I tried to make a new element heal stkm but for some reason it only works when it is in the update function but thta causes loads of lag. I created the solution of writing "

lasttime = 0 

if os.time() > lasttime then 

lasttime = os.time()  

for i in sim.neighbors(x,y,8,8) do
if sim.partProperty(i, sim.FIELD_TYPE) == elements.DEFAULT_PT_STKM or sim.partProperty(i, sim.FIELD_TYPE) == elements.DEFAULT_PT_STK2 then
sim.partProperty(r, sim.FIELD_LIFE, 100)
end
end"

but when i added the lag reducing bit (the bit with os.time() and lasttime) it stopped working, and i don't know why or how to fix it

how do i fix it or what is an alternative method of achieving a stickman healing device
