I am trying to make a game in unity, and I am new to unity and coding, and I have started making a game, I have made some progress on it but I am having trouble finding some of my answers on youtube and the unity forum, and sometimes when I do, I still can't get things to work. So this is what I'm trying to do.
I have a map and the player is on top of the tower, I want the player to fall and when hitting the ground, dies with it displaying game over, What could I do to make this happen and what script?
So i have this now,
// Ground.cs: Kills players that touch this.collider.
using UnityEngine;
// Attach this to the grass collider
public class Ground : MonoBehaviour {
// Called when another collider hits the grass.
// This is part of Unity!
void OnCollisionEnter(Collision c) {
// Does the other collider have the tag "Player"?
if (c.gameObject.tag == "Player") {
// Yes it does. Destroy the entire gameObject.
Destroy(c.gameObject);
}
}
}
Now, I need to it transition to a game over overlay, which asks me to restart, yes or no.
The resources are out there in regards to learning Unity3D efficiently.
Look at the Unity3D tutorials: https://unity3d.com/learn/tutorials
These tutorials are usually kept up to date in terms of not using deprecated code. Additionally, several of the tutorials will teach you how to set up events like those that you need.
In regards to your immediate question though, look into forming the logic for your game.
You're going to need allow your player gameobject to fall via either gravitational force enacted on a rigidbody or hard-coded physics being applied to the gameobject. Next you will need to determine if the player gameobject has collided with the "floor". If so you will need to trigger an event to destroy the player gameobject, then display a GUI Text that says Game Over.
Look around more at tutorials and get better acquianted with Unity. Over time, you'll learn how to make things happen. If you have more questions, feel free to ask.
Answer to you update:
If your code is functioning correctly and your destroying your gameobject correctly, then awesome! You're learning fast!
The next step could be:
Create a Canvas, create a gui panel, create a gui text
That gui text object can have your Game Over Text
Now, create a button that you will utilize as the restart button
You can have the button call a function which utilizes SceneManager.LoadScene to reload the scene. Look here for an example: http://answers.unity3d.com/questions/1109497/unity-53-how-to-load-current-level.html
Next, Disable the panel as you will not need it until your player dies.
When your player collides with the ground you will destroy the player gameobject and set the panel you created to active. (you can trigger these actions via a listener in code or via the button component in the inspector).

I have been working with Unity 2020.3 LTS, the Windows XR Plugin, and the amazing MRTK 2.7.0 to port an existing application to HoloLens 2.
In this application I have a scene with several GameObjects in it and I need to detect whether a hand touches a GameObject (either with the indexfingertip near interaction or the pinch gesture far interaction). The important part here is that this detection needs to happen in a central script in the scene (i.e. maybe have the hand as an object in the code) and not from the view of the touched Gameobject itself.
I have successfully implemented the latter using this example with the two code examples below on that page, but the touched GameObject itself firing events via a listener does not work well with my use case. I need to detect the touch from the hand's perspective, so to speak.
I have searched the web and the Microsoft MRTK documentation several times for this and unfortunately I could not find anything remotely helpful. For head-gaze the documentation has a super simple code example that works beautifully: Head-gaze in Unity. I need the exact same thing for detecting when a hand touches a GameObject.
Eventually I will also need the same thing for eye-tracking when looking at a GameObject, but I have not looked into this yet and right now the hand interaction is giving me headaches. I hope someone can help me with this. Thanks in advance :).
but the touched GameObject itself firing events via a listener does not work well with my use case.
Why does the event not work? Could you provide more detail about it?
In addition to NearInteractionTouchable, have you tried the Interactable component? It's usually used to attach to the touched Game Object and will fire the event receiver when catching input actions. In the event receiver (in the Component UI), you can add any function attached to any object as the listener, such as a central script in the scene. It should be an effortless way can meet your request. For more information please see: Event
After some additional fiddling around I was able to get it to work the way I want/need to with the Touch Code Example. The solution was to create an empty GameObject variable in the code of the central script that is continuously checked whether it is null or not. The touch on the GameObject itself then binds itself to that checked GameObject variable as long as it is touched and sets it back to null once it is not touched anymore. This allows the central script to work with the touched GameObject as long as it is touched.
