My calculation won't give me floats.
using UnityEngine;
public class AiRaycast : MonoBehaviour
{
public GameObject player;
public int SpotRayCount = 12, SpotRayLenght = 10, SpotAngle = 90;
void Update ()
{
float rot = -((SpotAngle/ SpotRayCount) * (SpotRayCount/2));
print((SpotAngle / SpotRayCount));
print((SpotRayCount / 2));
for (int i = 1; i <= SpotRayCount; i++)
{
print(rot);
Debug.DrawRay(transform.position, Quaternion.AngleAxis(rot, transform.up) * transform.right * SpotRayLenght, Color.blue);
rot += (SpotAngle / SpotRayCount);
}
}
}
90/12 should equal 7.5 but it prints 7, why is this?
Best Answer
If there are only integers on the right side of the equal sign, the compiler will perform a division of integers.
You need to cast at least one INT to FLOAT to get a float divison.
float f = (float)SpotAngle / SpotRayCount;
