Let's assess your OOPs skills! 📋- This assessment gives us an idea of your fundamental OOPS concepts and Solid principles skills - Companies that evaluate this skillset in interviews: Hitwicket, GSN Games, Tomo Club, etc. - 10 Multiple Choice questions - Average time to complete: 7 to 10 minutes

Abstraction

Inheritance

Polymorphism

Encapsulation

A designer comes to you and asks you to make a level design tool for them so that they don’t have to worry about the code. This scenario is a perfect example of which OOPS concept?

Create another UI class and copy the code

Use the UI layer class and extend it for the animator UI

Create a new visual tool from scratch

Modify the existing UI class to accommodate functionality for both

Setup 20 different Gun classes

Create a Gun class and use the same class for the 20 different guns

Create specialized Gun Classes for shotguns, rifles, pistols, etc and use them to create 20 different guns

You are building a weapon system for a shooter game with 20 different guns. Which among the following is a good implementation?

Create a new melee class separately

A new melee class inheriting from the existing Gun class

Gun and melee classes inheriting from a newly created Weapon class

The design team now wants to add melee weapons into the game, what modifications would you make to your system?

There are 10 NPC objects of a single NPC class you created, including all the functions to interact with them, what OOP concept are you using?

A public variable for the parameters you need to set up

Using constructors for setting up the parameters

Creating a helper function for parameter setup

You need to set up these 20 NPCs at the beginning of the game, including their animations, and behaviour based on the type of NPC etc, during instantiation, you can do this using __________

Composition

You implement two functions for spawning these NPCs called SpawnNPC(Vec3 position) and SpawnNPC(Vec3 position, NPC type), this is a good example of __?

Setting up two different Dodge functions taking different arguments in the same NPC class

Setting up different Dodge implementations for different NPC classes separate from the Dodge implementation of the NPC base class

Adding more functionalities to specific NPCs

For an NPC behaviour system, which among the following could be used as an example for runtime polymorphism?

Create a base class called Destructible and all different entities can inherit from this class

Create an interface called Destructible and all different enemies can implement this interface

Separate Destructible classes for each entity

You are setting up destructible entities in the game, which can be powerup containers, enemies, environment props, etc. More such entities might be added later which can be destructible. How would you implement such a system?

Copy paste the code for each action for every enemy class

Use abstract classes for each action and enemies can inherit the action classes

Use interfaces for each action and enemies can implement the actions

You now want to set up 100 different actions out of which enemies can do a different number of actions. How would you go about doing it?
