The terminal screen does not clear when I press enter. And when I type, it just types over the welcome message.
I’m using Mac OS Catalina, XCode 11.5, and Unreal Editor 4.25.1
Here’s my code. I tried a few variations, but this one is an exact copy of what was done in the lecture.
// Fill out your copyright notice in the Description page of Project Settings.
#include "BullCowCartridge.h"
void UBullCowCartridge::BeginPlay() // When the game starts
{
Super::BeginPlay();
PrintLine("Welcome to Bull Cows!");
PrintLine("Press enter to continue...");
}
void UBullCowCartridge::OnInput(const FString& Input) // When the player hits enter
{
ClearScreen();
}
And here is the output of the terminal in the game:
*edit: As I’ve been playing with it since posting this originally, it seems like my OnInput() method isn’t getting called. Nothing I add to that method seems to run.
I traced it back to the Terminal.cpp file and a function in Terminal called AcceptInputLine(). Here’s the code for the AcceptInputLine:
void UTerminal::AcceptInputLine()
{
Buffer.Emplace(GPrompt + InputLine);
auto Cartridge = GetOwner()->FindComponentByClass<UCartridge>();
if (Cartridge != nullptr)
{
Cartridge->OnInput(InputLine);
}
else {
PrintLine("NULL");
}
InputLine = TEXT("");
I added the else statement to check what was happening, and every time I press enter using the terminal in the game it prints NULL. In my mind, that would mean that Cartridge in the code above is a null pointer, correct? And that’s why my OnInput() function never gets called. But I do not know what to do about it.
