This function gets the position of an item of dgs line.

Syntax

float/nil, float/nil, float, float, bool dgsLineGetItemPosition (element line, int index )

Required Arguments

  • line: The DGS Line element.
  • index: The item index.

Returns

Returns 4 floats and a bool indicates start position x and y, end position x and y, and relative. Or 2 nils, 2 floats and a bool if using end position of previous item as start position of current item, false otherwise.

Example

DGS = exports.dgs

local line = DGS:dgsCreateLine(400,200,600,400)
local sinX = math.sin(0/500*4*math.pi)
DGS:dgsLineAddItem(line,0/500,sinX/2+0.5,0/500,sinX/2+0.5,2,tocolor(0,255,0,255),true)
for i=1,100 do
	local sinX = math.sin(i/100*4*math.pi)
	DGS:dgsLineAddItem(line,_,_,i/100,sinX/2+0.5,2,tocolor(i/100*255,255-i/100*255,0,255),true)
end
local sx, sy, ex, ey, relative = DGS:dgsLineGetItemPosition(line,101)
outputChatBox("StartXY ("..(sx or "lastEndX")..", "..(sy or "lastEndY").."); EndXY ("..ex..", "..ey.."); Relative: "..(relative and "true" or "false"))
