开始修改
In this section we will be creating our custom gamemode. this is more complicated than creating setting mods however also allows for more freedom at the cost of being required clientside as well
the gamemode itself
We are going to make a simplified version of the "infection" gamemode.
Lets break it down into steps before we make the gamemode itself
Set the gamerules such as player count, team layout and score system
force all players on to 1 team at the start of the game
randomly select 1 player as being the zombie
equip this player with the correct weapons
modify their health
provide them a speedboost
have players become zombies on death
have players joining mid way become zombies
end the game when the last player dies.
Now lets breakdown the callbacks we will need
for steps 2 and 5 we will need AddCallback_OnClientConnected( PlayerJoined )
to trigger on join
for step 3 we will need to AddCallback_GameStateEnter( eGameState.Playing, StartGame )
for step 4 we need AddCallback_OnPlayerRespawned( RespawnInfected )
and finally to decide the winner we need a new function we havent seen yet. SetTimeoutWinnerDecisionFunc( DecideWinners )
this function is used to decide the winner when the game runs out of time by calling a function.
now that we know our steps its time to start our initialisation function
Initialisation function
first, lets declare our game settings
global function SimpleInfection_init
void function SimpleInfection_init(){
SetSpawnpoint GamemodeOverrde( FFA )// This line makes the player spawn locations like those from ffa
SetLoadoutGracePeriodEnabled( false )// we dont want the zombies to be able to change loadouts and grab their guns, so lets disable that
SetWeaponDropsEnabled(false )// we dont want zombies grabbing the weapons for dead survivors, so lets disable that.
Riff_ForceTitanAvailability( eTitanAvailability.Never )// we dont want zombies to have titans either, so lets disable that
Riff_ForceBoostAvailability( eBoostAvailability.Disabled )// we also dont want the zombies grabbing smart pistols and turrets, so lets disable that
ClassMP_ForceDisableEpilogue( true )// As the goal is surviving till the timer runs out, we dont need the evac dropship
Next lets setup our callbacks:
AddCallback_OnClientConnected( PlayerJoined )
AddCallback_GameStateEnter( eGameState.Playing, StartGame )
AddCallback_OnPlayerRespawned( RespawnInfected )
SetTimeoutWinnerDecisionFunc( DecideWinners )
}
great, now we have our gamemodes initialisation function we need a way for our callbacks to know some things, such as whether the game has started or not, you will see why later
struct {
bool HasStarted = false
} file
Structs like this allow us to store Values that can be accessed elsewhere in the script, without having to pass them as arguments in all our functions. we place them in a struct instead of just defining them as a global variable cannot be modified by a function in squirrel, wheras a struct like this one can.
to access a variable in a struct you must format it using the name of the stuct followed by the variable itself, in this case file.HasStarted
Main functions
Now it time to start writing our callbacks
void function PlayerJoined(entity player){
if (file.HasStarted){
InfectPlayer( player, player)
RespawnInfected( player )
}
else{
SetTeam( player, 0)
}
}
This manages what happens when a player joins, but it calls a function we dont have yet InfectPlayer
so lets define it now
void function InfectPlayer(entity player, entity attacker){
SetTeam( player, 1)
if ((GetPlayerArrayOfteam(0).len()) == 0){
SetRespawnsEnabled(false)
SetKillcamsEnabled(false)
SetWinner( 1 )
}
}
This function simply changes the players team, then checks if there are any survivors left, and if not sets the zombies as the winners.
Now for the script that chooses the first zombie, in order to allow more time for players to join lets put a delay on it using a thread
void function StartGame(){
firstinfected = GetPlayerArray()[RandomInt(GetPlayerArray().len())]
InfectPlayer( firstinfected, firstinfected)
file.HasStarted = true
}
This function changes the file.HasStarted value to true and randomly selects a player from the player array as a target for the infectplayer function.
Next lets create the function that provides the zombies the correct equipment
void function RespawnInfected( entity player ){
if (player.GetTeam() != 1){//this makes sure players dont accidentally get given zombie weapons when first spawning as a survivor
return
}
//lets give them stim, followed by increased air accel
StimPlayer( player, 9999)
player.kv.airAcceleration = 2000
//lets give them less health than normal
payer.SetMaxHealth(20)
//lets set their loadout
foreach ( entity weapon in player.GetMainWeapons() )
player.TakeWeaponNow( weapon.GetWeaponClassName() )
foreach ( entity weapon in player.GetOffhandWeapons() )
player.TakeWeaponNow( weapon.GetWeaponClassName() )
player.GiveOffhandWeapon( "melee_pilot_emptyhanded", OFFHAND_MELEE )
//unfortunately the game requires that you have a weapon of some kind in order to use secondaries, so lets give zombies an MGL
player.GiveWeapon( "mp_weapon_mgl" )
}
Finally lets define what occurs when the match ends
void function DecideWinners(){
SetRespawnsEnabled( false )
SetKillcamsEnabled( false )
return 0
}
Now we can save this file as _gamemode_simpleinf.gnut and place it in "ourmodsname"/mod/scripts/vscripts/gamemodes
