This look great!

Some suggestions:
Add particles for every node (maybe a group no_particles to prevent it) and use the textures of the node
Make the particles a bit slower (they fly too far IMO)
Remove the selectionbox of the particles
Smoke particles spawn in fire

awesome... cool effects....

+1 regarding smoke, and please PLEASE make it look something like smoke instead of just pixels, and make it more abundant than in the old mod (sorry sfan :-) ).

Do you have a texture you would like see used?

pulled, thanks for the code improvements

Does this provide particles for water or lava as well? It would be neat to see splashing or small magma pieces jump up.

by **Mito551** » Mon Sep 17, 2012 15:20

a little suggestion: maybe make them disappear faster?

by **VanessaE** » Mon Sep 17, 2012 16:41

Odd bug: dig up a piston or sticky piston from mesecons. The particles become some odd color and flicker like crazy.

i'm not the cornernote, but nope, it doesn't. splashing seems easy to do (as i see it), but lava stuff... a suggestion^^

Suggestion for all mesecon nodes:

Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.

Code: Select all: groups = {no_particles=1}

Particles dont fit into the mesecons mod.

This looks great!
What about particles while digging? Or at least particles on punch?

by **VanessaE** » Tue Sep 18, 2012 05:00

There's no callback/function that can tell if the player is digging (or even just swinging at air), so this isn't really possible yet.

Yeah, we talked about checking the health of the node once, on IRC, but it sounded like a cumbersome hack for little functionality. I was just hoping that maybe a function to tell if the player is digging had been included in the new release...

Anyway, at least it could be done for punches...

looks cool!!

by **Iqualfragile** » Wed Sep 19, 2012 20:17

PLEASE: tune down the amount of particles spawned to 5 or random(7,3)
i have chaned it on my server because it just killed the upload.

by **cornernote** » Wed Sep 19, 2012 21:40

That's odd. It works really fast for me. Is your computer oldish?

Has anyone else had an issue because of too mant particles?

by **Iqualfragile** » Wed Sep 19, 2012 21:43

let me cite: "the upload."
so its network-based (crappy upload…)

I installed doorsplus, but I could not replicate the issue. From your log it says you broke door A when it was closed. I broke door A and B, open and closed, no crash.

I did look at the code where it crashed, and added a line that may fix it. Please let me know if you still have this issue.

i have removed the mod, so its an unknown block

by **cornernote** » Thu Sep 20, 2012 22:22

Ahh, I see. Please try latest git. I fixed some unknown block dig issues recently.

I got this just now:

Code: Select all: 23:25:35: ERROR[main]: ServerEnv: Trying to store id=73 statically but block (3,-1,0) already contains 49 (over 49) objects.

I think it's because a lot of gravel fell and it landed on a torch... it might be blocking the torch particles (although I'm not certain it's that).
Also, I'm not sure if the "Forcing delete" errors are related. That might be something from the simple mobs mod.

by **cornernote** » Fri Oct 05, 2012 02:53

thanks leo_rockway,

i just added fix to stop it from killing the server if that happens

Heres a backup of the mod: http://ompldr.org/vZzVseQ/minetest-particles.zip
(The number of particles are changed to 7-9, but it looks better)
