1. When the output wrapper to version 6?
2. In this version of the wrapper is missing a lot of commands, and in some procedures do not match the number of parameters. The author has no plans to add a brief description of the structures and commands?
3. What exactly does this function: cpSpaceHashEach (*space\activeShapes,@DrawShape(),#Null) ?

Little things will not ask, I will try to understand them myself.

2) Without some procedures you can do if you know the description of the structures .But when some have additional parameters, it is not clear that there sent. I wanted to try a code, taken from the forum and could not implement it for lack of commands and mismatches.

Code: Select all

// velocity of the two surfaces in relation to the collision normal at the collision point
static inline cpFloat
hit_velocity(cpBody *a, cpBody *b, cpVect p, cpVect n){
   cpVect r1 = cpvsub(p, a->p);
   cpVect r2 = cpvsub(p, b->p);
   cpVect v1_sum = cpvadd(a->v, cpvmult(cpvperp(r1), a->w));
   cpVect v2_sum = cpvadd(b->v, cpvmult(cpvperp(r2), b->w));
   
   return cpvdot(cpvsub(v2_sum, v1_sum), n);
}

// This is a pre-solve callback
static bool
bumpSoundCallback(cpArbiter *arb, cpSpace *space, void *unused)
{
   cpShape *a, *b; cpArbiterGetShapes(arb, &a, &b);
   cpContact *contacts = arb->contacts;
   
   const cpFloat min = 10.0f;
   const cpFloat max = 300.0f;
   cpFloat nspeed = cpfabs(hit_velocity(a->body, b->body, contacts[0].p, contacts[0].n));

   if(nspeed > min){
      ALfloat volume = fmax(fminf((nspeed - min)/(max - min), 1.0f), 0.0f);
      playSound(bumpSound, volume, 1.0f);
   }
   return TRUE;
}

Here
3) cpvsub, cpvmult - need 3 parameters instead of 2. What are they?

Were you have this example source?

1)This code is taken from the chipmunk-physics forum. Posted some guy with a nick slembcke.

Thank you. Somehow I figured out that code.
2) There were link errors due to cpfabs, cpfmax, cpfmin - had to throw them away.
3)In general, it seems I am close to completing a wrapper for your wrapper.

Fine. You are not alone

Polink errors?

And who else mpz?
I'm writing it for my little game, so it will not be universal.

Polink errors?

POLINK: error Unresolved external symbol 'cpfabs@@YANN@Z'
POLINK: error Unresolved external symbol 'cpfmax@@YANN@Z'
POLINK: error Unresolved external symbol 'cpfmin@@YANN@Z'

Test program today, changed all the settings. The slowdown started after 1000 (small) objects, that I was not happy. Hoped for more. In connection with the question: cpSpaceResizeActiveHash shure works? I tried different settings, even removed it, no effect.

Post your code and I can say more

Sweet. But I think it is not using PureBasic. Right?
