DxDrawMaterialPrimitive

This function draws a 2D primitive shape with material applied to it across the screen - rendered for one frame. This should be used in conjunction with onClientRender in order to display continuously. If image file is used, it should ideally have dimensions that are a power of two, to prevent possible blurring. Power of two: 2px, 4px, 8px, 16px, 32px, 64px, 128px, 256px, 512px, 1024px...

Syntax

bool dxDrawMaterialPrimitive ( primitiveType pType, mixed material, bool postGUI, table vertex1 [, table vertex2, ...] )

Required Arguments

• pType: Type of primitive to be drawn.
• image: Either a material element or a filepath of the image which is going to be drawn. (.dds images are also supported). Image files should ideally have dimensions that are a power of two, to prevent possible blurring. Use a texture created with dxCreateTexture to speed up drawing.
• postGUI: A bool representing whether the line should be drawn on top of or behind any ingame GUI (rendered by CEGUI).
• vertices: Tables representing each primitive vertex, required amount of them is determined by primitive type.

Allowed types

Available primitive types.

More info on primitives may be found on this MSDN site

• pointlist: Renders the vertices as a collection of isolated points.
• linelist: Renders the vertices as a list of isolated straight line segments.
• linestrip: Renders the vertices as a single polyline.
• trianglelist: Renders the specified vertices as a sequence of isolated triangles. Each group of three vertices defines a separate triangle.
• trianglestrip: Renders the vertices as a triangle strip.
• trianglefan: Renders the vertices as a triangle fan.

Vertices format

• posX: An float representing the absolute X position of the vertex, represented by pixels on the screen.
• posY: An float representing the absolute Y position of the vertex, represented by pixels on the screen.
• color (optional): An integer of the hex color, produced using tocolor or 0xAARRGGBB (AA = alpha, RR = red, GG = green, BB = blue). If it's not specified, white color is used.
• u: An float representing the relative X coordinate of the top left corner of the material which should be drawn from image
• v: An float representing the relative Y coordinate of the top left corner of the material which should be drawn from image

Returns

Returns a true if the operation was successful, false otherwise.

Example

-- Load the texture
local texture = dxCreateTexture("myTexture.png")

-- Function to render a textured triangle
function renderPrimitive()
    if texture then
        -- Draw the primitive using the "trianglelist" type
        -- 3 vertices, each with 4 numbers: {x, y, u, v}
        dxDrawMaterialPrimitive("trianglelist", texture, false, {100, 100, 0, 0}, {300, 100, 1, 0}, {200, 300, 0.5, 1})
    end
end

-- Add an event handler to render the primitive every frame
addEventHandler("onClientRender", root, renderPrimitive)
