Press the green flag twice for it to work. A simple and explained Encoding-Decoding Engine made by me. Since cloud variables only support numbers, we cannot directly transmit other characters to the cloud. So, we need to convert these characters to numbers. This is where an encoder-decoder comes in. To use it, click the 'See Inside' button and go into the 'Enc-Dec' sprite. You can remove the 'ask and wait' blocks, and under the When Green Flag Clicked scripts, set the "Characters' variable to all the characters you need. When you do this, make sure you put no spaces in between but at the edge. The space is also required and should be added to the code. Then, put the sprite in your backpack and use it in your projects with credit to me, @LutimBoy. I will be using this in my future project ☁Tic-Tac-Toe Cloud Multiplayer.
