Question by Shrimpalimpa · Dec 10, 2011 at 12:13 AM · javascriptsimple

Set gameobject components to true or false

I am making my first game, a low graphics flight simulator and I have found a way to use a hinge joint motor to give the illusion. I want it so when you press G, the wheels go in. I have a very scant ammount of coding knowledge with Unity, so I can not do it by myself. Anyhoo, I need nothing simple. Just a script that causes areas you can check off to be unchecked/checked.

I wasn't really sure what you wanted. You just want to toggle some variable true/false or a component enabled/disabled? Well, I provide solutions to both.

If you want to toggle flags on/off with buttons:

 var wheels : boolean;
 var lights : boolean;

 // Keep adding more flags if you want...

 function Update() {
     if (Input.GetKeyDown(KeyCode.G)) wheels = !wheels;
     if (Input.GetKeyDown(KeyCode.L)) lights = !lights;

     // Keep adding more toggles if you want...
 }
 

If you want to toggle behaviours on/off with buttons:

 // Drag your components to these variables
 // in the editor inspector.
  
 var wheels : MonoBehaviour;
 var lights : MonoBehaviour;

 // Keep adding more components if you want...

 function Update() {
     if (Input.GetKeyDown(KeyCode.G)) Toggle(wheels);
     if (Input.GetKeyDown(KeyCode.L)) Toggle(lights);

     // Keep adding more toggles if you want...
 }

 function Toggle(component : MonoBehaviour) {
     if (component)
         component.enabled = !component.enabled;
     else
         print("Missing a component!");
 }

What I meant was turning on and off a motor in a hinge joint, but I found a way around that. Thanks anyway.
