Can you count particles with lua? Like a variable, such as "ParticleCount" or something.

What sorta particles do you wanna count?
If you just want all do
local count = 0
for particle in MovableMan.Particles do
count = count + 1
end

No... that does nothing.... I don't think so at least. That's just increase count by one every Sim update..

More like increases count by one on every loop through particles.

But it keeps increasing and never stops...

If you declare the variable "count" in the update function, it'll reset the count to 0, then recount all the particles.

I don't know much Lua, so I'm taking an educated shot in the dark, but this is my pov:

If count > 50 then
count = count -1

You guys are over complicating things . This is the answer you seek:

MovableMan.Particles is a Lua 'table'. Each element of the table is a particle. To get the number of elements in a Lua table, you use the # operator. http://lua-users.org/wiki/TablesTutorial

Try typing this into the console in game and see what I mean:

Knew I forgot something.
Revised code:

Thanks for showing me, but can you only print how many particles there are that pass certain requirements? It'd seem printing that would print the total number of partciles no matter the circumstance.

Edit: Kyred, it just gave me an error about trying to find the length of "Particle".

Well I'll be fudge. It really isn't a Lua table. It's a function o_O

However, MOPixels and MOSParticles are tables, so it should work for those.

If you want to add in circumstance (ie. if statements), then you would have to use a for loop like mail2345 was using.

MOPixels and MOSParticles seem to only be returning how many scripted entities of that type there are, if I remember correctly.

Like can you do "MovableMan.Particles closer than 50 pixels"? As in find how many are less than 50 pixels away?
