keyboard

Key presses can be detected using two methods:

key_pressed

int key_pressed(int key)

Checks if a specific key has been pressed. This will return 0 after the first positive test, so you will get 1 only once.

Parameters

• key -

  Key to test

  void update_super_cool_level(void* data, float elapsed_ms)
  {
      if (key_pressed(KB_SPACE)) {
          // do something once per key click
      }
   }
  

Return

1 if the key was pressed or 0 otherwise

key_down

int key_down(int key)

Check if a specific key is being held down. This will return 1 as long as the key is being held down.

Parameters

• key -

  Key to test

  void update_super_cool_level(void* data, float elapsed_ms)
  {
      if (key_down(KB_RIGHT)) {
          // do something
      }
   }
  

Return

1 if the key is being held down or 0 otherwise
