# [BaseBotGame] 2022-10-03 Pitcher
### Object
Pitcher pitch
- Input: Pitcher
- Output: pitch position and if it's a strike

### Behavior
Pitcher pitch a ball randomly locate at a zone. Then, the strike zone object determines whether it's a strike or not.

### Algorithm
Basic Class:
1. `Grid` object has `x`, `y` coordinate
2. `Pitch` object stands for a pitching result including position represented by `Grid`

Pitch:
1. `BaseballPlayer` has `name`, `number`, and `fieldPosition`
2. `Pitcher` inherits from `BaseballPlayer` and extend `pitch` method
3. `pitch` method return a random position

const int max_x = 5;
const int max_y = 5;
pitch.pos.x = rand() % max_x
pitch.pos.y = rand() % max_y

Strike Zone:

| | | | | |
|---|---|---|---|---|
| x | x | x | x | x |
| x | o | o | o | x |
| x | o | o | o | x |
| x | o | o | o | x |
| **x** | x | x | x | x |
1. The origin locates at the left bottom grid(bold x) and goes to right and top.
2. `StrikeZone` object has 2 `Grid`: `leftBot` and `rightTop` form a rectangular.
3. `isStrike` method takes a `Pitch` as input and if the position of pitch is in the rectangular it's a strike

bool isSstrke = leftBot.x <= pitch.pos.x <= rightTop.x && 
               leftBot.y <= pitch.pos.y <= rightTop.y;
