game help!!!

im trying to make a rpg but if i
move the man to a tree how do i
make the man stop there??

You seriously want to know??? Because I have developed flawless collision detection...

Depends on how you store the tiles (I wouldn't know how to do it without tiles, so if you aren't using tiles please do ;)). If you have a 2D map of tiles you draw on the screen you can just look in your map if there's a tree like this:

Code:

---

Public Sub Player.Move(iX as Long, iY as Long)
  'For example if 1 is a tree
  If Map( (Player.x + iX) / TileWidth, (Player.Height + iY) / TileHeight ) <> 1 Then
    'No collision so move
    Player.x = Player.x + iX
    Player.y = Player.x + iY
  End If
End Sub

---

Well, that doesn't work perfectly because you have to set a collision range for the player, but I think you'll get an idea how to do it :).

Apollo, how do you do your detection, because mine sometimes fails and units get stuck inside each other :(

Hm.. mine is flawless too ;)

Instead of checking for collision actually on your objects, I check for it a few steps ahead of them, like where they're about to go. And if they try to turn around, I check if there is something anywhere behind them, if not then start moving. I was having the same problem as you Kenny, because I would walk into an object, but get stuck, because the collision flag would be set to true as long as I was inside of the object, so I developed this little idea. It works perfectly for me, and I'm positive it will for you too.

If anyone wants a visual to represent what I'm saying, then I will provide one. Ya just have 2 ask.
