Minetest Mod - Shooter API [shooter]

Depends: default

Handles raycasting, blasting and audio-visual effects of dependent mods

Crafting

Gunpowder

1 x Coal Lump + 1 x Clay Lump = 5 x Gunpowder

output = "shooter:gunpowder 5",
type = "shapeless",
recipe = {"default:coal_lump", "default:clay_lump"},

Configuration

Override the following default settings by adding them to your minetest.conf file

Enable automatic weapons

Uses globalstep to detect left mouse button

shooter_automatic_weapons = true

Enable admin super weapons

Allows admins (server priv) to shoot all guns automatically Requires shooter_automatic_weapons to be true

shooter_admin_weapons = false

Enable node destruction with explosives

shooter_enable_blasting = true

Enable Crafting

shooter_enable_crafting = true

Enable hit particle effects

shooter_enable_particle_fx = true

Enable protection

Requires a protection mod that utilizes minetest.is_protected()

shooter_enable_protection = false

Particle texture

Particle texture used when a player or entity with the 'fleshy' armor group is hit

shooter_explosion = "shooter_hit.png"

Allow node destruction

shooter_allow_nodes = true

Allow entities

Defaults to true in singleplayer mode

shooter_allow_entities = false

Allow players

Defaults to false in singleplayer mode

shooter_allow_players = true

Round update time

Maximum round 'step' processing interval, will inversely effect the long-range velocity of the virtual projectiles. This should always be greater than the dedicated server step time

shooter_rounds_update_time = 0.4

Camera Height

Player eye offset used for rayasting and particle effects

shooter_camera_height = 1.5

Methods

• shooter.register_weapon(name, definition): Register a shooting weapon. -- See "Weapon Definition"
• shooter.get_configuration(config): Loads matching config settings into a table ref config
• shooter.spawn_particles(pos, particles): Adds particles at the specified position
  • particles is an optional table of overrides for shooter.default_particles
• shooter.play_node_sound(node, pos): Plays the registered 'dug' sound for the node at pos
• shooter.is_valid_object(object): Returns true if the object can be damaged
• shooter.punch_node(pos, spec): Punches the node at pos with the spec group capabilities
• shooter.punch_object(object, tool_caps, dir, on_blast): Punches the object
  • Returns true if the object is damaged
  • object: Object to punched, not checked for validity!
  • tool_caps: Tool capabilities of the weapon uesd -- See "Weapon Definition"
  • dir: Unit vector pointing from the source of the punch to the object
  • on_blast: Respect entity on_blast damage callback
• shooter.fire_weapon(player, itemstack, spec): Adds a 'round' with spec to the processing que
• shooter.blast(pos, radius, fleshy, distance, user): Create explosion at pos
  • radius: Blast radius in nodes
  • fleshy: Damage to inflict on fleshy objects: (fleshy * 0.5 ^ distance) * 2
  • distance: Area of effect for objects
  • user: A player reference, used for protection and object damage
• shooter.get_shooting(name): Returns true if player name is holding the left mouse button or nil
  • Requires shooter_automatic_weapons to be set true
