Generator/gas canister script?

Hey, everyone. I am Darkwood Productions, developer of the indie horror game, The Chaser (a spin-off to the 2013 horror game Slender: The Arrival) - now available on GameJolt. I need help editing my game's "activate generators" script and adding in a Void that allows the player to use the gas canister GameObject to turn on (change the Point Light from red to green) the generator GameObject. I have the generator code figured out, but, need help with the code for the gas canisters. Here's the Void's code I have so far:

Code (CSharp):

1.  
2.  
3. void GasCanister()
4. {
5.   if (Input.GetMouseButtonDown(0))
6.         {
7.             Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
8.             RaycastHit hit;
9.             if (Physics.Raycast(ray, out hit))
10. {
11.             if(hit.collider.CompareTag("Gas Canister")
12. {
13.             bool CanisterFound = true;
14.             int canisterIndex = 0;
15.             HasGasCanister = true;
16. }
17.        if(hit.collider.gameObject == GasCanisters[canisterIndex])
18. {
19.             Destroy(GasCanister)
20. }
21. if(!canisterFound)
22. {
23.       Debug.Log("No gas canister found in array")
24. }
25. else
26. {
27.       GasCanister[canisterIndex].SetActive(false)
28. }
29.  
30.  

 

.....is this a help request or a poorly-conceived ad campaign?

 

It's a help request, I only mentioned my game thinking someone would remember me from somewhere. Guess not.
lol. I need help adding a feature that allows the player in my game to use a GameObject (i.e. Gas canister) to switch a light from red to green. Can someone please help me? It would be greatly appreciated. Thanks!

 

When are you calling the function GasCanister()? Because you're not listening for the MouseButton clicks otherwise.... Would you not be better off moving this to the Update() function?
