Replacing Wallbuys in Existing Stock Maps in Scripting

Created on: March 12, 2023, 06:01:42 pm

Just thinking of using TheSkyeLord's BO ports, seem to work for the mystery box...
Had a look around at some old WaW mods for reference, and initially thought to copy over _zm_weapons.gsc and edit init_weapon_upgrade like so:

Code Snippet

Plaintext

function init_weapon_upgrade()
{
    init_spawnable_weapon_upgrade();
    
    weapon_spawns = ;
    weapon_spawns = GetEntArray( "weapon_upgrade", "targetname" ); 

    for ( i = 0; i < weapon_spawns.size; i++ )
    {
        mapname = GetCurrentMap(); //no, this is Lua not GSC
        switch(mapname)
        {
        //Kino Der Toten
        case "zm_theater":
            switch ( weapon_spawns[i].zombie_weapon_upgrade )
            {
            case "ar_marksman": //Sheiva
                weapon_spawns[i].zombie_weapon_upgrade = "t5_olympia";
                break;
            case "pistol_burst": //RK5
                weapon_spawns[i].zombie_weapon_upgrade = "t5_m14";
                break;
            case "smg_burst": //Pharo
                weapon_spawns[i].zombie_weapon_upgrade = "t5_pm63";
                break;
            //Remove Vesper
            case "shotgun_precision": //Argus
                weapon_spawns[i].zombie_weapon_upgrade = "t5_stakeout";
                break;
            case "smg_waw_mp40":
                weapon_spawns[i].zombie_weapon_upgrade = "t5_mp40";
                break;
            case "ar_standard": //KN-44
                weapon_spawns[i].zombie_weapon_upgrade = "t5_mp5k";
                break;
            case "ar_accurate": //ICR-1
                weapon_spawns[i].zombie_weapon_upgrade = "t5_m16a1";
                break;
            case "pistol_fullauto": //L-CAR 9
                weapon_spawns[i].zombie_weapon_upgrade = "t5_mpl";
                break;
            case "smg_versatile": //VMP
                weapon_spawns[i].zombie_weapon_upgrade = "t5_ak74u";
                break;*/
            /*case "bowie_knife": //handle these later
                weapon_spawns[i].targetname = "bowie_upgrade";
                break;
            case "bouncingbetty":
                weapon_spawns[i].zombie_weapon_upgrade = "bouncingbetty";
                break;
            case "frag_grenade":
                weapon_spawns[i].zombie_weapon_upgrade = "stielhandgranate";
                break;*/
            }
            break;
       
           ...
       
       }
            
       weapon_spawns[i].weapon = GetWeapon( weapon_spawns[i].zombie_weapon_upgrade )

Spoiler: click to show...

maybe figure out the map-specific part of the code later

Then thought to move the code after that last line and test the switch statement for weapon_spawns[ i ].weapon instead with appropriate GetWeapon calls.
Tried doing similar in reset_wallbuys but I don't think that was meant to work either.

Maybe I'll get help starting on the chalk outlines as well while I'm at it...

                    }
                }
                break;
            }
        }
    }
}

Very lucky the wallbuys are passed through to the script in the same order every time so we can replace the Ascension starting room RK5 with the Olympia and the other RK5 with the MP5K.

spawn_loc.origin + VectorScale((0, -1, 0), 1) allows adjusting the position of the chalk drawing so it matches up with the pop-up model

The chalk drawings themselves are spawned in with models (basically just a flat plane with UV set up to point to the relevant material) which I was lazy and unknowledgeable enough to just rip using Greyhound from https://steamcommunity.com/sharedfiles/filedetails/?id=2049603169 and re-export with Birdman's XModel Tools after conversion to .obj

The original chalk drawing textures are replaced with blank transparent .tiff images in texture_assets\t7_materials_zombie, easy enough to import in zm_mod.zone with an image,i_t7_zm_chalk_buy_arak_c etc. entry
Some materials had to be added using APE because they aren't accessible by default (Argus, Pharo (i_t7_zm_chalk_buy_pharaoh_c), MP40, HVK-30).

    //same as in zm_swap_weapons.gsc

Edit: To make it clearer, the zm_swap_weapons::swap_wall_weapon() function call should be put before the spawn_list/spawnable_weapon_spawns array set-up in the function. If you can't see those lines of code underneath where you've pasted, you're putting it in the wrong place.

    spawnable_weapon_spawns = ArrayCombine( spawnable_weapon_spawns, struct::get_array( "buildable_wallbuy", "targetname" ), true, false );
    
    ...
    
