# offset image challenges
Coding challenges for the offset image tutorial.
## Before we get started
Complete the following exercise. Your code should look like this:
```blocks
offset = 0
basic.forever(() => {
if (offset == -4) {
basic.showString("Push button A", 150)
}
images.createImage(`
. . # . .
. . # . .
. . # . .
. # # # .
. . # . .
`).showImage(offset)
})
input.onButtonPressed(Button.A, () => {
offset = offset + 1
})
```
### Challenge 1
Create a condition for if button `B` is pressed. We want the image to move to the left when button `B` is pressed.
```
offset = 0
basic.forever(() => {
if (offset == -4) {
basic.showString("Push button A", 150)
}
images.createImage(`
. . # . .
. . # . .
. . # . .
. # # # .
. . # . .
`).showImage(offset)
})
input.onButtonPressed(Button.A, () => {
offset = offset + 1
})
input.onButtonPressed(Button.B, () => {
offset = offset - 1 // ***
}) // ***
```
* Run the code to see if it works as expected.
### Challenge 2
Now we want to make sure that the button does not go off the screen to the right. Add a new line that checks to see if offset = 5 after button `A` is pressed.
If `offset = 5` then prompt the user to move the image to the left by displaying the text: "Push button B".
```
offset = 0
basic.forever(() => {
if (offset == -4) {
basic.showString("Push button A", 150)
}
if (offset == 5) {
basic.showString("Press Button B", 150) // ***
}
images.createImage(`
. . # . .
. . # . .
. . # . .
. # # # .
. . # . .
`).showImage(offset)
})
input.onButtonPressed(Button.A, () => {
offset = offset + 1
})
input.onButtonPressed(Button.B, () => {
offset = offset - 1
})
```
* Run the code to see if it works as expected.
### Challenge 3
Now make sure the image does not go off the left side and if it does, prompt the user to push button `A`.

# offset image quiz answers
shift an image horizontally across the display with offset.
This is the answer key for the [offset image quiz](/lessons/offset-image/quiz).
## 1. What is a 'if, then, else statement' ?
<br/>
An if-then statement will run a block of code if the condition specified is true. The statement will run the "else" block of code if that condition is false.
## 2. Consider the message
Write the line of code that that will create the message "Push button A" (Hint: This message appears `if` the offset is equal -4 then the BBC micro:bit will state "Push Button A").
<br/>
```
if (offset == -4) {
basic.showString("Push Button A", 150)
}
```
## 3. Consider the following image
![](/static/mb/lessons/offset-image-0.png)
When with this image be displayed?
<br/>
When the offset is NOT equal to -4 then the BBC micro:bit will show the image above.
## 4. Consider the following image
![](/static/mb/lessons/offset-image-1.png)
Write the two lines of code that cause the `variable` offset to increase by one when button `A` is pressed.
<br/>
```
input.onButtonPressed(Button.A, () => {
offset = offset + 1
})
```

## 6.
First, notice that moving the 1st micro:bit in the simulator in any direction, you will change the acceleration value of the 2nd micro:bit. Also, notice that by moving the micro:bit simulator, there is a changing acceleration value of the second micro:bit. Second, the flat colored horizontal line will start a waving line on the 2nd micro:bit to display the value of the strength as measured in milli-gravities. Finally, notice that the LED display will fluctate based on the movement of the 2nd micro:bit simulator.
