how do i convert this float to an int, or avoid it completely? [duplicate]

Question

im trying to make a code that grabs a random number, then takes that number and puts it into a sleep/count down timer, but everytime i try to run the code in unity it tells me i cant convert a float to an int at line 14,39. can someone help me with this? i tried making it grab a randomized number and use that number for a sleep/countdown (not an on-screen count down)

heres my code:

using System.Collections; using System.Collections.Generic; using UnityEngine; public class RandomTimer : MonoBehaviour { public float RadNum = 0f; void Start() { RadNum = Random.Range(1000, 20000); Debug.Log(RadNum); System.Threading.Thread.Sleep(RadNum); } }

Unity defines both float Random.Range(float, float) and int Random.Range(int, int) (see docs.unity3d.com/ScriptReference/Random.Range.html). The compiler would pick the method based on the argument values you supplied. But then you go an assign the int result to a float variable. This is on you. — Jeremy Lakeman

Avoid it completely! You are using the wrong method. For Int, use .Next instead of .Range

Random.Next

Random r = new Random(); int rInt = r.Next(1000, 20000);

Did you try casting?

RadNum = Random.Range(1000, 20000); int x = (int) RadNum;

Of course an int can't represent the exact float value. A 42.2 will be a 42 only and so on.

Better to use Round first if you are casting

@ChrisSchaller I don't think this is important for a random number.

Do not get into the habit of ignoring bad code because it's just a random number If you want int, use Next that gives you ints, explicit casts are red flags on their own. they are an indication that you are doing something unexpected and you might not know why.
