We'll continue with the same script. Make a variable named Object.
Add a set () to () block. Change the variable to Object and set the value as 0.
Add a repeat until () block. Drop an () = () block in the condition.
In the first input, add a recognized () count block and select object from the drop-down. In the second input, add the Object variable.
Inside the loop, add a change () by () block from the Variablespalette. Change the variable to Object.
Snap a create clone of () block from the Control palette and select myself from the drop-down. Selecting myself means that you want to clone the same sprite you are writing the script for.
Add a wait () seconds block in the loop. With this, our main script is ready.
