In this tutorial I'm going to show you how to take a screenshot, save it and share it with iOS and android's native share function.
For of an example on how this is done, check out my game GATE on iOS and android http://www.mwsGATE.com
Taking a screenshot
In construct, head to the event where you would like to take the screenshot. In GATE I've done it the moment you smash into a wall. Add the action "Snapshot Canvas", this will take the screenshot. It takes a split second to happen so if you want to show the player before it is destroyed then put a 0.1 second wait before you do.
