TNT Particles Engine for Gideros Mobile SDK PREVIEW 2 - Coming Soon -

GregBUG · February 2012

hi guys!!!

after some days of headaches and coding, coding, coding ...
finally my particle engine is almost done...

I'm really proud to show you the 2nd preview of my particle engine
(codename "TNT Particle Engine")

my main goal is not a supercharged/sexy/candy engine but a fast, light and easy to use engine
optimized for realtime mobile games...
(got 59fps on my galaxy s, 59 fps on huawei u8650 armv6 600Mhz)
not yet tested on iOs devices... sorry...

i'm really amazed by Gideros Speed... and my engine speed

the key features are:

- unlimited emitters
- unlimited particle definitions
- every emitter can have unlimited particle groups
- global and local coordinate system (for emitters/particles)
- Particles speed Morph
- Particles color Morph
- Particles size Morph
- Particles alpha Morph
- Particles rotation Morph
- Particles directions Morph
- Particles displacement
- controllable particles loops (infinite or user defined)
- Particles gravity (not yet implemented)
- raise events when emitter start, ends, etc (not yet implemented)

- user definible effects... (not yet implemented)
- and many more... (not yet implemented ??)

hope you like it
here is the video:

....coming soon....

next days i'm adding missing features, cleaning code, writing some other examples and writing simple docs
then i'll release it!

ciao ciao
Gianluca.

Looking good.

moopf · February 2012

Very interested in this. It's a given that most games would have a requirement for particles and I really don't want to have to roll my own if at all possible.

Sergeyka · February 2012

Gianluca, it is cool! =;

ar2rsawseen · February 2012

That looks really awesome.

So any restriction on compatabilities? What Gideros Studio supported, are there any paltform restrictions?

Plans for licensing, pricing?

gorkem · February 2012

$ whois tntparticleengine.com
No match for "TNTPARTICLEENGINE.COM".

\:D/

GregBUG · February 2012

@all
thanks guys for the positive feedback!!!

@ar2rsawseen
developed with gideros studio beta8 and 2012.2 no platform restrictions.

for now I have no idea if it will be free or not!!! :-/ (but i prefer donation-ware)
i developed it only for fun! (i'm not a professional developer in real life i'm a computer/ repair technician).

@gorkem

btw: i like your Signature!!!

Magnusviri · February 2012

Wow, very cool. That's really impressive "only for fun".

moopf · February 2012

@GregBUG, if this work well, I'll be only too happy to donate if that's the route you go down. It will save me lots of time.

atilim · February 2012

yay! looks great

zakkwylde · February 2012

GregBUG, that is WOW!. I love the space explosion.

Well done!

GregBUG · February 2012

quick update:

just added gravity to particles engine...

tonight new video with example 5 "magic funtain"

ar2rsawseen · February 2012

Can't wait to see that

GregBUG · February 2012

here is it...
example 5 "magic funtain" (with and without gravity) 220 particles in action at 59fps!

now go to bed!

tomorrow: raise events! and clean code (try to optimize more)

ciao ciao
Gianluca.

ndoss · February 2012

This looks very nice ... I'm pretty excited!

GregBUG · February 2012

another quick update:
Color Points example:

GregBUG · February 2012

today update worklog:

alpha morph in/out + displacement and colors ;;) (150 particles)

beta testers are you ready ?

(eh! eh! eh!)
need to add some 3 little effects and it's ready for beta test.

hope to finish this week-end!!!
stay tuned!!!

chipster123 · February 2012

Greg, this is beautiful. Can't wait.

moopf · February 2012

I'm ready! Can't wait to test this

GregBUG · February 2012

i'm working on class interfaces...
and i try to semplify at maxiumus the use of engine...

this is the sources of last example:

----------------------------------
 
-- Create simple particle with random speed and
-- random direction.
 
