Varbuut kaadam ir kaada ideja kaa tokamakaa var konstateet kad divi objekti ir saduurusies? Vajag preksh skriptu ainaam (mol, pogu spiezu, bet dirvis ta neveras). Protams variants ir uzkabinaat triigerim sensoru un cekot kas notiek, bet ar lielaakiem objektiem tas neder (vai piem, saujot pa durviim).
anyway - varbuut ir kaads variants kaa dabuut no tomaka koliizijas infu? |

callbacki
uzseto callbacku un shamais tix izsaukts katru reizi kad objekti sadursies
void SetCollisionCallback(neCollisionCallback * cb);
typedef void (neCollisionCallback)(neCollisionInfo & collisionInfo);
struct neCollisionInfo
{
neByte * bodyA;
neByte * bodyB;
neBodyType typeA;
neBodyType typeB;
neGeometry * geometryA;
neGeometry * geometryB;
s32 materialIdA;
s32 materialIdB;
neV3 bodyContactPointA; // contact point A in body space of A
neV3 bodyContactPointB; // contact point B in body space of B
neV3 worldContactPointA; // contact point A in world space
neV3 worldContactPointB; // contact point B in world space
neV3 relativeVelocity;
neV3 collisionNormal;
};

uff.. nepretendeeju uz preciizu kodu bet naff laika taisiit testa piemeeru
nodefineejam funkciju kas sanjems izsaukumu briidii kad saduraas divi obketi
| Code: |
void CollisionCallback(neCollisionInfo & collisionInfo){
//principaa sheti no collisionInfo var dabuut infu par objektiem kuri ir saduurushies
MessageBox(0, "Objekti saduuraas", "Ar adataam ;)", MB_OK);
};
|
peec tokamaka inicializaacijas
bet veelams pirms objektu radiishanas pasakaam tokamakam ka briidii kad objekti saduraas ir jaaizsauc dotaa funkcija
| Code: |
SetCollisionCallback((neCollisionCallback)CollisionCallback);
|
principaa ja shitaa izdariisi tad vajadzeetu izlekt messageboxim katru reizi kad objekti saduraas.

| a tur ir tipa ir Default_Callback(...)? lai tipa panjemtu tikai taas koliizijas kas ir starp diwiem nepiecieshamajiem objektiem un paareejos lai tokamaks pats tiek galaa. |

ok, pameginashu...
...principaa lai callbacks darbotos vajag to uzsetot caur neCollisionTable ->Set(a, b, neCollisionTable::RESPONSE_IMPULSE_CALLBACK);
kur a un b objektu ID.
Peec defaulta tur staav tikai neCollisionTable::RESPONSE_IMPULSE
taa kaa callbaks nedarbojas.... |

| Sanaaaca, tikai ne paaraak eerti ir cekot kurs objekts iisti ir saduuries no vissiem uzsetotajiem, iespeejams naaksies taisiit kaut kaadu atsevisku registru kur atrodas tie objekti kam buutu jaaatbild uz koliizijaam un jaameklee tikai starp tiem nevis starp vissiem sceenas objektiem. |

hei, laba ideja.
te ir princips kaa tas darbojas:
| Code: |
//geometrijas classe (to var saukt arii par entiitiju vai piem. par GO (game object), whucares)
class GameObject
{
public:
//notikums kas tiek izsaukts koliizijas briidii
void OnCollision()
{
MessageBox(NULL,"GO has collided with something.","Yahoo...",MB_OK);
}
//Init object
void Init()
{
//izveido body un geometrijas;
//....
//uzseto pointeri uz so passhu klassi
body->SetUserData((unsigned int)this);
}
neRigidBody* body;
};
//tagad kaut kur kodaa (velns vin zin kur?!)
//defineejam collision callbacku
void myCollisionCallback(neCollisionInfo & ci)
{
//piemeera vienkaarsiibas noluukos es pienemu ka intereseejosais
//objekts ir tiesi bodyB, te buutu jaaceko abi (bodyA un bodyB)
if(ci.typeB == NE_RIGID_BODY)
{
neRigidBody* rb = (neRigidBody*)ci.bodyB;
if(rb)
{
GameObject* obj = (GameObject*)rb->GetUserData();
if(obj)
{
//nu luuk pilniigi neatkariigi no GameObject atrassanaas vietas ir iespeejams iedarbinaat taa
// koliizijas eventu //galvenais ir tikai to initieet!
obj->OnCollision(/*seit buutu jaanodod infa par koliiziju*/);
}
}
}
}
|
nu kat kaa taa!
thanx _laaci |

ideja jau neslikta, bet ir arii citi, nedaudz aatraaki risinaajumi
un, btw, tokamak taapat nav vieniigais solution, vienalga visam paari staav havok/ipion, nesakiet tikai, ka nav iespeejams to nekur dabuut :lol:
--------------------------------------------------------------------
vispaar vai nu shodien vai riit es iepostoshu savu variantu koliizijas noteikshanai, kuru es izmantoju arii TZP. vnk varbuut kaut kur noder  |
