Really need help please/A switch expression of type `float' cannot be converted to an integral type, bool, char, string, enum or nullable type
I trying to make a enemy ai movement but i keep get a error i can't find a way to fix it. using UnityEngine; using System.Collections;
public class Waves : MonoBehaviour {
float aTemp;
float bTemp;
float dTemp;
float cTemp;
float x3Temp;
float x2Temp;
float x1Temp;

float path;
public float Posy = 0f;
public float Posx = 3.9f;
int dirTemp;
void Start () {
nextWave = 2.0f;
}
// Update is called once per frame
void Update () {
if (Time.time > nextWave) {
//random number determines the path equation
path = Mathf.Floor (Random.Range(Posy, Posx));
//random number determines direction of motion
if (Random.Range (0.0f, 1.0f) < 0.5f) {
dirTemp = 1;
}
// if(Random.Range(0.0, 1.0) <0.5)
else {
dirTemp = -1;
}
//else (Random.Range(0.0, 1.0) < 0.5)
}
switch (path) {
case 1:
aTemp = Random.Range (0.02f, 0.1f);
x2Temp = Random.Range (-6.0f, 6.0f);
dTemp = Random.Range (-3.0f, 5.0f);
break;
case 2:

break;
default:
print ("Waves.cs: Update(): path out of range");
break;
}
//switch (path)
// Instantiate the enemy with starting position and path to follow
for (float i = 0; i < 5; i++) {
if (path < 3) {

}// if (path < 3)
else {

}
and having some other error too
Assets/Waves.cs(87,17): error CS0151: A switch expression of type float' cannot be converted to an integral type, bool, char, string, enum or nullable type Assets/Waves.cs(108,23): error CS0266: Cannot implicitly convert type float' to `int'. An explicit conversion exists (are you missing a cast?)
path is a float. You declare it as such on line 15:
float path;
But you're using it in a lot of switch statements to compare to integer values - case 1:, case 2: etc. You can't use float values in switch statements as the error message states, because they're inherently imprecise. So just declare it as an int instead:
int path;
dude it working find now bro i change it to int and and Change $$anonymous$$ath.FloorToInt
Indeed, floats are limited by switch statements. A workaround is to cast it to int, and, since you are using integers on the switch, then use: switch ((int) path) {}. Alternatively, if you wish to work with decimals, use an if/then/else.
