simulation.loadStamp

Does something

simulation.neighbors

type sim.neighbors(number x, number y, [number rx], [number ry])

Used for iterating through particles in an area centred on the given coordinates (x, y). Radius in the x and y directions is set by rx and ry. Default radius is 2, 2.

The size of the rectangular area is one plus twice the radius, so a radius of 2, 2 gives a 5x5 pixel area centred on x, y. Particles in the centre position x, y are excluded. Only one particle in each position is included, and energy particles (such as photons, neutrons, electrons) are ignored.

Example:

for i,nx,ny in sim.neighbors(100,200,1,1) do
 sim.partProperty(i, sim.FIELD_TEMP, 9999)
end

Or if coordinates of the neighbouring particles are not required:

for i in sim.neighbors(100,200,1,1) do
 sim.partProperty(i, sim.FIELD_TEMP, 9999)
end

simulation.neighbours

Get the index of a particle at the specified position

simulation.partKill

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

simulation.partNeighbors

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.partNeighbours
