//Stop for 1 second
sleep(1)
The above code can stop the process for 1 second, but writing sleep (0.5), for example, will result in an error.
The argument of the sleep function must be specified with ** Uint32 , which means " 32-bit unsigned integer **" ... Anyway, floating point cannot be specified.
Thread.sleep
You can go with this.
// 0.Stop for 5 seconds
Thread.sleep(forTimeInterval: 0.5)
