Float and Double conversion issues

Questions & Answers

I am getting the error message:

Assets/Code/Player Code/SwordAttack.cs(29,17): error CS0266: Cannot implicitly convert type double' to float’. An explicit conversion exists (are you missing a cast?)

Assets/Code/Player Code/SwordAttack.cs(30,17): error CS0266: Cannot implicitly convert type double' to float’. An explicit conversion exists (are you missing a cast?)

Assets/Code/Player Code/SwordAttack.cs(31,17): error CS0266: Cannot implicitly convert type double' to float’. An explicit conversion exists (are you missing a cast?)

I am not trying to convert anything to double anywhere in my code. I cannot see where it it trying to convert the variable. Any help is greatly appreciated.

using UnityEngine;
using System;

[AddComponentMenu("Player/Sword Attack")]

class SwordAttack : MonoBehaviour{
	//finds camera angle x and y for process
	float basecordinantx;
	float basecordinanty1;
	float basecordinanty;
	float basecordinantz;
		//gets mouse cordinants in aray
	int[] sworddirection;
	//processed mouse cordinants
	int[] swordpath;
	//counts the number in the array
	int arraynum;

	//particles
	public ParticleSystem SwordLine;
	
	
	void Update()
	{
				//if left mouse is clicked
		if (Input.GetMouseButton (0))return;
		float camx = Camera.main.transform.eulerAngles.x;
		float camy = Camera.main.transform.eulerAngles.y;
		basecordinantx = Math.Sin (camy);
		basecordinantz = Math.Sin (camx);
		basecordinanty1 = Math.Cos (camx) + Math.Cos (camy);
		basecordinanty = basecordinanty1 / 2;
		Debug.Log (basecordinantx);
		Debug.Log (basecordinanty);
		Debug.Log (basecordinantz);

		}

The ‘Math’ is a .NET class. Math.Sin() and Math.Cos() both return doubles, and you are assigning the result to a float. The best fix is to use Unity’s ‘Mathf’ class (note the ‘f’ on the end):

 basecordinantx = Mathf.Sin (camy);

Or if there is some reason you really want the ‘Math’ class, you can do:

 basecordinantx = (flaot)Math.Sin (camy);
