HU/dxDrawPrimitive

This function draws a 2D primitive shape across the screen - rendered for one frame. This should be used in conjunction with onClientRender in order to display continuously.

Szintaxis

bool dxDrawPrimitive ( string pType, bool postGUI, table vertice1 [, table vertice2, ...] )

Kötelező paraméterek

pType: Type of primitive to be drawn.
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.

Engedélyezett típusok

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.

Visszatérési érték

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

Példa

This is a small example that creates trianglefan primitive with vertices in places that user clicks. It assigns every vertice random color.

local vertices = {}
function onClick(btn, state, x, y)
	if btn ~= "left" then return end
	if state ~= "up" then return end
	local vertice = {x, y, tocolor(math.random(255), math.random(255), math.random(255))}
	table.insert(vertices, vertice)
end
addEventHandler("onClientClick", root, onClick)

function draw()
	dxDrawPrimitive("trianglefan", true, unpack(vertices))
end
addEventHandler("onClientPreRender", root, draw)
