Air resistance coefficient, F = kv

How often (in frames) world area checks are made

Physical entity to ignore during collisions

The 'objtype' passed to RayWorldIntersection

Prevents playing of material FX from now on

Stores this gravity and uses it if the current area's gravity is equal to the global gravity

Direction of movement

Initial orientation (zero means x along direction of movement, z up)

Acceleration that lifts particle with the current speed

Velocity threshold for bouncing to sliding switch

Speed threshold before this entity goes to sleep

Aligns this direction with the surface normal when sliding

The Physicalization flags for this particle.

Piercability for ray tests. Piercable hits slow the particle down, but don't stop it

Aligns this direction with the roll axis when rolling (0,0,0 to disable alignment)

Pseudo-radius

Thickness when lying on a surface (if left unused, size will be used)

Acceleration along direction of movement

Velocity along "heading"

Gravity when underwater

Water resistance coefficient, F = kv
