Hi! I’m making a classical point&click quest and need to know if some object can be pushed/used/etc. Main camera object script raycasts such objects and stores a reference to them. Player object script has main camera as a public variable and asks it for that reference. And at this point I don’t know how should I proceed further. First, it seems like I cannot use a reference to a reference like this cameraScript.clickedObject.someMethod(). It logs an error for some reason. Second, if I use cameraScript.clickedObject.SendMessage(“someMethod”) I need to know right away if that method is implemented. I thought maybe SendMessage returns true/false for success/failure or some error object can be used but found none in the documentation. Thanks!
Here is how I’ve done it:
if cameraScript.clickedObjectScript != null and cameraScript.clickedObjectScript.GetType().GetMethod(“method”): cameraScript.clickedObjectScript.SendMessage(“method”)
A script per command also works fine if overly complicated in my case. Thanks to everyone!

You can use reflection to discover if a method exists.
Use a
if(gameObject.GetComponent<Pushable>() != null)
and will return true or false if there is any component of that class there.
You don’t need to use a single class for everything, you can create a class and add that property to any go, and is cleaner sometimes.
You can also check a tag, if you put a tag pushable in the go for example.
