Converting Float to Bool
When I try to do this script it doesn't work but in my mind it seems that it should work it tells me that it cant convert a float into a bool. Please help. This is my script
using UnityEngine;
using System.Collections;
public class PlayerMovement : MonoBehaviour {
public bool isWalking = false;
public float playerSpeed = 5.0f;
// Use this for initialization
void Start () {
}
// Update is called once per frame
void Update () {
if(Input.GetAxis("Horizontal") == true) {
transform.Translate (Vector3.right * Input.GetAxis ("Horizontal") * playerSpeed * Time.deltaTime);
isWalking = true;
}
else {
isWalking = false;
}
}
}
GetAxis returns a numeric value, usually between -1 and 1. C# doesn't treat floats as booleans, which is why you're getting that error.
Perhaps you mean to check if it's equal to zero?
if (Input.GetAxis("Horizontal") != 0f)
Recently needed to handle this with the new Input System. To solve I added an extension method to "float" that will return the float as a bool.
// Extension method
public static bool AsBool(this float value) {
return Mathf.Approximately(Mathf.Min(value, 1), 1);
}
// Usage example (holding shift key)
bool _modifySelection = _pointerSelectModifier.action.ReadValue<float>().AsBool();
// will return "true" if button is currently pressed, the value is >= 1
