** Export Annotation
|
|
|
|
|
|
|
|
|
|
annotation allows you to add property to the inspector on a node
|
|
|
|
|
|
|
|
|
|
*** format
|
|
|
|
|
#+BEGIN_SRC godot
|
|
|
|
|
@export var VARIABLE_NAME: TYPE = VALUE
|
|
|
|
|
#+END_SRC
|
|
|
|
|
|
|
|
|
|
this allows you to reference the property directly within the script attached to the node
|
|
|
|
|
|
|
|
|
|
** Setting up an Input System
|
|
|
|

|

*** detecting the input
|
|
|
|
|
- we use these:
|
|
|
|
|
- Input.is_action_just_pressed
|
|
|
|
|
- Input.is_action_just_released
|
|
|
|
|
- Input.is_action_pressed
|
|
|
|
|
|
|
|
|
|
- just_pressed detects only the initial press of the button. a lot of times you hit the button and the computer will detect it multiple times.
|
|
|
|
|
- so make sure you DO NOT use just_pressed, use action_pressed!
|
|
|
|
|
|
|
|
|
|
** get axis
|
|
|
|
|
instead of using if statements, you can use Input.get_axis
|
|
|
|
|
|
|
|
|
|
this takes two actions, and determines if they are both pressed at the same time, or if only 1 is pressed
|
|
|
|
|
|
|
|
|
|
Input.get_axis("left", "right") will return a value of -1, 0, 1
|