}

    zm_swap_weapons::swap_wall_weapon();

    //pre-existing code, only copy above
    spawn_list = ;
    spawnable_weapon_spawns = struct::get_array( "weapon_upgrade", "targetname" );
    spawnable_weapon_spawns = ArrayCombine( spawnable_weapon_spawns, struct::get_array( "bowie_upgrade", "targetname" ), true, false );
    spawnable_weapon_spawns = ArrayCombine( spawnable_weapon_spawns, struct::get_array( "sickle_upgrade", "targetname" ), true, false );
    spawnable_weapon_spawns = ArrayCombine( spawnable_weapon_spawns, struct::get_array( "tazer_upgrade", "targetname" ), true, false );
    spawnable_weapon_spawns = ArrayCombine( spawnable_weapon_spawns, struct::get_array( "buildable_wallbuy", "targetname" ), true, false );
    
    ...
    
}

Now to figure out how to change the position of the weapon model pop-up...

Trying to implement JBird632's Custom Claymores to replace Trip Mines needs some specific ordering: first add a new wallbuy .gsc-side while you still have location info then delete the previous ones both server- and client-side.

Code Snippet

cpp

//_zm_weapons.gsc

function init_spawnable_weapon_upgrade()
{
    zm_swap_weapons::swap_claymores();
    zm_swap_weapons::swap_wall_weapon();

Evidently trigger_radius_use did not work on its own so time to use unitriggers and then execute zm_claymore::init at the end of the function...

Code Snippet

cpp

//zm_swap_weapons.gsc

#using scripts\zm\zm_claymore;
#using scripts\zm\_zm_unitrigger;

...

function swap_claymores()
{
    foreach(ent in struct::get_array("claymore_purchase", "targetname"))
    {
        VAL = ent.zombie_weapon_upgrade;
        if(!isdefined(VAL))
        {
            continue;
        }
        spawn_loc = struct::get(ent.target, "targetname");
        claymore = Spawn("trigger_radius_use", spawn_loc.origin, 0, 84, 72);
        claymore.targetname = "claymore_trigger";
        claymore zm_unitrigger::create_unitrigger( "Hold ^3&&1^7 to buy Claymores [Cost: 1000]" , 20, &visibility_and_update_prompt);
        if(isdefined(claymore))
            claymore.spawnmodel = util::spawn_model("wallbuy_claymore", spawn_loc.origin + VectorScale((0, -0.5, 0), 1), spawn_loc.angles);
    }
    thread zm_claymore::init();
}

function visibility_and_update_prompt( player )
{
    if(isdefined(self.hint_string))
    {
        self SetHintString( self.hint_string );
    }
    return true;
}

change the waittill from trigger to trigger_activated:

Code Snippet

cpp

//zm_claymore.gsc

function purchaseClaymores()
{
    trigger = GetEnt("claymore_trigger", "targetname");
    trigger.zombie_cost = 1000;    
    trigger SetHintString( "Hold ^3&&1^7 to buy Claymores [Cost: 1000]" );    
    trigger SetCursorHint( "HINT_NOICON" );
    trigger.claymore_triggered = false;
    
    thread give_claymores_after_rounds();

    while(1)
    {
        trigger waittill("trigger_activated", player);
    
        ...
        
    }
    
    ...
    
}

(apparently also needed to change a PlaySoundAtPosition to use zmb_cha_ching instead of purchase)

and delete the Trip Mine structs:

Code Snippet

cpp

//zm_swap_weapons.gsc, zm_swap_weapons.csc

function swap_wall_weapon()
{

    ...

    foreach(ent in struct::get_array("claymore_purchase", "targetname"))
    {
        VAL = ent.zombie_weapon_upgrade;
        if(!isdefined(VAL))
        {
            continue;
        }
        ent struct::delete();
    }
}

And I suppose to find out how to make the claymore weaponmodel pop out of the wallbuy...?

Either relative movement:

Code Snippet

cpp

case "pistol_burst": //RK5
{
    ent.zombie_weapon_upgrade = "t5_olympia";
    ent.origin += (0, 10, 0);
    spawn_loc = struct::get(ent.target, "targetname");
    spawn_loc.origin += (0, 10, 0);
    break;
}

or repositioning altogether

Code Snippet

cpp

case "smg_fastfire": //Vesper
{
    ent.zombie_weapon_upgrade = "t5_aug";
    ent.origin = (3, 926, -30);
    ent.angles = (0, 180, 0);
    spawn_loc = struct::get(ent.target, "targetname");
    spawn_loc.origin = (3, 926, -30);
    spawn_loc.angles = (0, 180, 0);
    break;
}

Hey, so im trying to follow your findings and I have a question...do I have to edit the _zm_weapons.gsc file and create a zm_swap_weapons.gsc and .csc?

To change the train wallbuy on Shadows of Evil, use this:

Code Snippet

gamescript

foreach(ent in GetEntArray("train_buyable_weapon", "script_noteworthy"))
    ent.zombie_weapon_upgrade = "s2_sten";

I've yet to figure out how to change the spawned weapon model, currently returning an error indicating that the .model property of the usual ent.target entity is read-only.
