how to call a function with a gameobject as a argument

Questions & Answers
1

I am currently having problems using a gameobject as an argument in a function.

Here is how I am trying to call the held function from another script.

Backpack.Held(0, gameObject);

below is the function in the Backpack script:

public void Held(int a, GameObject b) {
}

I have tried setting the game object into a variable which did not work. I don’t have to use this method to pass the game object.

for reference my situation is as follows:
I pick up one of many object which has the same script, when picked up I must let another(lets say it is the main) script know which gameobject has been picked up.

I suppose I could create an empty gameobject in the main script and set it as the 'pick up’s game object in the pick up script. however I would like to know if I could achieve this using my first method,(and if the second method would work)

all help is appreciated thanks

@TreyH seems to be right, I haven’t seen the way you call the function.

You need an instance of the Backpack class to call the Held function since it’s not a static method of the class.

If the Backpack class inherits from MonoBehaviour, you must get the component / find the object holding the script :

GetComponent<BackPack>().Held(  0, yourGameObject ) ; // If the component is on the same object as your current script
 FindObjectOfType<BackPack>().Held(  0, yourGameObject ) ; // If the component is on an other gameobject

If the backpack does not inherit from MonoBehaviour :

Backpack pack = new Backpack();
 pack.Held( 0, yourGameObject);
