Detailed Description

Trap which shoots arrows on a timer in a specified direction

The arrows fly until they collide with something, at which point they disappear.

Originally I wanted arrows to "stick" into walls, but this would lead to a large amount of arrows stuck to the wall, causing the game state to be larger and larger.

We can probably re-implement this after optimizing the newtorking code to only send info about objects that have updated.

Constructor & Destructor Documentation

ArrowTrap()

ArrowTrap::ArrowTrap	(	glm::vec3	corner,
		Direction	dir
	)

Parameters

corner	Corner position of the spike trap
dir	What direction it should shoot in

Member Function Documentation

reset()

void ArrowTrap::reset ( ServerGameState &  state )

overridevirtual

Logic to reset the trap

At the highest level, this version just sets the triggered flag to false. Derivations of this should do additional resetting logic, and potentially call this Base class version as well to reset the common logic for all traps (currently just the triggered variable)

Parameters

state

GameState in case the trap needs to use the state for that

Reimplemented from Trap.

shouldReset()

bool ArrowTrap::shouldReset ( ServerGameState &  state )

overridevirtual

Resets the trap

Parameters

state

GameState, in case you need that to determine if the trap should reset

Returns

True if the trap should reset, false otherwise

Implements Trap.

shouldTrigger()

bool ArrowTrap::shouldTrigger ( ServerGameState &  state )

overridevirtual

Determines if the trap should be triggered

Parameters

state

GameState, in case you need that to determine if the trap should trigger

Returns

True if the trap should trigger, false otherwise

Implements Trap.

trigger()

void ArrowTrap::trigger ( ServerGameState &  state )

overridevirtual

Activates the trap

At the highest level, this just sets the triggered variable to true. Subclass versions of this will also probably want to call this function to set the triggered variable, in addition to any other common flags we add in later.

Parameters

state

State in case triggering the trap needs to affect the gamestate

Reimplemented from Trap.
