You can contribute to the API documentation by adding or improving comments directly in the plugin's source code.

Display Name​

Sometimes, the default display name will not be correct. For example, an enum named EMyEnum will have a display name EMy Enum.
In those cases, we can define a custom display name by adding a DisplayName meta specifier to the UE macro:

UCLASS(Blueprintable, meta = (DisplayName = "My Great Actor!"))
class AMyActor : public AActor
{
	...
}

Available for: ✔️ UCLASS ✔️ USTRUCT ✔️ UINTERFACE ✔️ UENUM ✔️ UMETA ✔️ UFUNCTION ✔️ UPROPERTY

Full Description​

The full description is used to describe in details what the class/function/variable is used for.
Markdown syntax can and should be used when necessary.

Add a standard comment above the UE macro:

// Here is the description of the variable.
// *It can be on multiple lines.*
UPROPERTY(BlueprintReadWrite)
int MyVariable;

Available for: ✔️ UCLASS ✔️ USTRUCT ✔️ UINTERFACE ✔️ UENUM ✔️ UMETA ✔️ UFUNCTION ✔️ UPROPERTY

Short Description​

The short description is a one-liner to tell roughly what the class/function/variable is used for.\

Add the ShortTooltip meta specifier to the UE macro.

USTRUCT(BlueprintType, meta = (ShortTooltip = "Just a short one-line description here."))
struct FMyStruct
{
	...
}

Available for: ✔️ UCLASS ✔️ USTRUCT ✔️ UINTERFACE ✔️ UENUM ✔️ UMETA ✔️ UFUNCTION ✔️ UPROPERTY

Function Parameters​

The function parameters,as well as the return value, can get a description too.

Use the Doxygen syntax in the comment:

// This is the full description of the function
// @param SomeActor This is the description for the SomeActor parameter.
// @param SomeValue Description for the SomeValue input.
// @return The description for the return value.
UFUNCTION(BlueprintCallable)
int MyFunction(AActor* SomeActor, int SomeValue)
{
	...
}

Available for: ❌ UCLASS ❌ USTRUCT ❌ UINTERFACE ❌ UENUM ❌ UMETA ✔️ UFUNCTION ❌ UPROPERTY
