Grabbing MonoBehavior object from collision
I have a function that does a Raycast and when it hits the correct object, it should do something specific with that object. The problem is that I cannot figure out how to get the object that extends from MonoBehavior.
Here is the code I've been using:
void checkForHit(Vector3 position) {
var ray = Camera.main.ScreenPointToRay(position);
RaycastHit rayHit;
if(Physics.Raycast(ray, out rayHit)) {
if(rayHit.collider.tag == "specificTagToThisObj") {
var monoObj = rayHit.transform.gameObject as MyMonoBehaviour; //This line has an error.
}
}
}
Is this possible to do?
Although c# does have a var keyword, it's probably better to use explicit type declarations. Your line 2 would be better to be written as Ray ray = ... for example. It's possible that your code is a mix of c# and Javascript...
This is 100% C#, not mixed with JavaScript.
I also disagree with explicit typing here. In the C# style guide, they say you should use implicit typing if it is obvious what that variable is. In this case, it should be quite obvious that the variable ray is of the class Ray.
See http://msdn.microsoft.com/en-us/library/ff926074.aspx under Language Guidelines -> Implicitly Typed Local Variables.
MonoBehaviour basically means a script. In code, scripts are usually referred to as Components. So, I suspect you actually want to access a component that is on the hit object. So, you probably want:
Wibble w = rayHit.transform.gameObject.GetComponent<Wibble>();
where Wibble is the name of your script/class.
