Question by SOIL · Aug 01, 2010 at 08:28 AM · errorsyntax-errorcs8025cs0029

Compile Errors for Script

i get an parsing error on this:

using UnityEngine; using System.Collections;

public class MoveForwardwithMouseClick : MonoBehaviour {

void FixedUpdate() { if (Input.GetAxis("Fire1")) { rigidbody.AddForce(transform.forward rigidbody.velocity 2f); } }

Assets/Scripts/MoveForwardwithMouseClick.cs(11,1): error CS8025: Parsing error

i want to thurst a rigidbody forward to it's z-axis with an upwarding speed by pressing the left mouse button.

I closed the lines and get now other errors:

public class MoveForwardwithMouseClick : MonoBehaviour {

     void FixedUpdate() {
         if (Input.GetAxis("Fire1")) { 
         rigidbody.AddForce(transform.forward * rigidbody.velocity * 2f);
         }   
     }
 }

error CS0029: Cannot implicitly convert type float' tobool'

error CS0019: Operator *' cannot be applied to operands of typeUnityEngine.Vector3' and `UnityEngine.Vector3'

O_O

It would be helpful if you pasted the actual error, since it usually tells you exactly what's wrong. That, or you don't have a closing }, I don't know if you just missed that when you pasted your script in here or not.

I think the missing closing '}' for the class is the error.

Okay, two problems.

First: GetAxis returns a number, and you can't if(number).

if (Input.GetButton("Fire1"))

Second: You can't multiply two vectors together. I think you probably wanted this instead:

rigidbody.AddForce(transform.forward * 2f);

You don't need the velocity at all, since AddForce calculates the Dot Product for you, combining the vectors with physics magic. :)
