The Random function is very useful to generate basic random numbers, create random movements, as well as random colors and other more functions. The basic random function is matH.random (); can generate any scales between 0-1, such as 0.0105901374530933 or 0.872525005541986, several other functions can be used to change the resulting numbers, which can be better in yours. Used in the film: math.Round (); Math.ceil (); Math.Floor (); these functions are used to achieve an integer, Math.Round (); is the closest integer in a four-way approach. Math.ceil (); is a closest integer, math.floor (); and math.ceil (); opposite, math.floor (); get a closest integer to combine these functions, you It can be written like this: Math.Round (Math.random ()); this expression can generate a number of 0.0 and 1.0, and then the four rounds will get an integer. The number thus generated is 0 or 1. This expression can be used, such as a hard coin, or TRUE / FALSE instructions in various possible conditions. * 10 is to multiply the decimal number of you generated by 10, and then goes to get an integer: Math.Round (Math.random () * 10); To create a random number between 1 and 10, you can write: Math. CEIL (Math.random () * 10); should be a value of Math.ceil, so it does not generate 0. To create a random number of 5 to 20, you can write Math.Round (Math.random () * 15) 5; that is, if you want to create a random number from X to Y, you can write Math.Round. (Math.random () * (YX)) X; X and Y can be any value, even if the negative number is also.
