Function Documentation

int bay_emerge_or_depart	(	object *	heavy_objp,
		object *	light_objp
	)

If light_obj emerging from or departing to dock bay in heavy_obj, no collision detection.

Definition at line 91 of file collideshipship.cpp.

void calculate_ship_ship_collision_physics

(

collision_info_struct *

ship_ship_hit_info

)

Definition at line 535 of file collideshipship.cpp.

int check_special_cruiser_asteroid_collision	(	object *	heavy,
		object *	lighter,
		float *	cruiser_mass,
		int *	cruiser_light
	)

Gets modified mass of cruiser in cruiser/asteroid collision so cruisers don't get bumped so hard. modified mass is 10x, 4x, or 2x larger than asteroid mass

Returns

1 if modified mass is larger than given mass, 0 otherwise

Definition at line 460 of file collideshipship.cpp.

bool check_subsystem_landing_allowed	(	ship_info *	heavy_sip,
		collision_info_struct *	ship_ship_hit_info
	)

Find the subobject corresponding to the submodel hit

Definition at line 507 of file collideshipship.cpp.

void collect_ship_ship_physics_info	(	object *	heavier_obj,
		object *	lighter_obj,
		mc_info *	mc_info_obj,
		collision_info_struct *	ship_ship_hit_info
	)

Definition at line 1315 of file collideshipship.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_do_sound	(	vec3d *	world_hit_pos,
		object *	A,
		object *	B,
		int	player_involved
	)

Determine what sound to play when two ships collide

Definition at line 958 of file collideshipship.cpp.

void collide_ship_ship_sounds_init

(

)

Definition at line 947 of file collideshipship.cpp.

void do_kamikaze_crash	(	object *	obj1,
		object *	obj2
	)

obj1 and obj2 collided. If different teams, kamikaze bit set and other ship is large, auto-explode!

Definition at line 998 of file collideshipship.cpp.

void get_I_inv	(	matrix *	I_inv,
		matrix *	I_inv_body,
		matrix *	orient
	)

Definition at line 853 of file collideshipship.cpp.

int get_ship_quadrant_from_global	(	vec3d *	global_pos,
		object *	objp
	)

Given a global point and an object, get the quadrant number the point belongs to.

Definition at line 935 of file collideshipship.cpp.

void hud_start_text_flash	(	char *	txt,
		int	t,
		int	interval
	)

int is_planet

(

object *

objp

)

Return true if *objp is a planet, else return false. Hack: Just checking first six letters of name.

Definition at line 900 of file collideshipship.cpp.

int maybe_collide_planet	(	object *	obj1,
		object *	obj2
	)

If exactly one of these is a planet and the other is a player ship, do something special.

Returns

true if this was a ship:planet (or planet_ship) collision and we processed it. Else return false.

Definition at line 910 of file collideshipship.cpp.

void maybe_push_little_ship_from_fast_big_ship	(	object *	big_obj,
		object *	small_obj,
		float	impulse,
		vec3d *	normal
	)

Response when hit by fast moving cap ship

Definition at line 1027 of file collideshipship.cpp.

void mcp_1	(	object *	player_objp,
		object *	planet_objp
	)

Procss player_ship:planet damage. If within range of planet, apply damage to ship.

Definition at line 875 of file collideshipship.cpp.

int ship_hit_shield	(	object *	obj,
		mc_info *	mc,
		collision_info_struct *	sshs
	)

int ship_ship_check_collision	(	collision_info_struct *	ship_ship_hit_info,

	)

Definition at line 111 of file collideshipship.cpp.

int ships_are_docking	(	object *	objp1,
		object *	objp2
	)

Return true if two ships are docking.
