Disc class.
A disc, which can be fired at the grid. Has an associated PhysicsBody by default.
| Disc::Disc | ( | CIwFVec2 | position, | |
| DiscType | discColour | |||
| ) |
Disc constructor.
Creates a new disc of colour discColour at the specified position.
| [in] | position | Position the disc will be created at. |
| [in] | discColour | Colour of the disc (yellow or red). |
| Disc::~Disc | ( | ) |
Destructor - delete the disc.
Deletes the disc and its PhysicsObject, and releases any memory they were using.
| void Disc::Draw | ( | double | deltaTime | ) |
Draw the disc.
Draws the disc at the current position of its PhysicsObject.
| [in] | deltaTime | Time since the last update. |
| void Disc::DrawTrajectory | ( | float | currentStep, | |
| float | totalSteps | |||
| ) |
Draw the projected path of the disc.
Draws dots representing the path the disc will take when it is launched.
| [in] | currentStep | Current time step for the position calculation. |
| [in] | totalSteps | Total number of time steps to use for the position calculation. |
| int Disc::GetColour | ( | ) |
Get colour of the disc.
Returns the colour of the disc (yellow or red).
| CIwFVec2 Disc::GetDrawPosition | ( | ) |
Get draw position.
Returns the position the disc is being drawn at (top left corner) rather than its centre.
| std::pair< int, int > Disc::GetGridTarget | ( | ) |
Get the grid target of a disc.
Returns the target position of this disc in the grid. Used to check if the disc has reached its final destination.
| bool Disc::GetIsStuck | ( | ) |
Get whether this disc is stuck.
Get whether this disc has become stuck at the top of a full grid column. Stuck discs will be removed at the next update.
| PhysicsObject * Disc::GetPhysicsObject | ( | ) |
Get the disc's PhysicsObject.
Returns this disc's PhysicsObject. A discs PhysicsObject is only initialised when the disc is activated (when it is fired from the catapult).

Handle user input.
Moves the disc as the user drags it.
| bool Disc::HasClearedGrid | ( | ) |

Convert disc position to characters.
Convert the discs current position to a char array to be sent as a packet for multiplayer.
| void Disc::SetDrawPosition | ( | CIwFVec2 | position | ) |
Set draw position.

Set offset.
Offsets te discs draw position (top left corner) from it's actual position (centre).
| void Disc::SetPhysicsObjectPosition | ( | CIwFVec2 | position | ) |
Set physicsObject position.
Sets the position of the disc's associated PhysicsObject. Should only be called after the disc is launched/fired.
| [in] | position | New position. |
| void Disc::SetTarget | ( | float | y, | |
| int | column, | |||
| int | row | |||
| ) |
Set the grid target of a disc.
The target position of this disc in the grid. Used to check if the disc has reached its final destination.
| [in] | y | Y Position of the target grid tile. |
| [in] | column | Target column of the grid. |
| [in] | row | Target row of the grid. |
| CIwFVec2 Disc::StringToPosition | ( | std::string | str | ) |
Convert a string to a position.
Convert a received string (in multiplayer) to a disc position.
| [in] | str | The string to be converted. |
| void Disc::Update | ( | double | deltaTime | ) |
Update the disc.
Updates the position of the disc and its PhysicsObject depending on user touch inputs. Also handles multiplayer updates.
| [in] | deltaTime | Time since the last update. |
| void Disc::UpdateGridLogic | ( | ) |
Update logic.
Update the disc's grid logic (assign's a target, checks if it has landed, etc.)
