A Snake game is a practical first project when you want to learn how to make a game on iPad. The rules are easy to explain: move the snake, collect food, grow, and end the run when the snake hits a wall or its own body.

In hyperPad, you can build that loop with Scenes, Objects, Attributes, UI, and visual Behaviors. Start with movement and one piece of food. Add growth only after those two parts work.

What you will build

Your first version needs:

one gameplay Scene
a snake head Object
one food Object
four touch controls
a score label in the UI
a game-over condition

A complete segmented body is a later step. A moving head that collects food is enough to test the core mechanic.

1. Set up the Scene

Create a new Project and add a gameplay Scene. Place the snake head near the center. Add four simple buttons to the UI layer for up, down, left, and right.

Choose a fixed movement distance, such as one grid cell. A visible grid can help you check that each move lands in the right place, but the grid does not need to appear in the finished game.

2. Store the movement direction

Add an Object Attribute named direction to the snake head. Give it an initial value such as right.

When the player touches a direction button, use Set Attribute to change that value. The Object Attributes guide explains how to create, set, and retrieve values stored on an Object.

Prevent an immediate reverse. If the snake is moving right, ignore a left input. This stops the head from turning directly into the body once you add segments.

3. Move one grid cell at a time

Use a repeating timer or loop to read the direction Attribute. Connect each possible value to a movement action:

up: increase the Y position
down: decrease the Y position
left: decrease the X position
right: increase the X position

Keep the interval slow while you test. Increase the speed later.

This Behavior chain introduces a useful programming pattern: an event triggers, a stored value is checked, and an action changes the game.

4. Add food and scoring

Place one food Object on an open grid position. Add a collision event between the snake head and the food.

When the collision happens:

add one point to the score
move the food to another open position
record that the snake should grow

Use a Box Container or Attribute for the score. Then send the updated value to a text label in the UI. You can review how Behavior outputs move between connected actions in Sharing Values Between Behaviors.

5. Build the snake body

A simple body system records the head's previous grid positions. Each body segment moves to the position that the segment ahead of it just left.

Build this in stages:

add one body segment
confirm it follows the head
add a second segment
confirm both keep the same spacing
create another segment only after food is collected

If the body bunches up or cuts corners, inspect the saved positions before changing the speed.

6. End the run

Add walls around the play area. A collision between the head and a wall should stop movement and show a game-over panel.

For self-collision, tag the body segments and check whether the head touches an Object with that tag. The Object Tags guide shows how tags can reference a group of Objects.

Your game-over panel can include the final score and a restart button that reloads the gameplay Scene.

7. Playtest the rules

Test one rule at a time:

each button changes direction once
opposite-direction input is ignored
food never stays under the snake
one food item adds one point
a new segment appears in the correct place
wall and body collisions end the run
restart clears the score and body

Short tests make the source of a bug easier to find.

Add your own mechanic

Once the basic loop works, change one rule. Add obstacles, timed food, a shrinking play area, portals, or a second type of collectible. One clear twist gives the project its own identity.

Share the working prototype on the hyperPad Hub and ask players whether the controls feel responsive and whether the speed increases fairly.

Build the first playable version

Build one short playable loop around the main movement or action. Test the controls, feedback, and restart flow before adding another level.
