Question

hello is there a way to check if a var or number has increased by a specific amount? for example if i want to write code that triggers when a var hp = 1 becomes 15.

2 
signal my_number_is_15  
var hp:int = 1:
    set(value): 
        hp = value
        if hp ==15: 
            my_number_is_15.emit()

This is one of a number of ways to handle this.
A lot depends on how you are structuring your program.
The above code creates a signal that is emitted by the variable hp setter function.
