Gamedata

MatchZy resolves a few native game functions by name from CounterStrikeSharp's gamedata. CounterStrikeSharp merges every *.json in its gamedata/ directory, so the shipped gamedata/matchzy.json provides them without editing the core gamedata.json. This is what lets the plugin run on stock CounterStrikeSharp.

Key	Type	Used by
CSmokeGrenadeProjectile_Create	signature	Practice grenade rethrow (.rt, .last, .back)
CHEGrenadeProjectile_Create	signature	Practice grenade rethrow
CMolotovProjectile_Create	signature	Practice grenade rethrow (molotov and incendiary)
CDecoyProjectile_Create	signature	Practice grenade rethrow
CCSGameRules_PostCleanUp	signature	.breakrestore (respawn breakable props)
CBasePlayerController_HandleCommand_JoinTeam	signature	.t / .ct from spectator in practice (the older name CCSPlayerController_HandleCommandJoinTeam is also accepted)
CCSPlayer_WeaponServices_SelectItem	vtable offset	Putting a restored grenade or weapon in hand (.last, .back, .ln)

When a key goes stale

Valve updates can move these functions. A stale or missing key degrades gracefully:

• Grenade rethrows fall back to a managed spawn path and log a warning naming the missing key.
• .breakrestore, the spectator team switch and the weapon selection turn into no-ops (the team switch falls back to the old behavior plus a team-menu hint).
• The log shows lines such as CCSPlayer_WeaponServices_SelectItem offset missing.

The fix is a fresh matchzy.json for the new CS2 build (Linux libserver.so, Windows server.dll). Update MatchZy, or regenerate the signatures yourself and replace the file.
