|
|
Answer the questions while completing the tutorial. Pay attention to the dialogues!
|
||
|
|
|
||
|
|
## 1. Write the code that randomly generates a number between 0 and 4 and stores that value in a global variable called 'mine x'.
|
||
|
|
|
||
|
|
<br />
|
||
|
|
|
||
|
|
```
|
||
|
|
mineX = Math.random(5)
|
||
|
|
```
|
||
|
|
|
||
|
|
## 2. Write the code to plot the point with coordinates of (select x, select y) as shown. Your code should apply the concept of `led->plot ( , )`
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
<br />
|
||
|
|
|
||
|
|
```
|
||
|
|
selectX = 0
|
||
|
|
selectY = 0
|
||
|
|
led.plot(selectX, selectY)
|
||
|
|
```
|
||
|
|
|
||
|
|
## 3. Write the code to plot the point with coordinates of (select x, select y) as shown. Your code should apply the concept of `led->plot ( , )`
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
<br />
|
||
|
|
|
||
|
|
```
|
||
|
|
selectX = 2
|
||
|
|
selectY = 2
|
||
|
|
led.plot(selectX, selectY)
|
||
|
|
```
|
||
|
|
|
||
|
|
## 4. How do you check if a dot is one away from given x and y coordinates?
|
||
|
|
|
||
|
|
<br />
|
||
|
|
|
||
|
|
<br />
|
||
|
|
|
||
|
|
```
|
||
|
|
if (mineX + 2 > selectX && selectX > mineX - 2 && mineY + 2 > selectY && selectY > mineY - 2) {
|
||
|
|
}
|
||
|
|
```
