Speed Pill... Variable referencing and adjusting temporarily

Questions & Answers
1

Hello good people!

In the platform game that I’m creating I have what I’m calling a speed pill which will temporarily boost the speed of the character I have for 5 seconds

What I need to do is on the speed pill item apply a script with an OnTriggerEnter function that adjusts the speed variable in the script called PlayerController to 20 for 5 seconds then it returns to 10. My problem is that I don’t know how to do that, as I don’t know how to refer to a variable in another script as my programming skills aren’t so good.

So far I have the following -

function OnTriggerEnter(otherObj: Collider)
{
    if (otherObj.tag == "Player")
{
		
//here needs to be a function that adjusts the speed      
//variable in PlayerController from 10 to 20 for 5 seconds

}
}

Your help is greatly appreciated, Thank you

You’ll want to use Coroutines to do this.
Unity Coroutines

Coroutines allow you to execute a bit of code and then yield (wait) for an amount of time before continuing execution.
I am not so familiar with unityscript, so this might not compile but it would look something like this

function SpeedUp(float time)
{
    var player = otherObj.GetComponent.<PlayerController>();
    player.speed = 20;
    yield return new WaitForSeconds(time);
    player.speed = 10;
}

Note that if you were to hit a second speed pill before the 5 seconds was up it would not further increase your speed. This may or may not be what you want to happen in this situation.

function Speed(go:GameObject){
go.GetComponent(PlayerController).speed = 20;
yield WaitForSeconds(5f);
go.gameObject.GetComponent(PlayerController).speed = 20;
}
then call it when you get the collision:

function OnTriggerEnter(otherObj: Collider)
{
    if (otherObj.tag == "Player")
{
 
Speed(otherObj.gameObject);
 
}
}

Here is a solution but it isn’t the best way to do it.

function OnTriggerEnter(otherObj: Collider)
{
if (otherObj.tag == “Player”)
{

    PillEffect();
 
    }
}

function PillEffect()
{
 PlayerController.speed = 20;
 yield WaitForSeconds(5); //Causes this fucntion to wait for 5 seconds
 PlayerController.speed = 10;
}

In your PlayerControllerScript put the word Static public in front of var speed; This will allow you access this variable and change it.

static public var speed;
