I am looking at making a doom style fps and I found out that they use a process called raycasting.
While researching possible ways to do that in dbpro I came across this command - http://dbprohelp.wikia.com/wiki/PICK_OBJECT
I was wondering if I could use that command to create a raycasting engineout of a 2d map.

Cheers in advance

I would think the way to do this is to use textured planes pointing toward the camera to display the NPC's. You would then raycast from the tip of the player's gun, following the angle of the gun out a certain distance and you would check (via raycast) to see if any of the NPC planes are intersected (and the walls too, of course). I suppose you could use the Intersect Object command to do the same thing.

I have no idea what you are talking about with regard to a 2D map and I can't see how pick object would help with that.
So many games to code.....so little time.

Yeah, INTERSECT OBJECT is the way to go for bullet collisions, and some people even use it for determining the ground height in relation to the player.
It's one of the best native DBP commands I've used. No need for special engines or maps this way!
