Function Documentation

int collide_asteroid_ship ( obj_pair *  pair)

Checks asteroid-ship collisions.

Parameters
pairobj_pair pointer to the two objects. pair->a is asteroid and pair->b is ship.
Returns
1 if all future collisions between these can be ignored

Definition at line 183 of file collidedebrisship.cpp.

int collide_asteroid_weapon ( obj_pair *  pair)

Checks debris-weapon collisions.

Parameters
pairobj_pair pointer to the two objects. pair->a is debris and pair->b is weapon.
Returns
1 if all future collisions between these can be ignored

Definition at line 92 of file collidedebrisweapon.cpp.

int collide_debris_ship ( obj_pair *  pair)

Checks debris-ship collisions.

Parameters
pairobj_pair pointer to the two objects. pair->a is debris and pair->b is ship.
Returns
1 if all future collisions between these can be ignored

Definition at line 31 of file collidedebrisship.cpp.

int collide_debris_weapon ( obj_pair *  pair)

Checks debris-weapon collisions.

Parameters
pairobj_pair pointer to the two objects. pair->a is debris and pair->b is weapon.
Returns
1 if all future collisions between these can be ignored

Definition at line 40 of file collidedebrisweapon.cpp.

int collide_predict_large_ship ( object *  objp,
float  distance 
)

Definition at line 967 of file objcollide.cpp.

int collide_remove_weapons ( void  )

Definition at line 1039 of file objcollide.cpp.

int collide_ship_ship ( obj_pair *  pair)

Checks ship-ship collisions.

Returns
1 if all future collisions between these can be ignored because pair->a or pair->b aren't ships
Otherwise always returns 0, since two ships can always collide unless one (1) dies or (2) warps out.

Definition at line 1064 of file collideshipship.cpp.

void collide_ship_ship_sounds_init ( )

Definition at line 947 of file collideshipship.cpp.

int collide_ship_weapon ( obj_pair *  pair)

Checks ship-weapon collisions.

Parameters
pairobj_pair pointer to the two objects. pair->a is ship and pair->b is weapon.
Returns
1 if all future collisions between these can be ignored

Definition at line 469 of file collideshipweapon.cpp.
