How to check if an object is in the players view?
Hey, Can anyone please tell me how to check if an object, and by extension its children, are within the player's view? Thanks.
Well, to see if it is within view of any camera, you can check renderer.isVisible:
if(renderer.isVisible) // camera can see it
if you mean, is it in line of sight of the character, that's a bit more complicated though, you would probably use a raycast forward from the character object.. not sure which you mean
i will note that this also works in the editor screen, so you will have to debug.
This seems like exactly what i need, thank you. This would attach to the game object that needs to be detected, correct?
correct.. generally, when you see a lower-case keyword, such as transform.position, gameObject.GetComponent(), or in this case "renderer.isVisible", the "renderer" is a keyword which refers to the Renderer Component on this game object. If I wanted to access it from another script, I could do so via a variable:
var theObject : GameObject = GameObject.Find("SomeObjectName");
if(theObject.renderer.isVisible) etc....
Btw. isVisible and OnBecameVisible / OnBecameInvisible are influenced by ALL cameras. If the object is in view of any camera (the scene-view-camera is also a camera), the object will be declared as visible. So keep that in $$anonymous$$d when you test in the editor.
