Game Dev Journey

Game Assets:

All of the assets required can be downloaded here.

The sprites are in the Traps --> Platforms

Folder.

Add the Platforms folder to the FileSystem

Level Design:

Create any level you like.

You may copy my level layout.

We will spawn Strawberries dynamically

Also, we will create scenes for a Horizontal platform and Vertical Platform

You don't have those yet

How to make the chain / rail paths

The chain is just a TextureRect node

Which uses the Chain.png image as the texture

Set the Stretch mode to Tile

Now you can stretch the image

Rotate it 90 degrees for vertical rails

Select the RailLevel node

Attach a Script to it

Set the number of strawberries you plan

to use in the level

Top and Bottom Markers

In the RailLevel Scene

Add an Area2D

rename it to TopMarker

Add a CollisionShape2D

add a new RectangleShape2D

Repeat this for the BottomMarker

Add a new Node

Rename it to LiftStops

Place the Areas and their children in the group

Position these markers in the level

Vertical Rail Scene

Create a new scene with AnimatableBody2D as the root

This is so the player will move with the platform when on it

Rename it to HorizontalRail

Add a CollisionShape2D

Choose new RectangleShape 2D

Add an AnimatedSprite2D

Add a new Sprite Frames resource

Click on the SpriteFrames resource

Rename the default animation to "off"

Use the Brown Off.png as the only frame

Add a new animation

Rename it to "on"

Press Ctrl+Shift+O

Choose the Brown On.png file

Set Horizontal frames to 8

Set Vertical frames to 1

Select All

Add 8 frames

Set the off Autoplay

Turn on looping

Set FPS to 15

Add a RayCast2D node

Set Target Position Y to -20

In the Collide With section

Allow the ray to collide with Areas

Set the Collision Mask to look for objects

on Mask 6

Add an Area2D node as a child of VerticalRail

Add a CollisionShape2D node as a child of Area2D

Add a New RectangleShape2D

Extend the Area2D collision shape above the platform

The Vertical Rail will work as a lift

The player will press a button

to activate it.

Add a Label node as a child of VerticalRail

Set the text property of the label

to:

Press E

To move

Position the label above the platform

in the scene

Then hide the label

Attach a script to the VerticalRail node

Get a reference to the AnimatedSprite2D so that

we can play the off and on animations

Get a reference to the RayCast2D so we can stop at the top and the bottom

Get a reference to the label so that we can toggle visiblity

Create variables to

set the direction

set the speed

flag if the platform is moving

flag if the player is on the platform

The platform can only move

when the player is on it

and the player presses "E"

Connect the body entered signal

of the Area2D

Set up and interact action in the Input Map

Click on Project --> Project Settings --> Input Map

Add a New Action called interact

Map a key to it such as E

In the body entered function

Check if the body is the player

then set on_lift to true

make the label visible

Connect the body exited signal

of the Area2D so that we know

when the player has left the lift

Code the body exited function

check if the body is the player

set on_lift to false

hide the label again

In the process function

we should continuously check

if the player is on the lift

if the lift is not moving

and if the player has pressed the interact key

if they have then

set moving to true

Move the lift in the physics process function

if moving is true

play the "ON" animation

hide the label

continuously update the y position of the lift

if the ray cast collides with a marker

set moving to false

play the "OFF" animation

invert the target position

reverse the direction of the lift

NEXT: Vertical Fan
