Resticing variables to whole numbers
Is there any way to make a variable retain its float status while restricting it to whole numbers? I need my variables to be floats but they should also be whole numbers.
Well, the best way to restrict variables to "whole numbers" aka "integers" is by using the "int" parameter type.
Then, if for some reason you really need a float, you probably don't even have to cast to float because casting int to float is not losing precision so it should be an automatic cast ... and I guess UnityScript/JavaScript is pretty loose on these things anyways.
So I guess you can go with:
var myWholeNumberVariable : int;
Normally you'd use a cast to convert between a float and int. So you'd define your variable as a float, but when you need the value as an int youd cast it e.g. x = 5 + (int)myFloat;
There are other methods depending upon your needs to manage the conversions, such as ceiling() or floor(),
Assuming MyNumber is a float, you could do something like this after MyNumber has been assigned a value:
MyNumber = ceil(MyNumber)-1;
I don't know if that syntax is 100% correct and I don't know if what would happen if MyNumber = 4.0000000 before you use ceil. I haven't used this function before.
