Quark system

Contents

Quark system is an implementation of Dependency injection. At the start of game quark system table (DI container) is populated with Quark instances, which are references to all classes in the game (see tpp::gm::QuarkInitialize, 1505 entries total). These instances are reused later like this (pseudocode):

// tpp::gk::GimmickUtility::EnableDynamicCoverPoint

auto container = fox::GetQuarkSystemTable();
container["GimmickUtilty"]->SetSomeFlag(param_1, param_2 + 1.5, param_3);

Decompiled form:

pQVar1 = fox::GetQuarkSystemTable();
(**(code **)(**(longlong **)(*(longlong *)(pQVar1 + 0x98) + 0x1b8) + 0x30))
            (*(longlong **)(*(longlong *)(pQVar1 + 0x98) + 0x1b8),param_1,param_2 + 1.5,param_3);

QuarkSystem table is a hash table, all elements have fixed positions and consistent across exe versions. 0x98 is a bucket, 0x1b8 is an offset in that bucket, 0x30 is an offset for SetSomeFlag function in GimmickUtilty vtable. Keys are strings encoded with StrCode64 (see Hash Wrangling). Bucket, table offsets and container keys are not documented.
