how do i enable and disable specific components on a gameobject with a script?

I tried to disable script the same way script.enable = false, but it just clear checkbox and script continue work like before. Is this a unity bug?

By design, only certain things are disabled in a disabled script. Post as a new question 1) your script, and 2) what you are trying to accomplish with disabling.

These type of questions should be posted as a separate question rather than commented on a 5 year old post. But to answer your question: You'll need to put the SimpleJSON library into your project in order for it to work.

In order to be able to "disable" something, it generally must derive from Behaviour. (Renderer is a notable exception). If you see a checkbox in the Inspector, you can enable or disable it. There are a bunch of shortcuts. For those that have a checkbox, you can do it like this:

camera.enabled = false;

For other behaviours, like your own scripts, you can do it like this, in UnityScript:

GetComponent(MyScript).enabled = false;

or in C#:

GetComponent<MyScript>().enabled = true;

this isn't working. i put it in, but it comes up with 'unknown identifier. 'scriptname' ... how do i put it in?

don't worry, got it working- how can i use this in a script on another gameobject to find a component on another gameobject and enable it?

That's a different question! You really should not ask another question in a comment, but this is covered at the beginning of the manual, so have a link. http://unity3d.com/support/documentation/ScriptReference/index.Accessing_Other_Components.html

Way to disable all scripts on object (C#):

MonoBehaviour[] scriptComponents = someObject.GetComponents<MonoBehaviour>();	
foreach(MonoBehaviour script in scriptComponents) {
    script.enabled = false;
}

My script says Assets/_Scripts/EnterExit.js(24,71): BCE0019: ‘enabled’ is not a member of ‘UnityEngine.Component’. please help since I am only a modeler :slight_smile:

That's because GetComponent() returns variable of type Component. You need to cast it. Try this (substitute SphereCollider with your type of component): var mySphereCollider : SphereCollider; mySphereCollider = someObject.GetComponent("SphereCollider") as SphereCollider; SphereCollider.enabled = false; or this: someObject.GetComponent().enabled = false;

Thanks unfox this helped me with something that was bugging me all day. Even answered a question of mine. Here's my little example based off your code: var SSAOComponentVar : SSAOEffect; function Start () { SSAOComponentVar = gameObject.GetComponent("SSAOEffect"); SSAOComponentVar.enabled = false; }
