How to Use the Slow Mode Manager

Introduction

The SlowModeManager is a utility designed to manage slow mode configurations for an FTC robot, enabling dynamic speed adjustments using gamepad inputs. This allows for more precise control, particularly during delicate maneuvers.

Note: The slow mode factor is a DIVISION factor, meaning a factor of 2.0 will halve the speed.

Creating a SlowModeManager

There are multiple ways to initialize a SlowModeManager:

SlowModeManager slowModeManager = SlowModeManager(new SlowModeMulti(SlowMode.basic()));

Constructors

SlowModeManager(SlowModeMulti slowModeMulti)

Core Methods

double apply(double value) - Adjusts a given value based on the currently active slow mode.
DrivePowerCoefficients apply(DrivePowerCoefficients drivePowerCoefficients) - Modifies drive power coefficients.
void update(onFunc,offFunc) - Updates the active slow mode based on gamepad input. OnFunc being the function to call when the slow mode should be activated, and offFunc being the function to deactivate it.
void telemetry(Telemetry telemetry) - Displays the current slow mode in telemetry.

2. `SlowModeMulti`

The SlowModeMulti class defines an individual slow mode configuration, specifying activation and deactivation buttons.

Creating a SlowModeMulti

SlowModeMulti slowMode = new SlowModeMulti(SlowMode.basic());

The Constructors

SlowModeMulti(SlowMode slowModeData)

Built-in Configurations

static SlowModeMulti basic() - Returns a slow mode with a factor of 2.0.

3. `SlowMode`

The SlowMode class defines a slow mode with a configurable factor.

Creating a SlowMode

SlowMode slowMode = new SlowMode(2); // Reduces speed by half

Singular Constructor

SlowMode(double slowModeFactor)

Predefined Modes

static SlowMode basic() - A factor of 2.0.
static SlowMode one() - A factor of 1.0 (no change).
static SlowMode of(double slowModeFactor) - Creates a custom slow mode factor.

Usage Example

This example demonstrates how to integrate SlowModeManager with a gamepad.

SlowMode slowMode = new SlowModeMulti(SlowMode.basic()));
SlowModeManager slowModeManager = new SlowModeManager(slowMode);

// Applying slow mode to a value
double modifiedSpeed = slowModeManager.apply(1.0);

With this setup, your FTC robot can dynamically adjust its movement speed based on gamepad input, providing better control during gameplay.
