How to set an object into pendulum motion in Sketchware?

How to create a pendulum in Sketchware? Here is a video of how I created a pendulum in Sketchware: Firstly​, in View field create a pendulum in a linear horizontal block, either using an imageview or textview. It should be such that the pendulum lies horizontally in right half of the linear horizontal block. Next, create a new timer, and a new function. Add a new variable t and set it's​ value to 0 in onCreate event. Also set rotation of textview to 90°. Now define the new function in such a way that the linear horizontal rotates in pendulum motion repeatedly. Use the codes as shown in the image below. And then save and run the project. It will show your image or text in pendulum motion.

If you have an app which takes written input and has one or more Edittext widgets being used, you can use a reset button in your app which clears all the inputs in  Edittext  view. The method is very simple. Simply insert a new button in your view field and name it as  reset . Then in it's logic  set all Edittext to blank . The picture​ below shows an example. Now when you click the reset button, it will render all edittext fields blank. 2. How to enable going back or going to previous page in webview? In  webview  if you have not used any code other than  loadurl , the app exits on pressing back button on any webpage. To prevent that, in the logic of the app, use  onBackPressed  event and in that use following code: if WebView ......... canGoBack then       WebView.......... goBack else       Finish Activity On using this code, if there is a webpage history, your app will lead you to a previous page of pressing back
