Entity type

[arielnmz]

Okay, i've got this function (made by wesser) which returns the colision point, distance and ENTITY (struct) of the "thing" it collided with... but, is there a way to know whether it is a solid/ped/car/object...????

 

This is such function: (getCollisionBetweenPoints)

Thanks!!!

Once you've stored the entity address, there are a few ways to get the type of entity back from it. As I explained in a similar topic... http://gtag.gtagaming.com/forums/index.php?showtopic=622

[arielnmz]

so, for now, the best solution is to check into the addresss pools.. right???

[Deji]

Or to check the vtable adress, which would be faster but less compatible.

[arielnmz]

okay... I found this:

 

 

CPlaceable (vmt=0x863C40, size=0x18):  CCamera (vmt=0x8630E8, size=unknown)  CEntity (vmt=0x863928, size=0x38):      CBuilding (vmt=0x8585C8, size=0x38)          CTreadable (vmt=0x8639B0, size=0x38)      CDummy (vmt=0x8638C0, size=0x38)          CDummyObject (size=0x38)          CDummy_86C198 (vmt=0x86C198, size=unknown, unused)      CPhysical (vmt=0x863BA0, size=0x138)          CObject (vmt=0x866F60, size=0x17C)              CHand (vmt=0x866EE0, size=0x18C) // actor's hand in cutchenes              CProjectile (vmt=0x867030, size=0x17C)              CCutsceneObject (vmt=0x868A60, size=0x19C)          CPed (vmt=0x86C358)              CCivilianPed (vmt=0x86C0A8, size=0x79C)               CCopPed (vmt=0x86C120, size=0x7C4)               CEmergencyPed (vmt=0x86C200, size=0x79C)               CPlayerPed (vmt=0x86D168, size=0x7A4)           CVehicle (vmt=0x871E80)              CAutomobile (vmt=0x871120, size=0x988)                  CHeli (vmt=0x871680, size=0xA18)                  CMtruck (vmt=0x8717D8, size=0x99C)                  CPlane (vmt=0x871948, size=0xA04)                  CQuad (vmt=0x871AE8, size=0x9BC)                  CTrailer (vmt=0x871C28, size=0x9F4)              CBike (vmt=0x871360, size=0x814)                  CBmx (vmt=0x871528, size=0x838)              CBoat (size=0x8721A0, size=0x7E8)               CTrain (vmt=0x872370, size=0x6AC)

 

 

Specifically this caught my attention:

 

 

CPed (vmt=0x86C358)              CCivilianPed (vmt=0x86C0A8, size=0x79C)               CCopPed (vmt=0x86C120, size=0x7C4)               CEmergencyPed (vmt=0x86C200, size=0x79C)               CPlayerPed (vmt=0x86D168, size=0x7A4) 

 

 

And I found this, too:

 

 

PedestriansGeneral0xB6F5F0 - Player pointer (CPed)0xB7CD98 - Player pointer, direct offset to the ped pool start (CPed)0xB74498 - CPeds maximum number (normally 140)0xB74490 - Contains a pointer to a main struct belowThis struct:+0 = Contains a pointer to the first element in the pool+4 = Contains a pointer to a byte map indicating which elements are in use+8 = [dword] Is the maximum number of elements in the pool+12 = [dword] Is the current number of elements in the poolEach ped object is 1988 (0x7C4) bytes.

 

 

I think I need to compare the address of the entity with the CPed vmt... what I dont know is how ...

 

And for the second method, Should I do a "for" from 0 to the current number of elements in the pool, then see if the address is present?

 

I think I've got the idea, but I dont know how to do this specifically...

[Deji]

Read the address of the entity pointer to get the virtual table address...

 

0A8D: [email protected] = read_memory [email protected] size 4 virtual_protect 0 // [email protected] is the entity struct

 

[arielnmz]

and then compare it with this?

 

 

CPed (vmt=0x86C358)CCivilianPed (vmt=0x86C0A8, size=0x79C) CCopPed (vmt=0x86C120, size=0x7C4) CEmergencyPed (vmt=0x86C200, size=0x79C) CPlayerPed (vmt=0x86D168, size=0x7A4) 

 

 

Right? (something like: [email protected] == 0x86C358) To see if it is a ped...

 

And what about the other method? the one of the data pools?? you it was more "sensible" and "compatible"...

[Deji]

[arielnmz]

thanks, deji, i just took the first three digits of the VMT of the obtained entity then compare them if they match with the first three digits of the VMT type I want to handle... that did the trick ... btw how to call the function or how to get the id of the CEntityInfo type that you posted on that thread??
