Game pause 3
Title: Game Pause 3
Introduction:
In this tutorial, I will show you how to pause a game in the third iteration of the game development series. This will be a useful addition to any game, allowing players to pause and unpause the game at their discretion.
Step 1: Creating a new script
First, we need to create a new script that will handle the game pause functionality. Right-click on the "Scripts" folder in the "Project" window, and select "Create" > "C#" > "New C# Script." Name the script "GamePause" and double-click on it to open in Visual Studio.
Step 2: Declaring variables
Inside the "GamePause" script, we will need to declare a few variables. First, we need a boolean variable called "isPaused" that will be used to determine if the game is currently paused or not. Additionally, we need an integer variable called "pauseKey" to store the key that will trigger the pause functionality.
public bool isPaused;
public int pauseKey;
Step 3: Initializing variables
Now, we need to initialize the "isPaused" variable to false and the "pauseKey" variable to a specific key, such as the "P" key. This will be the key that players need to press to pause the game.
private void Start()
{
isPaused = false;
pauseKey = 'P';
}
Step 4: Handling input events
We need to listen for input events from the player. In the "Update" method of the "GamePause" script, we will check if the "pauseKey" variable is equal to the input value from the keyboard. If they are equal, we will toggle the "isPaused" variable between true and false.
private void Update()
{
if (Input.GetKeyDown(pauseKey))
{
isPaused = !isPaused;
}
}
Step 5: Adding functionality to pause and unpause
Next, we need to add functionality to pause and unpause the game based on the "isPaused" variable. This will involve pausing and unpausing different game elements such as movement, physics, and audio. We can achieve this by creating separate methods called "PauseGame" and "UnpauseGame" inside the "GamePause" script.
public void PauseGame()
{
// Pause game elements here
}
public void UnpauseGame()
{
// Unpause game elements here
}
Inside the "PauseGame" method, you can pause any game elements such as player movement, enemy AI, and physics. Inside the "UnpauseGame" method, you can unpause the same game elements.
Step 6: Attaching the script to an empty game object
Now, we need to attach the "GamePause" script to an empty game object in the scene. You can do this by right-clicking on the "Hierarchy" window, selecting "Create Empty," and then attaching the "GamePause" script to the empty game object.
Step 7: Testing the functionality
Finally, you can test the game pause functionality by pressing the designated key (in our case, the "P" key) while playing the game. The game should pause, and you can unpause it by pressing the same key again.
Conclusion:
In this tutorial, we learned how to add a game pause functionality to our game in the third iteration of the development series. This will allow players to pause and unpause the game at their discretion, improving the overall user experience.
