you can’t really have multiple trigger functions in unity/c# thid limitations carries over to udon.
trigger functions are things like OnTriggerEnter, Start, Update, etc.
the reason for this is simple, the code doesn’t know which of the two to use.
In general you write a function to do a certain thing, and when you need a function to do more, you just add it to the function.
Sadly udon itself doesn’t allow for function overloading to help manage multiple functions with similar functionality. But in general that would he bad practice to have two functions with the same name do different things.
A way around this however is making a new udon behavior and splitting the new functionality into its own thing. you can have multiple udon behaviors on the same object. Do keep in mind that they’ll be run after each other depending on which one is higher in the list
