The Simulation API allows for modifying the state and properties of particles, air and gravity

Methods

simulation.partNeighbours

number ... sim.partNeighbours(number x, number y, number radius, [number type])

Returns a list of particles indexes that neighbour the given coordinates that matches the given type (if it is specified) The resulting list does not contain the "origin particle"

simulation.partChangeType

nil sim.partChangeType(number index, number type)

Reliably change the type of a particle, this method avoids the side effects created by changing the type directly with the "partProperty" method.

simulation.partKill

nil sim.partKill(number index)
nil sim.partKill(number x, number y)

Reliably delete a particle at a specified index or location, this method avoids the side effects created by changing the type to 0/DEFAULT_PT_NONE with the "partProperty" method

simulation.partProperty

nil sim.partProperty(number index, object field, object value)

Set the property value on a particle specified by index

object sim.partProperty(number index, object field)

Get the property value on a particle specified by the index

The "field" may be a field name or field ID, see [bottom of page] for more information

simulation.partID

number sim.partID(number x, number y)

Get the index of a particle at the specified position

simulation.partPosition

number x, number y sim.partPosition(number index)

Get the location of the particle at the specified index

simulation.partCreate
