Homing Missile Demo – PlayBASIC
 
  This PlayBASIC demo showcases homing missiles that track and chase the mouse pointer. The missiles launch from random screen edges, dynamically adjusting their direction to home in on the target (mouse cursor). When a missile impacts the target, an explosion effect is triggered. 

Key Features:
 
  - Missile Homing Logic: Each missile initially launches with a predefined direction but continuously adjusts its angle to pursue the target. The missile's turning speed is controlled by a rotation algorithm that accounts for its current and desired direction.
  - Target Tracking: The mouse pointer serves as the target. A smoothing function (curvevalue) ensures missiles respond naturally rather than abruptly snapping to position. 
  - Explosion Effects: When a missile reaches the target, a particle-based explosion is generated. Explosions gradually fade out and remove themselves when fully dissipated. 
  - Frame Rate Control: The program caps execution at 60 FPS for smooth rendering. 
  - Missile Behavior: 
  - Just Launched: A brief delay before engaging the target. 
  - Homing: Actively adjusts its trajectory toward the mouse. 
  - Given Up: If unable to reach the target within a set timeframe, the missile stops tracking. 
  - Dead: Removed from play after impact or exiting the screen. 



  This demo primarily focuses on implementing and refining homing missile behavior, making it a great example of AI-driven projectile motion in 2D games.
