Detailed Description

Check for collisions with other GameObject entities.

Constructor & Destructor Documentation

this()

ComponentCollision::this ( size_t owner, ComponentTransform transform, ComponentPlayerInputJump jump, bool * isActive )

inline

Set up the script.

Parameters

owner	the id of the linked GameObject.
transform	the ComponentTransform of the linked GameObject.
jump	the ComponentPlayerInputJump of the linked GameObject.
isActive	a pointer to whether the linked GameObject is active.

Member Function Documentation

CheckForFloorCollision()

void ComponentCollision::CheckForFloorCollision ( GameObject other, const SDL_Rect * camera )

inline

Check whether a floor collision will happen on the next frame update.

Check whether the current gravity, velocity, and position will result in a floor collision. If so, adjust the gravity/velocity value to land perfectly on top of the floor object.

HandleCollision()

void ComponentCollision::HandleCollision ( GameObject collidee, const SDL_Rect * camera )

inline

Check for collisions with other GameObject entities.

If a collision is found, mark the player as inactive since they are now "dead."

Note: this intentionally does not differentiate between floor and enemy collisions. It is expected that CheckForFloorCollision has already been run.

rotateRect()

SDL_Rect ComponentCollision::rotateRect ( SDL_Rect rect, float angle, SDL_Rect box )

inline

Rotate a hitbox rectangle based on the rotation angle of the GameObject.

Parameters

rect	the original position.
angle	the angle to rotate by (either 90, 180, 270, or 0).
box	the rotation point.

Update()

override void ComponentCollision::Update ( )

inlinevirtual

Update internal state of the script.

Implements ComponentScript.
