Random numbers
Random numbers are useful for lots of reasons in games—perhaps determining what card the player is dealt or how much damage within a certain range is subtracted from an enemy's health. We will now learn how to generate random numbers to determine the starting location and speed of the bee and the clouds.
Generating random numbers in C++
To generate random numbers, we will need to use some more C++ functions—two more, to be precise. Don't add any code to the game yet. Let's just look at the syntax and the steps that are required with some hypothetical code.
Computers can't genuinely pick random numbers. They can only use algorithms/calculations to pick a number that appears to be random. So that this algorithm doesn't constantly return the same value, we must seed the random number generator. The seed can be any integer number, although it must be a different seed each time you require a unique random number. Look at the...
