Title: How to Determine if an FsmVariable is assigned
Post by: Rebooter on August 23, 2019, 06:13:35 AM

In the script for an action, how do you determine if a variable has been assigned by the user?

Example:

[UIHint(UIHint.Variable)]
public FsmFloat remainingDistance;

I need to know if the user has assigned a variable to the above, or if they have selected 'None'.

Is it 'remainingDistance.IsNone'?

I'm also seeing 'useVariable' and 'usesVariable'. What are these?

Hi.
IsNone is the one to use.

if the variable is required you can also place [RequiredField] above it.

Then it is not necessary to check IsNone.

Code: [Select]

{ UseVariable = true };is used when you want to set default value to none.
for example :

Code: [Select]

float1 = new FsmFloat { UseVariable = true };
