Intermediate C++ Game Programming Tutorial 17

In the video we take a look at a couple of bangers from <algorithm>, and we learn what lambda functions are and how to use them.

Topics Covered

• Mutable modifier for member data

Part 2 Class Specification

All of the meme entities of the system will have the following shared functionality:

• Member data for name (string), hp, speed, and power (int)
• Getters for name, initiative (speed + 2d6), and alive state
• Punch function that takes a different meme entity and applies damage (str + 2d6) to it
• Tick function where the entity recovers 1d6 hp

Functions should narrate actions / effects when it makes sense. Tests should be made to check whether a character is alive before an action is performed (dead characters can't punch, recover, etc.)

There are two concrete entites: MemeFrog and MemeStoner MemeFrog:

• Has 69 hp, 7 speed, and 14 power
• Has a SpecialMove function that takes an entity and has a 1/3 chance of dealing 3d6 + 20 damage
• Takes 1d6 of damage every turn

MemeStoner:

• Has 80 hp, 4 speed, and 10 power
• Has a SpecialMove function that takes no parameters and has a 1/2 chance of adding 3 speed, increasing power by 69/42, adding 10 hp, and adding to the entity's name

Homework
