Notes on how devving on playtime works

Foreword #

The codebase does not use any C++ default namespaces by standard - this was introduced in C++ 1995, which was before the time where HL1 had started development.
The only C++ feature used within the code is the class type, but everything in the game is registered to the singular global namespace.
This is done to improve the performance & loading of the game.

Gotchas #

There’s a few catches and exceptions we encountered trying to make this game work, so to save you a lot of hassle I went through them all and listed all the issues & their fixes accordingly :drill:

Player #

All player related functions can be found in the player.cpp file.
The HEV sound on death has been removed.,

Damage #

The player’s damage is defined in the player.cpp file. At base, it is set to 100.

ConVars #

In GameDLL.cpp, this could be where the literal game starts, but we just don’t know.
When you call the RegisterConVar function from that file, you can successfully add a ConVar into the game.

Debug #

When debug is set with the DEBUG macro, special game rules are applied within the game.
This can lead to a few gotchas, i.e:

• If the game is in DEBUG mode, the player will automatically be given a suit.

Colours #

Colors are set like this

if (HL_RGB)
{
    (*r == 0) ? 124 : *r;
    (*g == 0) ? 84 : *g;
    (*b == 0) ? 12 : *b;
}
