Notes

• we need a collisionshape to tell the physics engine the boundaries of this plane
• add a child node CollisionShape2D to the CharacterBody2D root node of this scene
• in the Inspector, click on Shape to determine what type of shape we are using

create script for falling

• hit the 'attach new or existing script' button on the upper right corner of the scene dialog

• make sure that the script:

  • inherits from CharacterBody2D
  • the Template is 'Node Default'
  • Built in Script is OFF

script functions

• ready() starts when node is set
• process() is called every time a frame is called

• NOTE: better to use physics_process because that's what the engine is going to use

  • so change process to physics process

    _physics_process(delta: float) ->void:

CharacterBody2D

properties

velocity

• has an 'x' and a 'y'

up_direction

• tells physics engine how to know if we are on a floor or not
• can tell us if we are on a ceiling or a wall
