Description

Methods

Public constructor Create(const Config: TGameConfig; Seed: Cardinal);

Starts a ready match with deterministic generation. Raises EArgumentException on invalid configuration.

Parameters
Config
Valid dimensions/speed/lives; 1..CampaignLevelCount levels, nonnegative finite LevelSpeedIncrease, MaxBallSpeed at least BallSpeed.
Seed
Reused on restart to reproduce the board and launch sequence.

Source: src/Breakout.Game.pas (line 38).

Public procedure Execute(Command: TGameCommand);

Applies one lifecycle command. Launch starts Ready, or loads the next board in Ready after LevelComplete while preserving lives/score. Victory requires Restart, which resets the whole seeded match. DebugStep advances once only when paused; it can change state after a loss or final brick.

Source: src/Breakout.Game.pas (line 43).

Public procedure MovePaddle(CenterX: Double; AllowPaused: Boolean = False);

Moves the paddle in Ready/Playing and carries the ready ball. Paused diagnostics may opt in to reposition only the paddle between debug steps; the ball and simulation remain frozen.

Parameters
CenterX
Requested center in logical units, clamped to the field.
AllowPaused
Explicit permission from the diagnostics input adapter.

Source: src/Breakout.Game.pas (line 49).

Public procedure Step;

Advances one FixedDeltaSeconds quantum only while Playing. Earliest impacts consume time, reflect velocity and continue the remaining interval, up to MaxImpactsPerStep.

Source: src/Breakout.Game.pas (line 53).

Public function Snapshot: TGameSnapshot;

Returns values and a copy of the brick array. Painting this snapshot must not call Step or modify the live engine.

Source: src/Breakout.Game.pas (line 56).
