[Solved] Call a function by the pointer from FunctionTable

kadet.89 · **Author**

I have these functions from datamaps:

DEFINE_THINKFUNC( Detonate )

Code:

CBaseCSGrenadeProjectile - hegrenade_projectile
- InitializeSpawnFromWorld (Offset 0) (Input)(0 Bytes) - InitializeSpawnFromWorld
- CBaseCSGrenadeProjectileDangerSoundThink (Offset 0) (FunctionTable)(0 Bytes)
- m_hThrower (Offset 1292) (Save)(4 Bytes)
- m_bIsLive (Offset 1265) (Save)(1 Bytes)
- m_DmgRadius (Offset 1268) (Save)(4 Bytes)
- CBaseGrenadeSmoke (Offset 0) (FunctionTable)(0 Bytes)
- CBaseGrenadeExplodeTouch (Offset 0) (FunctionTable)(0 Bytes)
- CBaseGrenadeDetonateUse (Offset 0) (FunctionTable)(0 Bytes)
- CBaseGrenadePreDetonate (Offset 0) (FunctionTable)(0 Bytes)
- CBaseGrenadeDetonate (Offset 0) (FunctionTable)(0 Bytes)

I get a void* from CBaseGrenadeDetonate (and it's not nullptr), is there a way to call the function using the pointer?

PHP Code:


			
DEFINE_THINKFUNC( Detonate ),

virtual void Detonate( void );

I tried to do it like this, but it crashes the server:

PHP Code:


			
typedef void (*Detonate_pointer)();



void* pointer = ...



((Detonate_pointer)pointer ())();

PHP Code:


			
void* pointer = ...

CBaseEntity* ptr = ...

reinterpret_cast< void(*)(CBaseEntity*) > (pointer ) (ptr );

UPD:
I got inputfunc_t field value from typedescription_t of the "CBaseGrenadeDetonate", I gues that should be the correct funcion pointer, but have no idea ho I can call it
