|scale||The scaling factor to be applied to gravity for all particles.|
With this function you can set the gravity scale factor for
particles in the physics simulation. The function is designed to
help prevent instability in the physics simulation, especially when
using very small particles which may behave unpredictably (i.e.
break conservation of momentum) in scenarios such as explosions.
Slowing these particles down by reducing gravity scale can
stabilize their behaviour. This function is global in scope,
in that it will change the gravity scale not just for new particles
created after the change, but also for those already present in the
NOTE: Adjusting the number of update iterations per step (using the function physics_world_update_iterations can also affect the effect of gravity on particles. Larger iteration sizes confer greater resistance to gravity.
The above code will set the base properties for all particles in the simulation.
