env_mortar_controller

env_mortar_controller is a point entity available in Black Mesa. This is an airstrike map that allows you to mark and launch bombs at a specified point. For full functionality, this entity must be used in combination with env_mortar_launcher, point_camera and info_camera_link. In the original game it was used once in bm_c2a5i. Most inputs and outputs are same as CBaseAnimating.

Represented by class CEnvMortarController.

Bug:In current versions of the game, this entity have no fire delay (the fire button lock doesn't happen). If player will spam the button - this will create a lot of bombs which will cause huge fps drop (due to explosions) and then may cause the game to crash (not in ).

Workaround:See workaround below.

Bug:This entity doesn't work properly in multiplayer, only 1 player will be able to shoot, the crosshair will not work for others.

Mortar Launcher (mortarlauncher) <targetname>

env_mortar_launcher to use.

Inputs

attachscreen <void> !FGD

Fires on entity spawn to attach screen.

Attaching screen

First, place point_camera at required position, set orientation and give a name. This entity will display area in airstrike map. You also need to change value for Render Target, set _rt_Satellite value.

• 

  Example.

Now we need info_camera_link. In Entity Whose Material Uses _rt_camera you need to add name of env_mortar_controller, in Camera Name add name of point_camera you placed earlier.

• 

  Example.

Now compile your map and check the result. You now have functional screen. Don't forget to specify env_mortar_launcher name in Mortar Launcher property.

Fixing mortar spam

env_mortar_launcher can dynamically change values in properties with AddOutput, we'll use this feature to fire 0 shells when fired once. Unfortunately, env_mortar_launcher and env_mortar_controller don't have any outputs that fires when shell is launched, we need to use triggers instead.

Create a trigger_weaponfire in the form of an empty box inside. There should be a free space of 30 hammer units inside (x, y, z), env_mortar_launcher should be placed in the center.

• 

  Example.

Now create another trigger_weaponfire that is 12 hammer units in size on all axes. This trigger should be in env_mortar_launcher center. Give a name for this trigger (shellkiller for example) and for Start Disabled? property set value Yes.

• 

  Example.

We need to add outputs now, for the second trigger (shellkiller) make the following output:

		My output	Target entity	Target input	Parameter	Delay	Only once	Comments
		OnStartTouch	!activator	Kill		0.00	No

For the first trigger, make the following outputs:

		My output	Target entity	Target input	Parameter	Delay	Only once	Comments
		OnStartTouch	shellkiller	Enable		0.00	No
		OnStartTouch	mortar_launcher	AddOutput	fireshellscount 0	0.00	No	mortar_launcher is the name of env_mortar_launcher.
		OnStartTouch	shellkiller	Disable		2.00	No
		OnStartTouch	mortar_launcher	AddOutput	fireshellscount 1	2.00	No

Now spam is prevented. The only issue is mortar launch sounds, you can fix this by replacing the sound with a blank sound and playing the original sound via outputs.
