Detailed Description

initialization and handling of collisions and raycast basically everything that is released to or uses the ReactPhysics3D library

Constructor & Destructor Documentation

CollisionManager()

skr::fps2::Collision::CollisionManager::CollisionManager

(

)

constructor calls Init()

Member Function Documentation

AddCollisionToRooms()

void skr::fps2::Collision::CollisionManager::AddCollisionToRooms ( )

private

Adds collision to all walls and targets in all rooms.

AddCollisionToTarget()

void skr::fps2::Collision::CollisionManager::AddCollisionToTarget ( Renderer::OpenGL::TargetGeometry &  t )

private

adds collision boxes to all targest in a specified room

AddCollisionToTargets()

void skr::fps2::Collision::CollisionManager::AddCollisionToTargets ( )

private

adds collision to all targets in all rooms

AddCollissionWallToRoom()

void skr::fps2::Collision::CollisionManager::AddCollissionWallToRoom ( Renderer::OpenGL::RoomGeometry &  rg )

private

adds collision walls to specified room

Parameters

rg	RoomGeomtry of room specified

CheckCollision()

void skr::fps2::Collision::CollisionManager::CheckCollision

(

glm::vec3

currentPosition

)

checks collision between objects and uses callback for notification

Parameters

currentPosition

current Position of the player

CheckOverlap()

void skr::fps2::Collision::CollisionManager::CheckOverlap

(

glm::vec3

currentPosition

)

checks for overlaps between collision bodies as collision checks are quite expensive, for regular collision detection, overlap checks are enough

Parameters

currentPosition

current Position of the player

Cleanup()

void skr::fps2::Collision::CollisionManager::Cleanup

(

)

destroy everything related to ReactPhysics3D (RP3D), as doing it in the destructor is too late. As part of a global object, it gets called to late

ClearHits()

void skr::fps2::Collision::CollisionManager::ClearHits

(

)

clears list of registered hits

CollisionWorld()

rp3d::CollisionWorld * skr::fps2::Collision::CollisionManager::CollisionWorld

(

)

Gets pointer to the current collision world.

Returns

pointer to collision world

DrawHits()

bool skr::fps2::Collision::CollisionManager::DrawHits

(

)

get value whethere hits are visualized or not

Returns

true if hits are visualized, otherwise false

GetCurrentMeanNormalOfContactPoints()

glm::vec3 skr::fps2::Collision::CollisionManager::GetCurrentMeanNormalOfContactPoints

(

)

calculates mean normal of all contact points depending on the size of the collision shapes, RP3D return multiple contact points and in case of multiple shapes, with different normals. In an attempt to stop the player from glitching through corners, a mean normal is calcualted and used for sliding along walls

Returns

mean normal of all contact points

GetRaycastCallback()

RaycastCallback skr::fps2::Collision::CollisionManager::GetRaycastCallback

(

)

Gets the current raycast callback object.

Returns

raycast callback object

HitModelId()

size_t skr::fps2::Collision::CollisionManager::HitModelId

(

)

Gets the model id of the model used for hit visualization.

Returns

model id of the model used for hit visualization

Init()

void skr::fps2::Collision::CollisionManager::Init

(

)

initialization creates collision world, creates player collision box, adds collision to rooms and targets and initializes hit visualization

RayCast() [1/2]

void skr::fps2::Collision::CollisionManager::RayCast	(	glm::vec3	start,
		glm::vec3	dir
	)

triggers raycast default length is used

Parameters

start	current point of the player, where the raycasts starte
dir	of the raycast

RayCast() [2/2]

void skr::fps2::Collision::CollisionManager::RayCast	(	rp3d::Vector3	start,
		rp3d::Vector3	dir
	)

triggers raycast default length is used

Parameters

start	current point of the player, where the raycasts starte
dir	of the raycast

ResetContactPoints()

void skr::fps2::Collision::CollisionManager::ResetContactPoints

(

)

clears the list of contact points
