Macro Definition Documentation

ASSIGN_ARRAY_ITEM

#define ASSIGN_ARRAY_ITEM	(		array,
			index,
			type,
			item
	)		type *item = &array[index]

Assign the index th item in the array to an item variable of type

COUNT_IS_ALIVE

#define COUNT_IS_ALIVE	(		array,
			counter
	)

Value:

  uint8_t counter = 0;                                               \
  do {                                                               \
    for (uint8_t i = 0; i < sizeof(array) / sizeof(array[0]); i++) { \
      if (array[i].isAlive) {                                        \
        counter++;                                                   \
      }                                                              \

  } while (0)

Count the number of items in the array for which the isAlive member is true and assigns it to a variable defined as the int variable counter

FOR_EACH

#define FOR_EACH	(		array,
			index
	)		for (uint8_t index = 0; index < sizeof(array) / sizeof(array[0]); index++)

Iterate over an array with variable index

INIT_UNALIVED_ARRAY

#define INIT_UNALIVED_ARRAY

(

array

)

Value:

  do {                                                               \
    for (uint8_t i = 0; i < sizeof(array) / sizeof(array[0]); i++) { \
      array[i].isAlive = false;                                      \
    }                                                                \
  } while (0)

Set the isAlive member to false for all items in the array

RNDPM

#define RNDPM

(

)

(rndi(0, 2) * 2 - 1)

Return 1 or -1 randomly.

SKIP_IS_NOT_ALIVE

#define SKIP_IS_NOT_ALIVE

(

item

)

if (!item->isAlive) continue

Skip (continue) if the member isAlive of variable item is false.

TIMES

#define TIMES	(		count,
			index
	)		for (uint8_t index = 0; index < count; index++)

Iterate count times with variable index
