This function gets the position of the specified item of DGS 3D Line.

Syntax

float/nil, float/nil, float/nil, float, float, float dgs3DLineGetItemPosition( element line3D, int index )

Required Arguments

  • line3D: The DGS 3D Line.
  • index: The item index.

Returns

Returns 6 floats indicates start position x, y, z and end position x, y, z of the item. Or 3 nils and 3 floats if using end position of previous item as start position of current item, false otherwise.

Example

DGS = exports.dgs

line = DGS:dgsCreate3DLine(0,0,4,0,0,45,tocolor(255,255,255,255),2,100)
local i = 1
DGS:dgs3DLineAddItem(line,4,0,0,math.cos(i/200*math.pi*2)*4,math.sin(i/200*math.pi*2)*4,0,4,tocolor(i/200*255,255-i/200*255,0,255),true)
for i=2,200 do
	DGS:dgs3DLineAddItem(line,_,_,_,math.cos(i/200*math.pi*2)*4,math.sin(i/200*math.pi*2)*4,0,4,tocolor(i/200*255,255-i/200*255,0,255),true)
end
local sx,sy,sz,ex,ey,ez = DGS:dgs3DLineGetItemPosition(line,1)
outputChatBox("startX:"..sx..";startY:"..sy..";startZ:"..sz..";endX:"..ex..";endY:"..ey..";endZ:"..ez)
