I am working on a project where I need to move an object relative to the movement of the camera. I need it to be similar to an AR camera, as if the object was staying still even if the phone is moving.
Does anyone have any idea?
I can't use the gyroscope, as it has low compatibility with Android devices. I am trying to use the accelerometer, but it is not working because the object moves right/left when turning the phone like in a diagonal position, and not when staying vertical and rotating.
This is the code I am using:
void Update()
{
transform.Translate(Input.acceleration.x,0 ,0);
}

I'm new to unity and I'm currently working on a portal-like game.
I did the whole teleportation script and it works, but the problem comes that I didn't implement the player camera correction and actually I don't have any ideas how to do it. The concept is that when you're jumping through a portal, the player (or player camera) rotation should be changed to the portal/portal camera rotation from you've come so the final effect is more 'realistic'.
I've tried some lines in teleportation script like player.transform.rotation = portal.transform.rotation but in the end it didn't work and now I end up with nothing, deleting previous scripts and trying to write it all over and over again.
I'll be glad if someone could guide me how to start coding it. Should I do it in onTriggerEnter (when you're jump through portal), or in onTriggerExit? Should the script be attached to a player or to a portals? Should I gather rotation only from camera or from the whole gameobject (portal/player)? I'm posting also couple of screens (with a video how it currently works, and also an entire teleportation script. If I missed something just ask me and I'll post it here.

teleportation script:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class Teleportation : MonoBehaviour {
[SerializeField] private GameObject otherPortal;
[SerializeField] private GameObject player;
void OnTriggerEnter(Collider col) {
if(col.tag == "Player") {
col.transform.position = new Vector3(otherPortal.transform.position.x+1, otherPortal.transform.position.y+1, otherPortal.transform.position.z+1);
Debug.Log("wszedłem w portal");
}
}
void Update() {
}
}
some informations how it is coded right now:
portals are currently in game behind 'the box', i didnt instantiate them anywhere; just changing position on lpm (blue portal) and ppm (orange portal)
portals are sticking to the walls, just like in the original game
portals have a camera attached to it and right now the cameras are static. (offtop: i have a script to move them exactly when player is moving and it quite works but also have some problems, like camera can get too far away from portal and start rendering only that green outer side of the box, and i also dont know how to fix it, so currently i didnt use this script)
the player movement im using is that from unity standard assets (if it somehow matters)
the player have a rigidbody but the portals dont; not sure if i should attach this component to them
teleportation script is attached to the both of portals - the 'otherPortal' variable is moved from inspector, like in orange portal the 'otherPortal' variable is blue portal and the other way
What you did is correct (setting the player rotation to the portal.
You can do it in onTriggerEnter after setting the position, then it should look like
player.transform.rotation = otherPortal.transform.rotation
If you do that, the player will have the same rotation. You already have something that make the camera follow the player, so it is likely that you don't need to set the camera rotation. I don't know how you did your camera follow, so I can't be sure, though. If the camera has not the proper orientation, doing Camera.main.transform.rotation = otherPortal.transform.rotation will do it.
The remaining thing that might be wring, could be that your player (and camera) is not facing the right axis. On your video, I can see that the portal faces the x-axis (the red axis in Unity editor). Check that when going forward, your player has the red axis looking forward.
It is likely that your player has the z-axis (blue) facing forward, which is (by convention) more correct and fits the names Unity uses (z-axis is also called forward-axis)
I would recomand to create the portal object (and all other objects, including the player) so that the forward-axis is the blue one. It might require editing the objects. Anycase, check that the player forward axis is that same as the portal, otherwise setting the rotation won't work
I am looking at developing a game within Unity by using C#
The game will take the gyroscope orientation and rotate accordingly to the direction of which the phone is rotated.
I am curious of how this would work, I understand how I would be able to read and update the gyroscope orientation however I am unsure on how to assign this to a world to rotate. There will be a player on world which will be the next challenge to prevent the player clipping through the world when it is rotated.
Hence the world should rotate around the players current location.
I currently have no code as I am in the process of designing this, however i am unable to get the logic of how to make this work within my head
Thankyou
If I get your objective right, I guess rotating the camera like in a Fist-Person game should be enough, and would be way simpler than rotating the whole world while keeping the player static.
This is how I would go about it, first I wouldn't rotate the world, as that is alot of objects to rotate, but if you really wanted to you could parent all of the world to a single game object, then rotate that object about an axis based off of the players position(See this: https://docs.unity3d.com/ScriptReference/Transform.RotateAround.html).
The simplest way is to attach your main camera to your player(Drag and drop it on your Player Object in your hierchy), then rotate your player.
for an example you can test on your machine without the gyroscrope:
using UnityEngine;
public class rotatorScript: MonoBehaviour {
void Update() {
// Will Rotate based off of left/right arrows
float rotator = -Input.GetAxisRaw("Horizontal");
// Move up or down based off of up/down Arrows
float verticalDirection = Input.GetAxisRaw("Vertical");
// Do the actual movement... using space.self so it is based on the player not the world.
transform.Translate(Vector3.up * verticalDirection * Time.deltaTime * 5f, Space.self);
transform.Rotate(0f,0f,90f * Time.deltaTime * rotator);
}
}
This script would be attached to the player.
I want to move object on touch input in android for unity 2d in c#
I have a pin object and want to move that pin on touching it and moving it as per the touch moves and stop the object where the touch drops it.
also i want to check that pin moved by touch is dropped at certain points on the screen,say for example another box objects where you need to drop the pin object.
I am a newbie to unity platform and is struggling for touch input movement of object.It's and android game.
i donot want to use touchscript from asset store of unity for touch in android.I need a script so that i can attach it to object.
Please help.
You can use OnMouseDrag() because it works on both the editor and mobile so it's easier to test. It works for 3D objects as well as long as they have a collider.
Create a script.
Add the function below to the script and attach it to your sprite.
Make sure to add a collider2d to your sprite otherwise it won't work.
void OnMouseDrag() {
Vector3 mousePosition = new Vector3(Input.mousePosition.x, Input.mousePosition.y, -1*(Camera.main.transform.position.z));
Vector3 objPosition = Camera.main.ScreenToWorldPoint(mousePosition);
transform.position = objPosition; }
I'm trying to make a game using unity and at this point I have created a cube object, a ground object a couple other things. I can make it move by giving it a forward force. I'm basically trying to make a game about a cube that you can navigate through obstacles.
What I want to know is how to get the input like touch input. For example you would use getkey("d") If you wanted to get input from "d" in the keyboard. How would I do the same except for touch input in android?
Use this
Input.GetMouseButtonDown(0)
Example
if(Input.GetMouseButtonDown(0)){
circle.velocity = Vector2.up * jumpForce;
}
https://docs.unity3d.com/ScriptReference/Input.GetTouch.html
You can use this to get a touch object which will give you the screen position, then you can use your cameras position and angle to cast a ray from that point to see if the user is touching the cube.
I`m writing a script, where I control the camera by pushing buttons and by mouse. I need camera always moves forward(where View Frustum is directed ), but it moves only on world axises. How to do it?
You could use
MyCamera.transform.Translate(Vector3.forward);
To move the camera forward, where MyCamera is of course your camera.
