Asteroid disappears for no reason
For my space shooter game I need to make some asteroids move towards the player.
I've created the asteroid, made it rotate and destroy on impact.
But when I add my movement script for it, it simply just disappears when testing the game.
This is my movement script:
using UnityEngine;
using System.Collections;
public class Mover : MonoBehaviour
{
public float speed; //public float tilføjes så værdien kan ændres i selve unity istedet for at være kodebaseret
void Start ()
{
rigidbody.velocity = transform.forward * speed; //transform forward er bevægelsen langt z-aksen.
}
}
Ignore the danish notes, please.
im not familiar with C# but shouldnt you state what "speed" is? so far i only see that you use your float speed in your velocity but i cant see how much that speed is?
I suspect it's just going off screen, unless some other code is killing it. Best bet - pause the game as soon as it runs, find the object in the scene view and see where it's gone!
I found the problem.
It's moving along the z axis, which in my case, is the blue vector in this picture: http://i.imgur.com/hb9DtNw.png
I want to move it along the green vector, but how can I achieve this?
Do I replace the transform.forward with something similar?
yup - that or rotate your object. transform.forward will push it along its own z axis. transform.right will push it along its own x axis. transform.up will push it along its own y axis. Or if you want to work in world space (i.e. ignore the orientation of the object), there's Vector3.up, Vector3.right and Vector3.forwards.
It might be moving off camera when Start() is called? Try logging its position to the console to see what's happening with it, or reducing the speed.

Speed or wrong direction is what I have found to be the first questions to ask oneself since this is a dynamic graphics environment. From 'One who has lost many in play...'
