Checkpoint 3

**Checkpoint 3** is a Checkpoint following Alien Blaster, with five puzzles. It acts as explaining the basics of almost every game you may build.

## 1. Hey! UFO!

This puzzle is associated with the "Do You Believe in UFO Nodon?" segment of Alice's Guide.

### Nodon

Noninteractive Nodon
* Puzzle Clear
* Person
* Object
* Fancy Object
* World
* Game Screen

Interactable Nodon

### Solution(s)

Currently, the UFO Nodon has no controls. The two Stick Nodon are also awaiting connection. Thus, the logical solution is to connect the 'Left/Right' Stick Nodon to the UFO Nodon's '⬌Left/Right' port, and connect the 'Up/Down' Stick Nodon to the UFO Nodon's '⬍Up/Down' port. This gives controls to the UFO, allowing it to move to the apple towards the Person, who will then destroy it, clearing the puzzle.

## 2. Connect to Build Shapes

This puzzle is associated with the "Connecting Objects" segment of Alice's Guide.

### Nodon

Noninteractive Nodon
* Object Break
* Puzzle Clear
* Person
* Object
* Fancy Object
* World
* Game Screen

Interactable Nodon

### Solution(s)

First, to satisfy the connection port needs, connect the Object Nodon's lower connection port to the Moving-Object Nodon's upper connection port. However, we're not done here, because if we go over to the game screen, we can see that the Object is not connected to the Moving Object in the right way - the goal is to make the Moving Object push the apple to the Person and clear the puzzle. We can fix this by going into the Object Nodon's settings. Here, we can modify the Connection Points. Set 'Own Connection Point' to 'X-' and 'Target Connection Point' to 'X+'. This should orient the two objects in such a way that the apple can be reached and pushed into the Person, clearing the puzzle.

## 3. Making the Person Unbreakable

This puzzle is associated with the "Destructive/Destructible Settings" segment of Alice's Guide.

### Nodon

Noninteractive Nodon
* Stick
* Object Break
* Puzzle Clear
* Person
* Object
* Fancy Object
* World
* Game Screen

Interactable Nodon

### Solution(s)

As it is, pushing the sphere into the wall breaks it, but as a side effect, the sphere also breaks the Person. But we can't modify the Person's settings to make it indestructible. Instead, we need to change the Object Nodon's 'Destructive' detailed settings. Disable everything except for 'Cylinder'. This should make it so that it still destroys the wall, but not the Person.

## 4. Stopping with NOT

This puzzle is associated with the "The Contrarian NOT Nodon" segment of Alice's Guide.

### Nodon

Noninteractive Nodon
* Puzzle Clear
* Object
* Fancy Object
* Moving Object
* Teleport Object Entrance
* World
* Game Screen

Interactable Nodon

### Solution(s)

Currently, if we try to move towards the apple, we can reach the spot where it will end up, but the Moving Object at the top won't have reached it. Instead, we need a way to keep the Moving Object moving but keep the Person in place. As such, delete the direct connection between the Button Nodon and Person Nodon, and instead connect the Button Nodon to the input port of the NOT Nodon. Then, connect the output port of the NOT Nodon to the ⬌Left/Right input port of the Person Nodon. This'll make it so we can stop the Person before the apple disappears into "subspace", and still move the apple towards the lower platform.

## 5. The Meaning of AND

This puzzle is associated with the "AND Nodon, Reporting for Duty!" segment of Alice's Guide.

### Nodon

Noninteractive Nodon
* Puzzle Clear
* Person
* Object
* Fancy Object
* Moving Object
* World
* Game Screen

Interactable Nodon

### Solution(s)

Currently, nothing can be done to change anything about the level on the game screen. Attaching one Button Nodon to the AND Nodon connected to the Moving Object won't do anything, either. Because of the way the AND Nodon works, we need to connect both Button Nodon to the AND Nodon. Don't worry about which Button Nodon connects to which input port. Then, press both the left and right bumpers to move the box, which pushes the apple into the Person, clearing the puzzle.
