[SOLVED] How to check if float3 is zero.

Setting rotation on an object when using a Vector3 you can check if it has a zero value via:

Code (CSharp):

1.  
2. var toTarget = PathToFollow.PathObjects[CurrentWayPointID].position - transform.position;
3. if (toTarget != Vector3.zero)  //to avoid the "Look rotation viewing vector is zero" exception
4. {
5.     //etc
6. }

Code (CSharp):

1.  
2. float3 lookVector = autoPosition.destination - autoTranslation.Value;
3.  
4. //The following line gets the error:
5. //Look rotation viewing vector is zero
6. Quaternion rotationLookAt = Quaternion.LookRotation(lookVector);

However, if I attempt to wrap that like the Vector3:
if (lookVector != float3.zero)

I get an editor error: Cannot implicity convert type 'Unity.Mathematics.bool3 to 'bool'

Wait, what? What? Nope, I'm lost. Help please.

 

math.all(lookVector != float3.zero)

 

Use math.all(bool3) or better and much faster - math.bitmask (for bool4)

 

Thank you both very much. Seems like an odd thing to convert the float3 to a bool type... but then I am self taught and there is likely something fundamental I am missing.

Again, thank you very much.

Working example: (for the next person)

Code (CSharp):

1.  
2. float3 lookVector = float3_Destination - float3_CurrentPosition;        
3. if (math.any(lookVector))
4. {
5.   //etc
6. }
7.  

 

math.any(float3.zero) is always false so u can just write if(math.any(lookVecotr))

 

oh, DUH.

Thank you!

Have a wonderful weekend

 

BTW, the first solution:
math.all(lookVector != float3.zero)
is incorrect as it returns false as soon as one component is zero.

 

Since float3 implements System.IEquatable<float3>, i would just write !lookVector.Equals(float3.zero) as it's more readable than playing with bool3 math

 

You may use this:

Code (CSharp):

1. if(!lookVector.Equals(float3.zero))
