Explanation
- Headers:
<iostream>: For input and output operations.<iomanip>: For formatting the output precision.<thread>: For usingthis_thread::sleep_for()to simulate real-time movement.<chrono>: For time duration used insleep_for().
- Function Definitions:
void updatePosition(float& x, float& y, float throttle, float direction): Updates the position of the aircraft based on the throttle and direction.- Parameters:
x: The current x position of the aircraft.y: The current y position of the aircraft.throttle: The current speed of the aircraft.direction: The direction in radians.
- Uses trigonometric functions (
cosandsin) to calculate the new position based on the throttle and direction.
- Parameters:
- Main Function:
- Initialization:
- Initializes the aircraft’s position (
xandy), throttle, and direction.
- Initializes the aircraft’s position (
- User Commands:
'w': Increases the throttle.'s': Decreases the throttle, ensuring it doesn’t go below zero.'a': Turns the aircraft left by decreasing the direction angle.'d': Turns the aircraft right by increasing the direction angle.'q': Quits the simulation.
- Position Update:
- Calls
updatePosition()to update the aircraft’s position based on current throttle and direction.
- Calls
- Real-time Simulation:
this_thread::sleep_for(chrono::milliseconds(100));: Adds a delay to simulate real-time movement and control.
- Initialization:
Notes:
- Real-Time Simulation: The
sleep_for()function introduces a short delay to mimic the real-time nature of flight control. - Direction: The direction is in radians; you might want to convert to degrees for easier understanding in more complex simulations.
- Throttle and Direction Control: The program provides basic controls to change the throttle and direction, simulating movement on a 2D plane.
