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

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)
