So I've looked around and searched for a way to link and place objects like you would a road in SC4 or any other city builder game. THe only thing I came across was tiling with a texture or with multiple textures for various types of transits. But no where have I found ways to create 3d roads and such. Has any one had any luck in this area or is there a tutorial I can look over that I don't know about. What ever I come up with from any one or any tutorial I'll share in return... I just need a little direction

This may help a little. It's a grid-based track game + source code. I had a whole routine dedicated to comparing each track cell and working out which directions I needed to the track to travel based on it's neighbours.

Thats close to what I mean. The path following will be custom however as I havent invested in DarkAI on this computer. If there's any one else who can provide examples it would be greatly appreciated.

Wee! okay, so I've gotten the object(S) to loop and place on a matrix (which in the simulation game I am designing) will be placed over the terrain ONLY when you select a tool unless otherwise an option for the user.

My trouble now is storing the X, or Y values for the mouse based on the position of the camera from the matrix... in other words:

1 2 3 4 5 6 7 8...
2 O
3 B
4 J
5 E
6 C
7 T
8

See how the object is placed on 2,2 and ends on 7,2... I need to store the 2 value based on the place you click on the matrix relative to the camera position and NOT STORE the 7 value (so you draw a straight line rather than some criss-cross mumbo-jumbo diagonal-hell ) You can then- based on the position of the mouse and matrix- rotate the object... this can be used to create |,/,-,\, angled objects or even more indepth object angles based on the mouses position. (My explanation is a little confusing so theres an image you can look at and understand better

Simply program it so that on the first click it sets a flag:



To reset it, set the variable "flag" to 0.

When the flag is equal to 1, draw the line:



Presumably you'd want to use an object rather than a line:



You'd be using the grid coordinates rather than mousex() and mousey() if you're working in a 3D world. Just do a simple Search/Replace.

Good luck,
Calcyman

That was VERY helpful Calcyman!!! But what if I wanted to just repeat an object over and over... like segments and then when I click again, bind all of these objects into one object or turn it into one mesh and delete these objects? How would I repeat these objects in a line relative to the first click? (IE... like the 2d line's pixels... how do I do that in 3d w/ the same object repeating... the object number would have to be an iNC value... but beyond that my mind is lacking) I'll fool around with it and see what I come up with.

Okay so I can use all of the above (sorry for 2X post) but what I really need now is an understanding of vertex commands. This will help when a piece of road or what ever needs to make a <90 turn. Not completely right angled intersections, transitions from a ground freeway to an elevated highway and so on. It would be awesome if some one who has done or knows how to draw objects like a line(s) without the rough edges. ANY help is welcomed and encouraged as is any help understanding the vertex commands.