 
-- init program
application:setBackgroundColor(0x000000)
application:setKeepAwake(true)	
-- load graphics
local particleGFX = (Texture.new("pTexture.png"))								-- load particles sprite
 
-- create new emitter called emitterTest_1
emitterTest_1 = CEmitter.new(160, 30, 90, stage)							-- create emitter positioned at x 160 y 240 direction 0 degree
 
particleTest_1 = CParticles.new(particleGFX, 150, 1.5, 1.5, "alpha")				-- create 15 particles, maxLife 1 sec, max delay 1 sec using alpha blending
-- create particles...
particleTest_1:defineRandomColors(0, 0, 0, 255, 255, 255)
particleTest_1:defineSpeed(150,390)										-- define particles speed min 150 pixel/sec max 350 Pixel/sec
--particleTest_1:defineDirection(0, 45)										-- define random particles direction from 0 to 360 angle
particleTest_1:defineDisplacement(320, 0)
particleTest_1:defineSize(1, 2.5)
particleTest_1:defineAlpha(0, 20)
--particleTest_1:setAlpha(0)
particleTest_1:defineAlphaMorphIn(255, 0.4, 0, 8)
particleTest_1:defineAlphaMorphOut(0, 0.3, 0.7)
 
-- assign particles...
emitterTest_1:assignParticles(particleTest_1)								-- assign particle to emitter
 
-- start emitter
emitterTest_1:start()														-- start emitter
 
function onEnterFrame(event)
	emitterTest_1:update(event.deltaTime)									-- update emitter every frame...
end
 
stage:addEventListener(Event.ENTER_FRAME, onEnterFrame)						-- add event listner "onEnterFrame"

what do you think ?
it's easy or i need to semplify more ?

moopf · February 2012

First thought is that I like that emitters and particles are separate like this - I presume it's easy to change the particles used by the emitter once the emitter is setup?

The only thing that seems a little odd is that you need to add an event listener to update the particles - surely the particle system should take care of that?

gorkem · February 2012

Easy - so that one can implement in his own screen in 5 minutes; detailed so that one can change many parameters to suit her needs.

GregBUG · February 2012

@moopf

yes emitter and particles are separate.
you can assign as many particles definition to emmitters and you can have many emitter you like.

for now at run time you can change emitters postition, angle (and all attached particles) and for particles
position (local to emitter) rotation, direction, speed. but i plat to add major control for every particle.

The only thing that seems a little odd is that you need to add an event listener to update the particles - surely the particle system should take care of that?

yes, you need to add

emitterTest_1:update(event.deltaTime)
in your main game loop (for every emitter in the scene)
i plan to add something like "emitter:updateAll(deltaTime)"
to update all the active emitters in the scene. but i'm not sure.

now thinking to add the option to uptade emitters by particles system.
you think is better ?

@gorkem.
thanks i try to make as easy possible. but i need you feedback and tips.

moopf · February 2012

Oooh, multiple particles per emitter - I like that a lot! You're really ticking all the boxes on functionality there.

I do think that the particle system should update the emitters, yes. It's generally a good thing to keep the updating enclosed in the "black box", so as a user I just use start(), stop() etc. to control the particles - I shouldn't have to add my own updating setup once I've done start(), the particle system should take care of that for me. Much more user-friendly.

yes you are right... :-bd

mmm... new work for me @-)

ok. i try to add this... (tonight because now i'm at work!!!)

[edit]
just added!!
thanks @moopf for the tips!

now sources look like this:

emitterTest_1:assignParticles(particleTest_1)								-- assign particle to emitter
 
-- start emitter
emitterTest_1:start()

and you can stop, hide, pause with emitterTest_1:stop(), pause(), etc..

ciao!

GregBUG · February 2012

here is an apk of last example...

if some one can test and feedback on performaces... (really interessed on cheap devices)
(sorry only android!)

here is it:

moopf · February 2012

Works a treat here on my Acer A100 tablet (it's a cheap 7" tablet)

GregBUG · February 2012

@moopf thanks.
(hey your tablet is a1GHz dual-core Nvidia Tegra 2 processor) it's very powerful!!

moopf · February 2012

haha, is it? I just got the cheapest Android tablet I could that was 7" (to test a different screen density and ratio). Got it from Amazon, about 250 GBP if I remember rightly. It's OK, it's not as smooth as the iPad and the battery life is rubbish

I didn't want anything powerful, looks like I didn't pay enough attention to specs!

ar2rsawseen · February 2012

Got one LG Optimus One (P500), the cheapest you can get, but don't have it on my hands right now (been sick and home all week) so probably will get my hands on it next week, if you're still interested in feedback.

GregBUG · February 2012

@ar2rsawseen

yes i'm interested. when you can test please tell me the results.

thanks.
Gianluca.
