Hey,

I've got this structure for CBaseCombatCharacter. How do i access its offsets? I need to access m_bPreventWeaponPickup to check if weapon pickup is prevented.

Would this be the appropriate way? I was trying out FindDataMapInfo, but couldn't figure how to check each slot?

PHP Code:

int offset    =    FindDataMapInfo(client, "m_bPreventWeaponPickup"); 


PHP Code:

00000000 CBaseCombatCharacter_data struc ; (sizeof=0x284, align=0x4, copyof_1628)

The offsets you've provided aren't absolute; CBaseCombatCharacter is a subclass of other classes with properties.

There is a datamap dump for L4D2 here. m_bPreventWeaponPickup is a named property (at offset 6105); just use GetEntProp(client, Prop_Data, "m_bPreventWeaponPickup") to access it.

For properties that aren't defined as a netprop / dataprop, you'd probably opt for offsets relative to a named property (e.g., to access m_weaponIDToIndex you'd call FindDataMapInfo to get the offset for the named property m_impactEnergyScale, add 0x04, then use GetEntData to read it -- well, you'll probably need to read out the bytes as a string since it's a 38-byte char array).

It sounds like you're using this as reference, which has a comment right above your struct stating the offset is 6092 bytes relative to the CTerrorPlayer entity address.

Hmm so how would I switch between slots?

Thanks for your input as always. You have been a real help.

I'm not sure what "slots" refers to in this context. Weapon slots?

I don't have a deep-level understanding of L4D2 (only played it casually), but if m_bPreventWeaponPickup changes depending on the weapon, you'll have to continue browsing through the assembly for modifications to that offset (6105 being 17D9 in hex).

I believe you can set a watchpoint on the memory address as well in GDB; have never done it myself, though.

Yeah I was referring to weapon slots. Guess I got to stare at the disassembly some more.
