ParticleSystem

ParticleSystem emits bounded screen-facing particles from Lua. Emission is global and does not require a Particle System component.

ParticleSystem.Emit(x, y, z, velocityX, velocityY, velocityZ, lifetime[, r, g, b]) emits one particle. RGB defaults to white. ParticleSystem.Clear() removes all active particles.

function Burst(gameObjectId)
  local position = Transform.GetPosition(gameObjectId)
  if position ~= nil then
    for index = 1, 6 do
      ParticleSystem.Emit(
        position.x, position.y, position.z,
        (index - 3) * 0.25, 1.5, 0.0,
        0.65,
        255, 196, 96
      )
    end
  end
end

Emission is capped by the runtime particle pool. Avoid unbounded per-frame loops and design effects to remain readable when the pool is busy.
