Re: [Audyssey] Conceiving Level Maps

```Hi Jim,

The reason I do that is because I store everything like doors, walls,
fire traps, chasms, etc in a 3d array. Basically, how it works is I
take the current directionand coordinates and calculate a vector along
that direction x units away to find out where the player will be next.
I then check the array to see what is there and take whatever action
is necessary.```

There is nothing specifically wrong with the way you do colision
detection, but I can think of some limitations. For example, in some
games a player might have to use explosives to blow a hole in a wall,
detection is hard coded like that it isn't going to be easy to remove
a section of the wall and leave part or most of it standing. With an
array all you need to do is calculate the blast radius of the
explosion and remove however many elements necessary to make that size
hole in the wall. Make sense?
