Physics Simulation Engine
Crane Rush implements a custom physics calculation system optimized for mobile touch-screen latency constraints. The crane hook executes pendulum motion governed by gravitational acceleration constants, while suspended building segments inherit velocity vectors from the parent attachment point.
Collision detection operates on a per-frame basis, evaluating vertex intersection between descending blocks and the existing tower structure. Stability algorithms assess the contact surface area ratio between consecutive floors, triggering collapse animations when weight distribution exceeds structural thresholds.
Visual effects rendering separates foreground gameplay elements from background atmospheric particles. White glow halos utilize additive blending for luminous outline definition against the navy blue environmental backdrop, ensuring consistent visibility across diverse screen brightness configurations.
