Variables

Variables can declared using the standard C# notation of type_name variableName (= initializing_expression)?

Just like C#, a variable's lifespan is the block it is declared in and its value is re-evaluated every frame.

Not initializing a variable will implicit assign it to default.

template VariableSample render {

    float a = 10f;
    float x;
    Color r = Color.red;
    var g = Color.green;
    
}

State

A state variable will be initialized once and then its value will be remembered every frame until its parent scope is destroyed.

template StateSample render {

    state float a = 10f;
    state float x;
    state Color r = Color.red;
    state var g = Color.green;
    
}
