Hello! This is my new material, MGUN. It explodes when sparked, when over or 200.0 degrees, and under 5.0 pressure, releasing a lot of pressure and making PLSM.

It also have an explosion function, you can use if you want.

local NBOMB = elements.allocate("LUEZMA", "BOMB")

local function explosion(x, y, s)
    for px = -1, 1 do
        for py = -1, 1 do
            tpt.create(x + px, y - py, "PLSM")
            local pressure = sim.pressure((x + px) / 4.0, (y + py) / 4.0)
            sim.pressure((x + px) / 4.0, (y + py) / 4.0, pressure + s * 10)
            sim.velocityX((x + px) / 4.0, y / 4.0, px * s)
            sim.velocityY((x + px) / 4.0, (y - py) / 4.0, -py * s)

        end
    end
end

local function NBMB_update(i, x, y, s, n)
    local r = 1
    if sim.pressure(x / 4.0, y / 4.0) >= 5.0 then

        explosion(x, y, 1)
        tpt.delete(i)
    elseif tpt.get_property("temp", i) >= 473.15 then
        explosion(x, y, 1)
        tpt.delete(i)
    end

end

tpt.element_func(NBMB_update, elements.LUEZMA_PT_BOMB)

EDIT-1: Deleted explode when sparked code to reduce low FPS(still exploding when sparked)

 I don't know how to reduce FPS load, I agree with you

 I fixed it and now runs pretty faster, thanks for the idea
