Is there a command to know if the camera see an object?

And is there a command to know if there is not something between 2 objects?
Intersect object is no good, because you must test every objects to know if any object is between the 2 points

Get Sparky collision Dll. It's free and does super-fast ray tracing and will give you a list of objects numbers between two points, nearest first.

Boo!

Check out the OBJECT IN SCREEN () and OBJECT VISIBLE() functions.

As far as checking for intervening objects, I think that checking every object is pretty much what you're going to have to do. There are a few ways to do this. You could store the list of object numbers in an array and use a FOR/NEXT loop to check using INTERSECT OBJECT(). You could use Sparky's which I believe has commands that will automate this task for you.

Expanding on Jane Doe:

OBJECT IN SCREEN(object): Tells if an object is within the bounds of the screen (Press F1 on the command for details). Returns a 0 if the object isn't in bounds, and a 1 if it is

OBJECT VISIBLE(object): Tells if an object is hidden (using the HIDE OBJECT command) or not. Returns a 0 if the object is hidden, and a 1 if it isn't. (in my opinion the help files don't explain it well enough)

Think of 0 as false and 1 as true.

Good luck

Yes, Sparky rules.

OBJECT IN SCREEN and OBJECT VISIBLE are no good.
INTERSECT OBJECT can work, but I use it in other my routines.
In the our case INTERSECT OBJECT need too much for next cicles (a test for every object).

I did not want it, but at last I must use Sparky's DLL.

I do not understand why DBP can not have native commands to make so usefull tasks.

Thank you Sparky, again.
