Could Unity Update the Raycast tutorial.

Could you guys a unity Update the Raycast tutorial, it is from a version 3 of unity and that does not work with unity 5.

 

We have a tutorial for Raycasts using Unity 5. You can find it here:

 

Thank you very much!

 

Is there a way in unity 5 to raycast.tag == "Tagname" ?


I am trying to do something like this:

Code (CSharp):

1. RaycastHit Hit;
2.         Ray ray = new Ray(transform.position, Vector3.up);
3.         //Debug.DrawLine(transform.position, transform.position + Vector3.up * RayLength, Color.red); // Shows where the raycast is in the inspector
4.         if(Physics.Raycast(ray, out Hit, RayLength))
5.         {
6.             if(Physics.Raycast(ray, out Hit.collider.gameObject.CompareTag("Rock"), RayLength))
7.             {
8.                 RockInteract();
9.             }
10.         }

 

You are creating two Raycasts when you should only be creating one. Inside the first 'if' block, you can check to see if the object you hit has the tag you are looking for by checking

Code (CSharp):

1. if (Hit.collider.tag.Equals("YourTagHere"))
2. {
3.      //do stuff
4. }

 

Can you point me to this tutorial and tell me what's not working about it?

This is the code that was given

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class ParachuteOpening : MonoBehaviour {
5.  
6.     public GameObject parachute;
7.     public float parachuteEffectiveness;
8.     public float deploymentHeight;
9.  
10.     private bool deployed;
11.    
12.     void Update ()
13.     {
14.         RaycastHit hit;
15.         Ray landingRay = new Ray(transform.position, Vector3.down);
16.  
17.         if(!deployed)
18.         {
19.             if(Physics.Raycast(landingRay, out hit, deploymentHeight))
20.             {
21.                 if(hit.collider.tag == "Environment")
22.                 {
23.                     DeployParachute();
24.                 }
25.             }
26.         }
27.     }
28.  
29.     void DeployParachute()
30.     {
31.         deployed = true;
32.         rigidbody.drag = parachuteEffectiveness;
33.         parachute.animation.Play("openChute");
34.     }
35.  
36.     void OnCOllisionEnter()
37.     {
38.         parachute.animation.Play("closeChute");
39.     }
40. }
41.  

first of all this happens

after that the code is like this:

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class ParachuteOpening : MonoBehaviour {
5.  
6.     public GameObject parachute;
7.     public float parachuteEffectiveness;
8.     public float deploymentHeight;
9.  
10.     private bool deployed;
11.    
12.     void Update ()
13.     {
14.         RaycastHit hit;
15.         Ray landingRay = new Ray(transform.position, Vector3.down);
16.  
17.         if(!deployed)
18.         {
19.             if(Physics.Raycast(landingRay, out hit, deploymentHeight))
20.             {
21.                 if(hit.collider.tag == "Environment")
22.                 {
23.                     DeployParachute();
24.                 }
25.             }
26.         }
27.     }
28.  
29.     void DeployParachute()
30.     {
31.         deployed = true;
32.         GetComponent<Rigidbody>().drag = parachuteEffectiveness;
33.         parachute.GetComponent<Animation>().Play("openChute");
34.     }
35.  
36.     void OnCOllisionEnter()
37.     {
38.         parachute.GetComponent<Animation>().Play("closeChute");
39.     }
40. }
41.  

all it is that you have to do the API update but other than that it still works

 

Yes, that was created for 3.5

We have this on the list to update, but we don't have it in the schedule.

 

OK thanks for telling me

 

Be aware, however, that the core concepts are still valid.

The old v3.5 code used our deprecated shortcuts:

Code (csharp):

1. rigidbody.drag = parachuteEffectiveness;
2. parachute.animation.Play("openChute");
3. parachute.animation.Play("closeChute");

and the new code simply updates these to:

Code (csharp):

1. GetComponent<Rigidbody>().drag = parachuteEffectiveness;
2. parachute.GetComponent<Animation>().Play("openChute");
3. parachute.GetComponent<Animation>().Play("closeChute");

The simple fix would be to declare the following variables:

Code (csharp):

1. private Rigidbody rb;
2. private Animation anim;

... and add to a Start function:

Code (csharp):

1. rb = GetComponent<Rigidbody>();
2. anim = GetComponent<Animation>();

Then you could use rb and anim directly as references:

Code (csharp):

1. rb.drag = parachuteEffectiveness;
2. parachute.anim.Play("openChute");
3. parachute.anim.Play("closeChute");
