Maths & Operators
Maths is used throughout scripting to get many different values, be it the distance between two objects or to calculate an equation.
For example, a variable can be given data from an equation.
variable = 5 + 1;
Although the above example is pretty pointless, as it adds one constant to another to make a constant, and you can just calculate it yourself and use the answer i.e.
variable = 6;
But variables can be calculated using other variables, for example...
varAnswer = var1 + var2;
varAnswer will be equal to the value of var1 plus the value of var2.
There are several operators that can be used in maths...
+ :: Addition - :: Subtraction * :: Multiplication / :: Division % :: Modulus = :: Equals
There are also some more little-known operators such as...
++ :: Increment (+1) -- :: Decrement (-1) += :: Incrementation (requires number) -= :: Decrementation (requires number)
Example of these in use...
var++; //Set var to var + 1 var--; //Set var to var - 1 var += int; //Set var to var + int var -= int; //Set var to var - int
