API reference 1.0

Core

• vesta.api.major, vesta.api.minor
• vesta.api.script_dir — absolute directory of the active package
• vesta.api.data_dir — absolute private writable data directory of the active package
• vesta.log(text)
• vesta.events.on(name, callback) -> token
• vesta.events.off(name [, token]) -> bool

Game

• vesta.game.snapshot()
• vesta.game.radar_snapshot()
• vesta.game.world_to_screen(vec3)
• vesta.game.trace_ray(start, finish)
• vesta.game.bomb_damage(position [, site, eye_angles, ducked])
• vesta.game.predict_grenade(origin, velocity, kind [, remaining_lifetime])
• vesta.game.radar_overview(map_name)
• vesta.game.penetration_damage(start, finish [, target_handle])

Config and storage

• vesta.config.get(path)
• vesta.config.set(path, value)
• vesta.config.patch(table)
• vesta.config.snapshot()
• vesta.config.schema()
• vesta.storage.get/set/remove(key [, value])

UI

• vesta.ui.text(id, label, value)
• vesta.ui.button(id, label [, action_text])
• vesta.ui.toggle(id, label, default)
• vesta.ui.slider(id, label, default, min, max, step)
• vesta.ui.select(id, label, options, default_index)
• vesta.ui.input(id, label, default_text)
• vesta.ui.color(id, label, {r,g,b,a})
• vesta.ui.keybind(id, label, default_vk)
• vesta.ui.separator(id, label)
• vesta.ui.get(id), vesta.ui.consume(id)

External helpers

• vesta.helpers.start(relative_ps1, args) -> bool [, error]
• vesta.helpers.copy_text(text) -> bool

Only the built-in web radar sees vesta.helpers (see the sandbox section of the README); for every other script the table is absent. start accepts only a .ps1 file inside the active package directory and returns immediately after creating the external process.

Bundled assets

• vesta.assets.weapon_font() -> string

Returns the bytes of the same TTF Vesta uses for built-in weapon and grenade icons. A script can write the string in binary mode and use the font in a local UI or web frontend.

Draw

• line(x1,y1,x2,y2,r,g,b,a[,thickness])
• rect/filled_rect(x,y,w,h,r,g,b,a[,thickness])
• circle/filled_circle(x,y,radius,r,g,b,a[,thickness])
• text(x,y,text,r,g,b,a)
• world_line(vec3,vec3,r,g,b,a[,thickness])
• world_text(vec3,text,r,g,b,a)
• load_texture(relative_path) -> texture_id | nil,error
• image(texture_id,x,y,w,h[,r,g,b,a])
• panel(x,y,w,h,title[,accent_r,g,b,a])

Input

• is_down(vk), binding(action), key(vk,down), tap(vk)
• mouse_move(dx,dy), mouse_button("primary"|"secondary",down)
