The Powder Toy

Im making alpha particles but the tmp isnt detected so it doesnt start moving like electrons. Here's the script:

local alph = elements.allocate("Alph", "alph")
elements.element(alph, elements.element(elements.DEFAULT_PT_ELEC))
elements.property(alph, "Name", "ALPH")
elements.property(alph, "Colour", 0xFFDD00)
elements.property(alph, "Description", "Alpha particle.")
elements.property(alph, "Weight", -1)
elements.property(alph, "HeatConduct", 251)
elements.property(alph, "Temperature", 295.15)
elements.property(alph, "Properties" , 0x10410)
elements.property(alph, "AirLoss", 1)
elements.property(alph, "Loss", 1)
elements.property(alph, "Collision", -0.99)

function alph(i, x, y, surround, nt)

      if tpt.get_property("tmp", i) == 0 then
      local a = (math.random(360)-1) * 0.01745329;
      tpt.set_property("life",680,i)
      tpt.set_property("vx",2*math.cos(a),i)
      tpt.set_property("vy",2*math.sin(a),i)
      tpt.set_property("tmp", 1, i)
   end
end

tpt.element_func(ALPH, tpt.el.bran.id, 1)

Sorry, i dont know how to put in in the red box.

end
end
tpt.element_func(alpha, alph, 1)

you were making that update for bran not your particle so i put in the particle name instead of tpt.el.bran.id and it works. so the lesson here is to make sure the update your making is actually for the particle you want it to be for. jacob1 just made that example to show how it worked.

laggy but cool prot/neut type deco, turns on with 'P' in the top right corner

local alph = elements.allocate("Alph", "alph")
local deco = {}
elements.element(alph, elements.element(elements.DEFAULT_PT_ELEC))
elements.property(alph, "Name", "ALPH")
elements.property(alph, "Colour", 0xFFDD00)
elements.property(alph, "Description", "Alpha particle.")
elements.property(alph, "Weight", -1)
elements.property(alph, "HeatConduct", 251)
elements.property(alph, "Temperature", 295.15)
elements.property(alph, "Properties" , 0x10410)
elements.property(alph, "AirLoss", 1)
elements.property(alph, "Loss", 1)
elements.property(alph, "Collision", -0.99)
function alpha(i, x, y, surround, nt, s, n)
if tpt.get_property("tmp" , i) == 0 then
local a = (math.random(360)-1) * 0.01745329;
tpt.set_property("life",680,i)
tpt.set_property("vx",2*math.cos(a),i)
tpt.set_property("vy",2*math.sin(a),i)
tpt.set_property("tmp", 1, i)
end
table.insert(deco, i)
end
tpt.element_func(alpha, alph, 1)
function draw()
if sim.prettyPowders() == 1 then
  for i,v in ipairs(deco) do
   local Atype = sim.partProperty(v, sim.FIELD_TYPE)
   if Atype == alph then
    local x = sim.partProperty(v, sim.FIELD_X)
    local y = sim.partProperty(v, sim.FIELD_Y)
    tpt.drawpixel(x,y+1,32,224,255)
    tpt.drawpixel(x+1,y+1,153,0,0)
    tpt.drawpixel(x+1,y,32,224,255)
    tpt.drawpixel(x,y,153,0,0)
   end
  end
end
end
tpt.register_step(draw)

wow I still don't get it

jward212

what don't you get?

What it does. How it changes the properties of an element.
