How to use GetComponent to modify variables of multiple gameobjects with the same script
I have a gameobject with a script that will control the variables of other gameobjects, how do I modify the variables of the other gameobjects individually? All gameobjects I'm going to modify the variables with are the same script.
I use translator, sorry.
You either assign all the game objects to a list within the script which controls them or you assign a tag to those objects and use
FindGameObjectsWithTag()
in the control script
Helped me a lot, now I can identify each object with the tags. Thank you very much.
in C# you need to make the variables you want to modify public static . Such as if i have a script called ammunition and another script on my gun so that when I shoot it I want to deplete the bullets in the ammunition script. I would have bullets be : public static int bullets;
//ammo script
using UnityEngine;
using System.Collections;
public class ammunition: MonoBehaviour {
public static int bullets = 10;
public int bulletsLeft;//I do this because as a public static you can't see it in the inspector.you don't need this and can delete when you see it's working.but for now I have in my update function bulletsLeft = bullets so I can see that they are indeed going down because the bulletsLeft will show in the inspector an be the same value as bullets
void Update(){
bulletsLeft = bullets;
}
}
//then in my gun script_____________________________________________________
using UnityEngine;
using System.Collections;
public class gun: MonoBehaviour {
MonoBehaviour bullets;// this is the static int variable I want to change
public GameObject ammo; //this is the gameobject with the ammunition script on it;
void Start(){
bullets = ammo.GetComponent<ammunitiion>(); //the variable I want to change = gameobject with script<the script itself>();
}
void Update(){
if (Input.GetKeyDown (KeyCode.Keypad0)) {
ammunition.bullets -=1;// so every time I press keypad 0 the bullet int on my ammunition script goes down by 1
}
}
in C# you need to make the variables you want to modify public static.
No you don't. Do you know what implies the static keyword when declaring a class member? It means that the value of this class member will be shared by every instances of the class. Supposing you have two wepons of the class ammunition, they will share the same ammount of bullets which does not make sense.
$$anonymous$$oreover, you use the static keyword, but you retrieve a class instance using GetComponent. What is the point? If you retrieve the class instance, you don't need the static keyword anymore.
oh, ok. I'm pretty new at this and I had asked a very similar question some time ago and that was the answer i got. or pretty similar anyway. This is not how I handle my shooting scripts it was just an example off the top of my head, but I don't get how if I had two ammo clips with the script "ammunition" on them that they share bullets. I mean if I shoot my gun and that gun is referencing a specific clip with the script ammunition on it how it would effect the script on another game object? I usean ammo$$anonymous$$anager script that keeps track of grenades, flares, pistol bullets, machine gun bullets and C4. Then a script on each that references the ammo$$anonymous$$anager and takes away the particular ammo I used when I used it. If i am holding a pistol i deplete the pistol bullets on fire button pressed, machne gun depletes machine gun bullets etc etc
