Increase raycast range

Hi all

I found this script on line and I was wondering how can I increse the raycast. any help would be appreciated! thank you very much!

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class Player : MonoBehaviour {
5.  
6.     public bool drawDebugGizmos = false;
7.     public float timeToMove = 1f;

if(Physics.Raycast(currentMoveRay, outhit, 1f))
Just increase the 1f
Check the scripting documentation on raycast, everything you need to know is in there.
If you want to see the ray, use Debug.DrawRay(currentMoveRay.origin, currentMoveRay.direction * 10f) or however long you want it to be.

 

Hey man. The debug is stil in the script. The point is I tried to increase that but nothing changes.

 

Ah hehe didn't scroll all the way down.
Make some rayLength variables for all your rays so you can test it while running h the code.
And just check the docs then see all possible manners for a ray and at which place length is set

 

Up

 

Check the docs if you are refering to Gizmos.DrawRay

https://docs.unity3d.com/ScriptReference/Gizmos.DrawRay.html

 

Omg I'm reading everything about it but still can't find an answer...seems like a problem so simple to solve -,- plz I'm going mad

 

you've already been given the answer to increasing the distance the raycast uses

 

of course is not working...why should I continue posting if it was working?

If I change to zero i don't have raycasts anymore, but if I set it to 10 for example I have the same result of setting it to 1

 

The third parameter of a raycast (given that shape, lots of shapes for the raycast function...) is the distance the raycast is to check. This is very much a "Q: whats 1+1" "A: 2" thing...

If it's "not working" you're either asking the wrong question (bmb and jister hedged a little on this by mentioning the changes to Debug.DrawRay and Gizmo.DrawRay in case it's "how can I show the ray as being longer", displaying a ray and raycasting work differently and are totally separate etc.), or something is not setup correctly elsewhere (missing collider so a raycast of any length is never going to hit whatever it is etc.).

Given that this is code you've found online and you've not really explained what it is you are trying to do, it might not even be code that is applicable to your purposes
Show us your altered code (maybe you altered it incorrectly, we can't know that unless you show it), explain more specifically how it's not working and what you want it to do etc.

 

gimme 2 sec and I'll post the project.

 

You can find here the project. two scripts are missings from the levelcontroller object but they don't affects the raycast problem...all is working fine in the project but if you want to increase the space between the green cubes ( and this means you have to increase the raycast) you'll have difficulties...let me know plz! and thx for the interest!
