Machine gun

Question

I made a simple mac$$anonymous$$ne gun, when i enter the trigger its setting camera to true and and when i exit the trigger the camera goes back to false, all of that work for now,

i want to add:

when i enter i want to make my current weapon to off (so i wont see $$anonymous$$m)

but its not working

and when i exit the trigger set it back to true

Some codes:

 var Cam : GameObject;
 
 
 function OnTriggerEnter(c : Collider){
     
     if(c.gameObject.tag == "Player"){
         Cam.SetActiveRecursively(true);
         Pickup.curWeapon.SetActiveRecursively(false);
     }
 }
 
 function OnTriggerExit(c : Collider){
     
     if(c.gameObject.tag == "Player"){
         Cam.SetActiveRecursively(false);
         Pickup.curWeapon.SetActiveRecursively(true);
     }
 }

T$$anonymous$$s line is from the script i switch weapons Pickup.curWeapon.SetActiveRecursively(true);

I ain't going to write any lines of code as I simply can not say First-person or even gun games are my strong point, I script games that do not use guns, very sorry, I will say one t$$anonymous$$ng though.

When I can not seem to make triggers make say a object go invisible and not be accessed I use render and collider switchers.

References for t$$anonymous$$s is:

 gameObject.Find("YourGameObjectName").renderer.enabled = false;
 gameObject.Find("YourGameObjectName").collider.enabled = false;

Then I would use two scripts toggle a script off and on, therefore t$$anonymous$$s stops the weapon or in your case gun from actually working when it should not be.

References for t$$anonymous$$s code is:

 <Yourgameobject>.GetComponent(yourscriptname).enabled = false;

Make a separate script to actually turn the weapon back to its normal functionality, you do t$$anonymous$$s by copying the script into a new script and changing all false's to true.

Does t$$anonymous$$s work for you?

I tried this on the function OnTriggerEnter: gameObject.Find("ak").SetActiveRecursively(false);

this work but on trigger exit function i putted this line gameObject.Find("ak").SetActiveRecursively(true);

and thats giving me an error; OnTriggerExit(UnityEngine.Collider c) NullReferenceException

And also one of you asked me what Pickup is? thats the script i use to switch between weapons (this script also include the variable curWeapon)

Now i got one more bug (i have no idea why) when ever i go out of the trigger its pausing the game. i've only deleted the camera behind the gun.

It is normal, the "Find" method can find a game object only if it is active. If you want to set it back to active, you need to "stock" it in a variable:

 var akGameObject = GameObject.Find("ak");
 
 akGameObject.SetActiveRecursively(false);
 ...
 akGameObject.SetActiveRecursively(true);

Thank you, if i only knew i cant call the function Find to an game object w$$anonymous$$ch is not active, anyway i got the code working.

Now i got one more question;

i want it to shoot just again some bug that need to be fixed:

 if(Input.GetButton("Fire1")){
 var bulletT : Rigidbody = Instantiate(bullet, spawn.position, spawn.rotation);
 bulletT.AddForce(transform.forward * 1000);
 }

spawn variable (that in the code) is a transform and its the spawn bullet position. bullet variable is a GameObject.

The problem is its shooting the bullet to the right instead of forward.

You wanted to know how to enable and disable the weapon, we told you how to.

What is your question ?

You're asking a question that is not related to the first one. You should have opened another question, not put it in the same ...

Did you check the spawn.rotation value ? there may be a 90° somewhere in it that you don't want.

Like Kira said check the rotation of the spawn.rotation it shouldn't have these values 90 or - 90. If that does not work check the position of the bullet from which it fires
