PlatformerController2D

A 2D platformer class for godot.

Changelog

Version 2.0

• Updated to Godot 4.0

  • Removed set and get functions in favour of properties

• Can now have negative jump height, which will reverse gravity

• Gravity is now positive when pointing down, and negative when pointing up

• Added 'jumped' and 'hit_ground' signals

• Split the large _physics_process function into multiple functions

Version 1.0.1

• Updated to Godot 3.4
• Fixed division by zero error when changing min jump height
• Other minor fixes

Installation

1. Add platformer_controller.gd to your project
2. Type extends PlatformerController2D to the top of your script
3. Add these input mappings in your project settings (or you can change the input variables in the inspector)
   • "move_left"
   • "move_right"
   • "jump"

Features

• Double jump
• Coyote time
• Jump buffer
• Hold jump to go higher
• Defining jump height and duration (as opposed to setting gravity and jump velocity)
• Assymetrical jumps (falling faster than rising)

Customization / Export variables

Here are the values that you can change in the inspector:

max_jump_height

The max jump height in pixels. You reach this when you hold down jump.

Min Jump Height

The minimum jump height (tapping jump).

Double Jump Height

The height of your jump in the air (i.e. double jump, triple jump etc.).

Jump Duration

How long it takes to get to the peak of the jump (in seconds).

Falling Gravity Multiplier

Multiplies the gravity by this while falling.

Max Jump Amount

How many times you can jump before hitting the ground. Set this to 2 for a double jump.

Max Acceleration

How much you accelerate when you hold left or right (in pixels/sec^2).

Friction

The higher this number, the more friction is on your character.

Can Hold Jump

If this is off, you have to press jump down every time you land. If its on you can keep it held.

Coyote Time

You can still jump this many seconds after falling off a ledge.

Jump Buffer

Pressing jump this many seconds before hitting the ground will still make you jump.
Note: This is only needed when can_hold_jump is off.

Input Variables
