Announcing Art of Defence (AOD) maps

The past week we have been working hard to get this mod off the ground, you can find it in the steam workshop here:
Official AOD mod + maps collection

Basically it’s a game mode where you alone or with your friends have to defend against several waves of AI units. They spawn at one end of the map and follow a path to the other end. When they reach that end, you lose. When you kill all the waves, your team wins. Easy.

The waves will vary per map and consist of infantry and vehicles. Setting the opponent AI difficulty will change the difficulty of the map:

Easy – AI units won’t attack while on route
Normal – AI units will attack while on route
Hard – AI units won’t be suppressed and have veterancy 1
Hardest – AI unit’s very strong, fast and have veterancy 3

Besides that there are several events that can be triggered between waves, like bombing of units and defences.

Currently we are adding this game mode to already existing CoH2 maps, like “Langreskaya” and “Rails and Metal”, but we aim towards providing a framework to the community so more people can make awesome AOD maps. This framework is super easy to understand, we will provide some documentation when we release it.

You will have to install the “Art of Defence” victory condition mod, this holds all the scripts for the game mode. Besides that the individual levels only hold the parameters of the map, like units to spawn, events to trigger, etc. When you want to play, you’ll have to choose the AOD mod as victory condition mod.

Here are two short videos showcasing our mod:

Hope you like it, we’ll keep you updated!

To make your own AOD level, you need the following stuff in your level:

Markers

Code

For each path:
Spawn marker			-- Spawn location
Spawn direction marker		-- Spawn direction 
Path or target marker		-- AI will either follow a path or move to the given target

For each sneak attack:
Spawn marker			-- Spawn location
Spawn direction marker		-- Spawn direction
Entry point marker		-- AI will move towards this marker when spawned

For each failure position
Failure marker			-- Players will fail if AI reaches this point (20m range)

Also create a marker that has all enemy bases within its range
Enemy base marker		-- All buildings will be destroyed on level start

Groups

Code

Path sector entity group	-- Group that holds all sectors that contain the route for the AI

Level code

Code

Nice idea guys. It's like a tower defence almost!

Posts: 12

Sounds like fun! I'll try it out this evening.

Would you consider implementing a setting allowing for an infinite number of waves, with each wave getting gradually harder and harder (and maybe a way to keep track of how many waves you have cleared)?

Sounds like fun! I'll try it out this evening.

Would you consider implementing a setting allowing for an infinite number of waves, with each wave getting gradually harder and harder (and maybe a way to keep track of how many waves you have cleared)?

The waves are set manually by the map maker.

If you copy the "code" in one of littlebit's posts, and put it in a txt file in notepad ++ (set language to LUA), you will notice that each wave can be set with different Parameters. So the amount of waves is always finite, but the mapmaker can make each wave stronger. I will explain this in a video tutorial and a guide soon.

Code

		[2] = 	{
					["units"] = {
							[1] = {
									["type"] = "combat_engineer_squad_mp",
									["amount"] = 15,
									["interval"] = 3,
									["spawns"] = {2},
									["slots"] = {"dp-28_light_machine_gun_package_moving_mp", "dp-28_light_machine_gun_package_moving_mp"},
									["upgrades"] = {"engineer_minesweeper"}
								},
							[2] = {
									["type"] = "rear_echelon_squad_mp",
									["amount"] = 15,
									["interval"] = 3,
									["spawns"] = {1},
									["slots"] = {"paratrooper_thompson_sub_machine_gun_upgrade_mp"},
									["upgrades"] = {"minesweeper_upgrade_mp"}
								}
						},
					["wait_until_everybody_dead"] = true,
					["delay_after_wave"] = 30.0,
					["event_when_starting"] = {},
					["hurt_moving_friendly_squads_on_route"] = false,
					["hurt_friendly_squads_on_route"] = false,
					["bomb_friendly_squads_on_route"] = false,
					["bomb_friendly_entities_on_route"] = false,
					["message_when_starting"] = {
							["title"] = "Secure the area and destroy the capitacommunilist army!",

							["desc2"] = "",
							["fadein"] = 1.0,

					}
				},

I assume you mean something like a survival mode. This can easily be done by randomizing every wave and making it bigger/stronger, but with a random setup it's hard to maintain the same difficulty.

We'll stick to pre-setup waves for now, but maybe in the future I could add some code to loop them around or so.

Thanks for the suggestion though!

We will be guests at Stormless his stream tomorrow around 4 pm CET, we'll play our new 4 player AOD map and explain what our future plans are for the mod. Tune in and ask us questions!

Thanks to littlebitpwnsu for making this mod.

It was very fun to play with a friend. (We are still lossing versus Hard IA)

thanks! We just received news that two guys managed Extreme on Langres.
How?
By camping like shit lol. At gun emplacements spam and command tanks.

I tried to make a AOD version of my map ( http://www.coh2.org/topic/29188/4-6-enix--8-enix ) , but when I tried to play the units and everything did not move.

I simply placed in the map this markers:

AOD_spawn_1
AOD_spawn_direction_1
AOD_dest_fail
The enemy base marker to destroy the enemy buildings. AOD_enemy_base
and made an invisible point to paint the terrain where units will move, and created a group entity wich its called: AOD_path_sectors.

Did I forgot about any marker? I'm assuming the problem is that the map is trying to load a marker which is not in the map. Maybe AOD_path_1? hat is that exactly?

Edit:
Nevermind, its waypoint placement, not markers. I think the problem it's solved now.

Edit2:

not working, it says that you need an AOD map to play this mod, when it is supposed to be an AOD map. At this moment I really don't know what else to do. The enemy bases have to be placed in a specific place? I noticed you placed them outside of the map, but I can't do that in the editor, map just won't save.

Hey man, very nice to see that you are creating your own map!

Did you properly copy over the script to your own map? Add me on steam if you want better support, you can find my profile on the mod description page.

add us to steam if you'd like. The tutorial is almost done. We can already send it to you if you'd like.

thank you all for your help, I got it working, here is the beta release:
http://steamcommunity.com/sharedfiles/filedetails/?id=370985236

It is for 4 players, and has basic markers for bombing runs, artillery, paratroopers and sneak spawn points. It has 12 waves, 4 enemy spawn points and 1 end. Waves are pretty much a copy of the ones seen in your 2 player AOD modified map, and as this is for 4 players maybe I should add more enemies, but first I should test it with 4 human players on hard, and see if I need to increase the difficulty for it or not.

Feel free to post any suggestions for it
