Forcing Public Integer Variable to be divisible by something.

Unity Engine
1

Hello guys, I need a public integer variable that is Between 1 and 90 and whenever someone changes the variable in the inspector , I want it to change automatically to the nearest integer divisible by 9.

[Range(1,90)]
public int rollingSpeed = 5;

How about setting positive integer variables that are forced to be set 0 or 1 or may be something if they are changed into negative numbers in the inspector.

Depending on what you want to do, I’d just change the range to 0-10 and then multiply rollingSpeed by 9 in your code. This way the value is always valid and you save yourself the validation.

Otherwise, you can use the OnValidate message in your MonoBehaviour scripts. This method will be called when the script is edited in the inspector and allows you to round the value to nearest multiple of 9.

In my experience, OnValidate hasn’t always been very reliable. You’d want to also implement the check in OnEnable to make sure it’s always properly applied.
