HU/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...

Szintaxis

bool dxDrawPrimitive ( primitiveType pType, mixed material, bool postGUI, table vertice1 [, table vertice2, ...] )

Kötelező paraméterek

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 vertice, required amount of them is determined by primitive type.

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 vertice, represented by pixels on the screen.
posY: An float representing the absolute Y position of the vertice, 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 a true if the operation was successful, false otherwise.
