Vector3Int - wrong value for z component

Hi,

Im using Unity3d 2018..2.0f2 Personal Edition.

In my script , I'm calculating the value for Vector3Int ind.

In the Watch window it is clearly showing that the z component value should be 2
but the z component value for ind.z => 1.

I cannot understand why this is happening ?

Please help.

 

Hi,
When i replaced with direct value 2, ind.z = 2;

i think Vector3Int is ignoring the fraction part as in 0 .5 + 1.5 => 0 + 1 => 1

 

Interestingly when i added cp to a new Vector3 with all max values

and then did Vector3Int.RoundToInt(cp) the answer came out right.

 

The whole point of an Integer is that it always continually throws away the fractional part. The fractional part never enters your variables. So yes,

(int) 0.5 = 0, (int)1.5 = 1, (int)0.5 + (int)1.5 = 1

. As you found, if you want an integer answer at the end, then convert to integer ONLY at the end, of a computation.

 

So there is no rounding off if casting float to int.

For some reason i thought rounding off would happen automatically.

Thanks.

 

Check the specifics on

Mathf.Floor, Mathf.Ceil, Mathf.Round

and their

~2Int

varieties. Important to understand how they behave, especially with negative numbers.

 

Thanks for the info. It was worth it.
