Multi-level inheritence (Yuk!), how can I implement my design? [NVM, I'm an idiot...]

Hey all,

Okay, so this is probably more about design than the coding... but I would still love your feedback.

Here's the summary of the issue.

• Each player can have differnet loadouts for their drone.
  
• Some are weapons, some are tools.
  
• Some weapons are physics based, some are field based, some are raycast/energy weapon based. Tool are broken up similarly.

So, what I was thinking of was having a "GearBaseClass" that simply has 2 abstract functions: TriggerDown and TriggerUp.

I then SubBaseClasses which inherit from GearBaseClass for the different weapons (physics, field, energy) and some for the different types of tools.

I will then have subClasses for each specific weapon/tool type. This will inherit further the TriggerDown() and TriggerUp() functions.

This works! XD (Yay, for me!)

However, to reduce the amount of typing and copy/pasting that I do I was going I was hoping to write some functionality into the SubBaseClasses - things like public transform fields for spawn points, public floats for velocity, etc.

But you can't inherit fields.

Okay, so I try to set up some abstract properties instead as in the following code:

Code (CSharp):

1. public class GearPhysicsWeaponBaseClass : GearBaseClass
2. {
3.     public abstract Transform SpawnPos { get; }             // pretty sure these wouldn't work anyway.
4.     public abstract GameObject RoundPrefab { get; set; }    // pretty sure these wouldn't work anyway.
5.     public abstract float MuzzleVelocity { get; set; }
6.     public abstract float ReloadTime { get; set; }
7.     [SerializeField]
8.     private float reloadTime;
9.  
10.     private float nextReload;
11.  
12.     public override void TriggerDown()
13.     {
14.     }
15.  
16.     public override void TriggerUp()
17.     {
18.     }
19. }

Problem is that the 2 floats (as well as the transform and gameObjects) give me the error

The thing is that I don't want to do anything with it here in the SubBaseClass - just declare it. Can I not do that?

 

P.S. I'm also not going to be doing anything in the TriggerDown() and TriggerUp() functions, as this is to be handled by the individual weapons and tool themselve - I'm emplementing an override here just to stop another error

Needless to say, inheritence is stll very new to me...

 

[sigh]

Wait... nevermind... in the name of being thorough I made this classe abstract true, and that sorted it.

I mistakenly thought I'd seen it written somewhere that an abstract class couldn't inherit from another abstract class...

Well don't I feel like a muppet, lol.
