* Notes
|
||
|
|
** Physics2D Nodes
|
||
|
|
- StaticBody2D :: useful for floor and walls
|
||
|
|
- CharacterBody2D :: characters
|
||
|
|
- set velocity
|
||
|
|
- physics collisions
|
||
|
|
- scripting
|
||
|
|
- AnimatableBody2D :: moving platforms and doors
|
||
|
|
- RigidBody2D :: objects that have gravity and can be pushed by other objects
|
||
|
|
- set force or impulse to it
|
||
|
|
- e.g. thrust for rocket, tennis ball hit by racket
|
||
|
|
|
||
|
|
** how it works
|
||
|
|
- we do not control position, the engine does
|
||
|
|
- we supply velocity or force
|
||
|
|
- engine calucates where we go and speed / position
|
||
|
|
|
||
|
|
** Area2D vs Physics2D
|
||
|
|
*** similarities
|
||
|
|
- has one or more CollisionShape2D
|
||
|
|
- Sprite2D
|
||
|
|
|
||
|
|
*** differences
|
||
|
|
- much easier on calculations
|
||
|
|
- checks if one shape overlapping another
|
||
|
|
- Area2D is much more inaccurate in collisions
