Bullet Physics 2.64-RC3 for PSP

[Drakon]

Hi. I'm creating my new game and I just wanted to ask if someone was trying or was able to build Bullet physic engine for psp?

I was able to build only version 2.61 but had some errors with linking :/

Sooo anyone?

EDIT
Here is Bullet Physics library 2.70 for psp - http://drakon.xxl-web.pl/wp-content/bullet-2.70_psp.rar

It comes with simple demo1 - floor and box(press X to add new box),demo2 - soft body(working now ^^).
Tested only on psp slim.

Can you paste your errors?

[Drakon]

I don't want to junk this thread so maybe here:

Spoiler for errors...:

I compiled Bullet library - get 3 files libbulletmath.a libbulletcollision.a libbulletdynamics.a , now I want to make simple test app but when I add some objects to the code then I got linking errors at the end.. :/

Of course I added lbulletmath -lbulletcollision -lbulletdynamics to the make file...

Spoiler for makefile:

hmm maybe building library was wrong... ehh grrr... or because i'm using windows and precompiled sdk...

Where's Bullet library?

[Drakon]

Where's Bullet library?

If you want main site it's here : http://www.bulletphysics.com/

and version 2.64-RC3 for psp is here: http://drakon.xxl-web.pl/wp-content/...64-RC3_PSP.rar

Package contains sources of library with make file and simple demo.

Warnings:
1. Demo tested on slim psp - I think that it will not work on fat...(maybe someone will change the code).
2. In file :btDefaultCollisionConfig uration.cpp - I chaged

#define DEFAULT_MAX_OVERLAPPING_PAIRS 1024
#define DEFAULT_STACK_ALLOCATOR_SIZE	(5*1024)

from

#define DEFAULT_MAX_OVERLAPPING_PAIRS 65...
#define DEFAULT_STACK_ALLOCATOR_SIZE	(5*1024*1024)

so it can effects later but anyone can change this.

Compiling library:
1. Unpack .rar file, go to bullet-2.64-RC3\src folder and type make or use compile.bat if you are using windows.
2. Wait...
3. You should get 3 files : libbulletmath.a, libbulletcollision.a, libbulletdynamics.a
4. Copy them to the pspsdk\psp\lib
5. Copy all .h and subfolders with files to pspsdk\psp\include

Compiling demo:
1.Go to the demo folder and type make or use compile_slim.bat if you are using windows.

Later I will attack new version (soft bodies,soft bodies....)
Have a nice day:>

[dan369]

Nice job porting the lib , i'll compile it now. (I'll test on my PHAT (the demo) to see if it works)

[Drakon]

Me again - I have managed to build version 2.70 but >2.70 is no go... errors while compiling library.

Soft Body demo is working ^^.

[cheewongken]

anyway, good job! =D . looks like not gonna be updates for Jellycar for a while.... XD

[MK2k]

Good work Drakon :)

[Drakon]

Thanks and yep, currently not enough time for JellyCar...
Also I'm wondering about performance with heavy use of vfpu math - I must test this

[slasher101]

dam thats my fav game!
