No, the way you set the distance equation up, it is finding the distance to a point in space about half the width of the object in front of it.
To see what i mean, change this:
Position Camera NewXValue(x#,a#,-200),110,NewZValue(z#,a#,-200)
To this:
Position Camera NewXValue(x#,0,-200),110,NewZValue(z#,0,-200)
And make the cross-hairs collide with an object so you can see it side-on... You'll notice that the cross-hairs come out, far infront of the object therefore not really poisitioning it where it should be (although, it does look alright)
Hmm, for the matrix collision, you could try:
Sync On : Sync Rate 0
`Makes a scene with random objects.
Make Matrix 1,2000,2000,10,10
Set Matrix Height 1,0,0,200
Set Matrix Height 1,0,1,200
Set Matrix Height 1,1,1,200
Set Matrix Height 1,1,0,200
Update Matrix 1
For x = 2 To 11
Make Object Cube x,x*Rnd(10)
Position Object x,Rnd(2000),(Object Size(x)/2),Rnd(2000)
Color Object x,RGB(Rnd(255),Rnd(255),Rnd(255))
Next x
`The crosshair's object number would be 100, the characters would be 1
Make Object Sphere 1,50
Make Object Plain 100,10,10
Make Object Plain 101,300,10
`This makes the crosshairs face you.
Yrotate Object 100,90
Fix object pivot 100

But, atm, i can't get it to work properly!!
That's the basic structure that you'll need (i think) so if you can get it working then good on ya!.
Quote: "I found a way to check an object distance from the matrix. As soon as I get back home, I'll show you a snippet. However, if I use that method I'd have to increment the distance of the crosshair by tiny increments until either collision with the matrix happens, or the max_distance is reached. That could be quite a waste of memory come to think of it..."
I'm not too sure what you mean by this, but if it's a different approach to the problem than mine, then I'll be happy to see it
[EDIT]If you set-up your floor etc as objects and planes etc, then you wouldn't have to worry about the matrix intersection etc...[/EDIT]
