Hi! guys!
after many hours of work finally i’m almost ready to release my new Library for Gideros SDK.
TNT Native Collision Engine a native (c++) plugin for collision detection.
Why you should be use this libs when Box2d do the same things ?
first i need to say one thing:
*** if you need more accurate collision detection with physics interaction then my lib is not for you. ***
i’ve made this libs for *simple* but *FAST* (really FAST) collision detection to use in my next project.

TNT Collision can now handle some kinds of collision like:
point->box, point->circle, point->oriented Box
circle->circle, circle->box, circle->oriented Box
box->box, oriented box->oriented Box
with any handle point.
i hope to release in next 2-3 days.

(as soon as i fix iOS compile problems)
stay tuned!

Hi GregBug - I'm really excited about this. Good luck with the project.

I'm really looking forward to this release!

Looks great, can't wait to try it out!

@gregbug
The difference you show is really amazing. Smooth as it should be.
Are you using sounds as well - a sound played when objects collide?
In normal Gideros, I get a stutter whenever a sound is played.

BlastByte

@bernard
Are you using .mp3s for your sound effects?

This has been known to cause stuttering and the advice is to use .wav - http://www.giderosmobile.com/forum/discussion/331/what-is-the-best-sound-format

I haven't tested playing many sounds at once, would be interesting to see what the result would be in a case like this video. And I second the impressive performance increase displayed!

GregBUG

thanks @all

i'm almost ready to release my plugin (with demo sources)
so we can test ! for audio

bernard

@BlastByte
Yes I was. I actually has a .wav file but for some reason, at that time, Gideros refused to upload it to the ios player so I changed it to mp3 and it uploaded with stutters. Today I changed it to a .wav again and now it uploaded fine and ran with NO STUTTER.

Thanks for reminding me.

@bernard what do you think changed between two uploads? Any config modifications ?

@bernard what do you think changed between two uploads? Any config modifications ?

Possibly a version change. Not sure of the old version number but I remember that everytime I ran the game I received an error that the .wav could not be found, even though it was included in the project. I even manually copied it to the iPad but still the error. When I changed it to a .mp3 it uploaded immediately and no error.

Possibly the new version fixed something in either Gideros or the iOS player, can't say which. Anyway .wav works fine now and no stutter.

@bernard, if it is related to a .wav, I think @Atilim has fixed it, so it should be the new version, there was an issue that he had promised would be fixed i the new version. Haven't upgraded the build, but if you say the problem is solved, then it must have been the fix.

Hey @GregBug,

I'm going through the examples, and it looks like you've done an amazing job here!

I'm a little unclear as to how much heavy lifting your engine does though. It looks like you have a simple loop that goes through and tests each object on screen against every other object on screen for the box to box collisions, and yet it's running very smoothly. I assume your engine is able to discriminate between objects that are close together, and those that are not?

I'm curious, as I'm trying to decide on how to implement this into a project I'm working on.

@joelghill thanks for try my lib!

yes the engine evaluate only objects that are very close together and ignore the rest.

BTW on what device are you testing TNT Collision?

joelghill

I was testing on the desktop player (osX), but I wil be using it on a Samsung Galaxy S2 once I have time to use it in a project.

SinisterSoft

@GregBug Are you going to release a new version of this library with x86 Android libs?

@aw2rawseen Maybe it would be good if something like this was in an official plugin?

GregBUG

@SinisterSoft
yestarday i sent and email to atilim.
i need to "resetup" my pc for restart develop TNT engine 2.

last year i used qt Nokia (suggested by Atilim)
but now they are not avaibles anymore.

so my question is...
what is "suggested/best" setup for develop/compile plugins (arm/intel/desktop) now ?

As soon as i "resetup" my pc i release a new version on TNT Collision with x86 lins included.




i'm was "out" from gideros for a while... but now i need to recuperate lost time...
B-) B-) B-)

@GregBUG for android all you have to do is to add
x86 to APP_ABI in Application.mk file like this:

APP_ABI := armeabi armeabi-v7a x86

For desktop I used QT Creator, which seems to be quite awesome

@ar2rsawseen Thanks!

SinisterSoft

@ar2rsawseen Is adding MIPS support just as easy?

ar2rsawseen

@SinisterSoft unfortunately not, MIPS need to account for difference between Big and little endianness

SinisterSoft

np, only a few mips devices out there I think.
