Resolved private static changes for all generated objects anyway.

Hello there,
I'm trying to generate some objects, and there is a object that should move on the the Y axis, while colliding with the upper or lower object it should change from y = -y etc. It's working as it should, but if another object generates that can move on a lower distance, the first object will also change movement direction with the second object. All objects change directions together. Killed the day making this whole logic without colliders, had other problems. Now trying with them and run in this problem. Any way to fix it? Thanks!
private static float speed = 2.0f;
private static Vector3 moveVector = new Vector3(0, 1, 0);
void Start()
{
}
private void OnTriggerEnter(Collider other)
{
moveVector = moveVector * -1;
}
private void Update()
{
gameObject.transform.Translate(moveVector * speed * Time.deltaTime);
}

 

That's the intended purpose of the

static

keyword. It creates one instance of something shared across the entire application. Changing a

static

variable affects everything that reads from it.

In a nutshell, here's a diagram of how it works. Each object instance shares the value of moveVector because it's static:

If you don't make moveVector static, then it is relative to each object instance, and changing it will only affect the object that it was changed on:



I don't see why you need to make these fields in your class static anyway, so why not just remove the

static

keyword?

 

Thank you very much.
While doing the prototype project from the tutorials here I needed to make a variable static, so it don't change. That's why I made it here the same, but this is a different situation. I understand it now. Thank you for the tip and for the diagram, now it's working perfectly! ^_^
