GetComponent in another script help

Questions & Answers

hi there

I have a problem and i can’t figure out what the problem is.

I have a script with a var that I want to call in another script. I guess my coding is wrong cause i get this error “Assets/script asteroid.js(25,53): BCE0019: ‘lives’ is not a member of ‘UnityEngine.Component’.”

here is the var script called “script player”

var lives : int = 3;

here is the other script called “script asteriod”

function OnTriggerEnter (other : Collider) 
{
	if(other.gameObject.tag == "Player")
	{
		other.GetComponent("script player").lives -= 1;
	}
}

any help will really be appreciated

First of all, does your script actually have a space in its name? I will assume it does not, or at least it should not have.

When you use GetComponent with a string reference Unity does not know what type of object it is and just returns a Component instead. You will have to cast that component into the ScriptPlayer component:

scriptplayer player = other.GetComponent("scriptplayer") as scriptplayer;
player.lives -= 1;

or you could reference the type directly and you will not have to cast it:

//Notice the removal of the " symbols. 
other.GetComponent(scriptplayer).lives -= 1;
