Call of Duty 5: Minefields

This tutorial will explain how to create/add Minefields to your maps.

Simple Minefield

In Radiant

• Choose the Trigger texture,
• Drag it where you want a minefield..
• Rightclick > Trigger > Multiple

• Bring up console (press N)

Give it these values:

Key: targetname
Value: minefield

GSC Scripts

Make sure the following is present in your maps/mp/mp_mapname.gsc

maps\mp\_load::main();

SoundAlias

• The two sound used by the stock script are missing from Soundaliases files and even the WAV files are missing, get them here:

DOWNLOAD MISSING MINEFIELD ASSETS

• In this Archive you will find the Soundalias required, distance and volume can be adjusted before compile to your liking;
• Simply unpack the archive in your CODWaW Root folder to add the missing assets;

Zone Source

Add the following to your zone_source/mp_mapname.csv before compiling:

fx,explosions/grenadeExp_dirt
sound,mines,mp_yourmap,all_mp

You're done!

Alternate Idea

This great idea comes from HyBr!d and it is to replace the actual mine by a Sniper shoot at the player when he walk in the Trigger. Sound are replace:

• Bullets whizzing by instead of the 'click'
• Sniper rifle shot as the explosion sound

The GSC Code for it:

waterfields()
{
    waterfields = getentarray("waterfield", "targetname");
    if (waterfields.size > 0)
    {
        level._effect["water_explosion"] = loadfx ("impacts/fx_water_hit_tracer_nite.efx");
    }
    
    for(i = 0; i < waterfields.size; i++)
    {
        waterfields[i] thread waterfield_think();
    }    
}

waterfield_think()
{
    while (1)
    {
        self waittill ("trigger",other);
        
        if(isPlayer(other))
            other thread waterfield_kill(self);
    }
}

waterfield_kill(trigger)
{
    if(isDefined(self.waterfield))
        return;
        
    self.waterfield = true;
    self playsound ("shot_flyby");

    wait(.5);
    wait(randomFloat(.5));

    if(isdefined(self) && self istouching(trigger))
    {
        origin = self getorigin();
        range = 50;
        maxdamage = 2000;
        mindamage = 50;

        self playsound("waterfield_shot");
        playfx("water_explosion", origin);
        radiusDamage(origin, range, maxdamage, mindamage);
    }
    
    self.waterfield = undefined;
}

This code must be paste into the Stock file /raw/maps/mp/_minefields.gsc (Backup first!) and of course you must add this line to your Zone file:

rawfile,maps/mp/_minefields.gsc

• Soundalias to go with the new code:

name,sequence,file,platform,vol_min,vol_max,pitch_min,pitch_max,dist_min,dist_max,dist_reverb_max,limit_count,limit_type,entity_limit_count,entity_limit_type,bus,priority,spatialized,type,probability,loop,masterslave,loadspec,reverb_falloff_curve,subtitle,compression,randomize_type,secondaryaliasname,chainaliasname,volumefalloffcurve,startdelay,speakermap,reverb_send,lfe percentage,center percentage,platform,envelop_min,envelop_max,envelop percentage,move_type,move_time,occlusion_level,min_priority,max_priority,min_priority_threshold,max_priority_threshold

• Again you must add a line the Zone File to add this soundalias (called waterfields.csv in this example):

sound,waterfields,mp_yourmap,all_mp