void Start()
{
centralScript = GameObject.Find("Scripts").GetComponent<CentralScript>();
NearInteractionTouchableVolume touchable = gameObject.AddComponent<NearInteractionTouchableVolume>();
touchable.EventsToReceive = TouchableEventType.Pointer;
pointerHandler = gameObject.AddComponent<PointerHandler>();
pointerHandler.OnPointerDown.AddListener((e) =>
{
centralScript.handTouchGameObject = gameObject;
});
pointerHandler.OnPointerUp.AddListener((e) =>
{
centralScript.handTouchGameObject = null;
});
}
Currently trying to make a multiplayer snake game, I have never made a multiplayer game before. I am having a very strange issue where whenever I add the NetworkIdentity component to my 'Snake' game object, it becomes invisible, but is still there. The game is still functional; you just can't see the snake.
I have two pictures attached, one is the game with the NetworkIdentity component, one is the game without it. Thank you for the help.
Without component
With component
A) your image labels seem to be flipped .. exchange the Without and With ;)
and B) Afaik this is the expected behavior for any GameObject with a NetworkIdentity as long as you are not connected to any network yet. It will get enabled once you host or join a session.
You probably would rather convert this into the player prefab though and not have it in your scene from the beginning but rather let the NetworkManager automatically spawn it for every player in the session including yourself.
I am trying to understand this link which, I believe, is supposed to create a particle where you left-click your mouse. Am I correct?
I have attached the script to an empty game object, so it runs when I run my Unity project. I added a new Particle System game object and dragged it onto the public field of the inspector. Is this the right way of doing it, or should I assign something else to the public variable?
The particle system starts firing up as soon as I run the project, so how do I stop that and then make it begin when and where I have clicked my mouse curser?
public GameObject particle;
if ( Input.GetButtonDown("Fire1") )
{
Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
if ( Physics.Raycast(ray) )
Instantiate(particle, transform.position, transform.rotation);
Debug.Log(Input.mousePosition.x);
}
You should either turn off looping in the particle system or Stop() or Pause() it on Awake() in your script and Play() when clicking the fire button.
Check this page: http://docs.unity3d.com/ScriptReference/ParticleSystem.html
The sample that you have provided doesn't take a particle system, but some 'projectile' prefab, it basically spawns the prefab instance when you click mouse button. It is just an example of very very basic shooting mechanic. I believe that naming on that script could have been better. (I believe that this sample was taken from one of Unity's Merry Fragmas videos, they used some kind of particle system in a similar manner, you'll have to configure the particle system to burst a bunch of particles and not loop after that if you want to use it this way)
I'm new to Unity and the is working on a personal project. In the following picture, you can see a blue plane in the middle, I want to use it as a ice plane and there should be no friction when user is walking on it. In another way, if I press 'w', the object should move forward until it hits an object. I know there's a built-in function called physic material, but it works only when the plane is tilt at some angle so that the object will slide down from the top to the bottom, but if the plane is placed in a horizontal level it will not work. Anybody has any suggestions for it, thanks.
Answering from my phone and off the top of my head, but look at using input.getaxisraw() to get your direction data then add forces. use triggers to stop the movement when you reach a trigger on another object. There were some good tutorials on Collisions and triggers on unity tutorials. To elaborate more, you can add colliders to the objects that you want your player object to interact with physically. So for your player object you can add code like:
OnTriggerEnter(collider c) {
// stop movement
}
I am making a game using a combination of Blender and Unity and have hit a wall. I am trying to make it so a lamp flies off of a table and smashes against a wall once the player walks past a certain point in the map.
I am having a hard time with this. Any help is appreciated.
You need to break this up into little parts.
The first part is that once the player walks past a certain point you want to do something. To do this, look at http://docs.unity3d.com/ScriptReference/Collider.OnTriggerEnter.html
An on trigger event will let you run some code when an object collides with another object. In your case, when your player collides with a certain point in the game.
Next, inside that OnTriggerEvent, you want to fire the lamp off the table. To best do this, create a keyframe animation (or whatever you're most comfortable with) that animates the lamp to fly off the table. Lastly, play that animation in the trigger event. http://unity3d.com/learn/tutorials/modules/beginner/animation
To summarize, when the user hits a certain point, play an animation on the lamp.
