Raw Blame History

//========= Copyright Valve Corporation, All rights reserved. ============//
//
// Purpose:
//
// $NoKeywords: $
//
//=============================================================================//
// ---------------------------------------------------------------------------------------- //
// This is a datatable test case.
// It is run in debug mode when the engine starts to catch any bugs in datatable code.
// This can also serve as a simple example of how datatables work separately from the
// intricacies of the entity system.
// ---------------------------------------------------------------------------------------- //
// This is also a good place to test new code since it's run right when the engine
// starts up. It can also be put into standalone apps easily.
// ---------------------------------------------------------------------------------------- //
// Things it tests:
// - Data transmission integrity.
// - Delta calculation.
// - Strings, floats, vectors, recursive datatables, and ints.
// - Fixed-length arrays.
// - Variable-length arrays.
// - Exclude props.
// - Recursive datatables.
// - Datatable proxies returning false.
// - CUtlVectors of regular types (like floats) and data tables.
// ---------------------------------------------------------------------------------------- //
// Things it does not test:
// - Quantization.
// - Clamping.
// - The entity system's usage of data tables.
// - Stress testing - too many properties, maxing out delta bits.
// - Built-in and custom client and server proxies.
// ---------------------------------------------------------------------------------------- //
// At a high level, the test is setup as such:
// - Server structure and datatable.
// - Client structure and datatable.
// - A function table with a function to modify and compare each element.
// - A function that initializes the server structure and tries random changes to it and
// verifies that the client receives the deltas and changes correctly.
// ---------------------------------------------------------------------------------------- //
// Eventually it would be nice to stress-test the entities with tests for:
// - Misordered proxy callbacks and missing data.
