Call and member nodes

CollectCoin calls four neighbors in a few lines. Color tells you whether a call stays on this class, reaches another indexed class, or leaves the indexed source roots. Member nodes then show where the values came from and where they go.

Figure 1. CollectCoin reads a guard, then calls the coin, score counter, HUD, and optional audio service.

Call this class

Purpose. Calls a method declared on the graph’s class or one of its base classes. Unqualified calls, this calls, and base calls share the light teal family.

Pin	Direction	Type
exec	Input	exec, impure call only
target	Input	Owning class, when shown
each argument	Input	Declared parameter type
result	Output	Declared return type, when non-void
exec	Output	exec, impure call only

C#

RespawnAtStart();

Guide: Method calls.

Call another class

Purpose. Calls a method declared on another type inside an indexed source folder. It uses dark teal, so a project-owned collaborator stands apart from a framework call.

Pin	Direction	Type
exec	Input	exec, impure call only
target	Input	Indexed class type, unless static
each argument	Input	Declared parameter type
result	Output	Declared return type, when non-void
exec	Output	exec, impure call only

C#

_scoreCounter.AddCoins(CoinsPerPickup);

Guide: Call a neighbor.

Call external

Purpose. Calls code whose declaration is outside the indexed source folders, including Unity APIs, framework APIs, and third-party packages. It uses slate gray.

Pin	Direction	Type
exec	Input	exec, impure call only
target	Input	External declaring type, unless static
each argument	Input	Declared parameter type
result	Output	Declared return type, when non-void
exec	Output	exec, impure call only

C#

_audioSource.PlayOneShot(_coinClip);

Guide: Method calls.

GET pill

Purpose. Reads a field, property, local, this, or static value. The compact pill has no exec pins. It can fan one read into several consumers, and Split Pins can separate those reads visually.

Pin	Direction	Type
target	Input	Owning instance type, for an instance member
value	Output	Declared member or local type

C#

_rules.stompScoreValue

Guide: Get and set.

SET

Purpose. Writes a field, property, or local as a statement. SET is an impure navy card because it changes state and participates in exec flow.

Pin	Direction	Type
exec	Input	exec
target	Input	Owning instance type, for an instance member
value	Input	Declared member type
value	Output	Declared member type, the value just written
exec	Output	exec

C#

IsCompleted = true;

Guide: Get and set.

Assignment

Purpose. Writes a target using ordinary or compound assignment. The assignment family covers local declarations and mutation shapes when the renderer distinguishes them from a plain SET.

Pin	Direction	Type
exec	Input	exec
target	Input	Assignable value type
value	Input	Compatible value type
value	Output	Assigned value type
exec	Output	exec

C#

Score += amount;
