GUI.Button delays after I click it

anon_57302326 · September 23, 2009, 3:20pm

I create a button on the screen with GUI.Button and then I use it to create an object. I click it, but then I can’t click it again until the object fades away. The coconuts vanish after so many seconds. Why can I only have one instance of this object at a time?

function OnGUI ()
{if (GUI.Button (Rect (10,10,150,100), "I am a button")){
Coconut = Instantiate(myCoconutPrefab, transform.position, transform.rotation);

How do I make things appear as quickly as I click the button?

There must be something else causing this trouble in your project as that code works just fine for me. I hit the button as quickly as I want and see loads o’ stuff getting instantiated.

Is there more going on? Try it in a bare bones test project (just the code above and a prefab).

Here is all of the code, plus some of the error messages in the log.

//create an exposed variable to which you may drag a rigidbody game object in the inspector
var myCoconutPrefab : Rigidbody;
//the amount of force to use in the launching of the coconut, exposed and therefore adjustable in the inspector
var throwForce : int = 20;
//the audio file variable used when throwing coconuts, stored in this variable for selection in the inspector
var throwClip : AudioClip;
//a static (globally accesible by other scripts) variable set to true/false by the Coconut Switch script
var hitPoint: RaycastHit;

function CC(){
//Create a variable, and in it, store the creation of the rigidbody assigned to myCoconutPrefab, creating it at the position and rotation of the object this script is attached to (the empty game object, ‘thrower’)
var Coconut : Rigidbody = Instantiate(myCoconutPrefab, transform.position, transform.rotation);
//set a velocity for that created rigidbody, in the direction of the Z axis, with the amount assigned to variable ‘throwForce’
Coconut.velocity = transform.TransformDirection(Vector3 (0,0,throwForce));
//ignore collisions between the created object, and the player’s collider (transform.root.collider)

Physics.IgnoreCollision(Coconut.collider, transform.root.collider);
//play the sound file assigned to throwClip just once.
audio.PlayOneShot(throwClip);
}

function OnGUI ()
{ if (GUI.Button (Rect (10,10,150,100), “I am a button”)) {
Coconut = Instantiate(myCoconutPrefab, transform.position, transform.rotation);
//set a velocity for that created rigidbody, in the direction of the Z axis, with the amount assigned to variable ‘throwForce’
Coconut.velocity = transform.TransformDirection(Vector3 (0,0,throwForce));

audio.PlayOneShot(throwClip);
}
}

function Update()
{
if(Input.GetButtonDown(“Fire2”))
{CC();
}

OnGUI();

}
