For the past month or so, (very small in programmer years ) I have been trying with too much over exertion to figure out how to link an object (Lets just say on a 2X2 meter tile- on 2048X2048 terrain-) that sits 15 meters above the ground and is 2X2 meters across. What I need to have happen is, the user clicks a tile and my elevated Highway will be placed on the map. But I need the verticies to line up and be able to cap the beginning and end of the highway with a start cap and end cap. How do I continually place an object linked to the previous one and apply an end and start cap RELATIVE to the N,S,E,W, Direction the verticies of the highway model after it's drawn?

I don't think I'm understanding here... Are you asking how to get the coordinates of a tile on your terrain?

Here's what I mean... I have an object. How do I determine the tile (or location... I can determine tile placement at a later date) being clicked IN 3D space? I also need my object to link together like a spline... so it would first place a start cap (an object I made) the repeating object (Like my el. Highway) and an end cap (for when you've placed all that you've desired)

Now I know very well about pick object and so on. But I've also figured a bit of code out that can position objects relative to the screen size... or in other words:

(Note I am really using terrains with a matrix overlayed for a grid)
X=Matrix Position X(1)
Y=Matrix position Y(1)
Z=Matrix position Z(1)
X=MOUSEX()
Z=MOUSEY()

SET CURSOR 10,10
Print MC
Print X
Print Z
--------

The problem lies with my matrix and terrain size paired to the screen width and height. Since my display= 1280x1024, The object can only be placed within those dimensions AND the screens pixel count originates from the opposite side of the 3d space dimension- so if you move your mouse to the top of the screen, the object is moved downwards...

SO I am asking two things. 1, how to make an object and repeat it to the mouse's position and 2, how to flip the screens pixel count so as 0,0 = 0,X,0 in 3d space AND not limit to the size of the screen. IT IS very confusing I know... but just make a terrain larger then the display mode and paste that code above... then try to position an object within mouseX and MouseY... you'll completely understand-

Okay, I've figured out how to invert the mouse's Y axis... searching yielded several snippets and I coded what I needed for the outcome I desired from several of them. But let me elaborate just what I mean by linking the objects.


I need to get my mesh or object to link to the previously drawn object or mesh and if at all possible -Yeah I'll do a search unless told otherwise- be able to create a curve system where- if a key is pressed and the "highway" tool is selected,- the object will curve if a location(s) on the terrain is clicked. (IE Bazier Curve)

What I am most eager to learn and know is: what is the best method to link the objects together via vertex location w/in the mesh/object or from the object/mesh's limb(s)- with little code (not for lack of skill but for little confusion in code as there will be multiple tools of this type)- and how the object/mesh should be placed in your opinion... click to click or drag and drop? PM/Email me if you'd rather not share any information publicly.
