Call of Duty 5: SP Tutorial Spiderholes

Spiderholes

Spiderholes can be set up a few different ways, but in this example map we’ll focus on the ones that are set up entirely in Radiant. You'll need a few components, so I'll lay them out for you in the steps below. There are several spiderhole "behaviors" that you can use:

• jump_out – This causes the enemy to jump out of the spiderhole and either charge at the player or go to his targeted cover node, (more on this later).
• stumble_out – Just like jump_out but the enemy will stumble a bit, giving the player an opportunity to take him out easier.
• grenade_toss – The enemy will peek out of the hole, toss a grenade, and then randomly choose between jump_out and stumble_out behavior.
• gun_spray – The enemy will blindly spray his gun in an effort to surprise the player, after which he will choose between jump_out and stumble_out behavior.
• jump_attack – The enemy will just toss open the cover and stay inside the spiderhole firing his weapon. He will never leave the spiderhole.

Setting Up a Spiderhole:

1. Place the spiderhole base model into your map as a misc_model:

• Model: static_okinawa_spiderhole_base

2. Place the spiderhole lid into the map as a script_model and give it the exact same origin & angles as the spiderhole base placed in step 1.

• Model: okinawa_spiderhole_lid or okinawa_spiderhole_lid_tall

3. Select the spiderhole lid and enter the following key/value pair:

Key: script_noteworthy

Value: spiderhole_lid

4. Place a script_struct into the map and give it the exact same origin & angles as the spiderhole lid and base. By now, it should look something like the picture below:

5. Place an appropriate Japanese actor into the map, (i.e. actor_axis_jap_guard_type99riflebayonet). Make sure to check the spawner checkbox. Below are the values you can use to set up the spawner correctly for spiderhole use:

Key: script_spiderhole

Desc: This tells the spawner system that this guy should use spiderhole behavior.

Value: 1

Key: script_spiderhole_anim

Desc: This tells the spiderhole scripts which behavior to use.

Value The possible values are listed below:

• jump_out
• grenade_toss
• gun_spray
• stumble_out
• jump_attack

Key: script_spiderhole_charge

Desc: Determines if the guy should attempt to Banzai charge the nearest player, (not valid for jump_attack). The spawner can optionally have cover nodes targeted, so if he does not Banzai attack, he can jump out and run to his targeted node.

Value: Integer from 0-100. (A value of 0 and the guy will not charge. A value of 100 will make hm charge 100% of the time). Values less than 100 should have the spawner targeting a node so he doesn't just jump out and stand there.

Key: script_delay_min

Desc: Minimum amount of time to wait before spawning.

Value: float value

Key: script_delay_max

Desc: Maximum amount of time to wait before spawning

Value: float value

6. Now we need to link everything together:

a. Select the spawner, then select the spiderhole lid and press W to target the spawner to the lid.

b. Select the spawner, then select the script_struct and press W to target the spawner to the struct.

c. Select the spawner and optionally target a node you want the guy to run to once he gets out of the spiderhole.

7. Place a trigger in the map that you want the spiderholes to be spawned from. Select the trigger and select the spawner and press W to target the spawner from the trigger. Make sure to check the "TRIGGER_SPAWN" checkbox for the trigger.

8. That's it for the Radiant setup. The final setup should look soemthing like this pic below: (trigger targets the spawner, spawner targets both the lid & the script_struct).

9. The last step is to make sure you've got all the required elements in your level zone file,(.csv), and your level script file, (.gsc).

• Put the following lines into the .csv file. The include files and _spiderhole_util.gsc are provided for you in the example_ambush.zip archive .

• rawfile,maps/_spiderhole_util.gsc
• include,spiderholes
• include,bayonet
• include,common_banzai
• xmodel,viewmodel_usa_marine_arms
• xmodel,viewmodel_usa_marine_player

• Add the following lines of script to your level script BEFORE the call to _load::main()

• maps\_spiderhole_util::init_spiderholes();
• maps\_banzai::init();

That's it! Now you should have everything you need to get the spiderholes working.
