Call of Duty 5: Exploding barrels

By Daevius

Abstract

We select a model (barrel), make it a script_model, assign it targetname = explodable_barrel and script_noteworthy = explodable_barrel. To the .gsc file we add:

maps\mp\_interactive_objects::init();

And to the .csv file we add:

rawfile,maps/mp/_interactive_objects.gsc

fx,destructibles/fx_barrelexp_mp
fx,destructibles/fx_barrel_ignite
fx,destructibles/fx_barrel_fire_top

xmodel,exploding_barrel_test_d

Preparing your map

• We first select a barrel prefab, grab one HERE
• Once you have the file, unzip in your COD folder
• Back in Radiant, Right click in the 2D grid and click misc -> prefab. Now browse to your [root]/map_source/_prefabs/interactable_objects/ directory, select the file called explodable_barrel.map, click Open and the prefab will appear in the map. Move it around till it's settled.
  

Calling the script

Now, in our .gsc file, located in [root]/raw/maps/mp/mp_[mapname].gsc, we need to add the following line (you can edit .gsc files using notepad):

maps\mp\_interactive_objects::init();

So, your .gsc file might become:

main()
{
	maps\mp\_interactive_objects::init(); // added line
	maps\mp\_load::main();

	// If the team nationalites change in this file,
	// you must update the team nationality in the level's csc file as well!
	game["allies"] = "marines";
	game["axis"] = "japanese";
	game["attackers"] = "allies";
	game["defenders"] = "axis";
	game["allies_soldiertype"] = "pacific";
	game["axis_soldiertype"] = "pacific";

	setdvar( "r_specularcolorscale", "1" );

	setdvar("compassmaxrange","2100");
	
	// enable new spawning system
	maps\mp\gametypes\_spawning::level_use_unified_spawning(true);
}

Adding it to the FastFile

To use the script we call in out .gsc file, we need to include it into our .ff file. Go to [root]/zone_source/mp_[mapname].csv and open it using notepad. Add the following lines to it (on it's own row!):

rawfile,maps/mp/_interactive_objects.gsc

fx,destructibles/fx_barrelexp_mp
fx,destructibles/fx_barrel_ignite
fx,destructibles/fx_barrel_fire_top

xmodel,exploding_barrel_test_d

A typical .csv file might now look like this (where mp_test is the map name):

ignore,code_post_gfx_mp
ignore,localized_code_post_gfx_mp
ignore,common_mp
ignore,localized_common_mp

col_map_mp,maps/mp/mp_test.d3dbsp

rawfile,maps/mp/mp_test.gsc
rawfile,vision/mp_test.vision
rawfile,maps/mp/_interactive_objects.gsc

fx,destructibles/fx_barrelexp_mp
fx,destructibles/fx_barrel_ignite
fx,destructibles/fx_barrel_fire_top

xmodel,skybox_mak1
xmodel,exploding_barrel_test_d
