ForceMove (2 | 3)

Function. Simulates physics by applying forces, winds, and air resistance to a particle's position and velocity.

Each frame, the block calculates new position and velocity based on the applied forces and time delta. This is the primary block for physics-based particle motion.

Typically, you connect a particle's Position and Velocity properties as inputs, and route the outputs back to their respective updaters.

Properties & inputs:

• Position (input): Current position to update.
• Velocity (input): Current velocity to update.
• Air resistance (input | property): Drag coefficient. Good values are in range [0; 5]. Zero means no drag.
• Num. forces (property): Number of force vectors to apply.
• Force # (input | property): A force vector. The length and direction define the acceleration applied each second (e.g., gravity: {0, -980, 0}).
• Num. winds (property): Number of wind vectors.
• Wind # (input | property): A wind vector. Wind only has effect when Air resistance is non-zero. It applies a force proportional to the difference between wind speed and particle speed.

Outputs:

• Position: Updated position after applying physics.
• Velocity: Updated velocity after applying physics.
