Assigning script to a variable with a variable

Questions & Answers
1

So the title is a bit weird but i didnt know how to call it.

I am working on a FPS game and I am trying to make a simple weaponsystem. Every Player can have a primary and a secondary weapon. I am at the moment trying to write a script to change between the assigned primary/secondary weapons.

So at first I am doing this:

var primary : GameObject;
var secondary : GameObject;

So I have some GUI Buttons that when they get clicked they assign the desired weapon to the variables primary/secondary.

An code example:

function assignump45() {
primary = ump;
}

Now I want to write a function to switch between the primary and secondary weapon.
So I tried this:

function switchtoprimary(){
if(Input.GetKeyDown("2")){

primary.inv(); //makes the primary weapon invisible
secondary.vis(); //makes the primary weapon visible

}
}

Of course I get this error:

BCE0019: ‘inv’ is not a member of ‘UnityEngine.GameObject’.

I know that what I wrote is wrong. So I tried to get the script of the primary/secondary weapons so I can disable/activate them:

var primscipt : umpscript = GameObject.Find(ump).GetComponent(umpscript);

This works BUT I can´t write for every weapon this kind of script because I then I need to write several combinations of switching between the weapons and that isn´t possible because i know there is a better solution…

I can´t do a if clause and then assign the primscript because the variable only would be assigned in the if clause…

What I need is something like this (doesn´t work of course^^).

var primscipt : primaryscriptstring = GameObject.Find(primarystring).GetComponent(primaryscriptstring);

So I could assign the variable primaryscriptstring with “umpscript” for example. the variable primarystring does work in this case

Are there any workarounds? I am pretty desperate at the moment :confused:

I think you’re overthinking this. Why not something simple like

//put all weapon gameobjects in this array
GameObject[] weapons;
//pointer to currently active weapon
int activeWeaponIndex;

void SwitchToWeapon(int newWeaponIndex){
  weapons[activeWeaponIndex].SetActive(false);
  activeWeaponIndex = newWeaponIndex;
 weapons[activeWeaponIndex].SetActive(true);
}

If you need to access more of your weapon’s functionality, make a Weapon instead of a GameObject, then you could do things like weapons*.SomeWeaponFunction();*
