed. |

| I quickly knocked up this example to show a way of identifying more touches. If you run the code in htlm5 and click and drag around it will print showing what its recognising. it can detect Down, Moved, Up and Up Inside. Hopefully this should help you implement a function, if you get stuck let me know. The code doesn't check for more than 1 touch so that will need to be considered...
