Render API

Use the Render API from Render() to draw overlays in screen, world, or minimap space.

Lua signatures are strict

The C++ render functions use default arguments internally, but Lua does not receive those defaults unless an overload is bound. Pass every parameter shown below.

Coordinate Spaces

Space	Use for
Screen	HUD, labels, fixed UI.
World	Unit highlights, placement markers, tactical overlays.
Minimap	Strategic indicators on the minimap.

Screen Space

Function	Signature	Description
`GetScreenSize`	`()`	Returns the current screen size as `Vector2`.
`IsOnScreen`	`(position)`	Returns whether a `Vector2` screen position is visible.
`RenderText`	`(text, position, size, color, center, border)`	Draws screen-space text.
`RenderLine`	`(from, to, color, thickness)`	Draws a screen-space line.
`RenderCircle`	`(position, radius, color, thickness, segments)`	Draws a circle outline.
`RenderCircleFilled`	`(position, radius, color, segments)`	Draws a filled circle.
`RenderRect`	`(from, to, color, rounding, roundingCornersFlags, thickness)`	Draws a rectangle outline.
`RenderRectFilled`	`(from, to, color, rounding, roundingCornersFlags)`	Draws a filled rectangle.

World and Minimap Space

Function	Signature	Description
`IsWorldPosOnScreen`	`(worldPos)`	Returns whether a `Vector3` world position is visible.
`WorldToScreen`	`(worldPos)`	Converts a `Vector3` world position to a `Vector2` screen position.
`WorldToMinimap`	`(worldPos)`	Converts a `Vector3` world position to a `Vector2` minimap position.
`GetZoom`	`()`	Returns the current camera zoom.
`GetCameraPosition`	`()`	Returns the camera position as `Vector2`.
`RenderWorldLine`	`(from, to, color, thickness)`	Draws a world-space line.
`RenderWorldRect`	`(worldPos, width, height, color, thickness)`	Draws a world-space rectangle outline.
`RenderWorldRectFilled`	`(worldPos, width, height, color)`	Draws a filled world-space rectangle.
`RenderWorldCircle`	`(worldPos, radius, color, thickness, segments)`	Draws a world-space circle outline.
`RenderWorldCircleFilled`	`(worldPos, radius, color, segments)`	Draws a filled world-space circle.
`RenderWorldText`	`(text, worldPos, size, color, center, border)`	Draws text anchored in world space.
`RenderObjectBounds`	`(object, color, thickness)`	Draws an outline around an object's bounds.
`RenderObjectBoundsFilled`	`(object, color)`	Draws a filled overlay over an object's bounds.
`RenderMinimapDot`	`(worldPos, radius, color)`	Draws a dot on the minimap.
`RenderMinimapLine`	`(worldPosFrom, worldPosTo, thickness, color)`	Draws a line on the minimap.
`RenderMinimapRect`	`(worldPos, width, height, color, thickness)`	Draws a rectangle on the minimap.
`RenderMinimapRectFilled`	`(worldPos, width, height, color)`	Draws a filled rectangle on the minimap.

Example

function Render()
    local player = GetAssignedPlayer()
    if not player then
        return
    end

    local color = Color(255, 0, 0, 120)
    for _, tc in ipairs(player:GetTownCenters()) do
        RenderObjectBounds(tc, color, 2.0)
        RenderWorldText("TC", tc:GetPosition(), 14.0, Color(255, 255, 255, 255), true, true)
    end
end
