Notes

q_shared.c

STAT_TEAM_WEAPON is a "slot" (24) reserved in the client data structures to hold a string that contains the team weapon

p_hud.c

DeathmatchScoreboardMessage was originally changed by a QDevels tutorial for a new format scoreboard that shows more players. This was then further amended by the teamplay enhancements tutorial (15) to show team scores and what teams players are on:
- and both teams have been updated to show what weapon their players use
update_hud_rockets has been amended to store the name of the team's wepaons prior to being displayed on the hud, as specified in g_spawn.c, in the slot in the player's ps.stats structure reserved by STAT_TEAM_WEAPON.
init_hud_rocket_strings, at the start of a game, pre-defines all the constant strings to be displayed on the player's hud:
- the strings for the team weapons are defined
- CS_TR_STRINGS, created in reserves a set of "slots" in the client structure for constant strings we are adding

g_spawn.c

dm_statusbar is the string used by Quake engine to display a player's hud in deathmatch games. It was amended in tutorial 16, display team info, to display the name of the player's team:
- start position of team name moved to left to make room for weapon name
- and weapon name insert right after team name
- "stat_string 24" correpsonds to the value in ps.stats reserved by STAT_TEAM_WEAPON.

Exercises

if in tutorial 18 you have added more team weapons, this tutorial will need to be modified to add the weapon names in here
