Doesnt detect particles very well it always detects oxygen but not fire

All the other elements on my modpack work fine with the detecting function however this one doesnt

The Lua API already has functions to detect neighboring particles and either return them in a table with simulation.partNeighbors() or as an iterator with simulation.neighbors().

So either you could change the first line of your Update() function to:

local tab = sim.partNeighbors(x, y, 1, 1)

Or you could delete the first line completely and change the for loop to:

for b in sim.neighbors(x, y, 1, 1) do
