+ Code Snippet

x1#=object position x(1)
y1#=object position y(1)
z1#=object position z(1)
for begin=2 to totalobjects
x2#=object position x(begin)
y2#=object position y(begin)
z2#=object position z(begin)
if x1#=x2#
if y1#=y2-2#
if z1#=z2#
set cursor 10,10
print "object number";begin;" is under you."
endif
endif
endif
next begin

My current savings for the PS3 is: $486.00 out of $600 !!!

Will that work, END?

Sparky's Collision DLL has a raycasting command that does it for you easily though.

Anyway, it depends on what you are using? Is it DBC or DBPro?

If it's the player you could find what is below the camera by using pick object. Something like this-

+ Code Snippet

xang#=camera angle x()
xrotate camera -90
objectbelow=pick object (screen width()/2,screen height()/2,1,1000)
xrotate camera xang#

Use a for/next loop going from every object in your game, then cast an intersection ray below the players object downwards x amount of units. If an intersection occurs with the current object, some part of it is directly below your player. Pseudo;

+ Code Snippet

FOR x = 1 TO 10

   IF OBJECT EXIST(x)

      C# = INTERSECT OBJECT(below user)
      IF C# > 0
         TEXT 0,x*15,"Object "+STR$(x)+" is below you"
      ENDIF

   ENDIF

NEXT x

Or use Sparky's (it's faster). If you use Sparky's, you can assign all of your objects to a group, then just perform one intersection check with that group, and it will return which object from the group is intersected. Would be faster/less lines of code.
