Super beginner: how do I have 1 script react to data from another?

I'm brand new to Unity and have run across a problem where I need 1 script in the game to react to a variable taken from another. For the specifics, I'm making a 2D game that includes a point where the player falls down a tower and you steer him on the way down. The problem is that his speed is partially determined by his angle (he has a parachute and is able to angle up to slow down a bit). Instead of having him move I have a spawner below him sending obstacles for him to dodge. This means I need the spawned prefabs to know the player's current angle so I can use it to determine their speed. I already save the player's angle as a public variable but I don't know how to call on it from the other script. I thought this would be an easy thing to find an answer to but I've watched several tutorials and haven't found it.


Any help would be appreciated. Thank you!

 

If I understand what you are trying to make, there are number of ways to do it. Here is a way where I tried to make it according to your way of thinking:

This is script attached to player object (PlayerObject.cs), that simply updates position and rotation of it in every frame, in two public variables:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class PlayerObject : MonoBehaviour
6. {
7.     public Vector3 playerObjectPos;
8.     public Quaternion playerObjectRot;
9.  
10.     void Update()
11.     {
12.         playerObjectPos = transform.position;
13.         playerObjectRot = transform.rotation;
14.     }
15. }

And this is script attached to spawner-of-obstacles object in the scene (ObstacleSpawner.cs):

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class ObstacleSpawner : MonoBehaviour
6. {
7.     public float obstacleSpawnDelay = 1.0f;
8.  
9.     private GameObject obstacle;
10.     private Vector3 obstacleObjectPos;
11.     private Quaternion obstacleObjectRot;
12.     private float obstacleSpawnTime = 0.0f;
13.  
14.     void Start()
15.     {
16.         obstacle = Resources.Load<GameObject>("Obstacle");
17.  
18.         obstacleSpawnTime = obstacleSpawnDelay;
19.     }
20.     void Update()
21.     {
22.         if(obstacleSpawnTime <= 0.0f)
23.         {
24.             PlayerObject playerObj =
25.                 GameObject.Find("Player").GetComponent<PlayerObject>();
26.             if(playerObj != null)
27.             {
28.                 obstacleObjectPos = new Vector3(
29.                     playerObj.playerObjectPos.x,
30.                     playerObj.playerObjectPos.y - 50.0f,
31.                     playerObj.playerObjectPos.z);
32.                 obstacleObjectRot = playerObj.playerObjectRot;
33.             }
34.  
35.             Instantiate(obstacle, obstacleObjectPos, obstacleObjectRot);
36.             obstacleSpawnTime = obstacleSpawnDelay;
37.         }
38.         else
39.         {
40.             obstacleSpawnTime -= Time.deltaTime;
41.         }
42.     }
43. }

Regarding ObstacleSpawner.cs script, I went with simply finding the player's object in the scene and grabbing its PlayerObject component (PlayerObject.cs script that is attached to it):

PlayerObject playerObj = GameObject.Find("Player").GetComponent<PlayerObject>();

From that component (script), I used two of its public variables, playerObjectPos and playerObjectRot, to fill in variables obstacleObjectPos and obstacleObjectRot:

Code (CSharp):

1. obstacleObjectPos = new Vector3(
2.     playerObj.playerObjectPos.x,
3.     playerObj.playerObjectPos.y - 50.0f,
4.     playerObj.playerObjectPos.z);
5. obstacleObjectRot = playerObj.playerObjectRot;

Which I then used to determinate position and rotation of the obstacle that was going to be spawned next:

Instantiate(obstacle, obstacleObjectPos, obstacleObjectRot);

Hope this helps
