_46ED8A_collide_against_sprite_objects()

void _46ED8A_collide_against_sprite_objects

(

Pid

pid

)

CollideIndoorWithDecorations()

void CollideIndoorWithDecorations

(

)

Original binary offset:

0x0046E0B2.

CollideIndoorWithGeometry()

void CollideIndoorWithGeometry

(

bool

ignore_ethereal

)

Original binary offset:

0x0046E44E.

Performs collisions with level geometry in indoor levels. Updates collision_state.

Parameters

ignore_ethereal

Whether ethereal faces should be ignored by this function.

CollideIndoorWithPortals()

bool CollideIndoorWithPortals

(

)

Original binary offset:

0x0046F04E.

Performs collision checks with portals. Updates collision_state. If the collision did happen, then adjusted_move_distance member is set to 0xFFFFFF (basically a large number).

Returns

True if there were no collisions with portals.

CollideOutdoorWithDecorations()

void CollideOutdoorWithDecorations

(

Vec2i

gridPos

)

Original binary offset:

0x0046E26D.

Parameters

gridPos

Grid coordinates.

CollideOutdoorWithModels()

void CollideOutdoorWithModels

(

bool

ignore_ethereal

)

Original binary offset:

0x0046E889.

Performs collisions with models in outdoor levels. Updates collision_state.

Parameters

ignore_ethereal

Whether ethereal faces should be ignored by this function.

CollideWithActor()

bool CollideWithActor	(	int	actor_idx,
		int	override_radius
	)

Original binary offset:

0x0046DF1A.

Parameters

actor_idx	Actor index.
override_radius	Override actor's radius. Pass zero to use original radius.

Returns

Whether the collision is possible.

CollideWithParty()

void CollideWithParty

(

bool

jagged_top

)

Original binary offset:

0x0046EF01.

Parameters

jagged_top

Makes collision happen even if the monster would end up above the party. However, for the collision to happen, corresponding bounding boxes still need to intersect.

hasShorterSolution()

bool hasShorterSolution	(	const float	a,
		const float	b,
		const float	c,
		const float	curSoln,
		float *	outNewSoln,
		bool	inside = false
	)

Finds whether this quadratic (of the form AX^2 + BX + C = 0) can be solved and if the solution is smaller than out current solution. Returns true if a smaller non negative solution is found.

Parameters

	a	A component of quadratic.
	b	B component of quadratic.
	c	C component of quadratic.
	curSoln	Current input smallest solution to test against.
[out]	outNewSoln	New smallest non negative solution. This value is not set if the function returns false.
	inside	If you want collision with any point inside radius - for cylinder decorations/party

Returns

True if the quadratic has a valid solution that is smaller than the input curSoln.

ProcessActorCollisionsBLV()

void ProcessActorCollisionsBLV	(	Actor &	actor,
		bool	isAboveGround,
		bool	isFlying
	)

Handles actor movement - performs collision detection, updates actor's position, handles sliding on slopes, deceleration, etc.

Parameters

actor	Actor to move.
isAboveGround	Whether the actor is currently above ground (stands on air, basically).
isFlying	Whether the actor is a flying creature that can fly (e.g. not paralyzed).

ProcessActorCollisionsODM()

void ProcessActorCollisionsODM	(	Actor &	actor,
		bool	isFlying
	)

ProcessPartyCollisionsBLV()

void ProcessPartyCollisionsBLV	(	int	sectorId,
		int	min_party_move_delta_sqr,
		int *	faceId,
		int *	faceEvent
	)

ProcessPartyCollisionsODM()

void ProcessPartyCollisionsODM	(	Vec3f *	partyNewPos,
		Vec3f *	partyInputSpeed,
		int *	floorFaceId,
		bool *	partyNotOnModel,
		bool *	partyHasHitModel,
		int *	triggerID
	)
