Fixing UE5 C2511 Error: Function Overriding Virtual Function Without ‘override’ Specifier

Why You’re Seeing This Error

You’ve created a function that overrides a virtual function from a parent class, but you haven’t used the ‘override’ keyword to indicate this.

Example Error Message

error C2511: 'void AMyCharacter::Tick(float)': overriding function is missing 'override' specifier

Solution

1. Add the override keyword: When overriding a virtual function, always use the ‘override’ keyword.

// Incorrect
void Tick(float DeltaTime)
{
    // Implementation
}

// Correct
void Tick(float DeltaTime) override
{
    // Implementation
}

2. Verify the function signature: Make sure your function signature exactly matches the one in the parent class.
3. Include the correct header: Ensure you’ve included the header file that defines the parent class.
4. Use the Super call when appropriate: Often you’ll want to call the parent class implementation.

void AMyCharacter::BeginPlay() override
{
    Super::BeginPlay();  // Call parent implementation first
    // Your additional implementation
}
