Add Destructibles To Your Map

From CustomCoD Wiki

All the builder has to do for this to work in their level is right-click in the 2D window, choose Destructible, then choose the MP destructible they want to use.

If they don’t use MP destructible assets, the script will assert and tell them to replace the SP asset with an MP asset.

The following is a list of all usable destructibles in MP:

Audi_mp

Beetle_mp

Bench/ recihstag_mp

Berlin/potted/plant01_mp

Berlin/statue/inarch_mp

Berlin/statue/reich01_mp

Bmwmotorcyle_mp

Horch1a_mp

Mercedesw136_mp

Opel/blitz_mp

Pelilu/generator/mobile_mp

Type94truck_mp

Type95scoutcar_mp

For explodable barrels:

Misc/prefab/scripter/explodable_barrel.map

Misc/prefab/scripter/explodable_barrel_requiresplayer.map

Misc/prefab/scripter/ explodable_barrel_selfisattacker.map

For explodable ammo crates:

Misc/prefab/scripter/ flammable_crate.map

Misc/prefab/scripter/ flammable_crate_requiresplayer.map

Misc/prefab/scripter/ flammable_crate_selfisattacker.map

The three exploadable barrel types and ammo crates types are essentially all the same.

But you can use either of the three for the same effect.

Please be sure you use ONLY MP destructible assets in your levels.

You can use SP barrels and ammo crates with no problem.

There are currently no dedicated MP explodable barrels and crates.
