Created page with "{{APIdoc|FunctionCallback Delegate}} Encapsulates a method which executes function logic. {{ns}} == Syntax == <syntaxhighlight lang="C#"> public delegate void FunctionCallba..."

New page

{{APIdoc|FunctionCallback Delegate}}
Encapsulates a method which executes function logic.

{{ns}}

== Syntax ==
<syntaxhighlight lang="C#">
public delegate void FunctionCallback(
FunctionContext context
)
</syntaxhighlight>

=== Parameters ===
; ''context''
: Type: [[Dice/FunctionContext|Dice.FunctionContext]]
: Function context, to be filled in by the delegate.

== Remarks ==
The FunctionCallback delegate is used alongside the [[Dice/DiceFunctionAttribute|DiceFunctionAttribute]] and [[Dice/FunctionRegistry/RegisterType|FunctionRegistry.RegisterType]], or with [[Dice/FunctionRegistry/RegisterFunction|FunctionRegistry.RegisterFunction]]. The delegate can gain insight into the context of the function call by examining the passed-in ''context'' object, and it must also modify the ''context'' object's Value and Values. If no delegate in the chain modifies the context's Value or Values, an exception is thrown.
