Addon Integration

The supplied API offers methods for other addons to integrate with this project. Here you will find a guide on all available features and endpoints.

Weapons use a combination of custom damage types:

DMG Type	Value	Weapons
DMG_MP_NULL	0	Unused
DMG_MP_POWER	1	Power Beam, Super Missile
DMG_MP_WAVE	2	Wave Beam, Wavebuster
DMG_MP_ICE	4	Ice Beam, Ice Spreader

To check for a specific damage type, use: https://wiki.facepunch.com/gmod/CTakeDamageInfo:GetDamageCustom

Adding Threat Indicator Support

To add entities to the threat indication system, use the following stub in an autorun script:

game.MetroidPrimeThreats.Add("entity_class_name")

Adding Log Book Support

There are two ways to add Log Book support to your entities. The first method declares the Log Book data directly in your shared.lua file. The second approach makes use of an autorun script to register your entity into the game. If you are the author of the entity you wish to add support for, the first approach is recommended. If you are not the author, your only option will be the second method.

Method 1
In your shared.lua file, declare the following:

ENT.LogBook = {
	Description = "",
	Left = Material(""), // or nil
	Right = Material("") // or nil
}

Values:

Var	Description
Description	Text to be displayed on the Scan Visor upon scan completion.
Left	Material to be displayed on the left side of the Scan Visor upon scan completion.
Right	Material to be displayed on the right side of the Scan Visor upon scan completion.

Additional Values:

Var	Description
ScanDuration	Time required to scan entity. (Default of 1.33)

Method 2
In your autorun script, add the following stub and change the values to your needs:

game.MetroidPrimeLogBook.Add("entity_class_name", {
	Description = "",
	Left = Material(""), // or nil
	Right = Material("") // or nil
})

VTF/VMT Templates
You can use the following templates for creating your scan images. You can resize the frame however you want as long as your final VTF dimensions are 256 x 512.

small: template
big: template

Here is what your VMT should look like:

"UnlitGeneric"
{
	"$basetexture" "your/texture/path/here"
	"$additive"    "1"
	"$vertexalpha" "1"
	"$vertexcolor" "1"
}

Adding Grapple Beam Anchors

To add grapple beam anchors, use the following stub in an autorun script:

game.MetroidPrimeAnchors.Add("entity_class_name")

Adding Spider Ball Surfaces

The Spider Ball uses surface properties to determine if it can ride along surfaces. To learn more about surface properties, see the following link: https://developer.valvesoftware.com/wiki/Material_surface_properties

By default, the Spider Ball will ride along any metallic surface. To add new surfaces, use the following stub in an autorun script:

game.MetroidPrimeSpiderSurfaces.Add("surface_prop_name")

Adding Lock-On Support

By default, the weapon will use the world space center of an entity to lock on. The API offers a way to define a lock-on attachment. The first method declares the attachment in your Initialize hook. The second approach makes use of an autorun script to register your attachment into the game. If you are the author of the entity you wish to add support for, the first approach is recommended. If you are not the author, your only option will be the second method. Attachments are dynamic, you can change the attachment at any time in your logic as long as it is called server-side. See API section for all available functions in the Entity section.

Method 1
In your Initialize hook:

function ENT:Initialize()

	-- Code.

	if (self.SetLockOnAttachment) then self:SetLockOnAttachment("your_attachment_name") end
end

Method 2
In your autorun script, add the following stub and change the values to your needs:

game.MetroidPrimeLockOn.Add("entity_class_name", "your_attachment_name")

Architecture Overview

There are a lot of moving pieces and a lot of different states to this weapon. The project employs a number of design patterns to aid in its maintainability and debugging. At the core of the system lies four state machine classes responsible for keeping track of all timings and states. The state machines act as the data access layer for all networked properties of the weapon.

Weapon Layer (mp_weapon_powersuit)

This is the default SWEP implementation. This is where all files are loaded. This layer only contains functions relevant to the GLua API and calls to the event layer.

setup.lua : Loads all files and configurations.
shared.lua : Standard implementation, exposes Primary Attack, Secondary Attack and Think logic.
init.lua : Standard implementation, tells the game how the weapon should behave when dropped or equipped.
cl_init.lua: Standard implementation, calls to the rendering stack to display the HUD and how the view should behave.

Events Layer (Logic)

The events layer is divided into four sections:

This layer contains most of the logic for the Power Suit, everything from firing projectiles, movement, target acquisition, etc. This layer communicates with the state machines to update timings and states.

State Machine Layer (Data)

State machines are created inside InstallDataTables and are responsible for installing all necessary network variables onto a Power Suit instance. There are four state machines in total:

This is the data access layer. This is where events and hooks tap into the timings and states of the weapon. State machines act as classes and are exposed to every part of the code in order to maintain separation of concerns. Although you can interact with state machines directly, you should avoid doing so unless you know what you are doing. To access the state machines on a Power Suit instance, refer to the following code:

local weapon = ply:GetPowerSuit();  // Get Power Suit instance using API.

local armcannon = weapon.ArmCannon; // Arm Cannon state machine instance.
local helmet    = weapon.Helmet;    // Helmet state machine instance.
local morphball = weapon.MorphBall; // Morph Ball state machine instance.
local powersuit = weapon.PowerSuit; // Power Suit state machine instance.
