Renderer

Renderer namespace with useful drawing functions.

caution

Please do not overuse these in your final production scripts as these calls made from Lua may cause heavy impact on performance.

tip

For optimal performance prefer using Renderer.DrawEffectCircle function in your final production scripts.

  position: Vector2,
  size?: number,
  color?: number
) → void

Argument	Type	Description
text	string	Text you want to display.
position	Vector2	On-screen position for your text. Starts from top-left corner.
size?	number - float	Font size. 12 by default.
color?	number - D3DCOLOR	Font color. White by default.

Draw basic ImGui text.

note

Unlike most other Renderer functions, all ImGui functions must be used in OnImguiDraw callback.

---

DrawWorldText

Renderer.DrawWorldText(
  text: string,
  position: Vector3,
  offset?: Vector2,
  size?: number,
  color?: number
) → void

Argument	Type	Description
text	string	Text you want to display.
position	Vector3	World position.
offset?	Vector2	On-screen offset. Vector2(0,0) by default.
size?	number - float	Font size. 12 by default.
color?	number - D3DCOLOR	Font color. White by default.

Draw basic ImGui text in game world.

note

Unlike most other Renderer functions, all ImGui functions must be used in OnImguiDraw callback.

---

DrawEffectCircle

Renderer.DrawEffectCircle(
  hash: number,
  position: Vector2,
  radius: number,
  colorInfo?: ColorInfo,
  effectType?: EffectType
) → void

Argument	Type	Description
hash	number - integer	Unique fnv hash.
position	Vector2	Position.
radius	number	Radius.
colorInfo?	ColorInfo	ColorInfo struct. White solid by default.
effectType?	EffectType	Shader effect type. GlowingCircle by default.

Draw fancy shader circle.

caution

It is important to use unique fnv hash for this. Please use unique prefix when generating this hash.

Example: Draw fancy shader circle around selected target.

local MyGlowingCircleHash = Game.fnvhash("Example_MyGlowingCircle") -- This must be unique hash per drawing. Use unique prefix.
local color = Renderer.ColorInfo.new(0xFFFFFFFF, 0xFF5555FF, Renderer.GradientType.Linear)
local radius = 100
Callback.Bind(CallbackType.OnDraw, function()
    local tar = Game.GetSelectedTarget()
    if tar and tar:IsValid() then
        Renderer.DrawEffectCircle(MyGlowingCircleHash, tar.position2D, radius, color, Renderer.EffectType.MagicalCircle)
    end
end)

---

CalcTextSize

Renderer.CalcTextSize(text: string, fontSize: number) → number, number

Argument	Type	Description
text	string	Text string.
fontSize	number - float	Text font size.

Returns calculated text width and height.

Example: Draw a centered text indicator under player, showing whether he is inside enemy turret range or not.

local fontSize = 16
Callback.Bind(CallbackType.OnImguiDraw, function()
    local text = TurretTracker.IsPlayerInsideTurret() and "Inside" or "Outside"
    local tX, tY = Renderer.CalcTextSize(text, fontSize)
    Renderer.DrawWorldText(text, Game.localPlayer.position, Math.Vector2(-tX/2, 0), fontSize)
end)
