How to draw cones dynamically by TE
This article mainly introduces how TE dynamically plots cones, which is very detailed and has a certain reference value. Friends who are interested must read it!
In the secondary development of TE, the three-dimensional cone can be plotted, and the conical drawing can be carried out in accordance with the way operated in TE.
The implementation of the javascript code in BS is as follows:
Events to add actions:
/ / left button, right button, real-time refresh
Sgworld.AttachEvent ("OnLButtonDown", OnLButtonDown)
Sgworld.AttachEvent ("OnRButtonDown", OnRButtonDown)
Sgworld.AttachEvent ("OnFrame", OnFrame)
/ / left button event
Function OnLButtonDown (Flags,X,Y)
{
/ / the sign of whether to start plotting
If (cflag)
{
Var Iwordpoint= sgworld.Window.PixelToWorld (Xmeny Yphai0)
If (Cone==null)
{
Var nLineColor = 0xFF0000FF
/ / create a conical object
Cone=sgworld.Creator.CreateCone (Iwordpoint.Position,1,0,nLineColor,nLineColor,12,0, "circle")
}
Else
{
Var dis = sgworld.CoordServices.GetDistance (Cone.Position.X, Cone.Position.Y, Iwordpoint.Position.X, Iwordpoint.Position.Y)
/ / judge the circle at the bottom first
If (hflag)
{
Var dis1 = sgworld.CoordServices.GetDistance (0, Cone.Position.Y, 0, Iwordpoint.Position.Y)
Cone.Height=dis
Cflag = false
}
/ / set the radius and height of the cone
If (Cone.Height = = 0 percent percent flag) {
Cone.Radius = dis
Cone.Height=dis
Hflag=true
}
}
}
}
/ / right-click event to end the cone drawing
Function OnRButtonUpp (Flags,X,Y)
{
Cflag = false
Cone=null
Hflag=false
}
/ / Real-time refresh event
Function Onframe ()
{
If (cflag)
{
/ / Radius transformation of the bottom circle
If (contains contains null)
{
Var Imousinfo = sgworld.Window.GetMouseInfo ()
Var Iwordpoint = sgworld.Window.PixelToWorld (Imousinfo.X, Imousinfo.Y, 0)
/ / change the radius according to the distance
Var dis = sgworld.CoordServices.GetDistance (Cone.Position.X, Cone.Position.Y, Iwordpoint.Position.X, Iwordpoint.Position.Y)
If (Cone.Height = = 0 percent percent flag) {
Cone.Radius = dis
}
If (hflag)
{
/ / height change
Var dis1 = Imethod.getdistance (0, Cone.Position.Y, 0, Iwordpoint.Position.Y)
Cone.Height=dis1
}
}
}
}
