Quillscript

// Store class reference in {&ReturnValue}.
$ ^Quillscript.Tools.FindClassByPath /Game/Path/To/Blueprint.Blueprint
$ ^Quillscript.Tools.FindClassByPath /Game/Path/To/Blueprint.Blueprint_C
$ ^Quillscript.Tools.FindClassByPath Module.ClassName

Blueprint

#include "Utils/Tools.h"
...

// Blueprint class.
TObjectPtr<UClass> BlueprintPath{ UTools::FindClassByPath("/Game/Path/To/My/Blueprint.Blueprint") };
TObjectPtr<UClass> ClassPath{ UTools::FindClassByPath("/Game/Path/To/My/Blueprint.Blueprint_C") };

// C++ class.
TObjectPtr<UClass> CppClass{ UTools::FindClassByPath("Module.ClassName") };
TObjectPtr<UClass> CppClassExample{ UTools::FindClassByPath("Engine.Actor") };

---

Get Class Default Object

Get the default object from the given class. This function is useful to expose the Default Object to Blueprints.

Parameters

Class: ref[Class]

Quillscript

// Store class reference in {&ReturnValue}.
$ ^Quillscript.Tools.GetClassDefaultObject {&Class}

Blueprint

C++

#include "Utils/Tools.h"
...

TObjectPtr<UClass> DefaultObject{ UTools::GetClassDefaultObject(Class) };

---

Call Function By Name

Call a Target's function by name and return its Return Value and Outer Parameters.

This is a simplified general usage version of Interpreter.CallFunctionOnTarget() that do not create Quillscript variables and script references.

Parameters

WorldContextObject: ref
Target: ref
FunctionName: name
Parameters: array[string]

Quillscript

// Store class reference in {&ReturnValue}.
$ ^Quillscript.Tools.CallFunctionByName {&Target} MyFunction '("10","true")'

Blueprint

C++

#include "Utils/Tools.h"
...

TMap<FName, FString> OuterParams{
    UTools::CallFunctionByName(
        WorldContextObject,
        Target,
        "MyFunction",
        TArray<FString>({"10", "true"})
    )
};

---

Has Authority

Serves as a shortcut utility designed for use inside static methods that have a WorldContextObject parameter. It allows you to determine whether the current execution context possesses authority, using the GetFirstPlayerController, which is often associated with server or authoritative roles in networked multiplayer games.

While this function provides a convenient way to check authority within static methods, it's important to note that if your function already has access to HasAuthority() through other means, it's advisable to use those methods instead.

Parameters

WorldContextObject: ref

Quillscript

// Store result in {&ReturnValue}.
$ ^Quillscript.Tools.HasAuthority

Blueprint

C++

#include "Utils/Tools.h"
...

// Macro (Only inside functions with a 'WorldContextObject' variable)
if (HAS_AUTHORITY())
{
    // Implementation.
}

// Function call.
if (UTools::HasAuthority(WorldContextObject))
{
    // Implementation.
}

---

Is Module Loaded

Check whether a specific module or plugin is currently loaded within the Unreal Engine project. This function provides a straightforward way to determine if a particular module or plugin is available and active for use in your project.

Parameters

ModuleName: name

Quillscript

// Store result in {&ReturnValue}.
$ ^Quillscript.Tools.IsModuleLoaded ModuleName

Blueprint

C++

#include "Utils/Tools.h"
...

if (UTools::IsModuleLoaded(ModuleName))
{
    // Implementation.
}

---

Generate Random String

Check whether a specific module or plugin is currently loaded within the Unreal Engine project. This function provides a straightforward way to determine if a particular module or plugin is available and active for use in your project.

Parameters

(Omittable) Size: byte = 8
(Omittable) Letters: bool = true
(Omittable) Numbers: bool = true
(Omittable) Symbols: bool = false

Quillscript

// Store result in {&ReturnValue}.
$ ^Quillscript.Tools.GenerateRandomString
$ ^Quillscript.Tools.GenerateRandomString 8 true true true

Blueprint

C++

#include "Utils/Tools.h"
...

FString RandomString{ UTools::GenerateRandomString() };

---

Retrieve Option

Fetch a level transition option by providing the option's key. This function is particularly useful when you need to access specific transition options after a level change, allowing you to retrieve and utilize option values as needed.

Parameters

WorldContextObject: ref
Key: string
Value: string

Quillscript

// Store if level option exists in {$ReturnValue}.
// Store level option value in {&Value}.
$ ^Quillscript.Tools.RetrieveOption MyKey

Blueprint

C++

#include "Utils/Tools.h"
...

FString Key, Value;
FString RandomString{ UTools::RetrieveOption(WorldContextObject, Key, Value) };

---

Sort Strings Alphabetically

C++

#include "Utils/Tools.h"
...

TArray<FString> SortedArray{ UTools::SortStringsAlphabetically(StringsArray) };

---

Register String Table

Register a string table by path. This function is useful when a string table is used by path and never referenced, causing it to not be loaded during runtime.

Parameters

StringTablepPath: name

Quillscript

// Store result in {&ReturnValue}.
$ ^Quillscript.Tools.RegisterStringTable /Game/Folder/MyTable.MyTable

Blueprint
